Dallas HVAC Contractors Know the Best Insulation for the Job

Tuesday 26 May 2015 13:27
Written by

03_13_13Dallas HVAC contractors can easily advise you on the best type of insulation for your home. Energy efficiency in your home can be dramatically improved by increasing the amount of insulation in your walls, attic and floors.

Two common choices are fiberglass and cellulose insulation. While both types can be effective, in many cases, fiberglass is the better choice.
  • Fiberglass maintains its insulating qualities better: Insulation stops heat from moving from place to place, keeping it inside in the winter and outside in the summer. The effectiveness of insulation is measured by its R-value, which indicates how well it resists heat flow. Cellulose insulation tends to settle after installation, which means it loses thickness and, as a consequence, loses R-value. Fiberglass insulation does not settle or thin out, which means it retains its R-value and insulating qualities.
  • Fiberglass is better for fire safety: Fiberglass insulation is made from spun glass, sand or other inorganic material that does not burn easily, making it a better choice for fire safety. Cellulose insulation is made from ground up newspaper. Though cellulose insulation is treated with fire retardants, the underlying material is flammable.
  • Fiberglass is water- and moisture-resistant: Fiberglass insulation can get wet or damp if exposed to moisture, but the material does not ordinarily absorb or hold water that reduces its insulating abilities. Cellulose, being made of paper, can easily absorb water and lose its ability to insulate.
  • Fiberglass is not attractive to mold and insects: The inorganic material of fiberglass insulation is not a food source for mold or insects, so there is little chance of bugs or mold in fiberglass. Cellulose is a common insect food source and can be attractive to hungry bugs or mold spores.
Crawford Services, Inc. is one of the Dallas HVAC contractors that customers can rely on to provide a full range of sales, maintenance and repair services that keep home heating and cooling systems running at their best and most efficient. Contact us today for more information on home insulation and for expert help deciding if fiberglass or cellulose insulation is the best choice for your project.

Dallas Heating and Air Conditioning Professionals Know the Value of Air Filtration

Tuesday 26 May 2015 13:25
Written by

Dallas heating and air conditioning services cover a wide range of issues, including temperature control, energy savings and indoor air quality. Because clean indoor air is such a major factor in home comfort, air filtration merits special consideration.

A good filtration system offers a number of benefits:
  • Longer HVAC system life – A minimum level of filtration is necessary to keep out dust, pollen and other airborne debris that could accumulate in the ductwork and system components. Certain components, such as the blower motor, are likely to fail early if not protected.
  • Greater system efficiency – A cleaner system runs more efficiently and therefore costs less to operate. The American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) has found that dirty coils and blowers can reduce system efficiency by up to 40 percent.
  • Cleaner air – Medium- to high-efficiency filters capture smaller particles and remove them from the air. This means less pollen, pet dander, mold spores, dust mites and other irritants floating around to aggravate your allergies or asthma.
If you're looking for a good particulate filter, a Dallas heating and air conditioning expert can help you choose one. The Minimum Efficiency Reporting Value (MERV) also gives you an easy way to compare the efficiency of these filters.

MERV 1 to 4 – These are the lowest-efficiency filters, usually disposable fiberglass panels or paper filters. Because they can only catch particles larger than 10 microns, their primary use is to protect your HVAC system. They do almost nothing to clean your air. If kept clean, however, these cheap filters will maintain good airflow in your system.

MERV 5 to 8 – These medium-efficiency filters help improve air quality. They trap particles down to 3 microns in size, including mold spores and pet dander. These are usually pleated (extended surface) filters.

MERV 9 and over – At the lower end of this range are the better quality medium-efficiency filters. Filters with a MERV above 12 are considered high-efficiency.

A word about HEPA filters

With a MERV between 17 to 20, High-Efficiency Particulate Air (HEPA) filters are the most efficient of all. While they capture very small contaminants such as some viruses and smoke particles, they also slow airflow and can reduce system efficiency. Because of this, not every HVAC system can be fit with a HEPA filter. If you're considering buying one, consult with a Dallas heating and air conditioning technician to make sure the filter won't impair your system operation.

For even better indoor air quality, consider installing an electronic air cleaner to trap very fine particles and/or a UVGI air cleaner to neutralize biological contaminants.

If you'd like help choosing filtration options for your heating and cooling system, contact us at Crawford Services. In the Dallas area, we provide a wide range of value-driven HVAC solutions.

Indoor Air Quality in Your Dallas Home Can Be Improved This Spring With 7 Simple Strategies

Tuesday 26 May 2015 13:23
Written by

05_07_13Maintaining indoor air quality is about more than keeping your Dallas area home smelling fresh. Your home's air quality affects you and your family's health, as well. To keep your home's indoor air clean and healthy, try these simple strategies:
  1. Maintain your air filters – Once a month, inspect your HVAC system's air filter to keep the equipment clean and efficient. Change the filter when it looks dirty. For cleaner air, use a pleated or electrostatic filter. If you're unclear about the right filter for your home's cooling and heating equipment, consult with a trusted HVAC specialist.
  2. Keep the dust down – Feather dusters and most cloths just spread dust, and chemical sprays can irritate your airways. Microfiber cloths pick up dust with no need for sprays. Better yet, they're also reusable.
  3. Close your windows at night – Pollen is most widespread late at night and in the early morning, so close your windows overnight if you have allergies. If you want to use your A/C overnight, consider installing a programmable thermostat and setting the system to turn off a few hours before dawn.
  4. Optimize your ventilation – The vents in your kitchen and bath clear out odors and reduce humidity, but they waste a lot of energy just to provide a small amount of ventilation. For a continuous flow of fresh air and better indoor air quality, an energy-recovery ventilation system will provide a more energy-efficient option for your Dallas area home.
  5. Control humidity – Relative humidity much higher than 50 percent will encourage mold growth. Airborne mold spores can aggravate respiratory problems. To keep your indoor humidity down, consider installing a whole-house dehumidifier.
  6. Try a UV-light air cleaner – Ultraviolet (UV) light, the same type of light as sunshine, stops the reproduction of microorganisms such as mold, bacteria and viruses. A UV-light air cleaner fits in your HVAC system and improves indoor air quality by neutralizing microorganisms in the air passing through.
  7. Test for radon – Radon, a natural yet cancer-causing gas, can enter your home through the ground or well water. Contact the Texas Department of State Health Service's radon program for a test kit or call an HVAC expert to have your home professionally tested.
For expert advice on efficient ways to improve your indoor air quality, please contact us at Crawford Services. Our well equipped, experienced technicians provide reliable HVAC services in the Dallas area.

Air Duct Cleaning Helps Keep Allergies at Bay in Your Dallas Area Home

Tuesday 26 May 2015 13:17
Written by

05_09_13Air duct cleaning is an effective way to improve the air quality in your Dallas area home. All of the air that heats or cools your living spaces travels through the air ducts, which means that keeping this air distribution network clean and free of contaminants can reduce the effects of allergies, asthma and other respiratory conditions.

Material such as dust, dirt, lint, hair, fibers, insect or rodent nests, mold and other contaminants can accumulate in your ductwork. When your HVAC system is first turned on for the season, these particulates can be dislodged by airflow and sent into your home's interior. Large accumulations can continue to contaminate your air over a long period. Professional air duct cleaning will remove any built-up contaminants or sources of particulates.

Air duct cleaning has not been shown to prevent any particular health conditions, according to the U.S. Environmental Protection Agency. However, the EPA recommends duct cleaning under three specific conditions:
  1. Mold is growing inside the ductwork or on your HVAC equipment and is visible on duct surfaces or system components.
  2. Ducts are inhabited by insects or small animals that have left behind nests, fur, feces or other contaminants.
  3. Ducts are fully or partially blocked by debris, which will restrict airflow and significantly reduce HVAC system effectiveness and efficiency. A sign of this might be debris blowing out of registers.
If your ducts are emitting large amounts of particulates, are producing unusual odors or seem to be clogged, a duct cleaning may be a wise choice. Air duct cleaning also lets an HVAC expert examine your duct system from end to end. This provides a chance to find any ductwork problems such as broken seals, loose connections, or detached sections that need repair.

Choose your duct cleaning contractor carefully and beware of overly positive claims about the benefits of duct cleaning. Check contractor references and qualifications and make sure the company will correct any damage to the ductwork the cleaning process may cause.

In Dallas and North Texas, Crawford Services, Inc. provides professional heating and cooling services for residential and commercial customers. Contact us todayfor more information on air duct cleaning or to schedule a duct cleaning appointment at your convenience.

A Dehumidifier Can Balance Out Your Indoor Air When High Humidity Is a Problem

Tuesday 26 May 2015 13:15
Written by

05_21_13A dehumidifier can help even when you don't have high humidity outside. Today’s airtight homes conserve energy but also accumulate water vapor. Most of this originates from household appliances, human activities or other sources within the home. The U.S. Environmental Protection Agency recommends maintaining indoor humidity levels between 40 and 60 percent for greatest comfort, interior air quality and heating/cooling effectiveness. Without a dehumidifier, that’s often a tough standard to meet in a well-sealed house with little natural ventilation. Some of the sources of high interior humidity include:
  • Showering, laundering and cooking.
  • Water vapor emitted by normal human respiration and perspiration.
  • Moisture migrating up from a moist basement or unconditioned crawl space or down from the attic.
  • Unvented natural gas appliances such as stoves and space heaters.
Consequences of excessive interior humidity include condensation damage such as structural rot and staining on walls and other surfaces. Increased occurrence of mold and mildew growth, as well as the proliferation of airborne mold spores, dust mites and the allergic reactions associated with these contaminants, may also occur. Other physical symptoms including a general feeling of discomfort and poor sleep may be noted by occupants, as well.

There's also an energy-efficiency and cost component of air that's too moist during the cooling season. Humid air feels warmer than dry air, so in homes with muggy or clammy air, occupants are more likely to crank up the A/C. When the humidity is reduced, you can raise the temperature on the thermostat, without any loss of comfort, and save on your monthly electric bills.

Controlling high humidity levels at the source can be a challenge. Fortunately, a whole-house dehumidifier gets the job done even when the sources of humidity can’t be entirely eliminated. A whole-house dehumidifier installed inside your forced-air heating and cooling ductwork treats the entire volume of air in your home as it circulates through your ducts. Activated by a humidistat that continuously senses moisture levels in the air, the technology maintains the humidity level you set automatically with no further user input. The system is permanently plumbed into your household drain system so there’s no emptying of condensation pans or other chores associated with portable room dehumidifiers. Operation is quiet and there’s no footprint taking up space in individual rooms.

Crawford Services provides comprehensive HVAC and plumbing sales and service to Dallas area homeowners. Ask us for more details about the comfort and household benefits of a whole-house dehumidifier.

Air Filtration Maintenance: How to Care for Your Electronic Air Cleaner

Tuesday 26 May 2015 13:13
Written by

06_06_13Air filtration with an electronic air filter is one of the most efficient and convenient methods available for improving your home's air quality. To do their job, these air cleaners need only basic maintenance. That primarily means keeping the pre-filter and collector plates free from the dust and pollen we see a lot of in North Texas.

Your owner's manual should tell you how often to clean your filtration system. Typically, your system will need cleaning every three months. Always check your owner's manual before choosing a cleaning method, since these systems can vary substantially.

Using a garden hose – For a quick, simple way to clean your pre-filter and collector plates, take them outside and spray them down with a garden hose. Use light water pressure to avoid damaging the collector plates. Vacuuming the pre-filter is another way to keep it clean so it continues to provide good air filtration.

In a tub – On some air cleaner models, the collector plates can be washed in a bathtub, laundry tub or other large container. Place the plates in the container and add enough very hot water to cover the plates. Then add 3/4 cup automatic dishwasher detergent per plate. Agitate the water to dissolve the detergent and let the plates soak for 15 to 20 minutes. To rinse the plates, soak them in pure water for another five to 15 minutes. Remove the plates to drain. If the draining water looks or feels soapy, rinse the plates again.

In the dishwasher – Use this method for the collector plates only (not the pre-filter) and only if your air filtration equipment's owner's manual recommends it. Place the collector plates in the dishwasher. Run the dishwasher as usual, but stop it before the drying cycle and remove the plates. If the plates go through the drying cycle, any remaining debris may become baked on.

Let the pre-filter and collector plates dry thoroughly before you replace them.

The IAQ of Your Dallas Home Can Be Improved With UV Lights

Tuesday 26 May 2015 13:09
Written by

06_18_13IAQ, or indoor air quality, is a significant health issue for an American population that spends most of its time indoors. In many cases, the air filter in your HVAC system or a more advanced air filtration device takes care of removing solid particulates such as dust, pollen, fibers, animal dander, and other contributors to allergies and respiratory problems. However, getting rid of particles is only one aspect of effective IAQ and contaminant control. Air also contains living organisms such as viruses, germs, bacteria, fungi and mold spores that can cause disease and severe physical discomfort. To keep these health hazards under control and ensure the best IAQ possible, it's a good idea to add ultraviolet (UV) lights to your existing HVAC system.

UV lights are extremely powerful disinfectants that can kill biological contaminants and micro-organisms in your indoor air. While ultraviolet light cannot be seen by the human eye, it's still highly effective. In current applications, UV lights are used in places where a clean, sterile environment is critical, such as hospitals, food production facilities and manufacturing plants. UV light is a form of radiation that is highly effective at eliminating the micro-organisms that can cause infection, disease and related medical issues.

In residential settings, UV light systems are installed in conjunction with your forced-air heating or cooling system. The light units are mounted within the ductwork so that all of the air circulating through your HVAC equipment can be exposed to the UV light. When micro-organisms are exposed to the UV light, it kills many of them outright. In the ones that aren't killed, the light causes severe damage to the organisms' DNA, the genetic material necessary for reproduction. With their DNA destroyed, micro-organisms cannot establish a population and reproduce in your home or in your body, where they cause disease and discomfort. When these biological contaminants are removed from your home's environment, your IAQ will be dramatically improved.

Remember that direct exposure to UV light is necessary for it to be effective. You'll want to leave installation of UV light disinfectant systems to your local trusted indoor air quality expert. UV light is most effective against germs, bacteria and mold, though it has no effect on non-organic particles. An additional air filtration or purification system is recommended to achieve the highest possible level of IAQ.

Crawford Services, Inc. is a leading source of HVAC and indoor air quality services in the Dallas area. Contact us today for more information on improving IAQ and how UV light can dramatically boost indoor air quality by removing potentially harmful micro-organisms.

Indoor Air Quality Can Be Controlled in Your Dallas Home This Spring With 9 Tips

Tuesday 26 May 2015 13:04
Written by

06_26_13Your home's indoor air quality can be affected by factors present in nearly every room in the house. By using one or more of the following nine techniques, you can substantially improve the air quality in your home this spring and beyond.
  • Maintain clean HVAC system filters: Your air conditioner contains a filter that removes particles from the airflow moving through the system. Dirty filters are less effective at removing these particulates and could make indoor air quality worse if material they've captured re-enters the airflow. Check your air filters at least monthly and change them when they're dirty.
  • Add an air purification system: An air purification system provides additional effective air filtration. A whole-house air cleaner or purifier will dramatically improve indoor air quality by removing tiny allergens, airborne contaminants and micro-organisms from your home's air.
  • Install a germicidal UV light: Ultraviolet (UV) light is an extremely powerful disinfectant. UV light systems are available that you can add to your existing air conditioning system. The lights destroy potentially harmful micro-organisms in your indoor air, such as mold, viruses and germs.
  • Take control of moisture: Reduce the amount of moisture in bathrooms, kitchens and elsewhere. Run ventilating fans to move moisture outdoors. Clean up spills quickly. Don't let wet clothes or towels pile up. Install a whole-house dehumidifier to reduce humidity levels throughout your home.
  • Change your kitchen sponges: Kitchen sponges used for cleaning are prime environments for bacteria and mold that can be transmitted to your home's indoor air. Replace kitchen sponges at least weekly.
  • Take off your shoes: Your shoes can carry significant amounts of dust, dirt and other particulates into your home. Practice the habit of leaving your shoes at the door when you come in.
  • Clean bedding regularly: Your blankets, sheets and other bedding can be a source of dust, dust mites, fibers and other airborne particulates. Wash bedding regularly with hot water to eliminate dust mites and clean away fibers, dust and other particles. Find zippered allergy-proof cases and coverings for your mattresses and pillows.
  • Dust regularly with microfiber cloths: Weekly dusting will eliminate considerable amounts of dust and dirt from your home environment. Use efficient microfiber cloths that pick up and remove dust without using cleaning sprays or chemicals.
  • Close the doors and windows: Probably the simplest way to improve indoor air quality is to keep your doors and windows closed, which prevents pollen, allergens, dust and other material from getting into your home and into your air.

Your Indoor Air Quality Could Use a Boost This Summer: 3 Add-ons to Consider

Tuesday 26 May 2015 13:03
Written by

07_18_13Diminished indoor air quality is more likely to become a problem for you the more time you spend indoors this summer. Particulates in your home's air could aggravate allergies or respiratory conditions. Excess humidity could damage your belongings or even your home's basic structure. Disease-causing micro-organisms could invade your body and make you miserable. Here are three effective add-ons for your HVAC system that can improve indoor air quality.

1. Dehumidification. Humidity inside your home normally increases during the summer. Along with the weather-related increases, normal sources of indoor moisture such as cooking, showering and clothes washing will keep adding humidity to your indoor air. A tightly sealed home, while energy efficient, will be more likely to hold excess moisture.

Whole-house dehumidifiers substantially reduce moisture and improve indoor air quality. They are installed within the airflow of your forced-air cooling system. As the air that cools your home circulates, it also passes through the dehumidifier, where moisture is removed before the air continues on into your home.

Indoor relative humidity should be somewhere between 30 to 50 percent. Controlling your indoor humidity will decrease the physical effects often felt in humid environments, such as tiredness and aggravation of respiratory conditions. It will prevent the growth of mold, insects, mildew, bacteria and other pests that thrive on moisture. It also will reduce the possibility of moisture damage to books, papers, wood, furniture and electronics.

2. Filtration. Your air conditioner provides basic air cleaning through its air filters. That is why indoor air quality requires regular changes of the filters in your HVAC system. If you need or want a greater level of air filtration and particle removal, an air purification or filtration system will help. These devices are also placed within the airflow of your central air conditioning system. The higher-quality filters in these units capture and hold particulates such as dust, pollen, mold, animal dander, fibers and other solid contaminants.

Some filtration systems are available with activated charcoal filters that can remove fumes and odors in addition to particulates.

3. Ultraviolet (UV) light systems. UV light systems are a powerful weapon against biological contaminants and disease-causing micro-organisms. These units are designed to treat the air coming from your HVAC system with ultraviolet light. As UV light shines on micro-organisms, it either kills them outright or damages their DNA, which makes them unable to reproduce. Organisms that cannot reproduce cannot multiply and spread, preventing them from causing disease.

How Your IAQ Can Be Improved by an ERV

Tuesday 26 May 2015 13:01
Written by

1_29_13The IAQ (indoor air quality) of your North Texas home is one of two major concerns when dealing with a sweltering summer. It may not be the most obvious summer problem, but the average home's IAQ is relatively poor, leading to allergies, asthma, and illness. The summer's high humidity makes your indoor air quality even worse.

The other concern is keeping your energy bills down while cooling your home. Fortunately, there's a solution that can help you deal with both problems simultaneously. It's called Energy Recovery Ventilation.

Your indoor air quality is likely much worse than the quality of the air outside. If the same air cycles through your A/C over and over again, eventually it becomes stale. So one of the keys to raising your IAQ is keeping a steady supply of fresh air coming in from outdoors, while expelling stale indoor air back outside.

An ERV, when operating during the cooling process, takes the heat from the incoming air and transfers it to the outgoing air. The two streams are run side by side, separated by a thin wall. As they pass by one another, a heat exchanger is used to condition the warm incoming air using the cool air that's leaving your home. That way, your air conditioner doesn't have to work as hard to cool your home to its desired temperature. The process is reversed in the winter, with the ERV removing heat energy from the indoor air as it flows outside.

An ERV can recover and reuse up to 80 percent of the energy from the air before it's expelled back outside. In addition, it can transfer some of the water vapor from the humid incoming air into the outgoing air, before the air conditioner dehumidifies it further, making your home feel fresher and cooler.

An ERV is a great way to lower your energy bills and raise your IAQ. The one drawback, though, is that it can be expensive to install, especially when compared with other systems. However, one type of ERV set-up can make use of your existing ductwork, saving on installation costs.

For more advice on raising your IAQ and lowering your energy bills this summer, contact our experts at Crawford Services, Inc. We proudly serve the HVAC needs of the Greater Dallas Metro area.

Duct Cleaning: What are the Benefits?

Tuesday 26 May 2015 12:59
Written by

Duct cleaning is always a topic of heated discussion among friends and neighbors.Will it really benefit you and your family? What is really being done?

Knowing how the duct cleaning process works is the first step in understanding the need for your home to have a professional duct cleaning service performed. Over time, dust, dander and allergens build up in your ducts. These same substances also cling to other places - like your cooling coil, heating coil, blower and heat exchanger.

02_19_13All of these airborne particles collect and inhibit the performance of your HVAC system. If you are going to have your air ducts cleaned, then it stands to reason that you want your home to have healthier air and that you want your climate control system to work more efficiently. Right?

Of course you do. Who wouldn't want to live better and save money? Duct cleaning should be viewed as an all-inclusive cleaning job, not just a duct cleanout. A certified and reputable company can come out to your home and give you an estimate that includes duct cleaning as well as internal HVAC component cleaning.

Just look at it this way. Your air ducts got dirty for a reason. Our homes have become tighter than ever before because we strive to be more efficient with our energy bills.Once dust, dander and other airborne pollutants invade our home, they stay there.Your HVAC system runs off a supply and return system, meaning air is pulled from the return ducts, conditioned for heating or cooling, then sent back into the home through the supply ducts.

The air in your home (along with all of the pollutants) is circulated throughout your home five to seven times a day on average. That means that all of the dust and debris that did not catch onto the internal HVAC system parts or onto the internal walls of the air ducts, goes back into your home then the cycle repeats itself.

The simple fact is, no matter how much time you spend in your home, there is no way to stop dust and debris from entering and getting trapped there. That means that it has to go somewhere. If it is not airborne and circulating, then it has attached itself to something, most likely inside your HVAC system. This is why duct cleaning becomes a must for homeowners. For some people, the dust is a fairly harmless nuisance. But, for those who have autoimmune deficiencies,asthma or chronic respiratory illness, duct cleaning can substantially improve their lifestyle.

Inspect for yourself and see if your ducts have a dirty buildup in them. You might think that is an impossible task, but not really. Just take your camera phone and,with the flash on, stick it into your air duct and take a picture. If there is buildup of any kind, you will quickly understand why a duct cleaning service is needed. But, there are other reasons that duct cleaning is considered an important aspect tohealthier living. A good example of this would be air leaks in your ducts. As we all know, when you run your air conditioner, your condenser coil removes moisture from the air and discards it through a condensate drain. If there is a leak in your airduct, then there is going to be mold growth because the moisture is not making it to the condenser coil, thus leaving the structural members in the proximity of the leak exposed to a steady stream of moisture. Over time, this moisture will rot the wood and/or insulation and also accumulate mold. The mold can then circulate throughout your home.

It is very important to get any mold accumulations cleaned out of your air ducts as well as the wood and insulation. Sealing ducts like this would also be highly advisable. You are not only providing a safe haven for mold and rot, but you are losing any conditioned air you produce and forcing your HVAC system to work harder to provide optimal comfort.

Duct cleaning can also help ensure that rodents and insects are not dwelling in your air returns. These critters are public enemy number one when it comes to spreading disease. To sum it all up, it would be in your best interest to call an experienced and licensed HVAC company out to make sure that your home air is healthy for you and your family. Your health and financial well-being will be better off.

Good, In-Home Air Quality Could Benefit the Health of Everyone in Your Home

Tuesday 26 May 2015 12:56
Written by

The air quality of your home is important for the health and comfort of everyone who lives there. Air quality is, naturally, at its least healthy during the winter months when we tend to keep ourselves locked inside, shutting out the cold (and fresh) air. Sealing your homeagainst the winter cold is good for keeping heat inside, but it can also provide harmful pollutants and indoor allergens with the perfect place to thrive.

air-duct-cleaningIndoor pollutants can cause a particular hazard to children, asthma sufferers, and the elderly, although the sad truth is that some of the adverse health effects from poor air quality in the home only appear many years later - and after much exposure. Because wespend much more time indoors than recent generations, these risks are increasing all of the time. Modern homes are also much more airtight thanks to things like double glazing and insulation. The factors that adversely affect air quality do vary considerably -- everythingfrom dust mites in our furniture and carpets to pet dander, even the paint on the walls.But, there are ways you can help improve the air quality in your home and to provide a healthy environment for your family.

• Keep it clean. It can be very tempting to put things off, especially in the winter months, when all we really want to do is to stay warm and cozy by the fire. Regular cleaning can help to reduce the irritants and allergens in the air. Dust surfaces with a damp cloth, rather than something like a feather duster which really just redistributes the dust back into the atmosphere. Pay particular attention to theareas which are out of sight and difficult to reach – ceiling fans and refrigerator tops are particularly easy to ignore.

• Pets. Your pets will probably spend much more time indoors during the winter time; after all, they want to stay warm, too! This will probably lead to more dust, dander,and fur, so remember to groom your pet regularly, give him plenty of baths, and don’t forget to give the dog bed frequent washes in very hot water. Another good tip is to not allow your pets into your bedroom.

• Circulation. This is another tip for improving the air quality in your home. Don’t be afraid to open the windows every now and then for a little bit of fresh air, even on a cool day. This is especially important when you’re cleaning, painting, or cooking. Exhaust / extractor fans are also important to take away the grease and odors while you cook.

• Clean your floors regularly. Instead of using chemicals, which can add to the problem, you should use a strong vacuum cleaner with a HEPA filter to prevent any dust which has been sucked up from being blown out again. Mopping the floor after vacuuming will take away the last traces of dust which have been left behind. And, plain water will do the job just fine, there’s no need for soaps or chemicals.

• Door mats. These should be placed on the outside of your home in order to keep as much dust and dirt outside as possible and improve the air quality in your property. This will make a significant difference in the amount of dirt that is walked into your home.

• Humidity level. Your home should also be kept to a healthy humidity level. Mold and dust mites thrive in moisture, so you should aim for the humidity to be kept around 30 percent, or 50 percent at the maximum level. A dehumidifier is a worthwhile investment to reduce the moisture in the air and help to control the allergens.

• Smoking. We don’t need to tell you that smoking is bad in so many ways, but another way to help to improve the air quality in your home is to make it a strict smoke-free zone. Cigarette smoke is packed with chemicals (around 4,000 of them) and a smoky environment has been proved to increase the risk of children developing many illnesses, including respiratory infections, ear infections, asthma,SIDS, cancer, and more.

• Fragrances. Don’t overdo the synthetic fragrances, which are designed to make your home smell good. Synthetic fragrances in air fresheners and other cleaning products are simply sending chemicals out into the air and affecting the air quality. This istrue for many products including fabric softeners, air freshener sprays and solids,detergents, dryer sheets . . . in fact just about everything which is designed to make your home smell nice may actually be harming the air quality.

As you can see, improving the air quality in your home really does have many benefits for all members of the family.

Spring Cleaning: What About Indoor Air Quality?

Tuesday 26 May 2015 12:54
Written by

Improving indoor air quality can be an important part of spring cleaning – and there’s much moreto it than washing chair covers and giving the windows a polish. One of the best ways to improve the indoor air quality of your home is to have your HVAC regularly serviced by an approved, trained and licensed technician. Not only will the air quality of your home significantly recover through this service, but it will also help to improve the efficiency of your AC system, while cutting down on energy bills and even increasing the longevity of your system.

If your HVAC system is regularly maintained it will help to reduce the dust within your home (big plus) and reduce the poisonous carbon monoxide gases from the exhaust – improving indoor air quality is a winning solution in many areas.

Improving the indoor air quality of your home falls into three basic categories;

• Reducing the amount of pollution in your home.

• Ensuring that your home is properly ventilated.

• Utilizing some of the proven products available on the market for improving the indoor air quality of a property

Here are just a few spring cleaning tips to help make and keep your home spic and span - with good air quality.

• Have your HVAC system regularly inspected and maintained, and make sure that the filter is replaced as often as necessary. If the air filter in your HVAC system is clean, it will work more efficiently to trap things like viruses, bacteria, pollen and dust. These are the main culprits that can significantly harm the quality of the air in your home and lead to poor health and allergies.

• Take off your outdoor shoes at the door and switch to indoor shoes or slippers. The soles of outdoor shoes carry lots of different contaminants from outside into your home and can spread them all over the house given the chance. Change your shoes at the doorstep to help to prevent this from happening.

• The constant humidity within your home is an important factor in making sure that your indoor air quality is good. If humidity is kept between 30 – 50 percent, it will help to prevent any mildew or mold from growing in your home. If necessary invest in a portable dehumidifier for a little extra help, unless you have a whole house dehumidifier – use whatever is necessary depending upon the size and age of your property and your location.

• Make sure that you wash your bed sheets every week using hot water – it may soundrevolting, but beds contain 2 million dust mites on average (yuk). And, that’s not the worst of it - their cast-off skin and droppings are a major cause of allergic reactions.

• Regular dusting in the home can help to improve the indoor air quality of your home, but don’t just swirl the dust around in the air for it to resettle as soon as your back is turned.

Use a microfiber cloth or electrostatic cloth, which actually picks up the dust and doesn’t just redistribute it.

• As soon as you have dusted, it’s time to vacuum – make sure that the fan on yourthermostat is switched to on while you vacuum to get rid of many of the dust particles which are produced as you vacuum. The exhaust of your vacuum can produce quite a lot of dust –so leave the fan on for a few minutes after you’ve finished to catch the last of the culprits.

• De-cluttering your home can help to make a big difference to your indoor air quality. Knick-knacks don’t just collect dust, they also discourage some homeowners from dusting as regularly as they know they know they should. It is much easier to control the dust within your home if there are not any additional ornaments or needless clutter all over the place.

• “Au natural” cleaning can also help to improve the indoor air quality in your home. The problem with many modern household cleaners and chemicals, including air fresheners and candles, is that they themselves may contain chemicals which can severely detract from the air quality in your home. Many supermarkets provide natural cleaning supplies; you will also find plenty of natural cleaners in your refrigerator and kitchen cupboards if you just know where to look. Vinegar is a master at cleaning the home - mix with water and pop it into a spray bottle and you can safely clean, disinfect and deodorize many areas of the home (don’t worry, the smell disappears as the vinegar dries). Other fabulous natural cleaning products include lemon juice, which is terrific for hard water deposits and soap scum – do remember that lemon juice has bleaching properties so test out a small area before putting it onto your favorite furnishings. Baking soda is another terrific natural cleaning product which can help to maintain good indoor air quality in your home. Simply put some into a box and pop it into the fridge and / or freezer and it will absorb nasty odors. If some part of your home needs to be deodorized turn to the baking powder – smelly sneakers, laundry baskets, trash cans. .

• Deodorizing candles might seem like a good idea, but they really are not. Try to avoid using things like burning candles, smoking and burning incense inside the house.

There is a good range of products available which can help you to determine and improve the indoor air quality within your home. Radon gas detectors, carbon monoxide gas detectors and HEPA air filters can all help to keep your family safe and your home clean and healthy. The use of Ultra Violet lights is also effective in dealing with the invisible microbes – they are so small that you can’t see them, but the damage they can do to the comfort and health of your family is enormous.

Spring cleaning  time is certainly upon us, so please bear in mind these tips before you sta

An Air Purifier Will Keep the Allergies Out This Spring

Tuesday 26 May 2015 12:52
Written by

indoorairqualityAn air purifier is definitely the most effective method for keeping your home and your family allergen free this spring. Whole house air purifiers trap particles as the air passes through the filter in the air conditioning, central heating system or the forced air heating system in your home.

Portable air purifiers are also available which, although not as efficient as a whole house air purifier,do provide a good alternative to properties which do not have central heating or air conditioning.

Portable Air Purifier or Air Cleaning Units

Houses which do not have central air conditioning or heating systems can have the option of a whole house unit which is free standing and may typically involve installation in the attic with ducting to each individual room, or alternatively portable room air filters which can be moved from room to room as required.

Most portable air cleaning units use HEPA filters which utilize pretty powerful fans (more powerful than is possible with a general furnace application) or ion air purifiers which utilize electrostatic precipitators. These do not need to have the powerful fans which make them much quieter than the HEPA filters.

Some portable air purifier units can be incredibly noisy, which is one big disadvantage. The reason for the noisiness is simple – these units require a lot of wind in order to push the air through the finest filters on the air purifier unit. One possible solution is to switch the unit on to high during the daytime when there is more background noise around and turn to low during the night when all is quiet.

The price of portable air cleaning units varies quite widely depending upon the type of unit youchoose. You can pay as little as $150 or as much as up to $1500. Those which utilize replaceable HEPA filters often have an added yearly expense of around $40 to $100 for the specialized filters.

The way to determine whether you have a suitably sized air cleaning unit for the room is to check the CADR – the clean air delivery rate – which should be around 2/3 of the area of the room. A room measuring 300 square feet would need a CADR of at least 200.

Whole House Air Purifier Unit or Filters

Whole house air purifiers are the most efficient and most popular type of air purifier – built into the ductwork of the air conditioning or forced air heating systems and trapping particles as they pass through the filters. There are four different types of these whole house air purifier units:

Flat Filter Units

If your property has a forced air type furnace already installed, then you do have some sort of air filtration system in place already. The system will be fitted with a fiberglass filter which does need to be changed every month; in fact, you can change it even more regularly if you remember – the more the better. If the filter gets clogged up with dust it will stop the furnace from working efficiently and can cause it to overheat. The filters are actually designed to protect the furnace from the damaging effect of large dust particles and can also help to make your home a dust free zone for longer periods of time.

Electrostatically charged pleated filters can attract allergens such as pet dander and pollen and need to be changed every couple of months for the best results. Don’t worry, it won’t break the bank, they will only set you back about $15.

Extended Media Air Purifier Filter

This type of air purifier looks a little like a pile of furnace filters all on top of one another and measures around 8 inches. These boxy “accordions” are significantly more effective than thetypical filters made from regular fiberglass. One drawback is that you need a professional to install them; the larger box structure must be plumbed into the existing ductwork in your property with adaptations made as necessary. Once you’ve had this type of air purifier filter installed, you can replace them yourself. Installation costs may be as much as $600 but once the large work has been done, they only cost around $60 per year to replace.

Electric Air Purifier Filters

Now we’re getting high tech! These units are sometimes known as electrostatic precipitators and,just like the extended media filter, must be incorporated and plumbed into existing ductwork. These rather ingenious devices help to keep the allergies out of your home by passing high voltage currents through the air, putting an electrical charge onto the particles. A collector is positioned with an opposite charge to gather up the particles in a similar way to a magnet. These are super efficient and even work on smoke particles which may be too small for other types of media filter.

Some experts quote this type of air purifier as up to 30 times more efficient than a traditional fiber glass filter. Yes, they really are that good. Another advantage of this type of device is that there are no filters to replace although the aluminum plates which collect the particles will need a wash every few months with soapy water. This type of air purifier unit costs between $600 and $1000 for purchase and installation, and operates using a 120 volt electric outlet.

Ultraviolet Air Purifier Filters

If you are as worried about germs as you are about pollen, pet dander and other allergens, then this could be the air purifier for you and your family. Ultraviolet filters are typically built in components onto an air conditioning or heating system, although they can be purchased as add-ons for between around $500 and $800. Hospitals use this type of air filtration system, particular in tuberculosis wards as the UV light can zap the airborne viruses and bacteria. In order for the system to zap the bugs, however, the bugs must pass through the filtration system; there is no protection against germs if someone sneezes right next to you, no matter how expensive or efficient the ultraviolet air purifier is.

Choosing the right air purification for your home often requires additional navigational help from an HVAC specialist. But, the extra up-front expense can save your family a lot of money and sick days as they filter out the allergens and viruses that often make you sick, or at the very least sneezy and uncomfortable.

New Construction Trends: Wine Cooler Refrigeration

Tuesday 26 May 2015 12:32
Written by

Wine cooler refrigeration units are becoming increasingly popular in private homes. You can actually install a wine cooler refrigeration unit anywhere in the home, although this decision will have an impact on the ease of construction and the cost of running and maintaining the wine storage room.

Wine cooler refrigeration units do not have to be placed in the cellar, but they often are for very good reason. It is advisable to place the unit in the coolest part of the home with the most humidity. If your chosen room already has temperatures around 55 degrees – 58 degrees F then you won’t need such a large wine cooler refrigeration.   Ambient temperatures in other portions of the home can hover around the 80 degrees F mark.  The warmer the natural temperature of the location the larger unit you will need in order to maintain the optimum temperature – think of it like a giant refrigerator, the warmer the temperature outside the harder it will need to work.  Cellars are traditionally cold and damp, making them the perfect location considering the optimum humidity needed is between 50 percent and 70 percent.

There are a number of steps which must be taken when you decide to install wine cooler refrigeration in your home, whether you choose to take on the task yourself or call in the experts to see to everything for you.

builders-homeConcrete walls must be sealed and studded out depending upon which type of construction methods you use. Your chosen room must not only be kept at the correct temperature and humidity, but you must also protect the rest of the house from the vapor, so insulation is vital. The theory is the same as insulating your home to cut down on your monthly outgoings and utility bills.  It is also imperative that you check permitting requirements and adhere to all building codes before you start work on your wine cellar. If you choose a professional company to do the job for you they should be able to advise you on what’s needed.

Wine cooler refrigeration unit installation needs to utilize studs and soffits which will cover over the piping, ducting and all other fittings involved in the process.  You should also pay attention to the lighting needs at this stage of the construction; the light fittings will need to be insulated.

The next portion of the process to think about is the cooling unit -- you will also need some sort of humidification system if you live in an extremely dry climate or choose a very dry room in the house. Some wine cooler refrigeration units have built in humidity management systems, some do not. One other thing to consider is the noise element – some cooling systems can be quite noisy and are best placed outside the home if possible. You will also need to remember that you’ll need an electrical power point close by and possibly a drain line, as a condensation drain may be needed.

Wine Cooler Refrigeration Insulation and Barriers

Most wine cooler refrigeration units use either spray foam or employ a 6ml barrier utilizing fiberglass batts. The most expensive method is generally the spray foam, but this eliminates any potential problems with puncturing the barrier while running wires, inserting screws or installing plumbing.

When it comes to electrical outlets you need to take one or two things into consideration. First of all you must make sure that the location of your electrical outlet is within the parameters set by your local building codes and regulations, the other thing to remember is that once you have installed the racks in your wine cellar you could end up obstructing the electrical outlet. Remember that you need an electrical supply for your refrigeration, humidifying and lighting.

Once all of this technical part of the construction has been completed it is time to think about the wall coverings in your wine room. The materials you choose must be resistant to the humidity necessary for keeping the wine room within its optimum operating parameters – water resistant walls can be used similar to those used in kitchens and bathrooms.  Once the wall is screwed into place you should paint with exterior, water based paint – if you use solvent or oil based paints the odor may linger longer than it would in any other well ventilated room in the house.

Once the walling is installed it is time to see to the flooring of the wine cellar. Again, this needs to be resistant to the high humidity levels which are vital for the success of the wine room – carpets are certainly not suitable, you could also have problems with vinyl flooring, as the moisture will eventually cause the mastic used to fit the vinyl to buckle and move around. The best options for flooring in your wine cooler refrigeration room are:
  •         Cork
  •         Hardwood
  •         Porcelain tiles
If you go for the hardwood floor option, leave about a half inch expansion room around the perimeter of the room – if you have the time, leave the wood in the wine cellar for a couple of days before installing it on the floor to give it the chance to acclimatize and adapt to the conditions.

Your wine cellar door should be exterior grade, complete with weather stripping and a door sweep along the bottom – you’ve got to keep the cool, moist air inside the room and the warmer air in the remainder of the house outside the room. Solid wood doors work well; glass doors are fine just so long as you have a panel which has been thermo-paned.

Eventually the time will come when you’ve fitted the wine cooler refrigeration unit and the walls, floor, ceiling, lighting and door are all in position.  Then it’s time to choose the fun part – fitting your wine room with racking. Hardwoods which are popular for wine racks include mahogany and redwood – both having the resistant properties needed to withstand the damp, cold environment of the wine cellar.

Now, the only thing left to add is the wine!

"Impressive sales presentation and technical analysis. Very pleased with how system was installed from a technical standpoint. Very pleased with performance of downstairs system. Need to make sure that estimate of how long the install would take is done up-front. Estimates given for arrival of technicians was often missed, sometimes by more than an hour making it difficult to plan personal time and schedule time off-work. In more than one case people would arrive without the needed equipment to address the completion of the job. Made me think about the one hour heating and air commercials I hear on the ticket and how nice that would be. We had both the downstairs and upstairs units replaced. Upstairs problem areas were identified up front (tonnage was too low and return and supply was lacking). After replacement - have struggled to address problem areas identified initially."

Avoid Costly Dallas Air Conditioning Repair With AC Maintenance

Tuesday 26 May 2015 11:14
Written by

Will Dallas air conditioning repair costs keep you from enjoying a balmy Texas springtime? Not if you practice some basic annual maintenance on your Dallas HVAC systems first. By running a regular maintenance program, you can prevent air conditioning repair problems, and make sure you stay comfortable all year round.

Perhaps not surprisingly, many homeowners in Dallas don’t think to have their air conditioners serviced until it breaks down. Unfortunately, this usually happens at the peak of the cooling season, when they’re running their system the hardest. By scheduling AC maintenance in the spring, you can prevent getting caught in this last-minute rush for Dallas air conditioning repair and service.

If there is something wrong with your A/C, wouldn’t you rather catch it now, instead of risking a breakdown during the hottest part of the year? In addition to saving yourself on sweltering inconvenience, catching small problems early allows your technician to make necessary adjustments and prevent costly and unnecessary system damage down the road. This saves you money in repairs and prevents the need for early component replacements.

Consider some of the items we cover in this thorough inspection: We test electronics for operational safety, we clean the heating coils, and inspect the ducts for efficiency, sealing any and all leaks to prevent energy loss and dust infiltration. We also check your refrigerant charge, searching out and repair any leaks in your system, and change the air filters so they provide cleaner air in your home.

Doing this improves the maximum efficiency of your HVAC system over the long term, and helps you avoid costly air conditioning repair sooner than you need it.

In addition to saving you on the expenses associated with emergency air conditioning repair calls and early replacements, springtime maintenance will also enhance A/C efficiency, increasing your comfort and reducing your energy costs. What’s more, by scheduling annual maintenance, you alleviate the burden that cooling season puts on your components, and reduce their wear and tear.

An energy savings agreement with Crawford Services qualifies the homeowner to get priority service on any repairs, no overtime or after hour charges, 15% discount on all air conditioning repair, and a 1 year guarantee on all repairs or workmanship.

Crawford Services provides heating, plumbing, and air conditioning repair and services to all of North Texas. Call us at (214) 271-8800 to get started today.

Expert AC Repair — How Does An HVAC Contractor Measure Up?

Tuesday 26 May 2015 11:06
Written by



Hiring an AC repair contractor for home heating, cooling, ventilation or refrigeration job means getting expert HVAC service from a knowledgeable professional who can service, repair or install equipment safely and efficiently.

Consider these factors when looking for an AC repair technician.

Ask friends and neighbors for their recommendations for AC repair contractors they have hired in the past. By asking people you trust, you're more likely to find a good AC repair contractor. If necessary, ask friends online in various social networks.

Ask at least three potential contractors for detailed written bids. A contractor who responds to a formal bid demonstrates genuine interest and professionalism. If they cannot be bothered to submit a bid properly or on time, that tells you how reliable they'll be.

Contact your state and local offices to check on the contractor’s licensing status. State licenses are required, and some cities may require additional licensing or credentials. If a contractor is unwilling to show his licensing information, that's a deal breaker. Similarly, find out whether they are fully bonded and insured.

Ask potential contractors for references from local customers. Contact at least three of these references and ask detailed questions. An AC repair tech with a large number of satisfied customers means they do good work.

Check and understand the financial terms being offered. See if there needs to be a down payment made before work begins and if there will be a schedule of payments. Make sure there is a cancellation period during which you can cancel the contract without penalty — three-day cancellation periods are common.

Finding a qualified AC repair technician is not too difficult, provided you do some proper initial research. Not only will you be satisfied, but you can rest more easily knowing you have an AC repair tech that is committed to their work and doing the best job they can.

Avoid Water Heater Repair With Annual Service and Maintenance

Tuesday 26 May 2015 11:01
Written by

Water heater repair can be inconvenient and costly, often coming at the time you needed a quick shower because you were running late to work. But you can avoid the headache of water heater repair if you just get an annual inspection done by trained professionals.This service is particularly important in an area such as Dallas-Ft. Worth, where hard water sediment is a common problem, and water heater repair goes on constantly.

For gas water heaters, cleaning the burners is part of professional water heater maintenance. The service technician will check flues and vents for any sign of leaking exhaust fumes.

Both electric and gas heaters contain a “sacrificial anode” suspended inside the tank. This metal rod is subject to corrosion, a consequence of electrolytic processes as water heats. Without the anode, the tank itself will corrode. A water heater repair professional can check the anode’s condition and replace the rod.

The annual inspection also involves draining and refilling the water heater. Once the heater is empty, the service technician will clean the inside and thereby increase the water heater’s life span and efficiency.You can prolong water heater life with some routine water heater maintenance of your own by performing these simple tasks:

To minimize the buildup of calcium carbonate sediment, partially drain the water heater two to four times a year. First shut off the heater, then attach a garden hose to the drainage valve near the tank bottom. Open the valve and drain off a bucketful of water.

Periodically test the T&P valve, near the top of the tank. Pull up part way on the valve’s lever and release. Lifting the lever should cause gurgling, as some water drains from the vertical tube attached to the valve. If this doesn't happen, contact your water heater repair tech at Crawford Services to have the valve replaced.You can avoid water heater repair with some basic maintenance and the annual checkup to keep small problems from becoming big ones. Just work with water heater professionals like Crawford Services to keep everything running properly.

Upgrading Home Insulation? You’ll Reap These 3 Benefits

Tuesday 26 May 2015 11:00
Written by

Many North Texas homes need to add more insulation to reap the full benefits that come from adequately insulating your house. Upgrading home insulation is a relatively simple way to increase your house's overall energy efficiency. Here are three of the primary benefits of adding insulation in key areas throughout the home. 
    • Increased comfort levels — Proper levels of insulation keep heated air inside the home during the winter and prevent warm air from entering your house during the summer. The best places to place extra insulation include attics and basements, floors over unheated or open spaces, and the walls between a living space and an unheated area such as a garage.
 
    • Health — Increasing home insulation can provide important health benefits for everyone. A Harvard study found that in the wider population, upgrading home insulation results in a reduction in the amount of energy needed to heat and cool homes. This means a reduction in health problems caused by power plant emissions. The study found that better insulation ultimately leads to reduced asthma attacks and cardiovascular problems, in addition to lowering the number of days individuals restrict their daily activities for health reasons.
 
    • Cost savingsHeating and cooling your house is responsible for at least 38 percent of a typical home's total energy usage and probably a good deal more than that. By making your home more energy efficient through increasing the level of insulation, you will need less energy to heat and cool the house, which lowers your monthly utility costs.
 In addition to these three important benefits, adding insulation also has the advantage of reducing the level of noise in the home, as sound moves far more easily between uninsulated areas than insulated rooms or spaces. Extra insulation also reduces condensation, the process where water vapor turns into a liquid, on walls and ceilings. For more information on upgrading home insulation and other issues related to home comfort, please contact us at Crawford Services. We provide superior HVAC services to the Dallas-Fort Worth area.

Our goal is to help educate our customers in North Texas about energy and home comfort issues (specific to HVAC systems).

High Energy Bills? 3 Tips To Control Energy Costs

Tuesday 26 May 2015 09:15
Written by

Our long, hot North Texas summers leave many homeowners wishing for a way to lower their high energy bills. The same applies to our chilly winter months. Cooling and heating your home uses a substantial amount of the energy that you pay for each month. By evaluating the areas of your home that affect home comfort, you can find ways to reduce those high energy bills.

Your cooling and heating equipment is a logical place to start. For example, you can see significant savings by upgrading to a high-efficiency air conditioner or heat pump if your present equipment is more than a decade old. If an upgrade is not in the cards this year or if you have already upgraded and want to save even more money, preventative maintenance can help your system run more efficiently. Replacing the filters, lubricating the motor and other maintenance tasks help your air conditioner, heat pump or furnace run more smoothly and use less energy to cool and heat your home. As a bonus, HVAC appliances that receive routine tune-ups typically last longer and break down less often than those that don't receive maintenance.

Another area to look at is the amount of insulation you have and where it's located. The best place to start is your attic, where adding insulation is relatively simple and has the best payoff in terms of energy savings. The hot summer sun beating down on your roof can cause your attic to reach 150 degrees or higher. Having a layer of insulation between your living space and all that heat will ease the load on your air cooling system. Also considering adding insulation to your exterior walls, basement and between floors for added energy savings.

You should also evaluate the state of your ductwork. As much as 30 percent of your heating and cooling costs can be attributed to lost energy from leaking or uninsulated ducts. Minor duct leaks can be repaired with mastic sealant. Avoid using duct tape, which won't last very long.

For more information about lowering your high energy bills or any other HVAC matter, please contact us at Crawford Services, Inc. We are proud to serve the Greater Dallas Metro area.

Quality Service Is Assured With NATE-Certified Technicians

Tuesday 26 May 2015 09:13
Written by

crawford_11_27_12Many homeowners experience uncertainty when hiring HVAC contractors, but one way to eliminate all the guesswork is to entrust the job to a NATE-certified technician. NATE stands for "North American Technician Excellence." While all HVAC professionals are required to carry current and valid state-issued licenses, NATE certification is a purely optional designation. A NATE-certified technician has mastered advanced-level system design, maintenance, installation and repair concepts, and has passed a rigorous series of examinations testing that knowledge.

It's not just consumers who benefit from hiring NATE-certified technicians. Contractors, equipment manufacturers and distributors, and educational and training organizations have implemented the program across the entire HVAC industry to ensure that standardized levels of excellence are easily identifiable and readily available.

Contractors who hire NATE-certified service people benefit from their skill and experience. They usually have lower rates of employee turnover, allowing them to provide consistent service to their valued customers and enjoy higher rates of customer satisfaction.

HVAC equipment installed by these technicians performs better for a longer period of time, with fewer warranty returns and service callbacks.

Finally, because NATE implements uniform standards across the HVAC industry, you can rest assured every time you see the North American Technician Excellence symbol. Certification is very difficult to earn, and only the best technicians and maintenance professionals can achieve it.

We at Crawford Services are proud participants in the North American Technician Excellence program. As part of our commitment to provide homeowners in the Dallas area with the very best products and services, we have NATE-certified technicians on staff who can ensure that your home heating and cooling equipment is correctly installed and optimized for peak efficiency. Not only does this prevent future service callbacks, but also helps to lower your energy costs by providing you with the best possible performance.

If you're experiencing any home comfort issues, or would like to inquire about our comprehensive range of products and services, please don't hesitate to contact us at Crawford Services, Inc. to schedule an appointment.

The Seasons Are Changing So It’s Time To Have Your HVAC System Serviced For The Cold Weather

Tuesday 26 May 2015 09:10

In thcrawford_11_29_12e coming months, you'll be asking your furnace or heat pump to tackle the big job of heating your home and keeping your family warm this winter. That's why it's so important to have your HVAC system serviced by a professional every year. This essential service can protect your heating equipment, and make it's ready to heat your home till spring. An HVAC professional can help your heating system in the following ways: 
    • Perform routine maintenance: Your HVAC equipment is just like your car in the sense that it is a working machine that needs care to keep it running smoothly. When you have your HVAC system serviced, your technician will work on your equipment just like a mechanic performing a tune-up on your vehicle. Moving parts need lubrication to keep working properly, and the functioning of your equipment needs to be checked to ensure everything's working together to do the job.
 
    • Troubleshoot potential problems: When you have your HVAC system serviced by a professional, he can diagnose problems before they lead to expensive repairs. A trained eye can spot problems a homeowner can't; it's always a good idea to have a professional service your equipment before use. Some problems, for example a cracked heat exchanger, are very serious and need attention before further use of your furnace.
 
    • Boost efficiency: Service is not only needed to make sure everything works properly, but to make sure it's working efficiently. Problems such as loose electrical connections could cause your equipment to use excessive energy. Or the inspection might detect inadequate airflow in your HVAC system, or improper refrigerant levels in your heat pump.
 
    • Give you peace of mind: Your technician is available during service to answer any questions you might have. This is a great time to ask about the right air filter or your system or which thermostat settings will boost energy savings this winter. Routine service can also keep your family safe by discovering potentially dangerous malfunctions such as carbon monoxide leaks or fire hazards.

Stay Safe And Ensure Efficiency By Performing Boiler Maintenance

Tuesday 26 May 2015 09:08
Written by

crawford_12_13_12While the Dallas-Fort Worth area doesn't have winters as harsh as points farther north, it's still susceptible to frigid temperatures and bone-chilling winds. One effective method of staying warm during a North Texas winter is a boiler system. However, just like with any sort of HVAC equipment, boiler maintenance is important for smooth and efficient operation.

When undertaking boiler maintenance, a qualified professional will check several things:
  • The chimney and vent connection pipe. A chimney serves to carry the byproducts of combustion out of the building. The vent connection pipe carries exhaust gases from the boiler to the chimney. These should be inspected for leaks, to avoid having hazardous gases such as carbon monoxide escaping into your home and endangering your family.
  • The integrity of the boiler's heat exchanger should be verified. Heat exchangers can allow combustion gases to mix with household air when they have a leak. A leak also allows water to escape the heat exchanger.
  • The controls on the boiler should be adjusted. Adjusting the controls on the boiler will assure comfort and efficiency. This is accomplished by adjusting the air and water temperatures.
  • Safety devices. Blow-off valves, pressure gauges, low cutoff systems and other safety devices should be tested. Some of these safety devices depend on the type of boiler that you have. All safety devices should be checked to ensure proper operation.
  • The boiler should be cleaned. Soot, scale and other buildup can cause a fire hazard and obstruct critical safety systems.
These and other boiler-related steps should always be performed by a qualified professional. For more information about boiler maintenance or other home-comfort or energy-saving issues, please contact us at Crawford Services, Inc.

Home Maintenance Tips Just In Time For Cooler Temperatures

Tuesday 26 May 2015 09:06
Written by

crawford_12_18_12Autumn is a great time to perform home maintenance. Making sure that everything is working as efficiently as it should will benefit your North Texas home especially come winter. Following are home maintenance tips you should follow so you’re ready for the upcoming cold season.
  • Contact an experienced contractor in order to schedule an inspection of your heating system. Gas and oil furnaces should be inspected and cleaned every year, preferably at the beginning of the heating system. Heat pumps generally work best with semi-annual maintenance, once in the fall and another time before the cooling season starts.
  • Check and clean your chimneys for obstructions such as debris, leaves or nests.
  • If your gas furnace has a pilot light, turn it on and turn your thermostat up to heat. You’ll want to test the furnace to make sure it's operating correctly by raising the thermostat until your furnace begins working. Newer furnaces are equipped with automatic ignition, but still need to be tested.
  • Now that you’ll be using your heating system on a regular basis, make sure that you check your furnace filter once a month and change when it gets dirty. Check your ventilation system filters every other month.
  • Make sure that your ductwork is free from any tears or holes. Check the joints to make sure they are sealed tightly. Use mastic sealant or metal tape to seal them.
  • Test your carbon monoxide and smoke alarms, and change their batteries if they run on them.
  • Check your windows to make sure they close tightly, and use caulk or weatherstripping to seal any air leaks.
  • Check your doors and make sure they shut tightly. Use weatherstripping to seal air leaks.
  • Cover up your outside air conditioning condensing unit and turn the power off. It's better to lay a board, or something similar, on top of the outside unit than to cover or wrap it entirely. That will enclose any residual moisture during the winter months, causing rust.
Follow these home maintenance tips this fall so that you'll be ready for winter. To schedule an inspection of your heating system, please contact us at Crawford Services, Inc. We offer the highest-quality HVAC services in the Dallas metro area.

crawford_12_20_12Autumn is a good time to schedule an HVAC maintenance inspection with a local contractor. You don’t want to find out that there’s anything wrong with your heating equipment in the middle of winter. Make sure that you're prepared for your HVAC maintenance inspection by following these tips:
  • There are a few things that you can do yourself before the maintenance visit. This includes checking your thermostat and making sure it has fully charged batteries or power, checking your circuit breakers, and changing your air filters if they're dirty.
  • If you haven't been in your home for very long, make sure you know where your HVAC system components are located. This way you can lead the contractor to your thermostat, circuit box, heat pump and/or furnace without any trouble.
  • Check your HVAC equipment and write down the brand names and model numbers in case the contractor needs them.
  • Write down any problems that you're having, whether one of your rooms doesn’t cool or heat properly, if there’s condensation in your home, or anything else. Try to estimate how long you’ve been having the problem. Writing this down will ensure you don’t forget to mention it.
  • Clear the areas around your HVAC units. Remove any boxes, furniture or other items so the contractor has easy access and doesn’t end up hurting him- or herself trying to reach your equipment.
  • If you cannot make it home in time for the inspection, make sure that someone over the age of 18 is at home during the scheduled appointment time. That person should have all the necessary information.
Follow these simple tips prior to your HVAC maintenance appointment in order to get the most out of your inspection. Contact Crawford Services, Inc. to schedule an appointment today. We provide the greater Dallas area with expert HVAC services as well as superior customer care.

5 Key Ways To Boost The Air Quality In Your Dallas-Fort Worth Home

Tuesday 26 May 2015 09:02
Written by

crawford_12_27_12Dust, dust mites, pollen, chemical vapors and other indoor air pollutants show up in every home, but you don't have to put up with them. Beyond upgrading your HVAC air filters or installing an air cleaner, there are a number of effective, affordable ways to improve the air quality in your Dallas-Fort Worth home.
  1. Maintain good humidity – Dust mites and mold thrive in high humidity. To control these allergens, keep your home's humidity level at around 30 to 50 percent. Given the high summertime humidity levels in Texas, you may benefit from a whole-house dehumidifier. Once installed in your HVAC system, this type of dehumidifier will regulate humidity throughout your home with little need for maintenance.
  2. Schedule a radon test – Radon is a naturally occurring, odorless gas that enters your home through the ground or through well water. This radioactive gas is the second leading cause of lung cancer in the U.S. To find out if your home contains high radon levels, use a radon test kit or hire a qualified contractor to run the test.
  3. Freshen your floors – Place a door mat at every exterior door to trap the dirt, pollen and pesticide residue tracked in on shoes. Use a vacuum with a HEPA filter to pick up remaining contaminants as well as dust mites, pet dander and fire-retardant residue from the carpet. To capture even more debris, mop uncarpeted floors with a microfiber mop.
  4. Skip synthetic scents – The chemicals that lend air fresheners, laundry softeners and similar products their scent could be harmful to your health. For better air quality in your home, switch to fragrance-free or naturally scented products. Avoid aerosol sprays, which may contain harmful chemicals such as formaldehyde, phenols and toluene.
  5. Smoke only outside – Secondhand smoke is laden with harmful chemicals and is the greatest source of indoor air pollution. To keep your home's air clean, step outside to smoke.

Detecting A Life-Threatening Gas Leak In Your Dallas-Fort Worth Home

Tuesday 26 May 2015 09:00
Written by

crawford_1_10_13A properly maintained natural gas furnace is a safe, efficient way to keep your home warm throughout North Texas' chilly winters. On rare occasions, though, even a high-quality furnace can develop problems that lead to a potentially life-threatening gas leak.

Natural gas is highly combustible, so even a minor leak puts you at risk for a fire or explosion. Large amounts of gas can also cause asphyxiation. Just knowing how to detect leaks quickly helps protect you from these unthinkable scenarios.
  • Smell – Because pure natural gas has no odor, suppliers add a non-toxic chemical called mercaptan to give the gas a distinct and easily detectable odor. This chemical contains sulfur, so it smells similar to rotten eggs, sewer odor, onions or boiling cabbage. If you smell this, check that you haven't left a gas valve open on your stove. If you haven't, you may have a leak.
  • Listen – A hissing, blowing or high-pitched whistling sound near any part of your gas system, including an appliance, gas pipes or the gas meter, is a clear sign of a life-threatening gas leak.
  • Look – Gas leaking from indoor pipes or fixtures may blow around dust or other light material. Outdoors, it may cause nearby plants to turn brown and die.
If you think you've detected a leak, put out any open flames or burning material. Don't turn on or off any electronic items or use the phone, which could cause a spark. If you know where your appliance or meter shut-off valves are, consider turning them off with a shut-off tool, a wrench or by hand. Leave the building and contact your gas company immediately.

To keep your gas furnace running safely, schedule professional annual furnace maintenance at the beginning of every heating season. An expert tune-up not only helps prevent gas and carbon monoxide leaks, it also improves your system's energy efficiency, saving you money.

To get more guidance on avoiding a life-threatening gas leak and otherwise staying safe and comfortable with gas furnaces and appliances, contact us at Crawford Services, Inc. We provide top-quality service around the Dallas-Forth Worth area.

Optimizing Air Quality When You’re Remodeling Your Dallas-Fort Worth Kitchen

Tuesday 26 May 2015 08:56
Written by

1_29_13The kitchen is one of the most demanding rooms in your home when it comes to managing air quality. Cooking may produce great meals, but it also produces potentially harmful air contaminants and moisture that could lead to mold and mildew if not dealt with correctly. Remodeling your Dallas-Forth Worth kitchen gives you the perfect opportunity to optimize your cooking area for healthy air.

Choose the right ventilationGood ventilation equipment removes combustion fumes from fuel-burning stoves, excess heat and humidity, and airborne grease and food particles. The most common kitchen ventilation method is a range hood installed over the cooktop. A range hood catches combustion fumes and other contaminants, then vents them outdoors.

To work effectively, the range hood must be large enough and close enough to the stove top. An undersized range hood will let too many contaminants escape. Though some range hoods are designed to sit high over the cooktop, these may be so powerful they pose the risk of back-drafting exhaust gases from other fuel-burning appliances such as the furnace.

Seal air leaks – Blocking air leaks improves energy efficiency anywhere in your home, but it's especially important in the kitchen. Moist air from cooking can seep into gaps and cracks in the walls and ceiling, encouraging mold growth and rot.

Points to seal include gaps around dropped soffits, exhaust fans and penetrations for plumbing, gas and wiring. Sealing dropped soffits is particularly important. Left unsealed, soffits can conduct large amounts of air and encourage condensation. Remodeling your Dallas-Forth Worth kitchen gives you a good opportunity to access the soffits for sealing.

Upgrade your windows – If your windows date back before 1978, they may contain hazardous lead-based paint. These windows should be replaced. Even if your windows are free from lead paint, replacing single-paned windows with Energy Star-qualified windows helps reduce drafts, prevent condensation and discourages mold growth, as well as improving your kitchen's energy efficiency.

For more pro tips on remodeling your Dallas-Forth Worth kitchen, contact us at Crawford Services, Inc. We provide reliable, cost-effective HVAC services throughout the area.

Contact Your HVAC Service Before Adding On To Your Dallas-Forth Worth Home

Tuesday 26 May 2015 08:54
Written by

1_31_13Before building an addition onto your Dallas-Fort Worth home, contact your HVAC service provider and consider these three options.
  • Extend your current system – If your system has a large enough capacity to condition the additional space, you may only need to extend the ductwork and install registers. For a zoned system, you may also want to add dampers to make the addition a separate zone. Sizing a furnace and air conditioning system is tricky, so talk with a HVAC service provider before extending your system to make sure the job will meet the local city and municipality codes.
  • Upgrade your system – If extending your HVAC system isn't possible or practical, use your construction project as an opportunity to install a new, more efficient HVAC comfort system. Today's systems are up to 40 percent more energy efficient than those made even 10 years ago. Just as important, you'll be able to choose a system sized to handle your whole Dallas-Fort Worth home, including the new addition.
  • Install ductless mini splits – This system consists of an outdoor condenser unit and one or more indoor air handlers that distribute air. Installation is simple because there's no need for ducts or complicated wiring. The system requires only a small space and minimal disruption in your home. Mini split systems save energy because there's no ductwork to leak conditioned air and they are usually rated up to 30 SEER (Seasonal Energy Efficiency Rating). As another benefit, mini splits will let you control the temperature in your addition independently from the rest of your house.
Other options for a separate system include a high-velocity mini duct system or radiant floor heating. Radiant systems are more expensive to install than forced air systems, but they're also up to 30 percent more efficient.

To make sure you choose the most cost-effective heating and cooling system for your Dallas-Fort Worth home addition, it's wise to start planning early. For professional guidance on the best option for your needs, contact your HVAC Service, Crawford Services, Inc.

Calling Your Dallas HVAC Service? Insist On NATE Certification

Tuesday 26 May 2015 08:51
Written by

2_7_13HVAC service is a complex field that requires an understanding of multiple types of heating and cooling systems as well as electrical and mechanical systems. All licensed Dallas HVAC service technicians have training in these topics, but not all are trained to the same level. Seeking NATE certification is the best way to find highly trained HVAC technicians.

North American Technician Excellence (NATE) is a nationally recognized third-party certification program. Technicians take rigorous exams on core competencies and can also take specialty exams for certification in topics like air conditioning, air-source (standard) heat pumps, and gas furnaces.

The program is voluntary, so you know certified Dallas HVAC service technicians are deeply invested in their careers and take exceptional pride in their work.

When you work with NATE-certified technicians, you can expect:
  • Reliable results – Technicians who hold NATE certification get the job done right the first time. A 2006 study conducted by Service Roundtable found these technicians receive 12.9 percent fewer callbacks and fewer warranty returns than other technicians.
  • Efficient service – NATE-certified technicians are often better able to identify the root cause of your HVAC problems. This lets them start their work faster, meaning less waiting and lower bills for you.
  • Increased energy efficiency – Incorrect equipment sizing, improper installation and inadequate maintenance reduce your system's energy efficiency. Dallas HVAC service technicians who hold NATE certification are well versed in the correct procedures for optimizing HVAC system efficiency. Working with these technicians, you'll enjoy lower energy bills and equipment that performs optimally for years.
  • Expert advice – Service Roundtable found NATE-certified technicians hold an average of 25.9 percent more experience than other technicians. Broader experience better enables them to provide you with accurate information based on your needs and budget.
Not surprisingly, these benefits lead to greater customer satisfaction. A NATE poll found customers who worked with NATE-qualified technicians were 24 percent more likely to feel "extremely satisfied" than people who worked with other technicians.

For professional guidance on choosing and maintaining HVAC equipment to keep your home comfortable affordably, contact us at Crawford Services. Our highly qualified Dallas HVAC service technicians provide service throughout the Dallas-Fort Worth area.

Before Calling Your Dallas Plumber, Troubleshoot Your Water Heater

Tuesday 26 May 2015 08:48
Written by

02_14_13Searching for a Dallas plumber? When your water heater stops working effectively, you can be justifiably eager to get the system functioning again at its best level. Before turning to your local trusted Dallas plumber, try a few of the following troubleshooting tips to see if they help get the hot water flowing like you expect.
  • Check the area: If your water heater is in an area of your home that is not heated, it will not be able to heat water as efficiently as it would if it was placed in a conditioned area. Even just blocking drafts and cold air leaks will improve the heater's performance. Check the area around the water heater and seal leaks, caulk windows or stop cold air drafts.
  • Insulate the pipes: As hot water travels from the heater to your kitchen, bathrooms, basement or other areas, the water inside the pipes can lose a lot of heat energy and cool off. To prevent excess cooling in the pipes, insulate them wherever you can reach them. Ask your Dallas plumber about pre-made insulating sheaths; usually, these can be found at your hardware or HVAC supply store. If that doesn't work, wrap the pipes in standard fiberglass roll insulation.
  • Insulate the water heater itself: Storage-type water heaters can experience standby heat loss as water sits in the storage tank before being used. You can reduce this wasteful loss by insulating the water heater itself. Pre-made blankets, which are custom-shaped insulation coverings for a water heater, should be available through your hardware store or HVAC supplier.
  • Check the dip tube: Make sure the dip tube, the pipe that runs from the cold water supply to the bottom of the tank, is not damaged, broken or cracked. If the dip tube is damaged, it could be letting cold water mingle with and cool the hot water inside the heater. Call a licensed plumber to evaluate the dip tube for you and ask him or her to show you the existing tube so you can determine if this is the problem. it is a simple fix and can save you alot of money on future repairs and the costs to heat your water.
Customers in Dallas and the surrounding North Texas communities can turn to Crawford Services, Inc. for reliable, professional heating, air conditioning, and plumbing services.

Hiring Dallas HVAC Contractors: 10 Tips To Consider

Tuesday 26 May 2015 08:46
Written by

03_27_13Finding quality Dallas HVAC contractors to service and repair your heating and cooling systems can be a much easier task if you follow these 10 evaluation and hiring tips:
  • Check licensing and qualifications. Contact the Texas HVAC licensing board to make sure the contractor you're considering is licensed and meets all other state and local requirements.
  • Check references. Ask for contact information for past customers and ask at least three of them about their experiences with the contractor.
  • Use your resources. Go to trusted friends, relatives or coworkers and ask about Dallas HVAC contractors they've used and would recommend.
  • Ask for an in-person evaluation. Request that the contractor visit your project site for an in-person evaluation before offering bids or estimates. Ask to see pictures of his installation practices and get references from other installations.
  • Get written bids and itemized estimates. Ask at least three contractors to provide formal bids and estimates. Willingness to submit an official bid indicates interest and can help reduce the costs of your project.
  • Sign a contract. Execute a written contract that lays out the scope of the project and any contingencies. Make sure you understand it thoroughly before signing. Do not proceed until you and the contractor have both signed the contract.
  • Understand payment terms. Be sure you know if any payments are required in advance and when the final payment is due.
  • Insist on energy efficiency. Hire a contractor who uses Energy Star products and who adheres to industry standards for energy efficiency in design and construction.
  • Ask about discounts or special offers. See if your contractor offers any pricing incentives. Remember that the federal government provides income tax credits for certain types of HVAC equipment. There also may be state or local incentives you can use to reduce your costs.
  • Request that the contractor get any necessary permits. He will be more familiar with the process and likely will be able to get them more quickly and easily.

Boiler Repair: When Troubleshooting Fails, You Need A Dallas HVAC Professional

Tuesday 26 May 2015 08:43
Written by

04_04_13When boiler repair becomes necessary in your Dallas home, your best option is to call your local trusted HVAC service provider for expert repair. Boilers are volatile and potentially dangerous pieces of heating equipment that should be worked on by trained and certified experts in boiler repair and operation.

There are a few simple troubleshooting tasks you can perform on your own, such as:
  • Checking circuit breakers and resetting any that have tripped.
  • Checking for and replacing blown fuses.
  • Ensuring the pilot light is on (if the unit has a standing pilot).
  • Making sure thermostat is set to heat mode.
  • Ensuring the thermostat's temperature setting is appropriate.
Other, more involved troubleshooting and boiler repair tasks should be left to your HVAC specialist. The technician will check the system's operation and perform repairs such as:
  • Check and adjust water level and water pressure in the boiler.
  • Check the ignition system (if appropriate) for proper operation and repair or replace defective ones.
  • Check and calibrate thermostat for proper control and operation of boiler. Replace thermostat as needed.
  • Make sure boiler is receiving fuel and that there are no dangerous fuel leaks or other problems associated with fuel transport.
  • Flush the boiler to remove accumulated sediments or mineral deposits that might be affecting performance.
  • Check expansion tank for proper amount of water and appropriate pressure.
  • Check for leaks around the pressure relief valve and various pipe connections. Repair leaks as needed.
  • Test pressure relief valve performance and repair or replace if necessary. The pressure relief valve is a critical component that prevents overpressurization and potential breakdowns and hazardous conditions near the boiler. Make sure this valve is operating correctly.
  • Bleed air from radiators to restore heating function.
  • Make sure water circulator is running properly and distributing hot water as needed to radiators. Repair or replace circulator as needed.
  • Adjust pitch of return lines to make sure no water is trapped in these pipes.
In the Dallas area, Crawford Services, Inc. is a leading provider of professional heating and cooling sales, maintenance and repair. Contact us today for more information on boiler repair and troubleshooting, and for the repair services you need to keep your boiler working efficiently, reliably and safely.

Heat Pumps Operate Most Efficiently With Proper Maintenance, So Hire an HVAC Pro

Tuesday 26 May 2015 08:42
Written by

05_23_13Heat pumps offer reliable, straightforward performance along with high efficiency and long service life. Maintenance requirements are not extensive; however, the importance of maintenance is more critical with a heat pump than with conventional forced-air systems. Lack of regular maintenance alone can cause the efficiency of heat pumps to decline as much as 25 percent, nearly offsetting all the efficiency gains provided by the technology. While some simple tasks may be performed by the homeowner, the technical requirements of heat pumps generally require a trained HVAC technician with specialized tools. Here’s what he or she will do in about an hour:
  • Examine the air filter and replace it if required. For maximum performance and efficiency, heat pumps require higher airflow than conventional HVAC systems so a clean filter is critical. Inspecting the filter (and changing it if necessary) is one thing you can and should do yourself on a monthly basis. If you don’t know how, the technician will be happy to show you.
  • Duct inspection for external signs or leakage at seams and joints and internal accumulation of dust or dirt. Evidence of leakage may suggest pressure testing to determine the severity and location of leaks system-wide.
  • Verify the refrigerant charge. Low refrigerant almost always means a leak somewhere. Your technician has the equipment to detect and locate leakage.
  • Inspect electrical connections and clean and tighten if necessary.
  • Test the controls that disable the heating function when the thermostat is set for air conditioning and vice versa.
  • Compare thermostat room temperature with a reading from a mercury thermometer and calibrate the thermostat if necessary.
  • Outside, clear any vegetation such as weeds and shrubbery away from the vent grilles of the outdoor coil and fan component. Keeping grass, brush and weed growth cut back year-round is another DIY task you can perform.
  • Clean the outdoor coil of dust and vacuum debris such as grass clippings and leaves from the coil cabinet. Lubricate the fan and check the tightness and wear of the fan belt.

A Dallas Plumber Will Suggest Low Flow-Toilets for Maximum Savings

Tuesday 26 May 2015 08:39
Written by

Ask a Dallas plumber and he'll tell you that low-flow toilets now offer superior performance to the old-school, water-wasting models they replace. This wasn’t always the case: Early low-flow units introduced in the 1990s under-performed, and customer satisfaction suffered. Today’s low-flow toilets meet stringent federal EPA requirements for efficiency, and conserve water while also providing improved operation over standard models. Toilets are overwhelmingly the largest single user of water in the average household, representing about 30 percent of the home’s total water consumption. Here are some guidelines when thinking about having a Dallas plumber install low-flow toilets in your bathroom renovation project:

Look for labels that specifically identify models as high efficiency toilets (HETs). These models, which use 1.30 gallons per flush (gpf) or less, conserve the most water and deliver the greatest savings. To make sure you’re getting the greatest efficiency along with superior performance, a Dallas plumber will usually recommend one with the EPA’s "WaterSense" label. These toilets meet HET standards plus have passed a third-party certification process to verify performance. Over its average service life, a residential toilet will be flushed 140,000 times. Upgrading standard 3.5 gpf toilets with HET models can save 4,000 gallons per year.

Don’t be distracted by high-priced options or aesthetics. Stay focused on specifications that guarantee water efficiency and performance. Paying a higher price for a more aesthetic design or color scheme may not deliver higher efficiency.

Try out a number of toilets with different heights, seat types and rim conformations. Round and elongated bowls are commonly available, but take measurements in your bathroom before you shop to make sure an elongated model can fit in the existing space without alterations.

In North Texas, Crawford Services sets and fulfills high expectations for air conditioning, heating and plumbing services. Call and schedule a Dallas plumber to install a water-saving high-efficiency toilet for your home.

Looking for Heating and Air Conditioning Experts in Dallas? Require NATE Certification

Tuesday 26 May 2015 08:38
Written by

06_04_13Heating and air conditioning Dallas weather certainly poses challenges for controlling indoor temperatures. Our sweltering summers and chilly winters place demands on your HVAC system year round. In your effort to stay comfortable, North American Technician Excellence (NATE) certified technicians are your greatest allies.

North American Technician Excellence Inc. is a nonprofit organization that provides comprehensive, high-level training and testing for heating, ventilation, air conditioning and refrigeration technicians.

HVAC training courses and state licensing require only a minimum level of knowledge and skill. That means even after studying heating and air conditioning Dallas technicians without further training may not be able to handle anything but the most basic HVAC issues.

NATE certification sets the experts apart from the novices. Known for its rigorous standards, NATE trains and tests HVAC professionals in basic concepts and technology as well as in the newest innovations. To retain certification, technicians retest every five years.

  • Gas furnaces
  • Oil furnaces
  • Air-to-air (conventional) heat pumps
  • Ground-source heat pump loop installation
  • Air distribution
  • HVAC efficiency analysis
Working with NATE-certified technicians has proven benefits. Service Roundtable's NATE Impact Study found several areas in which these technician outperform their non-NATE peers:
  • Less hassle – NATE technicians get the job done right the first time, saving you time and money. Their callback rate is 12.9 percent lower than non-NATE technicians.
  • Lower energy bills – NATE technicians know the installation and maintenance procedures necessary for your system to reach maximum efficiency. Given the high bills for heating and air conditioning Dallas weather can leave us with, optimal energy efficiency is a major benefit.
  • Friendly, reliable service – When technicians have invested in earning NATE certification, you can be sure they take their job seriously. They'll arrive on time, work efficiently and clean up afterward. NATE-certified professionals achieve a higher rate of "extremely satisfied" customers than do non-certified technicians.
If you want the peace of mind working with a NATE-certified technician brings, please contact us at Crawford Services. Our highly skilled technicians provide reliable installation and maintenance in Dallas and nearby areas of North Texas.

HVAC Dallas TX Power Needs Are Year-Round — Consider Standby Generators for Your Security

Tuesday 26 May 2015 08:35
Written by

In terms of HVAC Dallas TX presents challenges year round. North Texas' icy winters, torrid summers and spring thunderstorms mean you need a heating and cooling system you can rely on. By installing a standby generator, you can rest assured that your cooling and heating system will work consistently even during long power outages.

Portable versus standby generators

A portable generator can power only a few basic items. Its fuel supply is limited, so it needs to be monitored and refilled regularly. You'll need to set it up when the power goes out and put it away when the power returns. The manual fueling can be messy as well.

Standby generators, on the other hand, keep you in comfort with no extra effort on your part. These generators are permanently installed outside your home and connected to your home's electrical system. Depending on the size, a standby generator can power just a few appliances or your entire home. In terms of your HVAC Dallas TX can throw any sort of weather at you, and you'll still get reliable emergency power with a standby generator.

A standby generator senses when your utility company's power goes out, automatically disconnects you from your utility company, then starts supplying electricity to your home. When the power returns, the generator senses this, automatically shuts down, and transfers you back to your utility company. These generators can run for days because they're connected to an external fuel supply, such as natural gas lines or your home's propane tank.

Standby generator benefits

With a standby generator powering your HVAC Dallas TX weather will never leave you sitting around sweating in summer or shivering on a winter night because the power's out. Your health is protected, too. You'll avoid air conditioning outages and the sudden exposure to high temperatures that can cause heat stroke in people of any age.

If you rely on a sump pump to prevent storm-related basement flooding, a standby generator will keep your pump running even if a storm knocks the power out.

With HVAC Dallas TX is no place to take chances. If you're considering a standby generator to maintain consistent comfort and safety in your home, get in touch with us at Crawford Services. We provide value-driven HVAC solutions in the Dallas area.

Searching for an A/C Contractor for Your Dallas Home: Some Tips to Help You

Tuesday 26 May 2015 08:33
Written by

08_06_13Finding an A/C contractor in the crowded and competitive HVAC field can seem like a major challenge. Here are some reliable tips you can use to help you choose the best A/C contractor for your job.
  • Start with who you know: If you're already using an HVAC contractor for other projects, start there. It's very likely your existing contractor also does air conditioning work or will be able to recommend a business partner or other contractor who can do your A/C job.
  • Ask around: Ask your friends, co-workers, family members and business colleagues for information about contractors they've used. If they were happy with the contractor's services, chances are good you will be, too.
  • Check industry resources: Many industry groups and trade organizations provide directories of HVAC contractors who are members of the group. The main trade association for air conditioning is the Air Conditioning Contractors of America (ACCA). Membership in a trade organization is a sign that a contractor is interested and involved in his industry, so contractors in these organizations are likely to be a cut above the rest.
  • Use the bidding process: Request written bids for your project from at least three different contractors. If a contractor is willing to go through the bidding process, it shows he is genuinely interested in your project and understands the procedures required to get work. The bid should contain details on the scope of the job, equipment, supplies and costs. A written bid will confirm that both you and the contractor know what's to be done and will help constrain the costs of the project.
  • Make sure your contractor is involved: Use an A/C contractor who becomes involved in your project from the earliest possible stages. Your contractor should evaluate your project in person to assess all the factors that must be accounted for during the job. He should conduct a cooling load evaluation to calculate how much cooling your home or business location needs. He should be able to show you the results of these calculations and be able to choose an A/C system that is properly sized to provide the amount of cooling required.
  • Ask about high-efficiency equipment: An A/C contractor who is up to date on the HVAC industry should have a good understanding of high-efficiency equipment, and should be able to recommend which types of A/C systems will work best for you.
The dedicated professionals at Crawford Services, Inc. work hard to make sure their customers receive the best possible HVAC installation, maintenance and repair services. Contact us today for more information on choosing an A/C contractor for your project. We'll be happy to provide the answers you need to make an informed hiring decision.

Condensate Drain Maintenance Can Help Save Time and Hassles

Tuesday 26 May 2015 08:30

A condensate drain is responsible for eliminating moisture from your compressed air system. And,your air conditioning unit can create a lot of condensation, especially when it is hot and humid outside. Essentially, condensate drains are responsible for taking the water from your air conditioning unit and sending it outside. If your condensate drain is not properly installed or functioning correctly, it can wreak havoc on your air conditioning unit. A condensate drain that is properly installed and maintained can save you from headaches and inconvenient issues down the line, and more importantly, the drain can save you money through operating costs and improved energy use.

It is of the utmost importance that a condensate drain be kept clean. Unfortunately, if your condensate drain is not cleaned regularly, algae can form in the drain, which can clog the line and damage your entire system. Also, when the system is not in use, insect, dust and pollen can collect in the drain, which can cause damage over time.

If your condensate drain needs to be cleaned, there are a couple simple steps you can take that can make a difference. A condensate drain can be snaked, just like the drain in your shower or sink. However, it is possible for what looks like a simple condensate drain cleaning to turn into a more complicated issue that is better suited for a professional. For example, weak or leaking pipes or a tough clog can create lots of damage to your system if not handled properly. So, if you check your condensate drain and notice something abnormal, it is best to hire a professional who can provide you with exceptional service and peace of mind.

basinger-before-1Condensate drains function best when they are checked annually at a minimum. It is an even better idea to check or have your condensate drain checked seasonally. Also, many service professionals offer maintenance agreements that give you more value for your money. In addition to making sure your drain is functioning properly, a service professional can check other parts of your system to ensure everything is functioning the way it should be.

There are many types of condensate drains, so finding the best one for your system is crucial. If there are any doubts about the type of condensate drain you should purchase, allow a professional to step in to help make recommendations.

Condensate drains are an important part of your compressed air system, and even though it may be easy to forget about maintenance for your condensate drain, it is crucial that the drain is checked regularly for leaks and clogs. If working efficiently and correctly maintained, condensate drains save you money in energy costs and in hassles. Performing a simple check of your condensate drain is something anyone can do, but for a full checkup, consult with a professional.

Keeping Air Filters Clean and Other End of Summer Cooling Tips to Maximize Efficiency

Tuesday 26 May 2015 08:27
Written by

09_05_13Air filters are essential to the efficiency of your air conditioner. Your system has worked all summer long to keep you cool in the North Texas heat, and as summer winds down, it's important to continue checking your air filter every month and replacing it when it's dirty. Clean air filters are your first defense against inefficiency, ensuring optimum airflow and protecting your system against dust. These additional tips will help you maximize your system's cooling power to keep you comfortable until cooler weather arrives.

Maintain Your A/C
  • If you didn't schedule a tune-up at the beginning of the summer, it's not too late to benefit from preventive maintenance, which will lower your cooling bills, increase system efficiency, extend the life of your equipment, and prevent common air conditioning problems.
  • Spray down your outdoor unit each month to remove debris from the metal fins, which can inhibit heat exchange and make your system work harder to keep you cool.
  • Stock up on air filters so you have them when you need them.
Keep the Heat Out
  • Close your window shades during the day to prevent heat gain from warming up your rooms.
  • Avoid using heat-generating appliances during the hottest part of the day.
  • Seal air leaks around windows and doors with caulk and weatherstripping to keep cool air in and warm air out.
Maximize A/C Cooling Power
  • Keep obstructions away from your return and supply ducts to maintain optimum airflow and replace dirty air filters each month.
  • Seal your ducts with mastic sealant or metal tape to prevent cold air from escaping through loose joints. The typical home loses 20 to 40 percent of conditioned air through leaky ducts.
  • Use your ceiling and room fans to help you feel cooler. Turn them off when you leave the room to save on electricity costs.
  • Keep your thermostat at the highest comfortable temperature to ease the load on your system.

A Fall Maintenance Checklist to Keep Your Dallas Area Home and HVAC System in Shape

Tuesday 26 May 2015 08:16
Written by

09_25_13Any responsible Dallas HVAC contractor worth his or her weight in refrigerant will suggest making a fall maintenance checklist to ensure all systems are operating efficiently and safely, especially combustion furnaces and appliances. Do you have your list ready? If not, use ours.

Home Safety

The safety of you and your loved ones is important during any season. Follow these steps for keeping your home safer during fall or any season:
  • Check the batteries in smoke detectors. If you have combustion appliances, a furnace, fireplace or wood stove, you should also make sure you have carbon monoxide (CO) detectors installed and in working order.
  • Attached garages should be sealed off from the living spaces. Install weatherstripping around the access door, and caulk any holes you see in walls and the ceiling. Attached garages are common sources for CO infiltration.
  • Seal cracks in walkways and the driveway.
Home Comfort and Efficiency

Take specific measures to make your home more comfortable and efficient for the forthcoming cooler weather.
  • Inspect weatherstripping around entry doors, and install as needed to seal air leakage.
  • Caulk cracks and gaps around windows.
  • Check exterior pipes, electrical wiring and cables for gaps and cracks that need caulking.
  • Boost attic insulation.
Fall HVAC Checklist

Schedule fall preventive maintenance with your Dallas HVAC contractor to ensure safe and efficient performance of your furnace or heat pump. These are just a few of the checks he will perform:Furnace
  • Check for gas leaks
  • Check the ignition system
  • Check and clean burners
  • Check heat exchanger for cracks
  • Check the flue or chimney for proper draft
Heat pump
  • Check reversing valve
  • Check defrost board
  • Check heat sequencers
  • Check for airflow restrictions (supply outlets, return grilles and outside cabinet)
  • Clean or change the filter (heat pump and furnace)
If you use a whole-house dehumidifier during the cooling months and/or a whole-house humidifier during the heating months, your Dallas HVAC pro can help you clean, inspect and prepare these systems for summer's end and the arrival of fall.

For more fall maintenance tips for your North Texas home, contact a reputable Dallas HVAC contractor by calling Crawford Services, Inc. today.

HVAC Service: Know What Your Home Needs to Stay Healthy Through The Winter

Tuesday 26 May 2015 08:12
Written by

HVAC Service is vital to keeping your home warm and cozy during the winter months, as well as cool and comfortable during the summer months. The extreme temperatures of winter and summer can wreak havoc with your cooling and heating equipment. But, a regular HVAC service can save money over the long term as HVAC repair and replacement can be one of the highest expenses a homeowner has to face. Preventative maintenance can help to save on costly repairs that tend to occur at the most inopportune moments.

06_20_13

What Should the HVAC Service Include?

After calling in a professional to complete your HVAC service, he or she should examine the following parts of your system:

• Thoroughly clean and check over the condenser coils, straightening them out if necessary. This will ensure a proper flow of air in the system.

• Check all gas connections, in case of leaks.

• Check all refrigerant levels, in case of leaks.

• Tighten up all electrical connections.

• Check all lubricant to the moving parts within the system.

• Check that the thermostat is functioning correctly – switching off and on according to the settings.

• Check and clean the air filter.

An annual inspection and HVAC service is imperative to ensure the smooth running of the system so that everything performs at maximum efficiency. This will also help to extend the useful life of the equipment. An annual check-up may even save you money in more ways than one:

1. Reducing your property energy bills – efficient, well serviced equipment is much more cost effective than badly performing equipment in need of service.

2. Reducing the likelihood that your heating equipment will simply go “bang” and need costly replacement or repairs.

Arranging a regular HVAC service with a recognized, professional company can help you to save money and give you real peace of mind. Many service contractors will offer contracts for an annual HVAC service to include a spring visit to check out and service the air conditioning unit and a pre-winter visit to check over the heating system ensuring maximum efficiency during the colder months. Signing one of these agreements could also mean that you can receive discounts over any needed repairs or purchasing new equipment.

In conclusion – don’t try to skimp on HVAC service costs. That’s almost a guarantee that repairs will end up costing you more in the long run. You may think that paying for the service is a waste of money which could be better used elsewhere . . . but, think again. Having a regular HVAC service can help to save money on your heating bills and prevent the incredibly expensive option of needing to repair or replace the entire unit.

Preventative Spring Service for Your AC Now Can Help to Negate Problems Later

Tuesday 26 May 2015 02:14
Written by

Spring service of your AC unit is probably the last thing on your mind in the cold, dark days of winter – it’s all about keeping warm isn’t it? Those hot summer days seem to be so very far away when you’re all huddled up inside with lots of layers of clothes and scared to leave the house without gloves, scarf and a woolly hat.

03_07_13The problem is that March is already upon us and the way the seasons fly by it’ll be April, May and June before we even get a chance to pack away our winter sweaters and find our shorts and flip-flops.

The reality is that a preventative spring service on your AC unit is something which you ought to seriously consider so that you can prevent any problems later in the year. And, you need to do it now to make sure that when the temperatures do start to rise, your home will be ready for it.

What happens in the Spring? The birds start to sing, the trees begin to get their leaves and the spring flowers begin to blossom – which leads to dust, pollen and allergens all swirling around outside your home – yep, spring is definitely the season of allergies.

If your AC unit is serviced before allergy season takes hold, you can be sure that the evaporator coils are dust free, clean and ready for action – allowing them to deal with anything that gets blown inside. This means that a spring service on your AC unit will help to keep your home cool, clean, healthy and allergen free.

There are of course other reasons why your AC unit should be regularly serviced –and a spring service is the perfect time for the annual check-up.

• A well serviced and maintained AC unit will work more efficiently, which means that not only will your home maintain a comfortable temperature all over, but it will do so without using up too much valuable electricity. A well maintained AC is much more “pocket friendly” than AC units which are not running at full efficiency.

• A well serviced and maintained AC unit will last longer than one which has been left to struggle, smoke, wheeze and clatter along. Regular servicing means that any worn out parts can be serviced or replaced before they start to affect the other parts of the unit. It’s notcheap to replace an AC unit, it’s much more cost effective to look after the one you’ve got and have it regularly serviced.

Those long hot summer days are really not too far away – make sure that your home is fully prepared with a spring service on your AC.

With A Whole House Humidifier, You’ll Breathe Easier And Feel Better

Tuesday 26 May 2015 01:55
Written by

Indoor air that's too dry is uncomfortable, unhealthy, promotes static-electricity, and may damage wooden items and furniture in your home. A whole house humidifier works to alleviate these issues, and it can help lower utility costs, too. If any of the following situations pertain to your household, you may benefit from a whole house humidifier:
    • Loved ones who suffer from seasonal or daily allergies or respiratory issues.
    • Family members who feel fatigued, under the weather, or not quite 100 percent when indoor air is dry.
    • Occupants of hour home experience excessive static electricity shocks.
How whole house humidifiers work

A whole house humidifier (WHH) attaches to your furnace. As the blower circulates air through the ductwork, the WHH adds the optimal amount of moisture, ensuring that your entire home receives comfortable humidified air. Powered WHHs are available with their own blower, as well, eliminating dependency upon the furnace blower. A WHH doesn’t require water refilling (it’s plumbed to your home’s water line), and you only need to change the filter twice a year.Better heath, comfort and savings

Implement a WHH into your home-comfort strategy, and receive the following benefits:
    • Properly humidified air inhibits the growth of many viruses and bacteria, and reduces the spread of dust. This provides relief to loved ones who suffer from allergies and respiratory issues such as asthma.
    • Virtually eliminates annoying static-electricity shocks. A WHH covers all surfaces in your home with a thin layer of water molecules. This prevents the buildup of electrical charges. Static-electricity shocks can damage sensitive electronics, such as computers, cameras and phones. It can awaken or disturb young children, babies and pets.
    • Dry air feels colder than properly humidified air at the same temperature. By maintaining optimal humidity levels, you may lower the thermostat on heating days, and save about 10 percent or more on utility costs.
    • Indoor air that's properly humidified prevents dry-air damage to wood furnishings, cabinetry, hardwood floors and musical instruments. Dry air may also damage sentimental photos, important files and artwork.

Selecting A Standby Emergency Power Generator? How To Choose the Right One For Your Home

Tuesday 26 May 2015 01:46
Written by



crawford_12_11_12Our lives are more dependent on electricity than ever before. Yet, electrical blackouts are also becoming more and more common, affecting about 3.5 million Americans in an average week. Most of those power outages are caused by the weather, either through storms or extreme temperatures that place too much strain on the electrical grid.

Because of this, standby emergency power generators are growing in popularity. A standby emergency power generator can turn the power back on in mere seconds, providing the electricity you need to light your home, keep your HVAC system running and keep your refrigerated food from spoiling. And it does so automatically, without you having to venture out into the storm or stumble through a dark house.

There are multiple standby emergency power generators on the market. Choosing the right one for your North Texas home requires looking at your overall electrical needs, as well as your own budget and personal preferences.

Electrical load

The first step is to determine how much electricity your house consumes. Major appliances, such as your HVAC system, should have energy labels that indicate how much electricity they consume. For lights, you will need to add up the wattage of all the light bulbs being used. Of course, for an easier and more accurate measurement of electrical load, you can consult a licensed electrician.

Generator options

You then have to decide whether you want a standby emergency power generator that is large enough to cover your entire electrical load, or one that will focus only on essential parts of the house.
  • A whole-house generator will run every electrical device in your house at the same time.
  • An essential circuit generator only powers the most important circuits in your house, such as the HVAC system or fridge. It is smaller and cheaper than a whole-house unit.
  • A smart circuit generator also only powers certain circuits, but it can switch between circuits depending on where the need is greatest.
For help in choosing the right generator for your Dallas-Fort Worth home, please contact us at Crawford Services, Inc. We would be happy to answer your questions.

Shopping For HVAC Equipment In A Dallas-Fort Worth? Look For The Energy Star Most Efficient Label

Tuesday 26 May 2015 01:43
Written by

1_15_13If you've been shopping for HVAC equipment recently, you may have noticed how many products carry the Energy Star label. While it's good to know Dallas-Fort Worth has plenty of energy-efficient products available, the abundance can make it hard to tell which products are truly the best of the best.

To help you find highly efficient products, federal Energy Star program experts have introduced the Energy Star Most Efficient program. To qualify for Most Efficient status, a product must meet criteria that place it in the top 5 percent of energy-efficient products in its class. For heating and cooling systems that qualify, these are some of the ratings you can expect:
  • Air conditioners – Most Efficient packaged A/C systems, which require ducts and vents, must have a SEER (seasonal energy efficiency ratio) of at least 16 and an EER (energy efficiency ratio) of 12 or higher. Ductless mini split A/Cs, which use indoor air handler units mounted on walls or ceilings, must have a minimum SEER of 18 and EER of 12.5.
  • Furnaces – A gas furnace with Most Efficient status must have an AFUE (annual fuel utilization efficiency) of 97 percent or higher. If you can't find a Most Efficient furnace while shopping for HVAC equipment, for high efficiency look for one that has an AFUE of at least 90 percent.
  • Air source heat pumps – Packaged heat pump systems must have a minimum SEER of 16, EER of 12, and HSPF (heating seasonal performance factor) of 8. A split heat pump system must have a SEER of 18, EER of 12.5, and HSPF of 9.6 or higher.
  • Geothermal heat pumps – A closed-loop water-to-water geothermal heat pump (for a forced-air system) must achieve an EER of 16.1 and COP (coefficient of performance) of 3.1 or greater. A closed-loop water-to-air geothermal heat pump (for a hydronic radiant system) must have an EER of 17.1 and a COP of 3.6.
For expert help shopping for HVAC equipment and choosing the right energy-efficient system for your home, please contact us at Crawford Services. We provide HVAC services that residents of the Dallas-Fort Worth area have come to rely on.

Heat Pump Operation: Keep it Efficient and Avoid Heating Repair in Dallas

Tuesday 26 May 2015 01:41
Written by

02_19_13A heat pump that isn't working properly can be a major frustration. If your heat pump is giving you problems, try a few of the following troubleshooting tips to see if you can get the unit working again.

Heating or cooling incorrectly:
  • Make sure the thermostat is set to an appropriate temperature. If it's set too low in winter, for example, it won't start the unit to provide heating.
  • Check the settings to ensure the system is set to provide heating or cooling, as appropriate.
  • Check the air filters to see if they are dirty or clogged. Dirty filters block airflow and can cause heat pump malfunctions. Replace any dirty filters. We suggest that this be done at a minimum of 4-6 times annually depending on the filter type, age of the equipment and amount of exposure the home has to outside contaminants and dirt.
Unit is cycling incorrectly:

Make sure the thermostat is working properly and is mounted in a spot where it can take accurate temperature measurements. If your thermostat is placed where sunlight can shine directly on it, for example, it will return temperature readings that are higher than the actual temperature of the room. Conversely, if the thermostat is in a closet or away from the main traffic areas, it may not read the correct temperature readings in the main living areas of the home.

No air is coming out:
  • Check the registers and make sure dampers have not been closed and that no objects are blocking the registers.
  • See if the blower fan is working. A damaged or broken blower belt could be the problem. Replace the belt according to manufacturer's instructions.
  • Check to make sure the filters are not clogged or dirty.
Unit doesn't work:
  • Check power connections and make sure the air conditioner or heat pump is switched on and receiving power.
  • See if any of the circuit breakers on the unit or at the main breaker panel have tripped. Reset them and try to start the unit again. Check any fuses and replace any that have burned out.
  • Check for a reset button on the outdoor unit and press it to see if that restores operation.
  • Make sure the condenser coils in the outdoor unit are free of ice or other material that could block airflow. If the coil is iced over, turn the unit off and defrost with an electric hair dryer or leave it off until it defrosts naturally. Then call your HVAC service provider immediately. The coil leak may be an easy fix if you catch it in time.
Contact the experts at Crawford Services, Inc. for professional HVAC services, such as cooling and heating repair, that Dallas homeowners can count on. We can help you with information on air conditioners and heat pump troubleshooting and with the regularly scheduled maintenance and repair you need to keep your home comfort system working properly.

Need HVAC Equipment? Thinking of Buying Online? Three Risks To Consider

Tuesday 26 May 2015 01:07
Written by

If you need HVAC equipment, you may be tempted to buy through an online retailer to save a little bit of money up front. Online vendors have lower overhead costs, allowing them to offer you brand-name furnaces, boilers, water heaters, heat pumps and air conditioners at reduced prices. However, these savings come with significant risks – risks that could end up costing you a lot of money in the end. You should take these potential problems into careful consideration and deal with a licensed professional contractor in your area rather than buying the equipment from an online retailer .

Considering HVAC Upgrades For Your Dallas Home? Tax Credits Take Stress Out of System Replacement

Tuesday 26 May 2015 01:05
Written by

02_28_13HVAC upgrades in Dallas has become even easier now that the widely trumpeted "Fiscal Cliff" deal, otherwise known as the American Taxpayer Relief Act, has been approved. The act has restored the 25C tax credits, that can be applied to the individual income taxes of homeowners who purchase and install certain types of qualified high-efficiency home HVAC upgrades.

The 25C tax credits vary based on the type of HVAC upgrades involved, up to a total of $500. The credits are retroactive for 2012 and are valid throughout 2013. They apply to new equipment installations or HVAC upgrades at a principal place of residence. If you have already taken energy tax credits since January 1, 2005, the 25C credits cannot be applied.

Here are some explanations of the tax credits that are available to consumers:

$50 credit:

Advanced main air circulating furnace fan that annually uses no more than 2 percent of the total energy used by the furnace.

$150 credit:

Natural gas, propane, or oil furnace or hot-water boiler of Annual Fuel Efficiency (AFUE) 95 or higher.

$300 credit:
  • High-efficiency electric heat pump with a minimum 15 Seasonal Energy Efficiency Ratio (SEER), 12.5 Energy Efficiency Rating (EER) and 8.5 Heating Seasonal Performance Factor (HSPF) for air-source heat pumps, and 14 SEER, 12 EER and 8 HSPF for packaged heat pump systems.
  • High-efficiency central air conditioner with a minimum 16 SEER and 13 EER for split-system central air conditioners and 14 SEER and 12 EER for package-system central air conditioners.
  • Natural gas, propane or oil water heater with a minimum energy factor of 0.82 or a minimum thermal efficiency of 90 percent.
  • Electric heat pump water heater with a minimum energy factor of 2.0.
Homeowners with eligible HVAC upgrades can claim the 25C tax credits by filling out Form 5695, Residential Energy Credits, and including it with their standard income tax form. Contact your tax preparation professional for more specific guidance on claiming 25C credits.

Crawford Services, Inc. is a professional heating, air conditioning and plumbing services provider for Dallas and communities throughout North Texas.

Dallas Heating and Air Improved with Use of Programmable Thermostats

Tuesday 26 May 2015 01:03
Written by

03_05_13Optimize your Dallas heating and air conditioning residence by using a programmable thermostat. With a programmable thermostat, you can expect almost total control over the operation of your home heating and cooling systems, along with substantial savings on your monthly home comfort expenses.

To get the best performance from your Dallas heating and air conditioning system, stick to the following programmable thermostat best practices:
  • Use the unit's set points: The set points are pre-programmed temperature settings that optimize your HVAC system's ability to operate at different levels. With set points, you can set the system to reduce operation during times when it's not needed, such as during the day when your home is empty. The set points will then automatically increase heating or cooling to make your home comfortable in time for everyone's return from work or school. Maintain set points for at least eight hours at a time for maximum efficiency.
  • Avoid abrupt temperature setting shifts at the thermostat: If your home's environment is not comfortable enough, it's tempting to make abrupt, large setting shifts at the thermostat to compensate. Avoid this temptation. Quick changes at the thermostat do not make your Dallas heating or air conditioning system work any faster. Instead, you'll only waste energy and money. Use smaller adjustments at the thermostat to allow the unit to work at its best by sensing indoor temperature changes and gradually increasing heating or cooling.
  • Use manual overrides and vacation features sparingly: If needed, set points can be manually adjusted on the spot or set to operate consistently for extended periods. They are convenient features, but overusing them eliminates the benefits of having a programmable thermostat. Use vacation holds only for times when you'll actually be away from your home for days. Avoid using overrides and vacation settings for day-to-day operation of your HVAC systems.
Dallas heating and air conditioning customers can have full confidence in the sales, maintenance and repair provided by Crawford Services, Inc. Contact us today for more information on the many benefits of programmable thermostats and for expert help selecting a model that will work best for your home.

Humidifiers: A Whole-House System Will Provide Greater Relief In Your Dallas Home

Tuesday 26 May 2015 01:00
Written by

03_21_13Humidifiers are often overlooked in the Dallas area, but they can do some real good in many homes. Despite the mild, humid North Texas climate, our air does get cool and dry enough to cause problems during the fall and winter seasons.

Ideal relative indoor humidity is around 40 to 50 percent. In winter, though, indoor humidity can fall below 30 percent, leaving you with problems such as dry eyes, static shocks and a persistent chilly feeling. It can ruin your artwork, cause cracks in the molding and walls and split the wood flooring causing eventual large dollar repairs.

Portable humidifiers help somewhat, but they're effective only for one or two rooms at a time. The need for daily filling and cleaning makes them a hassle to use too.

Whole-house humidifiers are more effective and more convenient. These units are installed directly into the HVAC system. As air passes through the system, the humidifier releases water vapor into the air. The air, now at a comfortable humidity level, is distributed throughout your home through your HVAC ducts.

Because a whole-house unit draws water from your home's plumbing system, you'll never have to refill it. The unit needs upkeep only once or twice a year.

With a whole-house humidifier, you can improve your comfort level in a number of ways.
  • Protect your skin – Increasing indoor humidity can relieve wintertime discomforts such as itchy dry skin, cracked lips, dry eyes and a scratchy dry throat. Humidifiers may help prevent nosebleeds, too.
  • Lower cold and flu risk – Your respiratory tract needs sufficient moisture to keep out the microorganisms that cause colds and flu. What's more, most viruses doesn't survive as well in humid air, so proper humidity levels may reduce the number of viruses in your home.
  • Ease respiratory symptoms – If you do happen to catch a cold or the flu, dry indoor air will irritate and inflame your respiratory tract, making your symptoms worse. Properly humidified air will help you breathe easier. If you have asthma, you may find improved humidity results in fewer attacks.
  • Feel warmer – Dry air draws moisture from any surface it can, including your skin. This drying process creates an evaporative cooling effect that makes you feel chilly. With proper humidity levels, you'll feel warmer and may be able to turn your thermostat down to lower your heating expenses.
  • Avoid static electricity – When the air is dry, metal items can build up more of an electric charge than they can in humid air. The result is static electricity. Humidifiers help prevent the painful shocks and clingy clothing static causes, as well as damage to sensitive electronics from static jolts.
  • Prevent costly repairs to your woodwork , walls, and artwork - When humidity drops below 42% bad things in the home can begin to happen. Wood will begin to crack and artwork will dry up. Many of these damages are unrepairable.

Solar Energy Is An Option With the SunSource Home Energy System

Tuesday 26 May 2015 00:56
Written by

03_19_13Solar energy may sound like a great idea in the sunny area of DFW, but some of the complicated setups involved with Solar may be frustrating. If you're just getting started with solar power considerations, you need a simple, cost-effective system. The SunSource Home Energy System from Lennox gives you just that.

The SunSource system consists of a high-efficiency air conditioner or heat pump integrated with roof-mounted solar modules (panels). To run your A/C or heat pump, the system uses solar energy before it draws electricity from your power company.

Electricity not needed for heating or cooling can be put toward powering other home electronics. After that, surplus electricity is fed back to your power company, giving you a credit on your next bill.

Other advantages of the SunSource system include:
  • Simple installation – Because the system is solar-ready, it doesn't require alterations during installation. Although it still requires professional installation, this simpler process makes things faster and cheaper for you.
  • Flexibility – The system allows you to start with as little as one solar module and add up to 15 panels. You can get started immediately even if your budget doesn't allow for a system powered fully by solar energy.
  • Long life span – The Dave Lennox Signature Collection condensing units used in the SunSource system carry a limited warranty for 10 years. The solar modules are guaranteed to perform at no less than 80 percent for 25 years, and the microinverters are covered by a 15-year limited warranty.
  • Microinverter technology – An inverter is what turns the direct current (DC) electricity from the solar panels into alternating current (AC) your home can use. While many systems use a single invertor for all the panels, the SunSource system uses a microinverter for each individual solar panel. This allows for better performance optimization of each panel.
  • Precision monitoring – Using your home's broadband Internet, the SunSource system updates you with real-time performance data. You'll be able to monitor your system's status, energy production levels and positive environmental impact.
If cost concerns are holding you back, keep in mind there are a few ways to reduce your expenses.

Because the SunSource system is connected to your utility company's grid, you may be eligible for government and utility company rebates that lower your total installation costs.

The condensing units used in the SunSource system are Energy Star-qualified, so they're eligible for the federal Residential Renewable Energy Tax Credit. Install your solar energy system before Dec. 31, 2016 and you'll be able to claim a 30 percent tax credit on your costs.

There are also financing options available to break the cost down into small monthly payments and then allow the utility savings to offset the payment amount.

If you're interested in adding the SunSource Home Energy System or any other energy-efficient HVAC equipment to your home, please contact us at Crawford Services. We have provided home comfort services in Dallas and the surrounding area for over 30 years.

Energy Star’s Most Efficient Label, What It Means To Dallas Homeowners

Tuesday 26 May 2015 00:53
Written by

04_02_13The Energy Star label is a trustworthy indicator of the energy efficiency of new appliances, electronics, HVAC equipment and other types of energy-consuming products. The U.S. Department of Energy and the U.S. Environmental Protection Agency have established criteria of energy efficiency that products must meet before they are granted Energy Star status. In 2011, the program became even more valuable to American consumers with the introduction of the Energy Star Most Efficient label.

If a product has earned program certification, it can be expected to use significantly less energy than a comparable noncertified model. With the introduction of the Most Efficient label, this already exclusive pool of energy-efficient appliances and equipment has been narrowed even further. Only the top 5 percent of products that have already been granted Energy Star certification can be further designated an Energy Star Most Efficient item.

Most Efficient products can be considered the "best of the best" of their category when it comes to energy use and savings. You will find the label on:
  • Furnaces
  • Air conditioners
  • Boilers
  • Geothermal heat pumps
  • Televisions
  • Clothes washers
  • Refrigerator-freezer combinations
  • Computer monitors
  • Ceiling fans
  • Ventilating fans
  • Windows
When you choose products that have earned the Energy Star Most Efficient designation, you'll be selecting items for use in your Dallas household that use the least amount of energy and save you the most money possible on your regular utility bills. For example, furnaces with the Most Efficient designation will have an Annual Fuel Utilization Efficiency (AFUE) rating of 97 percent or higher. This means that 97 percent of the energy in the fuel the furnace uses will be converted to heat that can be used in your home.

You can find the label on product literature, point-of-sale material, brochures, Web sites, the product's EnergyGuide label and on the product itself.

Crawford Services, Inc. provides white glove best in class heating and cooling replacement solutions, maintenance and repair and annual tune ups for customers in the Dallas area. Contact us today for more information on the Energy Star program, the Energy Star Most Efficient Label and what equipment and appliances with this designation can mean for your overall energy costs and consumption levels.

Heat Pumps Are Also Effective Coolers for Your Dallas Home

Tuesday 26 May 2015 00:50
Written by

08_08_13The term heat pumps might make you think that these highly efficient HVAC appliances are used for heating only. In fact, heat pumps are very efficient at providing both heating and cooling, especially in an area of relatively high temperatures such as North Texas. Here is a brief overview of how heat pumps work to keep your home cool.

The basic function of a heat pump is to capture heat and move it from place to place. Air-source heat pumps capture and release heat in the air. Geothermal heat pumps use the ground as a source of heat and a place to expel heat. Water-source heat pum

ps use lakes, ponds, wells, aquifers or other water sources for moving heat.

Air-source heat pumps, the most common variety, contain five main components that allow heat to be absorbed and released: the condenser, evaporator, compressor, air handler and reversing valve. Heat transfer is accomplished using a liquid refrigerant that changes state from liquid to gas and back again, depending on where it is within the system. This change in state allows the refrigerant to absorb or release heat.

The refrigerant is contained inside two sets of copper coils, one inside your home and the other in the heat pump's outdoor unit. The refrigerant circulates through the coils and moves in and out of your home. During cooling operations, the indoor coils capture heat and transfer it to the refrigerant, which evaporates into a gas. This hot gas is moved to the outdoor coils, where the gas is condensed and pressurized, causing it to return to a liquid state. The heat is released into the outdoor air as the refrigerant changes state. Inside your home, the air handlers circulate the cool air produced by this process. When heating is required, the reversing valve reverses the flow of refrigerant. The outdoor coils become the source of heat capture and the indoor coils the source of heat release.

Compared to standard central air conditioners and furnaces, heat pumps are very efficient and cost-effective sources of cooling and heating. They are reliable and sturdy pieces of equipment that hold up well to the stress of operation. They also run relatively quietly and cleanly.

Crawford Services, Inc. is one of the premier providers of HVAC services, including sales, installation and repair, in the Dallas and North Texas area. Contact us today for more information on heat pumps and how they can be used to provide excellent levels of cooling in the summer and heating in the winter.

Your HVAC System Should Be Part of Your Secure-Home Strategy This Summer

Tuesday 26 May 2015 00:46
Written by

08_20_13Your HVAC system should continue while you're on vacation this summer. Burglars casing neighborhoods look for homes that appear temporarily vacant, and one with a compressor humming away is less likely to look that way. Making your home look occupied can be as important as locking your doors. Follow these tips to keep your home safe and energy efficient while you are away.

Preparing your air conditioner
  • Seal air leaks around windows and doors to lower your HVAC service load. You can also shut the drapes, but do not do it if you normally leave them open. A burglar may notice this.
  • Perform preventive HVAC maintenance before you leave. Change the filters and do routine cleaning on the outdoor unit and the indoor vents. If you have not had an A/C checkup yet this season, make sure to schedule one so that your A/C will function at its best while you're away.
Climate control
  • Set your thermostat a few degrees higher to save energy, but remember that houseplants, pets, appliances and electronics need climate control. It is unwise to allow the home to get too hot.
  • If you have a zoning HVAC system, you may choose to raise the temperature in some of the zones more than others to save even more on energy costs.
  • The weather may change and things may get warmer while you're gone. Have your pet sitter or anyone who checks on your home let you know if it feels too cool or too warm. You should also leave them the phone number for your A/C tech in case something goes awry with your HVAC system.
Other ways to protect your home
  • Have a friend or neighbor collect your mail and newspaper every day.
  • Use timers for lights so they will switch off or on occasionally.
  • Add motion-detecting lights and other landscape lighting.
  • Hire someone to mow your lawn once a week (if it's growing that fast).
  • Turn off the power to your garage door.
For more advice about your air conditioning system or other home issues, please contact us at Crawford Services, Inc. We provide quality, professional service to the Dallas area and look forward to serving you.

HVAC Upgrades Made More Affordable With Tax Credits Available Through 2013

Tuesday 26 May 2015 00:42
Written by

10_01_13Another benefit of an HVAC upgrade to improve heating and cooling efficiency came from Washington, D.C., earlier this year. The 25C Tax Credit for upgrading residential systems was reinstated after having been allowed to lapse in 2011. Congress has taken renewed action to encourage installation of an HVAC upgrade that conserves energy while delivering gains in performance and comfort. The tax credit applies to qualified equipment purchased and installed from Jan. 1, 2012 through Dec. 31, 2013. Unlike a mere exemption, a tax credit reduces the tax due at the bottom of your tax return, putting money directly back in your pocket. In addition, you’ll receive the savings from lower utility costs and a range of options available on high-efficiency equipment.

Tax credits are equal to 10 percent of the cost of purchase and installation of a high-efficiency HVAC upgrade. The credit is capped at a system maximum of $500. This includes $300 for an approved air conditioner or heat pump, $150 for a matching furnace and $50 for an advanced blower with high-efficiency ECM technology. The individual requirement for each HVAC component are as follows:
  • A split system air conditioner must have a SEER (Seasonal Energy Efficiency Ratio) of at least 16 and an EER (Energy Efficiency Ratio) of at least 13.
  • A split system heat pump must have a SEER rating of at least 15, a 12.5 EER and an 8.5 HSPF (Heating Seasonal Performance Factor).
  • A gas furnace must have an AFUE (Annual Fuel Utilization Efficiency) of 95 percent or greater.
  • An advanced air circulation blower fan must consume no more than 2 percent of the total system energy.
  • Geothermal systems that meet or exceed the requirements of the Department of Energy’s Energy Star program qualify for a one-time credit of 30 percent of the cost of the system. This credit is retroactive to include units installed after Dec. 31, 2007, and runs through 2016. The same credit is available for qualified residential solar systems.
Crawford Services, Inc. provides quality air conditioning, heating and plumbing services to North Texas homeowners. Ask us about a high-efficiency HVAC upgrade to qualify for the 25C Tax Credit before it expires.

Heater on the Fritz? Do Your Homework Before Selecting an HVAC System for Your Plano Home

Tuesday 26 May 2015 00:39
Written by

10_03_13In North Texas communities such as Plano HVAC systems occasionally break down, as you probably know all too well. When this happens, you'll want to call your local Plano HVAC company and arrange repairs right away, or if you heating or cooling system is old enough, or severely malfunctioning, consider getting a whole new system. With winter only a few months away, here are some tips for selecting a new HVAC heating system for your Dallas area home:

First of all, you want to be sure you're getting the most energy-efficient model you can. In Plano HVAC use can drive your energy bills through the roof, so the less energy it uses, the better. In addition, the most efficient furnaces can qualify you for a federal tax credit.

So find a furnace bearing the blue Energy Star logo, which indicates it's been proven to save money and energy. Also look for features that will save you energy, such as a variable-speed blower that usually operates at a slower, more continuous speed. This uses less energy and provides more even heating.

Also check the AFUE (Annual Fuel Utilization Efficiency). That's how much fuel the unit turns into heat vs. how much is given off as exhaust in a given year. A high-efficiency furnace is one that sports an AFUE of at least 90 percent, meaning it converts nine-tenths of the fuel that goes into it into heat for our home.

You probably won't get an oil-burning furnace, though. Most new furnaces run on natural gas, whereas oil furnaces tend to be found in older homes, typically in the Northeast. And if you get a natural gas furnace, be sure to get a sealed combustion unit. This seals the burner off from the air in your home, helping you avoid carbon monoxide poisoning.

You may also opt to get a heat pump, which extracts heat from the outdoor air and pumps it into your home. They tend to work ineffectively in extremely cold temperatures, but are perfect for your milder, Plano HVAC needs.

For more help with buying a furnace, or other HVAC advice, please contact our experts at Crawford Services, Inc. We're the trusted source for heating and cooling services in Plano and the North Texas area.

Your Dallas HVAC Will Work Better This Fall If Your Insulation Is Up to Speed

Tuesday 26 May 2015 00:29
Written by

10_23_13This past summer, your Dallas HVAC system’s performance was affected in part by your home’s insulation levels. Just as insulation helps keep cool air in, it also helps keep cold winter air out. As the seasons change, it’s important to assess your home’s insulation to ensure there’s a sufficient amount to maximize Dallas HVAC performance this winter. Here’s how.

Understand R-Values

Every type of insulation resists heat flow to a certain degree. This “thermal resistance” is called the R-value. Higher R-values indicate greater thermal resistance. They depend on the material, density and thickness.

Assess Important Areas for Insulation Levels

The easiest places to check for adequate insulation are unfinished attics and basements. It’s impossible to see how much insulation is behind a finished wall unless you have an infrared camera. Consider an energy evaluation to take advantage of this technology and find out where insulation is lacking in finished areas of your home.

Know What Products are Available

• Blanket insulation in the form of batts and rolls are flexible products made from rock wool or fiberglass. They are most appropriate for use between floor and wall joists or ceiling rafters.

• Loose-fill insulation is made from cellulose, rock wool or fiberglass and must be blown into place with professional equipment. It is most often used in unfinished attics, wall cavities, and in irregularly shaped areas.

• Foam insulation made from open- or closed-cell polyisocyanurate or polyurethane is sprayed into place with special equipment. Closed-cell foam in particular provides higher R-values while taking up very little space.

• Rigid insulation comes in flat panels or curved shapes to cover piping. They provide the greatest R-value when space is limited. Aside from insulating pipes, rigid insulation is sometimes used to insulate foundation walls.

• Reflective insulation provides a radiant barrier to reflect heat and reduce downward heat flow. Its best application is in the attic of a warm-climate home.

Use this knowledge to improve insulation and make it easier for your Dallas HVAC system to perform admirably this winter. Then contact us at Crawford Services to learn more about efficient home heating.

Does Your HVAC System Need a Fall Tune-up?

Tuesday 26 May 2015 00:25
Written by



A fall tune-up for your HVAC system is something that should never be put on the back-burner. As a matter of fact, tabling your tune-up can be downright dangerous.

But, a thorough check is more than just checking the thermostat and changing out the air filter, which you can do by yourself. A professional fall tune-up will include the inspection of your entire HVAC system, ensuring that all electric, mechanical and gas-bearing parts are in proper working order and safe winter operation. After all, wouldn't it be nice to have a little peace of mind this winter, knowing that you don’t have to worry about your furnace going out?

04_04_13A professional HVAC technician will start the fall tune-up by checking your thermostat. This is “mission control” for all of your winter comfort. If your control panel is not working properly, you need to know about it. A certified technician will be able to tell you if the settings on your home’s thermostat are energy efficient and if the current temperature is right.

There are many parts to your HVAC system besides the AC and the furnace. You need to consider what you air vents have in them and whether or not they need to be cleaned out. Return air vents are a haven for insects and rodents. They build nests and leave droppings, which can lead to respiratory problems if your filter is missing or not working properly. The return air vents can also be a source of decreased efficiency if they have holes in them or are not properly insulated. A technician will be able to check for these common pitfalls during the fall tune-up.

The mechanical parts used within your HVAC unit are complex and delicate. When they sit for a full summer or winter without moving, they tend to rust and get covered in dust and dirt. Gas connections also need to be checked. This is a necessity to ensure there are no leaks. The pilot light will also be tested and litduring your yearly fall tune-up.

07_16_13As the technician reaches the heart of the furnace, he is basically doing janitorial work. These units do not run well, or at all, when there is an accumulation of dirt and debris. This can also be the case when insects have nested in there. Either way, they need to be cleaned out. At the same time, all electrical connections need to be tested and cleaned out of the HVAC system, especially close to the heat exchanger and the burner.

While checking the electrical connections, the technician will also test the motors and controls for effective operation. In some cases he may need to apply lubrication to the blower bearings and blower motor. This is a recommendation by the manufacturer and it is best to stick to these recommendations.

Adjustments to the burner and heat exchanger come next. This is a critical part of the fall tune-up and helps ensure the safety of your family in your home. Not only do you run the risk of a fire if the burner and heat exchanger are not working properly or have grimy debris all around them, but if the heat exchanger is cracked, you will have a carbon monoxide problem circulating through your home. Carbon monoxide is the result of organic matter that did not complete the oxidation process. Basically, the matter did not complete combustion, which in turn releases the by-product of carbon monoxide.

Did you know there are hundreds of deaths every year from carbon monoxide poisoning? We sometimes don’t think we need a fall tune-up because we start up our furnaces and they work. Even with the dirty burning smell that comes every year, we feel comfortable that everything is safe. The smell we associate with the switch to heat is normal and safe, but the threat of carbon monoxide is odorless and deadly. While most people think carbon monoxide smells like a car exhaust, it doesn’t. Carbon monoxide is an odorless, colorless, tasteless and toxic gas. If you are exposed to enough of it (100PPM or more), it can kill you in minutes, without you even knowing it is happening. It does cause flu-like symptoms, but most people think they are getting the flu and stay in their home – only exacerbating the problem.

A fall tune-up is a great time to think about installing a carbon monoxide detector in your home, which allows you to know if your symptoms are CO2 related. They do not have to be installed on the ceiling and they can probably save you and your family’s lives. Long-term exposure to low levels of carbon monoxide can lead to depression, confusion and memory loss

.Regular Maintenance Reigns Supreme

There are a few things that you can also do on your own to make sure that your HVAC system stays in proper running order throughout all seasons. It is highly advisable that you make sure there is nothing around your furnace that is flammable or can easily catch on fire. Lawnmowers, gas cans, or even dead grass that has fallen off your lawnmower are bad things to store around your unit. There is compressed air being heated in the furnace and if one of them catches the pilot light, you can easily have a home fire.

HVAC systems also need to stay clean on the outside as well. Cleaning off the dust and debris that have accumulated around the unit is a good idea. You can do this once every few months. During the process, take the time to test your heater while it is warm out, so that you can be made aware of any issues and relay them to your fall tune-up tech.

crawford_1_10_13Proper air filter changes are imperative and this process should be performed monthly for best results. Even changing the filters on a three-month rotation will add extra life to your unit by increasing the airflow and efficiency of the HVAC system. The number one reason you do a fall-tune-up is to make sure it is in proper working order - and dirt is the number reason HVAC systems fail. If you keep yourair filter changed every month then you make everyone’s job easier and you have a happy and running furnace every winter.

Digital Thermostats Can Make a Big Difference in Your Bills

Tuesday 26 May 2015 00:22
Written by

In Dallas, a digital thermostat is a truly useful tool to make sure your temperature control is as efficient as it can be. Digital thermostats are definitely a unique upgrade over the old analog thermostats, and they can also be easier to use.

Analog thermostats, and those with the plastic wheels that set temperatures, use mercury vials to take temperatures - and they also contain a lot of moving parts. While these were useful back in the old days (or should we say better than nothing at all), they have quickly become dated. That is because they, like all other thermostats, are hung on walls and are constantly being bumped or jarred. So why does that make it any better for digital thermostats? Well, the old case and wheel thermostats are easily thrown off and constantly need to be adjusted.  Digital thermostats, however, do not require recalibration and are not harmed by typical wear-and-tear type use.

thermostatWith the recalibration needed for analog thermostats, plus the fact that they are not able to change temperatures on a schedule, upgrading to a digital thermostat can save you quite a bit of money.  Digital thermostats are programmable, giving homeowners the ability to cut their electric bills by as much as 20 percent.  When programmed to recognize the times when you are home and away, a digital thermostat is able to maintain comfortable temps while you are home and consume less energy while you are away. Using thermistors to take temperature readings instead of mercury, digital thermostats return readings that are more accurate.  They are also safer to use because there is no risk of mercury leakage.

If you are ready to increase the energy efficiency of your home, call Crawford Services today.  Our technicians can help you find the right thermostat to fit your living situation, and give you the ability to save big on the cost to run your home.

Zoning Systems: Could Your Home be More Efficient?

Tuesday 26 May 2015 00:16
Written by

If your Dallas home has a zoning system, then you can expect to not only save up to 30 percent off your energy bill, but also receive optimal comfort in every room of your home. That is because you are taking the central forced air system and making it more efficient by delivering conditioned air to rooms that need it and cutting it off to rooms that do not.

Okay, so you are wondering what a zoning system is how this is accomplished. Well first of all, consider what you already know. Your heat and AC come out of a main HVAC supply system, either in your basement, attic or a wall closet, and the conditioned air gets delivered through air ducts. The air ducts lead throughout your walls, ceiling and floors to deliver this conditioned air to each room simultaneously, cool or heat.

03_05_13Many years ago, that was the genius invention known as central air. It made it so that conditioned air was not just blowing through a window unit in your living room, trying its best to reach your bedrooms while over-cooling or over-heating the family room in the process. It provided an insulated portal for the conditioned air to travel through so it can be delivered to each room at the same time.

But the problem we are running into now is that the central air unit is controlled by a single thermostat on a wall in the hallway and when that hallway is at the desired temperature, the unit turns off to all rooms at once. In the summer, some rooms get warmer than others because they are closer to an exterior wall or they are upstairs. Heat rises and your upstairs rooms catch all the heat from below. Reverse the scenario for winter and your downstairs and basement rooms stay uncomfortably cold.

So the next evolution in home climate control is zoning systems. They actually work much like the name sounds. They heat and cool in zones and shut off those zones when they are at the desired temperature. With a zoning system, you now have a thermostat in each room and it can tell your HVAC system if it needs to be cooler or warmer. It can keep your air running when your hallway is at the right temperature and not affect the temperature of other rooms.

Okay, so we already know what you’re thinking: “This is going to cost a fortune. I am going to have to buy multiple units to control this in each room and spend thousands of dollars just to make it work.”

Actually zoning systems are much more affordable and less complex than you think. For those of you who have already tried putting blankets over certain air vents to stop the thermostat from moving and keep the air running, this concept is a lot like that, only more controlled and with less manpower.

Zoning systems use dampers to control the flow of conditioned air. Dampers simply turn off the vent in a room that has reached its optimal temperature. Meanwhile the HVAC system stays running until other rooms with their thermostats have reached the desired setting. When other rooms reach the right temperature, their dampers close off as well. Eventually, the whole house will be at the desired temperature and the HVAC system shuts down until it is necessary to repeat the process. When it comes right down to it, zoning systems are about using your air wisely.

The best part about zoning systems is the fact that they actually have minimal effect on the way your house is setup, depending upon the system you choose to use. Thermostats in each room can connect to a main thermostat through wired or remote connections. Then it’s just a matter of installing your dampers and controls to them. All of this is done without cutting into the drywall since it is not necessary to replace or reroute any of the ductwork.  Once you have the room temps set in the right place and the air routing parts installed, you are free to sit back in your recliner and enjoying your home.

Not only are you saving 30 percent off your HVAC energy costs, but you are biting into a huge chunk of your overall utility bill. Did you know that the U.S. Department of Energy estimates that 40 percent of your total household utility costs come from climate control systems? Do the math and you will quickly see how this benefits both your pocketbook and the overall longevity of your HVAC system - when the HVAC system is used more efficiently it tends to have a longer and more effective lifespan.

Solar Energy Works in the Winter and Summer

Tuesday 26 May 2015 00:13
Written by

Solar energy saves money! That is the first and most important thing for you to know about installing a solar energy system in your Dallas home. Just like with any renewable energy source, solar energy is designed to save you money and in the process, benefit the environment.

Thermal energy produced in energy plants requires the use of fossil fuels, which are in turn burned and released into the atmosphere. Solar energy is absorbed by converters, then sent to use in your home, and in many cases can be designed to power your HVAC system.

What is especially unique about a solar energy powered HVAC system is that it works in conjunction with your utility company. As you probably already know, solar energy is powered by the radiant heat of the sun, not heat. This means it works just as well in the winter as it does in the summer. Basically, this system uses the energy it converts to power the heating and cooling system in your home. Whenthe AC or heat pump aren’t running, the energy created through the solar panels is routed through the home and can power major appliances like the refrigerator, the water heater or a TV.03_19_13

As if that isn't incentive enough to invest in a solar energy HVAC system, there is more. Many solar systems are capable of overproducing for your home’s energy demands. This means that any extra energy created off your unit can be sent back to your utility company, which in turn may give you a credit.

All of us here in Dallas have experienced the pain of paying a high utility bill that is equivalent to that of our mortgage payment. What you may not realize is that on average, 56 percent of that bill comes directly from your HVAC climate control operations. Can you imagine cutting 90 percent of that out with a solar energy HVAC system? Additionally, you can look forward to state and federal tax credits and insome areas, utility credits.

To learn more about solar HVAC systems, call Crawford Services.

The condition your HVAC system can directly impact your ability to sell your house. Most homebuyers find the general upkeep of a house, the condition the AC and furnace are in and how old the house is, to be of the utmost importance. In fact, these three factors are what drive them to consider further activity with purchasing your home. So you can imagine why it so important to have a great HVAC system that not only runs, but has been taken care of

The condition your HVAC system can directly impact your ability to sell your house. Most homebuyers find the general upkeep of a house, the condition the AC and furnace are in and how old the house is, to be of the utmost importance.  In fact, these three factors are what drive them to consider further activity with purchasing your home.

03_05_13So you can imagine why it so important to have a great HVAC system that not only runs, but has been taken care of and maintained. That means the units need to be wiped down (inside and outside unit), blown out and have debris free parts inside of them. If there is evidence of leaves and nesting rodents or insects in the outside AC unit, that indicates to a homebuyer that it has been disregarded and he/she assumes that is the way it has always been.

It is best to maintain your HVAC unit with a checklist that you fill out every fall and spring. Post this checklist on a wall beside your HVAC system and make sure that all checklists from previous seasons are present on the wall. That way a homebuyer can see all of them and realize that you have taken care of your climate control system in a very responsible way. On the checklist, you need to make sure that you include all the basic do-it-yourself tasks. This includes changing out your air filter (monthly), cleaning out and wiping down all external parts and surfaces, keeping all flammable or material items away from the unit and its combustible parts, cleaning out the condensate drip line and keeping all weeds trimmed back and away from the outside AC unit.

Your HVAC checklist should also include a section from the outside service professionals who come in and clean out internal parts, check gas line connections and pressures, test refrigerant levels, test the capacitor and test the electrical connections. Include these areas on the checklist and have your service man initial them.

HVAC for New Construction: Know How to Make the Right Decisions During the Building Process

Tuesday 26 May 2015 00:05
Written by

Choosing the right HVAC for new construction can help to make a big difference in the future. After discussing the options with your architect it’s important that you seek a specialist’s advice for all HVAC for new construction projects – there’s a lot to think about when it comes to heating and cooling your future home efficiently.

DHomeAdLarger homes can be zoned for maximum energy efficiency – there is really no point in heating up large portions of a property which are not in regular use – the ability to close off portions of a larger property can make a big difference to both the energy bills and comfort of a home. After all, isn’t it better to keep a small portion of your home warm and cozy rather than keeping the entire property at a cooler, affordable temperature?

So what other things do you need to think about when choosing the best HVAC for new construction?

You will only need to consider air conditioning if the air temperature regularly rises above the 85 degree mark, if you are building your home in a cooler climate then air conditioning really might not be necessary. Air conditioning units can, however, make a difference to the overall re-sale value of a home regardless of where it is.

When it comes to HVAC for new construction, size matters - but bigger is not necessarily better.If the chosen system is too large for the property it is supposed to heat it will not run efficiently. Instead it will get caught up in a constant cycle of switching on and off, wearing out components and never quite running at the optimum temperature.

Price does matter when it comes to choosing HVAC for new construction – as with many items in life you get what you pay for. This doesn’t mean that you should necessarily install the most expensive equipment you can find (if you can afford to) but that you ought to ask the professionals about the most reliable systems on the market and pay for a top quality product. Many of the best qualityproducts will have guarantees for around the twenty year mark, boilers may be guaranteed for thirty years – so, it really does pay to purchase a good quality system.

You also need to think about a maintenance contract for the HVAC system in your property. Regular maintenance is essential for any system to run efficiently, so you must be sure that there are some experienced contractors close by who can fulfill a regular contract for you. One of the biggest reasons for emergency call outs on HVAC systems is the lack of regular maintenance.

As you can see, there are many factors to consider when it comes to choosing HVAC for new construction – decisions that are best made under the guidance of a seasoned professional.

Commerical HVAC Needs Require Experienced, Licensed Professionals

Tuesday 26 May 2015 00:03
Written by

commercial-homeA commercial HVAC system is one area where it definitely pays to use only experienced and licensed professional services. Some commercial organizations may neglect this important need because they perceive high costs due to the large amount of area to be covered – but regular maintenance is certainly a cheaper option than waiting until your commercial HVAC system is not working efficiently or in need of replacement.

Taking out a contract with a reputable organization can help to ensure that your commercial HVAC unit is regularly serviced and maintained without any expensive surprises – it really is the affordable option.

It pays to make sure that any HVAC unit is well maintained and regularly serviced in order for it to run efficiently.  It is also imperative to replace any worn parts before they become a major problem. Regularly maintained commercial HVAC units are cost effective and fuel efficient, doing the same job for much less than a unit which is in desperate need of a service. If any unit is not regularly maintained the cost of repair or replacement far outweighs the costs of servicing and maintenance.

One of the most energy efficient methods for commercial HVAC involves zoning, which is certainly advisable in any larger commercial organization.  The same zoning practice can also make a big difference in many private homes. The benefits of zoning your commercial HVAC systems include:

Precise temperature control – each separate area of your commercial building can be kept at a separate temperature by the installation of separate thermostats in each of the individual zones. Some areas may need to be kept warmer or cooler than others - some areas may not need to be heated or cooled at all.

Energy efficiency – zoning is the energy saving option, particularly in a large commercial building. Your company need only pay to heat or cool the areas which require the temperature change. This can have a significant impact on energy bills as well as helping to reduce the carbon footprint of any business. Saving money and helping to save the environment are two very worthwhile benefits of zoning.

Reduced operating and maintenance costs – zoned commercial HVAC units will typically help to reduce operating maintenance costs overall. Maintenance costs may be significantly reduced on two smaller units, as opposed to the cost of replacement of one larger unit.  The smaller units are also typically “worked” less because of the zoning, so they are able to last longer than their larger, overworked counterparts.

The telltale signs of commercial HVAC unit repair are easy to spot yet costly to ignore. Of course, with regular servicing your experienced and professional service engineer will be able to advise you of any potential problems in the foreseeable future, and replace any worn parts before they cause problems in other areas of the unit.  He will also be able to advise you when your unit is getting past its “use by date,” and making replacement the only viable and sensible option.

Signs that it is time for repair and maintenance include:
  •         Your commercial HVAC is clearly not working as efficiently as it should . . . in short, it’s not doing the job it was designed to do. Maybe the air is simply not as cold as it should be when the system is running at full tilt? That’s a sure sign that all is not well with your unit, and it is in need of repair or replacement.
 
  •         If the airflow from your commercial HVAC unit is weak, there is another sign that something is not working as efficiently as it should be. It could be problems with a failing compressor, or another part of your system that has gone corrupt.  Your professional service engineer will know what to do.
 
  •         If some areas are at the desired temperature and others are not, this is another sign that all is not well with your unit.
 
  •         Excessive water pools are yet another sign that your commercial HVAC is in need of urgent attention. These may be gathered close to your unit indicating a damaged drainage tube – if this is allowed to continue it can cause real problems in the not too distant future.
 
  •         Funny noises coming from your commercial HVAC are another giveaway that all is not working as smoothly and efficiently as it should be.  Call your service engineer immediately to prevent a major breakdown.
  •         Funny smells are another sign which you may notice to indicate that the unit is not working efficiently and effectively. You may notice a musty or a pungent smell – both need immediate attention.
The smart business manager knows that it really does pay to have a professional, experienced and licensed engineer to take care of your commercial HVAC needs.  Many commercial HVAC companies provide maintenance agreements that can save you additional money, and help you remember to get those annual tune-ups performed in a timely manner!

Monday 25 May 2015 23:59
Written by

AC Savings can make a big difference in not just one, but two areas of your life – it will ensure that your AC unit will run more efficiently, leading to few breakdowns and lower energy bills, and it will guarantee that your property maintains a comfortable temperature all year round. This will negate the hassle and inconvenience of breakdowns and costly repairs, which have a sneaky way of happening just when you most need your unit.

All items and machine components will need to be regularly serviced to ensure smooth running in the future. Everyone realizes the importance of having their cars regularly serviced - having the oil changed after so many thousand miles - to make sure that the engine runs sweetly and efficiently at the most economical rate possible. The same basis applies to your air conditioning unit. And, theAC savings will soon start to add up if you have your unit serviced regularly by a professional service engineer.

Regular maintenance and servicing of your AC unit will help to:

• Lessen the chances of breakdowns and expensive repair or replacement. In fact, studies in the AC industry have shown that regular maintenance and servicing can reduce the chances of needing expensive repairs by a massive 40 percent. Surely that’s worth thinking about, a few dollars spent now can save many more dollars in the near future.

• Improve the efficiency of your AC unit. This means that your home will be kept at a constant, comfortable temperature during the hot summer months without “hot spots” and “cool spots”.

• Make your AC system last longer. The longevity of an AC system really can be increased by regular, professional maintenance and service. Experts have concluded that regular maintenance of an AC unit can increase its lifespan by up to 30 percent. If your AC unit hasan expected lifespan of fifteen years, you could foreseeably increase that by another four or five years with regular servicing and professional maintenance. This means that you will have four or five years more to save up for a replacement unit. Talk about proactive AC savings thanks to regular maintenance! On the other hand, if you do not have your AC unit regularly serviced, its life could be cut short to 10 years!

• Help to reduce your heating / cooling utility bills. Regular maintenance and service of your AC system can enable it run using up to 30 percent less natural resources – that helps the environment and it also helps your pocket. It really is a win-win situation – good news forthe planet and fabulous news for your bank balance.

As you can see, it really is worth contacting a professional AC servicing company to find out about their regular maintenance and service plans. The majority of AC savings plans incorporate visits twice per year, when the experienced technician will check through a tick list of tasks which must be monitored, serviced, repaired or replaced.

02_28_13Regular maintenance is essential for the smooth running of your air conditioning unit and can prevent things like coil freezing, which may result in extremely costly repairs due to the increased stress which is put onto the compressor. During these routine maintenance checks the AC heating /cooling engineer will:

• Clean the coils – the indoor and outdoor both need attention

• Change the air filter for smooth running

• Check over the fan to ensure that it is working efficiently

• Remove blockages from all of the pipes

• Lubricate all of the moving parts within your AC system

• Check for leaks and repair anything that they find

• Test that the thermostat is working efficiently and accurately

• Recharge the refrigerant unit

• Check the amp draws for efficiency and accuracy

• Replace any belts with signs of wear and tear

• Check all wire connections - tightening anything which has worked loose

Make way for AC savings now and prevent issues during the hot summer months. Those sunny summer days might seem a long way off, but they will be upon us before we know it. Now is the time to check out the regular service and maintenance plans available to you, or at the very least schedule a pre-summer check up of your AC unit. It’s the only way you can be sure to keep cool throughout the summer, while ensuring that your AC system will work as efficiently and economically as possible through the months ahead.

Solar Energy Could Save Your Money on AC Bills This Summer

Monday 25 May 2015 23:53
Written by

Solar energy is great for warming things up, but as the weather is heating up in Texas, has it occurred to you that the energy from the sun can also help you to keep cool?

We all look forward to lazy sunny afternoons… the barbecues, swimming and all of those fabulous activities to be enjoyed during the summer months, so we tend to forget about the downside of a heat wave until it’s too late. Properties can become unbearably hot in the summer, so what do we do? We switch on the air conditioning, of course – and what happens to our utility bills? They soar as high as the temperatures.

Switching to solar energy really can help to save money on your air conditioning bills this summer, and you’ll also have the pleasure of knowing that you’re doing your bit to reduce carbon emissions, use up less fossil fuel and help to save the fragile Earth.  Every little bit helps, you know!

Tapping into the incredible free energy of the sun can not only help the environment, it can also help your family to keep cool and help keep your bank balance low too.

Solar energyair conditioning systems simply generate the energy from the sun and use it to power heat and air conditioning pumps. When the air conditioning system is not in use you can also use the power to operate other electrical appliances in the home – you can even arrange for any excess energy to be sent to a utility company, which is another great way of not only saving money on your own utility bills but also making a little money too.

Solar energyhas one or two major advantages over many other types of energy;
  • Solar energyis free – the sun shines day in, day out through the summer in Texas - at no extra charge. You don’t have to pay for it to shine, and even on the days when it's shielded by clouds or doesn’t look like it’s shining, you can rest assured that it’s still there shining down massive amounts of free energy.
  • Solar energyis limitless – you can’t use it all up – as you harness the energy from the sun, there’s no need to worry about taking somebody else’s share – the sun has limitless energy for everybody, it doesn’t matter how much we use, it will just keep on shining, which is more than can be said about fossil fuel and other energy sources.
  • The more solar panels you install in your home the more energy you will generate for your own use, which means that you will have to utilize less energy from your existing utility company – a fabulous money savings, not only do you save money on your energy bills but you can also get a little cash back.
  • You will also increase the value of your property by installing solar panels and utilizing solar energy. Surveys across the United States indicate that for each $1,000 you save every year by utilizing solar energywill add an incredible $20,000 to the value of your property – not a bad return is it? Saving money actually helps you to make more money on the value of your property.
  • Tax credits are also available for home owners who install solar energy panels to their properties.  You see, solar energy is entirely green; it does not produce any hazardous waste or air pollution, and the more solar energy you use to heat or cool your home, the less energy you will consume from the power plants, which do contribute to pollution and climate change.  Government tax credits are available to encourage property owners to install solar power units, so you may be eligible for up to 30 percent of the cost of the solar energy modules and up to a $1,500 tax credit – check out the details with your tax advisor and see how much cash you could save by simply installing the solar energyunit.
So what are you waiting for? Now’s the time to discover the many benefits of solar energy before the temperatures really start to rise along with your utility bills. Contact a professional company and find out how you can save money in the summer months by utilizing the power of the summer sun to keep your property comfortable and cool.

Building Regulations Could Dictate Your HVAC System Requirements

Monday 25 May 2015 23:46
Written by

Building regulations and other similar codes of practice are generally scrutinized and changed (if necessary) after some sort of catastrophe. It’s all about learning from the past and trying to safeguard the future.

The 1994 California Northridge Earthquake was the major catalyst in the amendment of building regulations across the United States. The necessary changes were noticed in the aftermath of the quake when the four major agencies - The National Science Foundation, FEMA, USGS and National Institute and Standards of Technology - met to analyze the whole situation, taking into account the response and recovery plus the reconstruction projects following the quake.

07_16_13Collectively, they discovered something rather interesting. Although many of the structures and buildings had managed to survive the earthquake, the internals of the buildings had spectacularly failed, including the electrical, plumbing and mechanical elements of the structures. This resulted in the closure of nine hospitals, a total 2500 beds. Something had to change.

New building regulations were brought into force which covered every state, and an emphasis was put into what were labeled “critical buildings” including hospitals and other health care centers, hurricane and earthquake agencies, fire department and rescue stations, among others. The next step was to formulate a standard national code which could be implemented for all buildings, ensuring that they were better suited to withstand the pressures of a major disaster.

A number of IBC codes were put into place (International Building Codes) which were designed to cover the standards necessary of the equipment and fitting of HVAC systems among many other things. Every state has adopted some level of these codes, which fundamentally holds engineers, architects, equipment manufacturers and contractors responsible for the design,implementation and installation of suitable systems which are of the desired quality and design for the corresponding IBC code.

Any firm which does not uphold the standards set by the building regulations runs a real risk of losing their professional licenses. Manufacturers must ensure that their products have a guaranteed performance and pass stringent tests outlined in the relevant building code.

This is particularly important for all manufacturers and dealers of HVAC equipment as these building regulations serve as the first time in which they can be held responsible for the performance of the supplied equipment they manufacture or fit.

These building regulations are now enforced in all states across the country, although to various degrees. It is extremely important that you choose an HVAC company which has the necessary qualifications, certificates and licenses and fits only the equipment which is permitted by law within the building and location you do live or do business. Not only will this ensure that your HVAC is of the highest quality but that it will be reasonably safe should another major disaster occur.

Could a SunSource System Be Right For Your Home?

Monday 25 May 2015 23:43
Written by

04_18_13Have you heard of SunSource Home Energy Systems? The SunSource Home Energy System uses solar energy, captured by solar panels, to generate electricity used to heat and cool your home. A SunSource Home Energy System can even provide enough electricity to power more than just your HVAC system - depending on the climate in which you live, the SunSource System can provide enough energy to power your lights, appliances such as your refrigerator, and more.

A SunSource Home Energy System uses solar modules to collect the sun’s energy and convert it into electricity, which can then be used to power your lights, appliances and other electrical devices in the home. A grid-tied solar energy system is the most common and least expensive of all residential solar systems, and that’s what many SunSource Home Energy customers use. A grid system allows you to use your own solar-generated electricity to save energy and reduce costs. At times when the system isn’t collecting energy, such as at night, power for your home is provided by your local utility company’s grid. Think of it as a “hybrid” system!

Another benefit of SunSource Home Energy Systems are the tax incentives many homeowners are eligible for after installing the system. We should note that most government and utility company incentives that homeowners are eligible for after installing a SunSource Home Energy System will only be able to be achieved if you have a grid-tied system. This is in part because of a benefit of a grid system called “net-metering.” With net-metering, when your home uses power from the power company’s grid, your meter spins forward. The less electricity your home uses from the grid, the slower your meter spins. And when your home gives electricity back to the power company’s grid, your meter spins backwards! In other words, the power company can benefit from your SunSource Home Energy system as well, which is why most homeowners who install a SunSource system are eligible for tax incentives and other benefits. This can make installing a solar system so much more affordable.

You can also install a stand-alone solar energy collection system, known as being off-the-grid, but the tax incentives usually aren’t available with this option. This is because an off-grid system operates independently from the power company’s grid, providing only your home with power. Stand-alone systems are much more expensive because your home is so dependent on this system. But this type of solar energy system could make sense for many homeowners, for example those with homes located in remote areas without utility service. Plus, you still get the added benefit of doing something great for the environment!

SunSource is a grid-tied system, and it uses a high-energy heat pump or air conditioner that’s solar-ready, meaning you can add solar modules to the system whenever it’s convenient for you and your home. The great thing about this is that you can start small, with just a few modules, then add more as your budget permits and depending on the needs of your home. That’s a great benefit of using SunSource - the system can be installed and used in the way that works best for you. And, when the heat pump or AC isn’t running, the SunSource system can operate other electrical appliances in your home, such as the refrigerator and TV.

Another benefit of the SunSource system is how much you’ll learn about your home and its energy consumption. With most utility companies, you simply receive a bill every month that says how much energy your home used, and you pay the bill. Pretty normal, right? With a SunSource Home Energy System, you get so much more than that! SunSource systems come with a communication dashboard, which shows you the performance information for each solar module. You can also view the SunSource system’s energy production, and you’ll see the environmental benefits of using renewable energy for your home by showing you how much energy you’re saving.

So how do you find out if a SunSource system is right for your home? First, call your a HVAC professional who is certified in installing SunSource systems. Then, they will help you determine if your home’s roof gets enough sun for a SunSource system to work for you. They’ll also help you make sure your roof has enough square footage to install the solar modules for a SunSource system. Next, something you’ll need to do is check with the city planning office or land surveyor in your city, to make sure that there are no building codes that would prevent you from installing a SunSource system. It’s also a good idea to check with your neighborhood governance board, to make sure your neighborhood doesn’t have rules that would block you from installing a SunSource system.

Before installing the SunSource system, the installation professional you work with should also make sure that your home has up-to-date electrical wiring, since there are required specifications that must be met by your home in order to be eligible for a SunSource system. It’s a good idea to ask your utility provider if they offer special price breaks, too. Sometimes power companies offer price breaks in addition to the tax benefits you may be eligible to receive from the government. Once everything has been checked out and verified, your SunSource Home Energy System is ready to be installed!

There are many tax credits you may be eligible for after installing a grid-tied SunSource system. There’s a tax credit for installing the solar-ready heat pump or air conditioner that serves as the platform for the SunSource system. There’s also a federal solar credit that equals 30 percent of the cost with no limit of the SunSource solar modules - including installation! As you can imagine, this makes installing a SunSource Home Energy System much more affordable. You can also potentially have a portion of any solar-ready products you purchase be covered by the tax credit. In most cases, in order to be eligible for a federal tax incentive, you just have to install a solar-ready outdoor unit and attach it to at least one solar module. Then, your home will be able to benefit from using solar energy, and your wallet will benefit from the tax incentives!

Installing a SunSource Home Energy System is a fantastic way to save energy costs and help the environment. If you’re interested in installing a SunSource system, contact your local HVAC installation professional today.

Wednesday, 08 February 2012 19:09 When Furnace Noise Shouldn’t Be Ignored

Monday 25 May 2015 23:40
Written by

Causes of Furnace Noise

A noisy furnace can be caused by a number of things. A squeaky furnace could be a sign that a belt has reached the end of its usefulness or that the bearings in the motor need lubricating. A rumbling noise in your furnace can be the result of a clogged filter or dirty gas burners. If your Dallas furnace or HVAC equipment is making noise, pay attention!

Having the cause of a noisy furnace assessed by a heating, ventilation and air conditioning (HVAC) professional is important. Furnace noise could be the first sign that the unit needs repaired or replaced, and an indication that it could fail at any time. Noise from a clogged filter or dirty burners could be more serious. A furnace in grave need of cleaning can be a fire hazard. In addition, a cracked heat exchanger, another possible cause of furnace noise, could allow combustion gasses to enter your living space and cause a serious health hazard.

If you’re unsure whether your Dallas area furnace needs repair, it’s a good idea to have it examined by an HVAC contractor. Crawford Services Inc., serving North Texas home and business owners for more than 30 years, can help you determine the cause of your furnace noise.

3 Benefits Of Radiant Heating For North Texas Homeowners

Monday 25 May 2015 23:35
Written by

When you're considering alternatives for heating your home, consider the benefits of radiant heating before reaching a decision. The technology behind radiant heating has changed over time, and now it's easier than ever to install it in new homes or retrofit existing homes. These are the top three reasons for considering this type of heating in your North Texas home:

1. Comfort. Radiant heating systems gently heat everything in the room. Your floors, furniture and walls absorb the heat and retain it, unlike forced-air systems, whose heat is quickly lost when the furnace doesn't run long enough to let the heat penetrate the physical components indoors. Heat rises, and as the floors warm the temperature of everything inside the room warms as well. Your feet will never be cold with radiant heat, and children playing on the floor won't feel any chill.

Radiant heating is quiet, since there's no air handler running and air blowing through ducts to deliver the heat. Homes with radiant heat are easier to keep dust-free, and anyone with allergies or asthma benefits from these systems.

2. Energy efficiency. One of the benefits of radiant heating is that your home is zoned, which means that you only need to heat the spaces you're currently using. Each zone has its own thermostat that you can turn down or up, depending on the time of day and personal preferences. The thermal efficiency of radiant heat is 100 percent, higher than forced-air heating systems. Energy losses through ducts can reach 30 percent or higher, something you'll never worry about with a radiant system.

3. Space-saving. Radiant systems do not use any space for ducts or require a separate space for the air handler. When arranging furniture or decorating a home, a radiant system gives homeowners more flexibility, since blocking ducts and registers is never a concern.

If you'd like to learn more about the benefits of radiant heating and its suitability for your present home or one you're planning, please contact us at Crawford Services, Inc. We provide quality HVAC services for Dallas and North Texas homeowners.

Buying A New Heating System? Your Options Are Plentiful

Monday 25 May 2015 23:33
Written by

crawford_11_20_12It does get cold in North Texas during the winter. That means that fall is the perfect time to invest in a new heating system for your home. There are a lot of options when it comes to purchasing a new heating system. Check out the following choices and see which one is best suited for your home.

    • Gas heating systems – Gas heating units such as furnaces or boilers are the most common type. Although energy costs have become much more expensive over the last few years, technological advancements have made furnaces and boilers much more efficient. Look for higher than 90 percent AFUE (annual fuel utilization efficiency) ratings in order to choose the most efficient models. Remember, although higher AFUE-rated models are more expensive, you will save more on your energy bills in the long run.
    • Geothermal system A geothermal heat pump is more expensive than a standard forced-air heating system, at least as far as the upfront costs go. However, these units are also the most efficient and they use the least amount of energy. Geothermal heat pumps use underground (or underwater) pipes in order to absorb heat from the ground and bring it inside. They can also cool your home, by removing heat from inside and "rejecting" it underground. A 30 percent federal tax credit is available for qualified systems.
    • Air source heat pumps – These popular heating systems use the principle of refrigeration to cool you home in the summer (like an air conditioner) and heat it in the winter. Air source heat pumps provide very efficient heating, and are ideal for mild winter climates.
    • Radiant heating – Radiant heating systems use a series of tubes that circulate hot water beneath the home. The heat produced by the tubes rises up through the floor, warming up everything in its path. Because the heat originates from beneath the floor and rises upwards, your home will always be evenly heated.
There are a number of heating options to choose from, so be sure to balance the upfront cost with the benefits of possible future energy savings. For more information, please contact us at Crawford Services, Inc. We provide quality HVAC services to north Texas residents.

Discover The Advantages Of Using Radiant Floor Heating Systems

Monday 25 May 2015 23:30
Written by

crawford_12_6_12Radiant floor heating is one of the most comfortable ways to heat your home in our region. Instead of blowing warmed air throughout your home for short bursts of time, radiant heat provides even, thorough heating that warms all the surfaces in your home, starting with the floors. Hydronic systems use a boiler to heat water, while other type use electric resistance coils to create heat. Of the two, the hydronic system is the most energy efficient.

The heat you get with radiant floor systems is continuous instead of periodic. The heating coils lay in the concrete or on top of the slab and heated water circulates through them. As the floors warm, the heat rises, while the colder air falls close to the floor, where it's warmed once again.

The specific benefits that radiant heat provides include:
  • Hydronic radiant heating can be 30 percent more energy efficient than forced-air systems.
  • Radiant heat is easy to zone, which makes it possible to heat just the rooms you use, a strategy that will lower your energy bills. Each zone has its own thermostat (or can be controlled from a central thermostat), so if you like having cooler bedrooms, you can turn the heat down and keep the living areas warmer.
  • Allergy sufferers won't experience respiratory distress from radiant floor heating, since there's no air movement. The air coming from a forced-air system may carry airborne particles that can irritate allergies or trigger asthma attacks.
  • These systems are durable. The PEX tubing lasts for decades.
  • There is no noise associated with radiant heating.
  • You'll stay warm longer in a power outage with a radiant system. When the objects in your home are thoroughly warmed, they continue to release heat. Solid objects like your furniture, floors and walls release it more slowly than air, which cools quickly. The water inside the tubing also retains heat longer, which increases the length of time your home stays warm.
If you'd like more information about radiant floor heating, contact Crawford Services, Inc. We provide quality HVAC services for the greater Dallas area.

The Ceiling Fans In Your Dallas-Fort Worth Home: Just For A Few Month, Switch Directions

Monday 25 May 2015 23:26
Written by

crawford_1_1_12No doubt you already appreciate the way a ceiling fan's cool breeze mitigates the Texas summer heat, but did you know the ceiling fans in your Dallas-Fort Worth area home can keep you warmer in winter, too?

Heat naturally rises, so without anything to circulate the air, the temperature will always be higher near your ceiling than at floor level. The difference is especially great if you have high ceilings or a heating system that doesn't circulate the air. Using your ceiling fans in winter to circulate air has a number of benefits:
  • Warmer temperatures at floor level
  • More even heating
  • Less condensation on windows
  • Lower heating costs
The trick is to set your fans so the blades rotate clockwise (as you look up at them). Check the motor housing for a switch that lets you choose the direction the blades turn. Running the ceiling fans in your Dallas-Fort Worth home clockwise prevents them from creating a breeze. Instead, they push warm air near the ceiling up and outward, so it circulates toward the edges of the room, then down toward floor level. The result is more even heating throughout the room.

If you have a two-story home, you've probably noticed how the upper level tends to overheat while the lower level stays chilly. A ceiling fan mounted at the top of the stairwell helps bring excess warm air from upstairs down to the lower level where it's needed.

Better circulation of warm air may allow you to turn down your thermostat, too. For every degree you turn your heat down, you could save up to 1 percent on your heating bill, note experts from the U.S. Department of Energy.

Granted, using ceiling fans "both ways" in an area where winter temperatures can range from balmy to frigid – such as here in North Texas – can be tricky. Just make sure you adjust the blade rotation to fit your needs. When the temps move into the 80s in April, you don't want that ceiling fan blowing air toward the ceiling.

For more professional guidance on using ceiling fans in your Dallas-Fort Worth home and finding other ways to improve your home's comfort and energy efficiency, contact us at Crawford Services. We provide top-quality HVAC service around the Dallas-Fort Worth area.

Replacing The Furnace In Your Dallas-Fort Worth Home? Weigh These High-Performance Features

Monday 25 May 2015 23:24
Written by

crawford_1_8Despite the promise of lower energy bills and improved heating, replacing the furnace in your Dallas-Fort Worth home is probably not something you're looking forward to. The wide variety of furnace models available can make it seem like you'll need to wade through pages of technical jargon to find a reliable, energy-efficient model. In reality, though, there are just a few specific, easily understood features you'll want to look for:
  • Efficient ignition systems – Because continuous pilot lights waste fuel, highly efficient furnaces use intermittent, direct spark or hot-surface ignition instead.
  • Sealed combustion – This feature lets the furnace draw outside air into the burner for combustion. Unless your furnace has this feature, it will use warm indoor air for combustion and then exhaust that air outside, wasting energy. Sealed combustion furnaces also greatly reduce the risk of dangerous combustion gases entering your home.
  • Condensing heat exchanger – Heat exchangers draw out heat produced when fuel is burned. A single primary heat exchanger isn't able to draw out all available heat, so highly efficient furnaces have two heat exchangers. The secondary heat exchanger processes exhaust gases from the primary heat exchanger to draw out heat that otherwise would be wasted. When replacing the furnace, look for a "condensing furnace."
  • Variable-speed blower motor – Single-speed blower motors operate only at one speed regardless of how much heat you need. Most of the time, variable-speed motors run more slowly and continuously. This saves energy, reduces drafts, and produces more consistent temperatures.
  • Variable heat output – A furnace with a variable-speed blower motor may also offer the option of varying the heat output between two or more levels. The lets the furnace deliver heat more consistently than would fixed heat output.
Keep in mind, too, that highly efficient furnaces have an AFUE (annual fuel utilization efficiency) rating of at least 90 percent and ideally 97 percent or higher.

For more expert guidance on replacing the furnace or upgrading other HVAC equipment in your home, get in touch with us at Crawford Services, Inc. We provide friendly, trustworthy HVAC services in the Dallas-Forth Worth area and around North Texas.

Are Pollutants From The Attached Garage Seeping Into Your Dallas-Fort Worth Home?

Monday 25 May 2015 23:22
Written by

Crawford_1_17_13The garage attached to your North Texas home makes access to your home, protecting your car and storing household items more convenient, but it also presents a potential hazard. When pollutants from the attached garage seep into your home, they pose a real risk to your family's health. Pollutants come from sources such as:
  • Vehicles – Letting a vehicle idle in the garage even for less than a minute contaminates the air with fuel combustion gases, benzene fumes and fumes from other fluids.
  • Fuel-burning equipment – Equipment such as gas lawnmowers, gas hedge trimmers and gas or propane barbecues are also potential sources of pollutants from the attached garage. Running one of these in the garage for just a few seconds allows hazardous fumes to build up.
  • Stored chemicals – Fertilizers, pesticides, paint thinner, pool chemicals, and containers of fuel such as gas and kerosene all emit harmful fumes when not stored properly.
With a few basic steps, you can minimize the risk of garage air contaminants entering your Dallas-Fort Worth area home.
  • Control pollutants – Never allow a vehicle or any fuel-burning equipment to idle or run in the garage. Ensure all chemicals are kept in well-sealed containers designed for storing hazardous material.
  • Seal pollutant entry points – Pollutants can enter your home through air leaks in the wall between the garage and your home's interior. Openings for electrical wiring and pipes are common spots for leaks. Seal smaller leaks with caulk and larger holes with expanding foam spray.
  • Install an exhaust fan -- A garage exhaust fan, such as the type used in bathrooms and kitchens, helps vent contaminated air outdoors. It also increases the likelihood that air flows from the home into the garage, to equalize pressure, rather than the other way around.
These precautions, along with proper home ventilation, can help, but there's always a small chance dangerous fumes could leak into your home. To stay safe, install carbon monoxide (CO) detectors in your home and the garage. If you heat with a fuel-burning furnace, CO detectors are a must.

For more professional advice on controlling pollutants from the attached garage, sealing air leaks, and otherwise improving your home's safety and comfort, please contact us at Crawford Services Inc. Throughout Dallas-Fort Worth and North Texas, our knowledgable technicians provide service you can rely on.

Cheap And Easy Ways To Lower Your Heating Bills

Monday 25 May 2015 23:18
Written by

timetocutcostsWe may enjoy mild weather for most of the winter, but when those chilly winds and freezing rains do hit, the low temperatures can really run up the heating bills. Installing a high-efficiency furnace or heat pump is one of the most effective ways to cut heating costs, but there are also a few simple, low-cost home improvement jobs that will help keep your Dallas-Fort Worth home warm and do it affordably.
  • Seal air leaks – Air leaks waste heated air and cause uncomfortable drafts. To identify leaks, hold a lit incense stick or smoke pen up to leak-prone areas on a breezy day. These areas include window and door frames, baseboards, and penetrations for wiring, plumbing and vents. You can seal many of these leaks yourself using weatherstripping, caulk or expanding spray foam. For optimal air sealing, consult a professional who has the equipment needed to detect all points of air leakage.
  • Boost ductwork efficiency – In the typical home with forced-air heating and cooling, the ductwork wastes around 30 percent of the air it carries. Take a look at the ductwork in your attic and crawl spaces. Are the duct joints properly aligned, secured with sheet metal screws (or bands for flex-duct), and sealed with mastic? If not, thorough duct sealing could go a long way toward keeping your Dallas-Fort Worth home warm for less.
  • Improve your insulation – In our mild climate, it's not uncommon to find homes with too little insulation. In North Texas, the minimum recommended level of attic insulation is R38, which is around 12 inches of fiberglass batt insulation or slightly less cellulose insulation. If your attic insulation doesn't measure up, consider upgrading your insulation.
While you can do some of these jobs yourself, consulting a pro for a home energy audit will help you more accurately detect energy-loss issues and correct them in the most cost-effective way. Keep in mind these improvements also will help you reduce your cooling costs.

Furnace Troubleshooting Tips From Your Dallas Heating Repair Experts

Monday 25 May 2015 23:15
Written by

2_5_13If the furnace in your Dallas-Fort Worth home starts acting up, it doesn't always mean an emergency service call is in order. While some malfunctions and furnace noises indicate serious trouble, the most common furnace problems have simple solutions. Before calling your Dallas heating repair service technicians, try these furnace troubleshooting tips.

  • The filter – A clogged HVAC air filter can reduce air output and eventually shut down the furnace altogether. Remove the filter and hold it up to the light. If you can't see light through the filter, it should be replaced. Carefully replace the filter and turn on the furnace again to see if the simple filter replacement does the trick.
  • The thermostat – Reset your thermostat by turning it down a few degrees, then turning it up 5 degrees higher than the original temperature. Wait a few minutes for the furnace to re-engage and light.
  • The power supply – Look for the furnace's power switch, usually found beside or inside the furnace cabinet. It should be set to "on." Also check for a tripped circuit breaker or blown fuse.
  • The fuel supply – The gas valve should be open, with the handle in line with the gas pipe. With an oil or propane furnace, check that your tank isn't out of fuel.
  • The ignition – If the furnace in your Dallas-Fort Worth home has a pilot light, make sure it's lit. If your furnace uses an electronic ignition, which is the case with newer models, reset the ignition controller by turning the furnace power switch off and back on or by lowering, then raising the thermostat. Then listen for the spark or watch the hot surface igniter for a yellow-orange glow.
  • The exhaust pipe – Inspect the outdoor exhaust pipe for any snow, leaves or debris that may be blocking the airflow.
  • The motor – An overloaded blower motor will stop working until reset. Near the motor’s housing you'll find a reset button. If nothing happens when you press it, wait half an hour for the motor to cool and try again.


If these solutions don't correct the problem, contact your Dallas heating repair experts at Crawford Services. Wherever you are in North Texas, our knowledgeable, reliable technicians can help.

Efficient Heating and Air Conditioning in Dallas Requires Proper Duct Sealing

Monday 25 May 2015 23:13
Written by

03_07_13Heating and air conditioning Dallas style places a greater emphasis on cooling, but the need for an efficient ductwork system in your home is the same no matter the season. The ductwork is the series of large pipes that channels heated or cooled air from your furnace or air conditioner. Leaky HVAC ducts can account for substantial losses of conditioned air and wasted money every month. To keep your heating and air conditioning system working as efficiently as possible, it's necessary to properly seal the ductwork in your home.

You may have a significant leak in your ductwork if you've noticed one or more of the following symptoms:
  • Unexpectedly high heating or cooling bills
  • Inconsistent heating or cooling, or rooms with unusual conditions such as stuffiness or large amounts of airborne dust and particulates
  • Difficulty maintaining consistent and appropriate levels of heating or cooling in particular rooms or areas of the house
  • Ducts that are visibly damaged, loose, detached or missing
  • Un-insulated or poorly insulated ducts in unconditioned areas of your home, such as crawl spaces, unfinished basements and attics or garages
Leaky ductwork can also be dangerous if carbon monoxide or other harmful exhaust gases escape into your home. That's why it's important to have your system assessed regularly by a heating and air conditioning Dallas professional.

A ductwork sealing project should include the following:
  • Check the entire length of the ductwork system for potential leaks or other problems.
  • Repair or replace any damaged ductwork sections.
  • Reconnect loose sections and make sure they fit together tightly.
  • Straighten any bent or kinked ducts.
  • Seal holes, cracks or openings in the ductwork.
  • Ensure secure duct connections at registers and vents and at the HVAC unit.
  • Make sure all connections and joints are sealed with mastic, a specialized sealant for use on ducts, or with metal tape.
  • Avoid using standard duct tape; the adhesive can fail over time.
  • Insulate ductwork with rigid fiber board or standard roll insulation. This helps prevent energy loss through the metal of the ductwork itself.
Crawford Services, Inc. can provide a full range of HVAC work that produces the results that heating and air conditioning Dallas customers can rely on. Contact us today for more information on the benefits of duct sealing or to schedule a professional duct evaluation and sealing.

Is Your Central Heating Ready: A Fall Tune Up Can Help you Save Money

Monday 25 May 2015 23:08
Written by

Your central heating has probably been the last thing on your mind here in Dallas over the last couple of weeks. But, now is the time to take a look at it and make sure it is in the right condition to start up for winter when the cold pours in. The last thing you want is for the temperature to drop and your central heating not to work like it is supposed to.

Your central heating is a mechanical and electrical marvel. It is one of the things that define the era you live in. Just 50-60 years ago, rooms were heated and cooled separately. So, give your HVAC system the respect it deserves. That means realizing that it has been sleeping for several months now and when you flip that switch to wake it up, it might be grouchy. Be prepared to deal with a few sudden outbursts of groggy clinging, dusty coughing and rotten smells.

03_07_13You have probably noticed in the past when you have woken your central heating up from its hibernation that rusty, burning smell. Well, in most cases that is normal. It is just rustling up the dust and tiny debris that have settled in there and it is basically burning it off. Some industry professionals refer to this as “fall breath.” But, that is just a good indication that you need to treat it like the delicate machine it is.

Let’s take a look at a few of things you need to do to tune that sleepy giant up before winter:1.      First of all, pay close attention to the thermostat. Do you normally set it to the same temperature in the winter as you do in the summer? No, of course not. Go ahead and reset it to the winter normal temperature so that your central heating will have a reason to kick on. As a matter of fact turn it up a little bit higher in case you are doing this when it is still a little warmer out.

2.      Open your control panel to your furnace and check to make sure it is working properly. It is a good idea to have all the dust and cobwebs cleared away from this beforehand so that you do not risk electrical shock. You need to look for things like the starting cycle. Does it start up okay? Is it operating without any discrepancies? Is it shutting off properly when it reaches the thermostat temperature?

3.      Take a look at your gas connections. Do you smell any leaks? Do any of the connections look like they need to be replaced? You should also have a professional look at these and tell you if the gas pressure, burner combustion and heat exchanger are in safe working order.

4.      Your central heating is composed of moving mechanical parts. Just like anything mechanical, it needs grease. Go through and check all moving parts and give it a fall lube. This is also something that you might need to refer to a professional, especially if you are not knowledgeable about HVAC systems and components.

5.      Inspect your electrical connections and make sure they are in safe and proper working order. Your central heating system relies on electrical connections to work properly and if any of them are frayed or loose, that can lead to problems that you definitely don’t want.

These are all things that should be taken care of well before the winter weather starts creeping in, but it is highly advisable to call a professional out to your Dallas home to handle these tasks. Your central heating system is a complex and delicate machine. If you are unsure of what you are looking at or doing, then you can easily damage it.

Many of the things you can do to help maintain your central heating and entire HVAC system are standard pre-emptive measures. This includes checking and cleaning your condensate drip line, routinely changing out your air filter and keeping furniture as well as other household items away from your vents.

All three of those things are factors that contribute to your HVAC system having to work harder to distribute the produced air. The basic principle here is to make sure that all working parts are obstruction free.

The key to having and using a healthy central heating system is maintaining it. In most cases, it is the little things that add up to make sure it lasts a very long time. Now is the time to wake up your heat and get all the kinks out before cooler weather comes knocking on your door.

Boiler Repair: How to Ensure That You Stay Warm this Winter

Monday 25 May 2015 23:02
Written by

Boiler repair can be avoided with regular maintenance-- keeping your boiler running efficiently is a little like keeping your car running efficiently, regular servicing is the answer. Just as with your car,a regularly maintained boiler will save you money in the long run and not let you down when you need it the most. You should make sure that your boiler is regularly maintained to avoid the need for costly repairs. At the very least, an annual checkup is required to ensure that your home stays toasty during the cold winter months.04_04_13

So what does a boiler do and what are some of the common problems to be on the lookout for? If you notice any of these problems, then it’s time to call in a specialist in boiler repair – it may even be too late and replacement could be the only answer.

• Lack of heat and hot water. The main function of a boiler is to heat your home and heat your water. If you have neither, then you know there is trouble. This trouble may be elevated to Trouble (with a capital “T”) in the winter months.

• Drips and leaks are a sure sign that something is happening with your boiler that really shouldn’t be happening. The severity and cause of the problem depends upon where the drips and leaks are actually coming from.

• Strange noises, banging, gurgling, whistling, and things that go “bump” in the night. This could be caused by any number of issues, such as air in the system or a sign that the water pressure is far too low.

• Losing water pressure. If your usual high water pressure is reduced to a trickle, this could also point to boiler problems. Perhaps your boiler needs a replacement pressure relief valve. You’ll want to call in the boiler repair professionals as soon as you notice this type ofproblem.

• Thermostat related problems. Maybe your thermostat appears to have “lost its way” and switches on or off when you don’t want it to, or it simply ignores the temperature controls you have in place and leaves you sweltering one minute and freezing the next. Investing in anew thermostat with increased energy efficiency can save you money and hassle.

• Boiler switching off when it’s not supposed to. This could be because of low water pressure or a faulty valve, problems with the circulatory air pump, thermostat problems – there are a whole heap of possibilities here.

• Heaters not heating up. This could be because of corroded pipe work, air in the system, sludge, or something else preventing the hot water to flow freely around the home. Your system may need to be chemically cleaned and flushed by the professionals.

If you notice any of these boiler problems then a boiler repair professional should be called to your home as soon as possible.

So, what are some other things do you need to look out for while you’re on “boiler alert?” It can be pretty cold and miserable to live in a house without hot water or heat during the winter, even if it’s only for a few short days--that is, if you have the necessary funds to pay for your boiler repair. You can bet your bottom dollar that your boiler will give up the ghost when the temperature and your bank balance are at their lowest.

The only sensible solution to this problem is to be pro-active. It’s been said before and it will be said again, regular boiler maintenance is the best, most cost-effective method of keeping your boiler running all year round.

Here are a few other signs which could point to the fact that your boiler is in desperate need of a service.

Old age takes its toll on many things – people, cars, houses, pets, and boilers. Boilers have an average life expectancy of around 15 years, so if your old faithful is heading into the twilight zone, then it could be time to go shopping. If you wait until your boiler goes BANG you won’t have the necessary time to shop around for the best deal. If your old boiler uses a pilot light for starting the burner then you can be pretty sure that it’s at least 25 years old.

Rising heating bills are another sure sign that a little boiler repair is called for. As boilers get older they lose efficiency which means increased heating bills. Regular maintenance can help your boiler to run at its peak and save you valuable dollars.

If your house has “hot spots” and “cold spots” it could be another sign that the boiler is in need of repair or replacement. Efficient heating systems disperse the heat equally to coincide with the setting on the thermostat. You should be able to set it and forget it (and stay warm and comfortable).

Just like cars, once old boilers start to break down in one area you can be pretty sure that the whole thing is getting worn and unreliable. If your boiler breaks down every winter, even after an annual service then you should seriously start to consider searching for a new solution to your heating and hot water problems.

One last but very important issue about inefficient boilers is not only the comfort of your family but also their health. Boiler repair is essential for the safety of your family. Badly maintained boilers can develop leaks of carbon monoxide which can quickly prove fatal for the entire household.Carbon monoxide is colorless, tasteless, you can’t smell it, you won’t even know it’s there . . .it is also deadly. Leaks can cause queasiness, headaches, flu-like symptoms, disorientation, and burning sensation in the nose or eyes. If you, or any member of your family, suffer from any of these symptoms, open the windows to ventilate your home and call the boiler repair service as soon as possible.

Dallas Duct Cleaning — Understand When It Needs To Be Done

Monday 25 May 2015 22:58
Written by

If your Dallas home’s air ducts have never been cleaned, you probably don’t even realize the immediate benefits you will get once it’s done. Duct cleaning can have a huge impact on your indoor air quality but because they get dirty over time, you often don’t realize when you need to clean them. While it’s good to have air ducts cleaned every few years, a few tell-tale signs will signal that you should have it done immediately.

Mold GrowthLook inside your air ducts (be sure to turn your air system off first). If you see mold growing on the metal inside, they’re in definite need of a cleaning. Mold spores can detach and start to circulate throughout your house with the aid of your air system. This is a major respiratory irritant and can cause severe health problems.

RodentsIf you have had problems with rodents or insects in your ducts, you need to have them professionally removed. Once you’re sure the problem is taken care of, have your ducts cleaned so that no remnants of them can get in your home’s air.

Excess DirtYour air filters do most of the work when capturing particles from the air but if your ducts are dirty, even they won’t be able to help. If you can actually see dust coming from the supply registers as conditioned air enters your home, you know it’s time for a duct cleaning.

The Telltale Signs Of HVAC Ductwork Problems

Monday 25 May 2015 22:54
Written by

HVAC ductwork problems can go unnoticed for a long time, but the efficiency of an air delivery system directly influences the performance of your air conditioner, furnace or heat pump. You may be losing as much as 30 percent of your conditioned air as a result of faulty or leaky ducts, according to the U.S. Department of Energy.The ductwork in an HVAC system consists of a long, branching group of duct pipes that snake throughout your home, hidden behind walls, in ceilings and floors, or in the attic. Because the majority of the HVAC system is hidden, homeowners often have a hard time determining ductwork’s condition. And over time, connections can loosen or ducts can incur damage.

Most often, ductwork problems require the help of a professional, but here are a few problems you can self-diagnose on your HVAC system.

Uninsulated ducts


When a portion of your HVAC system travels through areas that don’t have access to cooled (or heated) air, like your garage or attic, cool air moving through the ducts will succumb to the hotter attic air surrounding the duct pipes. In the winter, heated air can cool off for the same reason. This is easily fixed by insulating ducts.

Damaged ducts


A variety of factors can lead to damaged ducts, such as connections breaking lose, human interference or poor installation. If conditioned air leaks out of the ducts, you’ll pay for it in terms of higher energy costs. Seriously damaged ducts may require that you replace a portion of the HVAC ductwork system.

An efficient HVAC ductwork system relies on a balanced supply of air sent into your home, along with a healthy amount of return air that moves back into your HVAC equipment. The return-air portion of ductwork is particularly prone to problems such as a lack of adequate return grilles, and the system is prone to leakage too. Proper inspection will identify the root of ductwork problems.

There must be an equal amount of return air to support the supply air ducts. For every ton of air conditioning capacity there must be 400 cubic feet per minute of air volume available in both return air duct and supply air.

Air Conditioning Specialists Offer 5 Tips for Easy A/C Maintenance

Monday 25 May 2015 22:52
Written by

 05_15_13Air conditioning specialists recommend regular preventive maintenance as the best way to keep your home cooling system working at its best possible level. The same as any other cooling or heating system in your home, a properly maintained A/C will operate more efficiently and reliably, with more even cooling, superior humidity control and a longer service life, all with lower operating costs.Here are five easy ways to maintain your home air conditioner's performance and efficiency this cooling season.

  1. Change the air filter: Clean filters ensure proper airflow and effective filtration of your indoor air. Air conditioning specialists report that dirty air filters are a major source of air conditioner breakdowns because they block needed airflow. Check the filters in your air conditioning system at least once a month and change them if they are dirty.
  2. Clean the unit: Remove any accumulated material from the outdoor cabinet, such as leaves, grass, sticks or nests. Keep the vents clear of vegetation and other material. Wipe down the cabinet or spray it clean with a garden hose. Apply a light coat of automotive wax to the cabinet's outside surfaces to protect them from sun and the elements. Make sure your lawn sprinkler does not spray the cabinet directly.
  3. Trim vegetation: Trim vegetation around the outside unit, including grass, tree limbs, shrubs or any other plants that could block airflow. Allow at least two feet of clearance on all sides of the air conditioner's outdoor unit.
  4. Clear indoor air vents and registers: Check indoor vents and registers to make sure they are unobstructed and clear of boxes, clothing, furniture or other items. If supply vents are blocked, cool air from the A/C unit cannot get into your home. If return vents are blocked, airflow is hindered and the unit will not be able to get enough expended air back for recooling.
  5. Schedule preventive maintenance: Contact your local trusted HVAC service provider to have your air conditioner inspected and maintained at least annually, preferably before the start of the cooling season. These appointments allow trained air conditioning specialists the opportunity to check out your home cooling system, make adjustments and correct minor problems.

Your Dallas HVAC Contractor Can Tell You About The Benefits of Zoning Systems

Monday 25 May 2015 22:48
Written by

04_24_13A Dallas HVAC contractor has a tough job. Our North Texas weather is usually either too hot and humid or too cold and dry for comfort, so it takes exceptional know-how to design a system that provides comfort year round. One of the most effective ways an HVAC expert can achieve this goal is with a zoning system.

Most homes have just one thermostat that controls the temperature throughout the house. This usually leaves some areas too hot or cold. With a zoning system, you'll have more precise control over temperatures in separate parts of your home.

The system is based on programmable thermostats in each zone and dampers inside your air ducts. The thermostats allow you to independently control temperatures in two to four zones in your home.

The dampers direct airflow based on the selected temperatures. They send conditioned air in your ducts away from zones that need less heating or cooling and toward zones that need more. Your trusted Dallas HVAC contractor can help you define your zones and choose your ideal temperatures.

Among the benefits you'll see from zoning:

Greater comfort – With a zoned system, you'll no longer have to put up with uncomfortable temperatures in certain parts of your home.

Energy savings – Programmable thermostats provide an easy way to limit heating and cooling in parts of the house that are unoccupied at certain times. For instance, you may decide not to condition your bedroom for most of the day. You'll no longer waste money over-heating or cooling one area just to get a comfortable temperature in another.

No more thermostat battles – Instead of trying to find one temperature that pleases everyone, with zoning you can ensure everyone has a part of the house where they feel comfortable.

While some homes won't benefit much from zoning, others are ideal candidates. These include:

Multi-story or sprawling homes – Multi-story homes can be hard to heat evenly because hot air rises. The upper stories often become overheated even when the lower levels are chilly. Even single-story homes are hard to condition consistently when they've got a lot of square footage.

Homes with unused spaces – These could be bedrooms you rarely enter during the day or spare rooms you keep closed for months at a time.

Homes with large areas of glass – This includes rooms with large windows or glass doors as well as solariums, atriums and other large glass-enclosed spaces. Because glass is a poor insulator, these areas need special temperature control.

If you're tired of inconsistent temperatures, an experienced Dallas HVAC contractor can help you find a solution. To get started contact us at Crawford Services. We provide friendly, cost-effective services in the Dallas area.

Dallas Heating Bills Can Be Reduced With Proper Programmable Thermostat Settings

Monday 25 May 2015 22:45
Written by cc04_30_13Dallas heating may not be the most expensive in the country, but our chilly North Texas winters can still run up the bills. One easy, inexpensive way to keep those bills down is with a programmable thermostat.

Programmable thermostats let you define a pre-set schedule for your heating and air conditioning. They provide a convenient way to manage your heating and cooling for energy savings.

Turn your heat down by seven to 10 degrees for at least eight hours a day and you can reduce your yearly heating bill by 5 to 15 percent. You'll see a savings of up to 1 percent for each degree you lower the thermostat for eight hours a day. A Dallas heating expert can help you choose temperatures for optimal comfort and savings.

For the greatest savings, there are a few guidelines you'll want to follow.

Choose long energy-saving periods – You'll see the greatest savings if you choose energy-saving set-points that are at least eight hours apart. For example, you might choose a lower temperature for the eight-hour period when you're in bed or away at work. Contrary to what many assume, letting the house get cold doesn't force your furnace to work harder than normal to raise the temperature again.

Avoid frequent overrides – The override modes on your thermostat let you temporarily change your thermostat setting without changing the pre-set programming. While there are appropriate times to use the override feature, you'll run up higher heating bills if you frequently override your energy-saving settings.

Use the right override – "Temporary" and "hold/permanent" are the two override modes found on most programmable thermostats. "Temporary" mode changes the temperature only until the next pre-programmed period. This mode should be used for short-term adjustments, such as unexpectedly cold days. "Hold/permanent" maintains your chosen temperature until you cancel the override. This mode is appropriate for times when you're away for two or more days, such as a vacation.

Pick moderate temperatures – Setting your thermostat to 80 degrees doesn't heat your home quickly. It only wastes energy. For comfortable Dallas heating and energy savings, you might choose 68 degrees for times you're home and awake, then program your thermostat for seven to 10 degrees lower for the times you're in bed or away. For more precise control over your home's temperature at specific times, choose a thermostat with adaptive recovery technology. These models calculate the amount of time needed to reach the pre-set temperature, then run the furnace so your home reaches that temperature by the programmed time.

If you're interested in installing a programmable thermostat or any other energy-efficient HVAC equipment, contact us at Crawford Services. In the Dallas area, we provide reliable, cost-effective HVAC care.

A/C Installation Service: What You Can Expect In The McKinney Area

Monday 25 May 2015 22:40
Written by

06_20_13

A/C installation service is an important element of air conditioner performance, but it's often overlooked or, in the worst cases, neglected. No matter how efficient the equipment itself is, a poorly installed system cannot function at top level and keep your home comfortable. Here are some of the things that HVAC customers in the McKinney area should expect from professional, expert air conditioner installation.

Proper A/C installation service

Proper A/C installation service takes into consideration the type of equipment you've purchased, its rated efficiency level, how the unit operates, and how it should be placed and configured to work at its best. A well-installed air conditioning system will operate reliably for an extended period with only the usual preventive maintenance and annual tune-ups.

It is certainly possible that you could install your new air conditioning system yourself. You may also find non-credentialed installers who charge lower rates. However, it's always best to leave air conditioner installation to trained and qualified professionals. They know what proper A/C installation service requires and have access to the tools, materials and testing devices that ensure safe and correct equipment operation.

Installation factors

Proper A/C installation service should include the following factors:
  • Proper calibration of controls and system components. The entire system should be tested to make sure it's operating properly and according to expectations.
  • Correct refrigerant charge according to manufacturer's specifications.
  • Correct placement of condensing unit and ductwork to avoid problems such as noise or energy loss.
  • Correct installation of thermostat to avoid incorrect readings of indoor temperatures.
  • Correct duct size and configuration for the best air distribution efficiency, with ducts sized according to industry-standard sources such as the Air Conditioning Contractors of America (ACCA) Manual D, covering duct design and sizing.
  • Installation of enough supply ducts to properly distribute cooled air and enough return ducts to bring expended warm air back to the unit.
Crawford Services, Inc. provides top-quality cooling and heating services for customers in the Dallas area. Please contact us today for more information on the importance of proper A/C installation service or to schedule a professional installation for new home cooling equipment.

Switching To Geothermal Worth The Look Thanks to Federal Tax Credits

Monday 25 May 2015 22:38
Written by

Geothermal heating and cooling systems are much more efficient than standard HVAC systems and can help you save money. It’s especially true if you live in North Texas. You already know summer brings extreme heat and winter can have long periods of freezing weather. This can jack up your heating and cooling bills something fierce.f93e4a78-c2e7-4273-c2d0-e8b19195674d

Unlike most heat pumps, geothermal heating and cooling systems use the earth as a conduit to cool or heat a closed loop water system. This, in turn, runs your home’s AC, heating, and hot water bypass. These systems are 45 percent more energy efficient than other options in the marketplace today. Because of this, the government is offering a 30 percent federal tax credit for anyone who installs a new geothermal system in their home.

The 30 percent federal tax credit will cover the cost of the new unit, plus the costs of all installation and labor. To be eligible for the credit, you have to have a new geothermal heating and cooling system installed in the home you live in. It’s not available for any systems placed in rentals or secondary vacation homes. The new heating and cooling system must meet the Energy Star requirements that are in effect at the time the system is purchased.

Currently, heat pumps that are certified by the unit’s manufacturer are eligible for the tax credit and should be installed by a licensed contractor. It is important to have an engineered system for your specific home needs.>34e6cec2-2b00-48d3-f703-e2240722a8023

While a geothermal system may require a larger upfront investment than regular HVAC systems, they will pay for themselves with the utility savings over the years. Plus, a system lasts up to four times longer than a standard conventional AC system, which saves even more money the first time you don’t have to replace the AC equipment.

Options For Geothermal Ground Loop Installations

Monday 25 May 2015 22:31
Written by

Geothermal heat pumps use the constant temperature of the ground to exchange heat between the inside and outside of your house. It pulls heat from the ground to heat your home in the winter, and pulls heat from your house and leaves it in the ground in summer.

A geothermal system can reach efficiencies of up to 600 percent. Compare that to even the most energy efficient furnace, which can't convert all of its energy into heat for your home. Air source heat pumps typically achieve heating efficiencies of up to 250 percent, though that’s still far less than a geothermal heat pump.

The primary component of a geothermal heat pump system is the ground loop, which is either open or closed. In a closed loop system, the pipe typically runs horizontally, between 4 and 6 feet deep, or vertically between 100 and 400 feet. In North Texas the average depth required for a good heat transfer is 250 feet per well loop. The pipes are filled with an environmentally safe antifreeze and water solution that acts as a heat exchanger. In the less-common open loop system, surface water is used as a heat transfer medium.

When considering your options for geothermal installations, it’s important to factor in your location. Your property type will determine which type of ground loop you'll use. Your geothermal HVAC contractor will look at the geology, hydrology and landscape to decide.

The composition of your soil and rock affects the rate at which heat is transferred. For example, soil with good heat transfer properties will require less piping. Areas with shallow soil or lots of rock may require vertical ground loops.

The availability of ground or surface water can help determine what type of ground loop to use. Certain bodies of surface water can be used as a source of water for an open-loop system, or in a closed-loop system as the location for coils of piping. Ground water can also be used as a water source for open-loop systems, provided the water quality is suitable.

Seasonal Geothermal Maintenance Is Essential To Year Round Comfort And Efficiency

Monday 25 May 2015 22:30
Written by

Has your geothermal heat pump system gotten its yearly maintenance check? Even though it's a "heat pump," it's already working hard this summer. But if you missed your regular springtime maintenance call, you don't want the thing to struggle and overwork itself trying to keep your house cool. Geothermal systems are capable of cooling (and heating) your home very efficiently. They transfer heat energy into the ground rather than burning fuel. Geothermal heat pumps use the earth’s constant temperature to exchange heat between your home’s interior and the outside. The primary component of a geothermal system is the ground loop, which is either open or closed. In a closed loop system, the pipe is typically between 4 and 6 feet deep and horizontally, or vertically at a depth of between 100 and 400 feet. The pipes are filled with an environmentally safe antifreeze and water solution that acts as a heat exchanger. In the less-common open loop system, surface water is used as a heat transfer medium.

Seasonal geothermal maintenance



This heat extraction and release process repeats until your home is cool. To stay cool, it’s wise to call in a heating and cooling pro twice a year at the start of the cooling and heating seasons. The technician will ensure proper airflow, mechanical function, and system performance by the following methods:
  • Thoroughly clean the indoor and outdoor units. This includes removing dirt build-up and blockages that consistently occur at the heat-exchanger coils and blowers.
  • Measure blower air speed. Airflow that’s too slow reduces heat exchange efficiency. Airflow that’s too fast wastes electricity, and produces more noise than necessary.
  • Electrical components are inspected for function, tight connections and wear and tear.
  • All moving parts are lubricated.
  • The system is checked for leaks. If there are leaks, the technician will discuss repair options with you.
  • Once the geothermal system is clean, airflow optimized, and no refrigerant leaks are detected, accurate refrigerant levels may be measured.

Geothermal Cooling And Heating — Year Round Comfort And Savings

Monday 25 May 2015 22:26
Written by

Geothermal cooling and heating provides North Texas homeowners with an extremely efficient and money-saving method of maintaining home comfort in all seasons. Heat pumps can attain astonishingly high levels of efficiency (300 to 600 percent, in some cases) while producing no greenhouse gases or other harmful emissions. Geothermal units are clean and quiet and can save homeowners up to 70 percent on their seasonal heating and cooling bills.

Heat pumps achieve these high-quality results through their unique mode of operation. In general, geothermal heat pumps operate much the same as a traditional heat pump. Both use water or a compressed, high-pressure liquid coolant to capture heat and move it either into or out of your home to maintain seasonally appropriate temperatures. While a conventional heat pump uses heat from the air, a geothermal model uses heat generated naturally below the surface of the ground or a body of water.

A few feet under the ground, temperatures are always about a consistently mild temperature, somewhere around 50 – 60 degrees, no matter what the temperature is on the surface. Geothermal heat pumps move and exchange heat through a series of pipes buried in the ground at this consistent-temperature depth. These units do not have to work harder to extract heat from cold outside air, which can cause air-source systems to use more electricity. Instead, they shift heat back and forth from a source that stays about the same temperature all the time. This leads to highly efficient operation, better levels of indoor comfort and reduced power consumption.

Geothermal systems require more of an upfront investment versus conventional air conditioning systems. There are three main areas of savings where home owners will quickly recoup this investment and then begin to see a positive payback:
  • A 30% tax credit on the initial installation.
  • Up to 70% savings annually on utility bills required to operate your AC system.
  • Geothermal heat pumps last up to 3 times longer than conventional equipment, because the equipment is indoors instead of outside, and is not subject to the outdoor elements and have ideal operating conditions with little stress on the equipment.
However, they can be as much as 50 percent more efficient than even high-efficiency heating and cooling systems. The dramatically increased efficiency and comfort they provide can make the investment in geothermal cooling and heating a wise long-term option.

Your Geothermal System And Ceiling Fans: A Dynamic Duo

Monday 25 May 2015 22:24
Written by

You know your geothermal system can keep you cool in the summer and warm in the winter. And you've got your ceiling fans running every summer to help keep the temperature down. But did you know that you can use ceiling fans to your advantage in the winter as well?

Many people avoid using ceiling fans when the temperature drops outside because of the cool breeze they create. But, just reverse the direction the blades spin — clockwise, instead of counterclockwise — it creates an updraft that sends warm air from the geothermal system that has collected near the ceiling back down into the living space, and helps your geothermal system work more efficiently.

It’s important to keep the fan spinning on the lowest setting in the winter so the updraft moves slowly. Otherwise, it could create cooling air movement that would defeat the fan’s usefulness for geothermal home heating.

Homes with vaulted ceilings or open stairways benefit the most from ceiling fans in the winter. Since hot air naturally rises, homes with lots of open space overhead experience uneven heating and higher energy bills. The updraft from a fan on a vaulted ceiling sends warm air back down to the edges of the room.

Install a ceiling fan at the top of an open stairway to help mix the air more evenly. It keeps the upper story from becoming overly warm. Even if you don’t have vaulted ceilings or open stairways, ceiling fans can still reduce your geothermal heating costs and help decrease condensation buildup on window panes that can lead to moisture damage.

Running a ceiling fan costs mere pennies per day — even less if you choose an Energy Star rated fan. Installing and using ceiling fans properly in your home can help you save up to 10 percent on your heating bills while helping your home feel more comfortable as well.

Geothermal Heat Pump Buying Guide

Monday 25 May 2015 22:21
Written by

Geothermal heat pumps, refrigerators, and air conditioners have one thing in common: they remove heat from one place and transfer it to a different place. Geothermal heat pumps let you control the temperature in your home year-round, because the cycle is reversible — you can take heat out of your house in the summer, and put it into the ground or a standing water supply, like a pond. Or you can take the heat out of the ground in the winter, and have it transferred into your home.

When installed correctly, geothermal heat pumps can deliver two to four times more heat to a home than the actual energy they use to operate, which makes them very efficient. Overall benefits include:
  • Decreased utility bills (25 to 70 percent less than conventional HVAC systems)
  • Less maintenance
  • Controlled climate, more comfort year-round
  • Lower emissions
Two main types of heat pumps are on the market today: air source and geothermal. Air source pumps take heat from an air source, whether inside your home or outside. A geothermal pump will draw its heat energy from a different source, whether the earth, ground water, or another water source.

Efficiency should be a top priority when you’re looking into purchasing a heat pump. Energy Star-labeled systems operate 8 to 20 percent more efficiently than traditional HVAC systems. However, the size of the system is a key factor in the final price.

Your system needs to be sized by an HVAC profession, but the general rule of thumb is you will need one "ton" of geothermal heat pump for every 400 square feet of home you want to serve. For example, if your home is 2,000 square feet, you will need a 5-ton heat pump. (This isn’t a ton in the traditional sense, but rather a term that originally referred to how much ice was needed to cool a certain amount of air.)

Tax Credits Are Another Benefit Of Geothermal Heat Pumps

Monday 25 May 2015 22:19
Written by

crawford_12_4_12Geothermal heat pumps may be the best way to condition homes in our climate. We have long, hot summers and periods throughout the winter that can be exceptionally cold. A geothermal system is capable of providing efficient conditioning for both extremes.

Instead of using the air to harvest or dispel heat, geothermal systems use underground resources, where temperatures are stable and moderate. So efficient are these systems that the federal government is offering a 30 percent tax credit for homeowners who install these systems before the end of 2016. This credit covers primary and secondary residences, although it does not extend to rental properties.

The primary reason the government is offering this credit is to help homeowners lower their energy consumption and offset the higher installation costs of these systems. Geothermal heat pumps use up to 60 percent less energy to run than air-source heat pumps, which is why the tax credit is so generous. A heat pump in our region is an efficient HVAC appliance, but when the pump can use stable underground resources rather than volatile air temperatures, this appliance offers even better energy savings.

Not only does a geothermal system provide excellent energy efficiency, it's also a durable heat pump. The underground loop can last up to 50 years or more and the indoor air handler up to 25, with routine maintenance. Geothermal systems also do not have exterior condensers, which frees up yard space and eliminates the noise in your yard.

In order to qualify for the tax credit, the geothermal heat pump has to have earned the Energy Star designation. There is no upper limit on the amount that can be claimed for either the cost of the equipment or its installation. The tax credit may not cover adjustments to your ducts, however, unless the adjustments impact the overall energy efficiency of the system.

Geothermal Heating and Cooling in Dallas – Is It Right for You?

Monday 25 May 2015 22:17
Written by

02_26_13A geothermal heating and cooling system is an extremely efficient and economical alternative to traditional natural gas powered or electric powered furnaces /air handlers and air conditioners. When evaluating the merits of the many available types of geothermal heating and cooling in Dallas, keep in mind the following benefits you'll enjoy with a geothermal comfort system.
  • Exceptional efficiency: Geothermal systems are extremely efficient, providing an extraordinary 300 to 400 percent efficiency level. They produce three or four units of heat for each unit of electricity consumed. This can be achieved because heat pumps do not generate heat. Instead, they capture and displace energy allowing the ground beneath us to serve as the energy source to cool or heat water which serves as the source of energy for the homes comfort system. Sounds confusing but it really is a simple process.
  • Flexibility: Geothermal heating and cooling is appropriate for any climate and can be adapted for use in most any setting, urban, suburban, or rural.
  • Low cost of operation: Geothermal heating and cooling systems can slash your monthly energy bills by as much as 70 percent. You will find that the initial investment in a geothermal installation system may cost up to 2 times the amount of a conventional system, but the 30% federal tax credit on the complete installation combined with the monthly savings on your utility bills means you'll recover the initial costs in 3-7 years depending on your total usage.
  • Lower lifetime costs: Geothermal heating and cooling systems are sturdy and reliable. With regularly scheduled, twice year maintenance, a geothermal heat pump system will last 25 years or longer. That is 2-3 times longer than a conventional furnace or condensing unit. Why? Because the geothermal system sit inside your home in a mechanical area that is not subjected to the outdoor elements and corrosive conditions. They need little maintenance and repair to keep them running.
  • Peace and quiet: Geothermal heat pumps produce very little noise when they operate. They work quietly and are not irritating or disruptive to your household. So there are no unsightly large condensing units lined outside your home or noisy while you are trying to enjoy the outdoors.
  • Environmentally friendly: Geothermal systems do not burn fuel, so they do not produce greenhouse gases or dangerous exhaust fumes such as carbon monoxide. Their efficiency level means they use less electricity than other sources, which reduces overall demand for power from your local electric company.

Geothermal Energy: Eco-Friendly, Consistent and Cost-Effective

Monday 25 May 2015 22:15
Written by

04_18_13Geothermal energy provides Dallas area homeowners with an efficient, cost effective and environmentally sound source of home heating and cooling.

A geothermal system takes advantage of the fact that the ground maintains remarkable temperature consistency, absorbing much of the solar energy from the sun’s rays as they hit the ground. A properly installed geothermal energy system uses a buried earth loop to convert this free energy into affordable and energy-efficient central heating and cooling.

In the heating cycle, the geothermal heat pump uses the earth loop (carrying a water/antifreeze mix) to extract collected solar heat from underground. After the system removes heat from the loop, it’s distributed into your home via your air ducts. For geothermal cooling, the heating process is reversed to create cool, conditioned air for the home. Instead of removing heat from the ground, heat is pulled from the air in your home and either returned to the earth loop and the ground, or used to preheat water in your storage water-heating tank.

Geothermal energy offers heating and cooling customers several very attractive benefits, including:
  • Extremely high efficiency: Geothermal heating systems can be highly efficient, often returning three or four units of heating per each unit of electricity consumed by the system. The fact that geothermal systems capture and move heat readily available underground (or underwater) rather than burning fuel to generate heat accounts for this type of efficiency.
  • Consistency and flexibility: Geothermal energy systems can be used in any climate and can be adapted for use in almost any residential setting, from urban to suburban to rural.
  • Low cost of operation: With geothermal heating and cooling, you can knock your monthly energy bills down by as much as 70 percent. Though geothermal can be expensive to install, the monthly savings alone can pay for the system by about the halfway point of its useful life span. Further reducing the costs, the federal government, through 2016, is offering a 30 percent energy tax credit for qualifying geothermal systems.
  • Environmentally friendly: Geothermal systems do not burn fuel to produce heat, so they do not produce greenhouse gases or harmful exhaust gases such as carbon monoxide. Because they are so energy efficient, they use less electricity, which reduces demand on your local utility company.
  • Inexpensive water. Geothermal heat pumps are often equipped with the ability to use warmth removed from your home in the summer for low-cost water heating.

With Geothermal Energy, Make Sure Your Heat Pump Works Well

Monday 25 May 2015 22:12
Written by

07_02_13Geothermal energy is a clean, efficient and economical source for residential cooling and heating. Keeping your geothermal heat pump working at its top level of performance requires regular maintenance and repair of problems as they occur. In cooperation with your geothermal specialist, you can take effective steps to keep your heat pump working like it should.

What you can do if a problem arises
  • Check the power supply. Make sure the heat pump is plugged in and receiving electrical power.
  • Check air filters and coils. Dirty filters and coils can cause problems with the system's airflow and head pressures. Clean the coils and change the air filters if they are dirty.
  • Look at temperature settings. Make sure the thermostat has been set to an appropriate temperature and mode (heating or cooling) for the season.
  • Check for physical problems. Carefully inspect the system for leaks, disconnected wiring or physical problems that could cause malfunctions.
What your geothermal energy systems expert can do

Your geothermal system professional has the necessary expertise and equipment to test for and repair technical issues. He will look for problems such as:
  • Reduced effectiveness and efficiency: Could be an issue with restricted system airflow. Check and change air filter.
  • No cooling: Cooling levels can be affected by low refrigerant charge, scale build-up in the heat exchanger, restricted metering devices, or a defective reversing valve. The system thermostat may need to be moved to another location so that it senses indoor temperature changes more accurately.
  • High indoor humidity: This could be caused by too much airflow or an oversized system. Your technician can adjust the fan motor speed to help resolve the problem.
  • Problems with the loop system. The use of geothermal energy for heating and cooling requires a functioning loop system where heat capture and release occurs in the ground (or water). Your technician will make sure the loop pumps are working properly and that there is appropriate pressure in the loop system.

A geothermal energy system provides exceptional cooling at a monthly cost that is usually much lower than other forms of cooling. The overall benefits of geothermal energy make it an attractive option for Dallas area home and business owners.

Basics of geothermal energy

Geothermal cooling and heating systems are based on heat pump technology. Instead of generating heating or cooling, the heat pump system captures heat and moves it in or out of your home. In a ground-source system, this is accomplished in a series of pipes buried in the ground at a depth where the temperature stays about 50-55 degrees all year long. Water-source systems are based on a similar concept, but the pipes are placed in a lake, pond, aquifer, or other body of water at a depth where the temperatures stay consistent.

A water/antifreeze solution (or in some cases refrigerant) flowing through the pipes is the medium of heat transfer. This solution either captures heat from inside your home and disperses it into the ground or water, which cools your home, or captures heat from the ground or water source and brings it into your home, where heat pump technology converts it into heating.

Installing a geothermal energy system requires careful consideration of the area where the underground or underwater pipes will be installed. For example, there must be enough ground space for the trenching and digging required to place the pipes. A horizontal system requires a wide flat area, while a vertical system requires deep holes for installing the heat transfer pipes.

Geothermal energy benefits

As a source of home cooling, a geothermal energy system provides multiple benefits that make it a good choice.
  • Very high efficiency: Geothermal heat pumps are extremely efficient, which means they provide indoor cooling at a lower price than other systems. Savings of 25 to 50 percent on monthly cooling bills are common. A geothermal system can often pay for itself in savings alone by about the halfway point of its expected lifespan. Plus, there's a 30 percent tax credit for qualifying geothermal systems.
  • Quiet operation: Geothermal cooling systems run very quietly compared to traditional heating and cooling systems.
  • Environmentally clean: Geothermal energy systems do not burn fuel, so they don't produce exhaust fumes or additional greenhouse gases. Their efficiency means they use less electricity than other systems, which reduces demand from local electricity suppliers.

Is Geothermal a Viable Option for North Texas Homeowners?

Monday 25 May 2015 17:17
Written by

Understanding geothermal heating and cooling is the key to deciding if it is the right option for you in your Dallas home. The first thing you need to know is that it is a renewable energy source. It still runs off electricity, but in a much more efficient way and the source of energy (heat) comes from the earth.

The layers of underground earth are typically between 54 and 67 degrees year round in north Texas. That temperature remains constant throughout the year because the ground actually absorbs nearly 50 percent of the sun’s energy. Geothermal heating and cooling taps into the energy stored underground and puts it to work for you in your home.

The first thing you need to consider is the impact geothermal has on the environment. A geothermal heating system has no emissio06_26_13ns, so there are no greenhouse gases that harm the environment coming out of it. It consists of a heat pump, plastic or copper lines buried under the ground, and of course your heating ducts. As a matter of fact, it is actually a very quiet system that will allow you to sit back and enjoy the natural ambient noise around your Dallas home. You might actually enjoy hearing the wind blow or the leaves fall. Maybe even hearing squirrels chirping and playing in the trees.

The earth’s heat powers a geothermal unit, but that does not mean it is only good for heating. Geothermal is fully capable of cooling your home as well, just as much as your old system does. When it comes to cooling, the system’s flow is simply reversed to achieve the cooling effect. We will talk more about that in a moment.

The information that is probably at the top of your mind right now is the energy savings, or how much money will it save you and how long will it last? Well, let’s just give you a little perspective on it first. For every dollar that you spend powering geothermal, the unit returns $4 dollars’ worth of heat. Old HVAC systems are usually about 94 percent efficient, but a geothermal system is 400 percent efficient. So you can expect to see a minimum of 30 percent savings, but more realistically, closer to 80 percent energy cost savings - and it will last for many generations to come.

Just keep in mind that the cost of installing a geothermal heating and cooling system is higher than traditional HVAC systems, but it will pay for itself in just a few years. Also, you will qualify for a 30 percent federal tax credit, in addition to state incentives. But, don't go trying to save money by installing geothermal yourself. In order for you to get the many years out of it you can expect, it needs to be installed correctly by a skilled professional that has experience in knowing where and how to lay the loop field. Otherwise, the system may not be able to harness the energy it was designed to produce.

Okay, now that we discussed the benefits of a geothermal system, let’s take a look at how it works. As we have already mentioned, the loop field, or heat exchanger, consists of several underground pipes that are either filled with water, antifreeze or a mix of both. These pipes are routed and buried through a system of underground loops, which absorb the heat. Depending on your location, the field can spread out horizontally or vertically. A skilled professional will have to make this call after he has taken everything else into consideration, including the blueprints of what is already down below the surface. The last thing he wants to do is hit a water pipe or a sewage line. Septic tanks can also heavily affect the layout of the loop field. But like we said, a skilled professional will know what to do in these situations.

Although you only need to go about five feet below the ground to reach the warmer geothermal temperatures, most contractors will go between 50 and 100 feet. In the case were there is an aquifer present, they will also make use of that as well, extracting the water then replacing it so nothing is consumed and everything is returned to the environment. But that is for a more complex, modified setup and we will stick to the basics here to help you understand.

Once the pipes are underground and the geothermal heat pump has been installed, as well as the air ducts, you are ready to fire up your system. During the winter when it is cold and you are trying to get the home comfortable, the water and antifreeze solution makes a constant loop through the field of pipes, pulling the cold air in your house with it, and returns back to your heat pump with a heated air temperature that has been absorbed and extracted from the ground. You might say that your home air is constantly traveling on a “comfortable temperature tour.” The heat pump then warms the air some more and circulates it throughout your home. This is where your energy bill kicks in, but the water in the loop field has done most of the heating so your heat pump does not have to work nearly as hard (you might even say 80 percent less).

But, when the summer months come along and it is time to cool the house, the geothermal system works in the same way, just in reverse. Basically, the hot outside temperatures will have heated your air enough so that when the air circulates into the loop field of pipes, the underground temperatures cool it down and loop it right back into your building. In most cases, 67 degrees is more than cool enough for the summer comfort.

To sum it all up, there is absolutely no down side to geothermal heating and cooling. It is better for the environment, better on your energy bill, it runs quietly, the government will give you a tax credit and the renewable energy source under your feet will never go away. With so many benefits and no repercussions, wouldn't it be worth it to find out more?

Is Geothermal The Right Choice for Your Home’s Cooling Needs?

Monday 25 May 2015 17:14
Written by

Geothermal energy is becoming increasingly popular, and for good reason. There are certainly many advantages to making the switch to a geothermal system for cooling your home. The air temperature around our homes may fluctuate with the seasons and the time of day, but the ground on which our homes stand stays remarkably constant throughout the year. It is these stable temperatures underground which can be harnessed to provide cooling, heating and hot water systems which are incredibly energy efficient -- this in itself is always a great selling point for the majority of homeowners these days. As energy prices soar and we are all made increasingly aware of the importance of turning to eco-friendly energy solutions, a geothermal solution is quickly becoming a more common choice for homeowners.

Most people are familiar with the concept behind solar energy, but many do not realize that around half of that energy is actually absorbed into the ground – and utilizing that energy can help to save up to 80 percent on the energy we use to heat and cool our homes and provide hot water for our showers and baths.

So how do geothermal energy systems work?

The usual model for a geothermal system involves sealed piping, which is placed beneath the ground through which water circulates with a little help from a heat pump system. This helps facilitate the exchange of heat between the earth and your property. During the colder winter months, the higher temperature of the ground is absorbed, concentrated and pumped into homes providing a warm,comfortable stream of air. During the summer the opposite can be employed. In this case, the heatpump absorbs the heat from your property before transferring it into the circulating water system,leaving your home feeling cool and comfortable.

Installing a geothermal energy system for your home can help to save a substantial amount of money on energy bills. The systems have considerably less work to do than more traditional heating and cooling systems – whereas furnaces utilizing fossil fuels are generally 80 percent to 90 percent efficient, many of these geothermal heat pumps have incredible efficiency of up to 450 percent. Not only does this help to reduce your heating and cooling bills, but it is also an incredible Eco-friendly method of heating and cooling your home.

We all have to do our bit these days to help preserve fossil fuels and reduce the carbon emissions which are slowly strangling our fragile planet. Geothermal energy systems are just one small step which can help you to do just that.

So is geothermal the right choice for cooling your home? Why not call in the experts and find out?

How Your Home’s Ductwork Design Affects Energy Efficiency

Monday 25 May 2015 17:11
Written by

crawford_11_22_12No matter how up to date or efficient your home comfort equipment may be, getting the full benefit depends on your ductwork design. Poor design wastes energy, is more costly, negatively impacts your comfort level, and even affects your indoor air quality.

Elements of ductwork design

Homes should have ducting systems that match the design of the home and its heating and cooling equipment. Some aspects of ductwork design are universal to any home. If ducts are compatible with the following, your system's in good shape:

    • Ducts shielded – Ducting should be running in conditioned spaces, spaces within heated and cooled areas. This could be interior walls, ceilings or between floors. If your ducting is mostly in the attic, basement or crawlspace, it must be well insulated. Otherwise, you're losing much of your heating and cooling before it reaches the rooms in your home.


    • Sealed joints – Joints connecting ducting to your equipment, each section or registers must be sealed to prevent air leaks. Air leaks can cause you to lose up to 30 percent of your heating and cooling.


    • Sloping bends – Duct sections that bend should have gradual slopes instead of sharp bends. A turn sharper than 45 degrees slows down airflow and reduces the circulation momentum.
 
    • Air returns – Air return vents should connect between rooms for the best circulation. Blocked return vents or rooms without air returns cause an imbalance in the circulation of heated and cooled air. The exchange of air in a room is also off balance without a free-flowing exit for air to be recirculated.


If your ductwork design is lacking in any of these areas, it should be checked by a professional technician. Upgraded ducting can greatly enhance your comfort and lower your energy bills. If you have questions regarding your home's ductwork or any other home comfort issues, please contact us at Crawford Services, Inc. We're always ready and happy to help our north Texas neighbors.

Heating Season In Dallas-Fort Worth Is Short, But Get Into The Habit Of Checking Your Furnace Filter

Monday 25 May 2015 17:08
Written by

Even though the heating season in Dallas-Fort Worth is only a few months long, there are still a few wintertime home maintenance jobs you'll want to do to keep up your home's energy efficiency. One of the simplest yet most important jobs is checking your HVAC air filters.

Dirty filters slow down airflow through the HVAC system, reducing thecrawford_12_25_12 system's efficiency and running up your energy bills. Severely clogged filters may blow out of the frame, allowing dust and debris to enter your system and home. Even worse, a dirty filter could cause your equipment to overheat and shut down.

Throughout the heating season in Dallas-Fort Worth, check your filters once a month. To inspect a mechanical filter, such as a fiberglass or pleated paper filter, remove the filter and hold it up to the light. If you can't see light coming through, you'll need to replace the filter.

Because higher efficiency filters can hold more debris, you may find you need to replace these filters less often, though on the other hand, their more elaborate filtering design may impede airflow through your system. An filter's Minimum Efficiency Reporting Value (MERV) indicates its efficiency.

MERV 1 to 4 -- Cheap 1-inch fiberglass filters trap only larger debris particles (those over 10 microns). Although they protect your HVAC system, they do little or nothing to improve your home's air quality.

MERV 5 to 8 -- In this range are the medium-efficiency pleated paper or felt air filters that can remove particles of 3.0 microns or larger.

MERV 9 to 12 -- These higher-efficiency pleated filters can remove particles as small as 1.0 micron in size.

MERV 13 to 16 -- With the highest efficiency of residential air filters, these filters remove particles as small as 0.3 microns. Because these high-efficiency filters may impede airflow, talk with an HVAC professional before installing one.

How The Forced-Air System In Your Dallas-Fort Worth Home Delivers The Goods

Monday 25 May 2015 17:05
crawford_1_3_13Ducted forced-air HVAC systems are the most widely used type of heating and cooling in the U.S. today. If your home has a furnace, standard heat pump or central air conditioner, then you have a ducted forced-air system. Knowing a little about how your system works will help you detect problems with your furnace or other equipment and make decisions about additional equipment such as air cleaners and humidifiers.Basic forced-air system components include:
  • A thermostat – This signals the system to turn on or off based on room temperature.
  • An air handler – An electric heating or cooling system includes an air handler that contains heat exchanger coils that heat or cool air, a blower to move conditioned air into the ductwork, a filter, and other components.
  • A furnace unit – A fuel-burning furnace that uses natural gas, liquid propane or heating oil contains a combustion chamber (burner) to burn fuel, a heat exchanger to extract heat, a blower to move warm air, and a flue or vent to release combustion gases from your home.
  • Ductwork – The typical forced-air system includes both air delivery ductwork to send heated or cooled air into your rooms and return ductwork to bring conditioned air back to the heater or air conditioner. Vents and registers also help supply and direct airflow.
When your system's thermostat senses the room temperature is below or above the set temperature, it signals the furnace or air handler to turn on. The blower fan draws room air through the return ductwork into the air handler or the furnace's heat exchanger.Next, depending on the type of system, either the furnace's burners or the air handler's electric elements turn on, or the heat pump starts up. When the air has warmed or cooled sufficiently, the blower fan pushes it into the delivery ductwork where it flows out to your rooms.Naturally, there's a bit more to a forced-air system than that, so if you need help understanding yours, contact us at Crawford Services.

Duct Cleaning: Will It Benefit The IAQ In Your Dallas Home?

Monday 25 May 2015 17:03
Written by

04_10_13Duct cleaning isn't a cure-all for poor indoor air quality, but in certain cases it can make a perceptible difference. Keeping an eye out for signs of dirty ductwork is especially important in the Dallas area, where our climate encourages dust buildup and mold growth.

You may benefit from duct cleaning if:

  • Your registers are releasing clumps of dust or debris, or blowing visible particles into the air.
  • You can see mold in or around your ducts.
  • You notice signs of rodent or insect infestation, such as mouse droppings or dead insects.
  • You've had construction done recently. Newly built and remodeled homes often have construction debris left over in the ductwork.


If you're dealing with any of these issues, after a professional duct cleaning, you can look forward to:

Fewer air contaminants – When debris blows out of your registers, it becomes airborne and there's a chance you'll breathe some of it in. These debris particles irritate your airways and can worsen allergy and asthma symptoms.

Better smelling air – Over time, duct buildup may produce unpleasant odors that permeate your home. This is especially true with mold and rodent infestations. Get rid of the buildup and you'll probably find your home smells better.

Greater efficiency – Air flows through clean ducts more easily than through ducts blocked with buildup. After duct cleaning, your system will heat and cool more effectively. Because your system won't have to work so hard to do its job, your energy costs will fall, too.

We follow the cleaning procedures outlined by the National Air Duct Cleaners Association (NADCA). As part of your cleaning, we'll:

  • Disassemble, clean and replace all supply registers and return air grilles.
  • Clean the ducts with a Rotobrush machine. This machine gently dislodges stuck-on debris, then immediately vacuums it up.
  • Mist the ducts with an anti-microbial treatment to hold off mold and bacterial growth.


Some dust in the ductwork is normal and doesn't necessarily mean a cleaning is in order. In many cases, duct cleaning would be an unnecessary expenditure.

To help you decide whether or not your ducts need cleaning, Crawford Services offers a free, no-obligation ductwork evaluation. A technician will use a duct camera to assess your ducts, then work with you to choose the best course of action. The technician will also offer suggestions for addressing the cause of any excess buildup.

If you suspect your ducts are dirty or you have other concerns about your indoor air quality, get in touch with us at Crawford Services. We provide value-driven HVAC solutions in Dallas and the surrounding area.

Understanding Air Filtration Basics for Your Dallas Area Home Begins With MERV

Monday 25 May 2015 16:59
Written by

07_04_13Air filtration is a vital component of indoor air quality. As the air circulates through your HVAC system, it passes through the filter, which captures and holds particulates and contaminants such as dust, mold, pollen, and even micro-organisms and bacteria.

When choosing an air filter to use in your heating or cooling system, you should pay particular attention to the filter's MERV level. MERV stands for Minimum Efficiency Reporting Value, and is an industry-wide rating of filter efficiency. MERV ratings indicate how effective a filter is at trapping airborne particles as small as 0.3 microns in size.

MERV ratings start at 1 and range as high as 16 for residential filters. Higher MERV numbers indicate better air filtration efficiency and the filter's ability to capture smaller particles.

  • MERV 1-4: Air filters in this MERV range are usually low cost, but they are only minimally effective. They are best at collecting particles of 10 microns or larger.
  • MERV 2-8: Medium-quality filters such as these are usually made of a pleated filter material that presents more surfaces where particles can be trapped. They are best against contaminants of 3 microns or larger.
  • MERV 9-12: These are high-quality filters that are very good for general use in air filtration. They can handle particles of 1 micron or larger.
  • MERV 13-16: These filters offer the highest efficiency air filtration for residential systems. They work well at removing smaller particulates of 0.3 to 1 micron. However, when the MERV numbers get this high, the filter may impede airflow, which will reduce system efficiency and performance. High MERV filters also may require system modifications in order to work properly. Consult with your HVAC technician on what air filter will work the best in your particular system.

Crawford Services, Inc. brings years of experience and customer care to the cooling and heating services it offers throughout the Dallas area. Contact us today for more information on the importance of air filtration and how to choose an air filter with the right MERV rating to meet your indoor air quality needs.

Air Filters Vary in Allergy Effectiveness: Which Type Is Best for Your Dallas Home?

Monday 25 May 2015 16:57
Written by

08_14_13Air filters in your central cooling and heating equipment serve as a barrier to common pollutants such as pollen, pet dander, dust mites and tobacco smoke, which find their way in your home every day. Without proper filtration, these allergens can ruin your indoor air quality, and set your respiratory system into a tailspin.

Aren't all air filters basically the same?

The answer is no. Fortunately, the HVAC industry has a standard rating system in place. All air filters come with a Minimum Efficiency Reporting Value, or MERV rating, that tells consumers how effective they will be at removing particles from the air. For residential purposes, ratings range from 1 to 16. For example, a standard 1-inch fiberglass filter with a rating of MERV 4 will remove less than 20 percent of particles down to 3.0 microns as they pass through your ductwork. This includes pollen, dust mites and carpet fibers. Upgrading to a pleated filter with a rating of MERV 8 will dramatically improve your indoor air quality by removing at least 70 percent of similar particles, in addition to mold spores.

What about HEPA filters?

High-efficiency particulate air (HEPA) filters use an advanced design to trap particles down to .3 microns with 99.9 percent effectiveness. They are primarily used in hospital or clinical settings. HEPA filters can be used in central HVAC systems in residential settings, but usually require professional modifications to existing equipment and ductwork, which can make them costly options for homeowners. Stand-aline HEPA air cleaners are also available for comprehensive air purification in the home.

HEPA-like air filters

Choosing an air filter with a MERV 7-13 can provide virtually the same level of filtration as a HEPA filter without the modifications required to install those types of filters. According to the federal EPA, filters rated above MERV 13 will not provide a significant increase in the reduction of indoor air pollutants but may impede airflow in your system, which is something to be avoided. Changing your air filters on a regular basis will do more to ensure that your indoor air remains clean.

At Crawford Services, we understand the importance of maintaining the air quality in your Dallas area home. Proper installation is the key to getting the most of any air filtration device, so call us today and let us put our experience to work for you.

Common Obstructions in Your Dallas Area Home’s Air Ducts

Monday 25 May 2015 16:54
Written by

09_19_13Air inside your air ducts isn’t necessarily going where it's supposed to. Neither is all the money you’re spending to cool or heat it. Residential forced-air ductwork is a major source of lost energy, low comfort levels and big utility bills. Most residential air ducts are delivering efficiencies barely above 50 percent. It’s no surprise: When energy was cheap, design and fabrication of home ductwork was frequently treated as an opportunity to skimp on building costs. Today, as these systems silently deteriorate, we’re paying the price for savings of the past.

A trained HVAC technician using calibrated equipment can pressure test the system, measure airflow and visually inspect the entire span of ductwork. Here are some of the common defects in air ducts he’ll be on the lookout for:

Clogged air filter. The most frequent cause of airflow-related problems, the air filter is often the first thing a technician will check when the system’s under-performing.

Dirty blower fan. Dust and dirt accumulation on blower fan blades reduce the fan's efficiency to move air. Since the output of the blower is matched to the size of the ducts, proper output is required to maintain air balance in rooms.

Collapsed flex ducts. Flexible air ducts designed to bend around corners may lose their material integrity over time and sag or even collapse entirely, cutting off all airflow.

Deteriorated insulation. Inside rigid ductwork, insulation lining the surfaces may deteriorate and collapse, interfering with free flow of air.

Supply duct leaks. Because supply ducts operate under positive pressure from the blower, leakage that spills conditioned air out of the ducts is most likely to occur on this side of the system.

Leaky return ducts. Leaks in return ducts can draw unfiltered air into the system from unconditioned zones such as the attic or under the house.

In North Texas, Crawford Services, Inc. is always raising the bar for quality service and customer satisfaction. Contact us for a skilled evaluation of your air ducts and a reliable estimate of what’s needed to restore optimum performance and efficiency.

Can Home Air Filters Help with Fall Allergies?

Monday 25 May 2015 16:50
Written by

Home air filters will help your Dallas home’s HVAC system to fight fall allergies.  But, not if they are improperly maintained.  Just like any other filter, a home air filter can fill up with the most undesirable dander and substances causing a blockage. To be safe, replacing your home air filter on a monthly basis will ensure that you are best covered against allergens.

filtersThe truth is, no matter how much you wash your hands, bathe, vacuum your carpets our just stay indoors, ragweed, mold spores and dust mites are going to get in. And, if you do not have adequate circulation in your house, then your home air filter cannot do its job.

Home air filters are only effective when the air moves through them. They can remove those nasty fall allergens that wreak havoc on your body, but not without proper circulation. The more circulation your home has, the better job your filters going to do for you. Make sure that air ducts and returns have been placed in sufficient places in your home, with no obstructions, to ensure that all air circulates in and out of them.

Your air ducts are another place that mold can spawn. They are also a haven for rodents and insects, so it is important to have your home air filter in place to filter everything out. In most cases you air ducts are not accessible or visible. So in these situations you may need to consider calling a professional out to inspect and possibly clean the ducts if necessary.

What most people fail to realize is that your in-home air can actually be much more polluted than the air outside. This is due to a number of factors which include tracking mold and ragweed in from outdoors, pet dander (skin flakes, saliva, urine, etc.), insect droppings and other pollen. When inside, these pollutants become trapped. They then bond with your household fabrics such as carpet, bed sheets, pillows and rugs. Once they have bonded with these fabrics, every time they get touched the allergens become airborne and you are their unwilling host. When they become airborne, they can also be sent through the air returns and filtered out by your home air filter.

Home air filter that have the highest MERV ratings are the most effective defense against allergens. MERV stands for Minimum Efficiency Recording Value. The scale is 1 – 20 and the higher the MERV, the better filtration you are going to get. Yet, before you grab the highest MERV rating available, it is important that you first check with your HVAC manufacturer’s recommendations.

The higher the MERV rating, the more particles it can collect, but that also means the HVAC system has to work harder to get the air through it.  This means that you have to weigh efficiency with allergen protection to choose the best home air filter for your individual instance.

For example, you might option for a standard flat panel filter, which has a low MERV rating, but a maximum efficiency.  These work fine, but they are only intended to protect the furnace and not cut down on your fall allergies. Home air filters like these provide up to four MERV’s of protection.  If you have severe fall allergies, you might want to look into something that can protect you from the ragweed a little better.

Pleated home air filters are considered a medium efficiency air filter. They generally protect you with a MERV rating of about 13. But remember, the more MERV’s, the harder your HVAC system has to work to get the air through. This is also the case with high efficiency filters and HEPA filters. Although they are both going to do a great job of protecting you from fall allergies, you will want to consider how efficient your system is going to be when it comes to paying the electric bill.

air-duct-cleaningIt is of imperative importance that you change your home air filter frequently, regardless of your MERV rating.  If your house has a lot of dust, maybe from construction, sanding or outside dust getting in, your filters are going to clog quickly. You do not want your HVAC system to become more costly than it has to be. If you are using a medium efficiency filter, it might be a good idea to change it monthly.

If you do find mold growth near your returns, make sure to get them cleaned out as soon as possible. If you are considering upgrading your HVAC system, you might option to get a unit that does not continually use indoor air. Using filtered outdoor air could be a good way to handle any circulation issues you may be having. Sending the old air out and the new filtered air in is a great way help eliminate indoor allergens.

But still, a system that uses outdoor air needs to have an adequate home air filter. It is the season for ragweed and as we all know, this causes hay fever. A medium efficiency filter will do, but then you fall back into making sure that it is continuously changed out. Most people who have suffered from allergies have seen a drastic difference in their symptoms when they simply changed out their home air filter monthly, instead of every three months.

And, the benefits will be seen way beyond your health.  Many homeowners who up the frequency of their home air filter changes also notice a difference in their electricity bill.  A clogged filter forces your HVAC unit to work excessively hard to get the air through. Just like with any forced air system, obstructions diminish the flow of air. Changing out your home air filter means better health and saving money. That’s just a win-win situation.

The simple truth is, there are a lot of ways that you can get sick or put your health at risk. The last way you want this to happen is through airborne fall allergens. A home air filter fights allergens for you constantly and can help keep you healthy and active for a very long time.

Air Filters and the Particles They Trap: Here’s What They Do for Your IAQ

Monday 25 May 2015 16:43
Written by

10_17_13Choosing air filters for your Dallas home is about more than just the price. While air filters with a higher Minimum Efficiency Reporting Value (MERV) rating are more expensive than basic types, the cost is often worth it to enjoy better indoor air quality (IAQ). However, choosing an excessively efficient air filter can be a bad decision as well due to blocked airflow.

Here’s a look at different types of air filters, what they trap and which applications they are designed for.

• MERV 1-4: Filters at the lowest end of the efficiency spectrum come standard in HVAC systems. They capture the largest particles down to 10 microns, which includes dust mites, carpet fibers and pet dander that could damage the equipment. They provide very little improvement for IAQ.

• MERV 5-8: Mid-range filters are appropriate for most residential applications. They trap particles down to 3 microns, such as mold spores, hair spray, pudding mix and dusting aids. They provide reasonable improvements to IAQ at an affordable price.

• MERV 9-12: These higher-efficiency filters are only necessary if you have severe allergies or other respiratory problems. They trap particles down to 1 micron, including milled flour, auto emissions, humidifier dust and Legionella bacteria.

• MERV 13-16: The highest-efficiency air filters on the MERV scale trap particles down to 0.3 microns, such as tobacco smoke, all types of bacteria and germs found in a sneeze. Because they have a tendency to block airflow considerably, filters with this high rating are not appropriate for residential applications. They are reserved for use in hospitals, smoking lounges and commercial buildings with superior IAQ.

• MERV 17-20: These are considered High Efficiency Particular Air (HEPA) filters, capable of trapping more than 99 percent of particles less than 0.3 microns, including viruses, carbon dust and combustion smoke. These are certainly not designed for HVAC systems, but they can be found in vacuum cleaners and portable air cleaners.

To summarize, the best air filters for home use are between MERV 5 and 12, depending on your IAQ needs. To learn more, please contact Crawford Services today.

Avoid Costly Air Conditioning Repair With Springtime AC Maintenance

Monday 25 May 2015 16:33
Written by

Avoiding air conditioning repair needs to be a top priority this year. After the unusually warm winter this year, weather experts are predicting a very warm summer. And home owners’ AC system will be called upon over the next few weeks as spring warms up and the days get warmer. But is their air conditioning service up to the task? If you haven’t scheduled your annual maintenance checkup, there’s no time like the present.

logo-s2How can springtime maintenance help avoid air conditioning repair?

Beat the Summer Air Conditioning Repair Rush

Perhaps not surprisingly, many homeowners don’t think to have their air conditioning service worked on until they need serious air conditioning repair. Unfortunately, this usually happens at the peak of the cooling season, when the systems are running the hardest. It also means they will have to wait for hours, if not days, for an air conditioning repair technician.In the middle of June. Good luck with that.

Catch Problems Early Before Air Conditioning Repair Becomes Costly

If there is something wrong with a home HVAC system, it would be better to catch it now, rather than risking a costly and poorly-timed emergency repair call during the hottest part of the year.

In addition to saving the family from the sweltering inconvenience of a broken AC system, catching small problems early allows HVAC technician to make the necessary fixes, which prevents costly air conditioning repair down the road.

An air conditioning repair call will often cost much more than the small repairs, because left unchecked, small damage to small, easily accessible components turns into extensive damage to harder-to-reach components. The phrase “penny wise, pound foolish” is appropriate, since it is smarter to pay for the maintenance call and small repairs, which saves on the costs of repairs and replacements of expensive components.

Some of the items that are covered in this thorough inspection:
  • Electronics will be tested for operational safety.
  • Coils will be cleaned.
  • Ducts will be inspected for efficiency, and leaks will be properly sealed.
  • Refrigerant charge will be assessed for accuracy, and your technician will search out and repair any leaks in the system.
  • Filters will be changed to provide for cleaner air in the home.
  • Maximum efficiency over the long term


b7aac3fb-5117-4ffc-bd65-7243e2e077a1In addition to saving the expenses of emergency air conditioning repair calls and early replacements, springtime maintenance will also enhance the air conditioning service efficiency, which will increase comfort, and reduce energy costs.a

Furthermore, by scheduling annual maintenance, it will alleviate the burden that cooling season puts on a home’s air conditioning components, and reduce the wear and tear they experience. In effect, it is possible to extend the life of the air conditioning service, ensuring energy savings for years to come.

Has The Air Conditioning Service Filter Been Changed?

Monday 25 May 2015 16:27
Written by

Your air conditioning service needs its filter changed every few months in order to work at peak efficiency to keep your home comfortable. There are many things that play into having an efficient air conditioning service, but a key factor is your system’s air filter. Keeping a clean and efficient filter in your air conditioning service positively affects the system and your home in many ways.

Filter Properties

Filters come in various sizes and types. Some are made to be disposable, while others can be cleaned and reused. The air cleaning properties of a filter are defined by the MERV, or Minimum Efficiency Reporting Value, which ranges from 1 to 16 for residential use, and evaluates a filter’s efficiency based on how small of particles it will filter out. The higher the number, the smaller (and more) particles will be stopped.

Effects of Bad Filters

If you have an old, dirty filter in your air conditioning service, it will interfere with airflow, greatly reducing its efficiency. This, in turn, forces the air conditioning service to work harder to get the home cool, which costs you money. A clogged filter will also allow dust and debris to build in your air conditioning service, which can damage important parts, often requiring repairs as well as expensive duct cleaning.

When to Replace

It helps to have a regular schedule for changing your cooling system filter. If you have a maintenance agreement with a local professional who comes by regularly, he can change out the filter at that time. However, since it’s advisable to change the filter every two or three months, you should replace it yourself during periods of high use, such as in the middle of the summer.

A clogged filter in your cooling system is an easily fixed problem, and doing so can result in big savings and greater comfort inside your home.

AC Repair is a Time to Replace R22 Freon In Your System

Monday 25 May 2015 16:22
Written by

AC repair may be the best time to bring your HVAC equipment into compliance with the U.S. Clean Air Act. That's the act that requires all production of R22 Freon to cease, in compliance with the 1987 Montreal Protocol.

If your air conditioner is among the 80 percent in the country that use R22 refrigerant (those manufactured before 2010), you have another factor to consider when making AC repair, service, and/or replacement decisions.

Overall, the HVAC industry has done a good job of transitioning to alternative refrigerants such as R410A, while phasing out R22 Freon. R410A, also known as Puron, Forane 410A and other brand names, does not harm the ozone layer. New high-efficiency air conditioning systems and heat pumps use this refrigerant.

So if you're upgrading and building on your home, or even considering upgrading your HVAC system, make sure your new system uses R410A. You’ll save energy, and R410A prices are consistently low and stable.

AC repair or replacement?

Sooner or later, all systems fail and need to be repaired or replaced. With air conditioners and heat pumps, repairs often involve the compressor, expansion valve or a leak in the heat exchanger. Any one of these repairs may require replenishing R22, and by a substantial amount, which adds to the cost of the AC repair. Generally, if a major AC repair occurs, and it costs roughly half of what a replacement system would cost, it’s wise to opt for the replacement upgrade if it’s within budget.

Well-maintained AC systems are expected to last about 15 years, which means if it was made in 2009, you've got about 12 years left. If it was made in 1997, you're looking at some AC repair and replacement issues soon. If your system is getting up in years, it’s wise to start thinking about options.

No one knows the cost of replacing the R22 once 2020 rolls around, but you may be better off looking for a replacement during your next AC repair call, rather than when the demand for AC repair techs is heavy, and it's harder to find them.

Lower Your Air Conditioning Service Load For Leaner Energy Bills

Monday 25 May 2015 16:20
Written by

Your air conditioning service load can be lowered by taking a few steps that can help you reduce the "cooling load" in your home. Your “cooling load” is the amount of energy your air conditioning service uses to cool your home. The most efficient way to reduce this load and trim your energy bills is to prevent your home from heating up during the day.

Shield Your WindowsTo block the heat but let in the light, apply a sun-control film to your windows or install fabric sunscreen blinds. Outdoor awnings and rolling blinds also keep the heat out. Indoors, choose window treatments with white or metallic-backed surfaces that reflect the sun’s rays.

Create Less HeatWhen possible, keep your lights off during the day. Switch to CFL or LED bulbs, which generate less heat than traditional incandescent bulbs do. Wrap your water heater in an insulating jacket to limit the heat it emits. All this heat builds up, which keeps your air conditioning service running.

Seal Air LeaksIn summer, air leaks in your home let in hot outdoor air. You can significantly boost your air conditioning service and lower your cooling load by stopping major leaks. Check your door and window frames for cracks and seal any with weatherstripping. Also look for leaks around electrical outlets, plumbing lines and exhaust fans.

Improve Your Attic InsulationInsulation in the attic slows the transfer of outdoor heat into your home. Experts from the federal Energy Star program recommend 10 to 14 inches of insulation, depending on the type. Most insulation doesn’t block airflow, though. Before you add insulation, find and repair any air leaks.

Seal your HVAC ductsLeaky ductwork allows conditioned air to escape before it reaches your home’s living areas. When you seal those leaks, your air conditioning service will cool more efficiently, using between 10 to 50 percent less energy. If you’re not sure how to find and seal leaks, an air conditioning service expert can help.

New Air Conditioning Service Carry Lifetime Costs

Monday 25 May 2015 16:06
Written by

A new air conditioning service will definitely make your home more comfortable, but be sure to consider the lifetime costs when making your buying decisions. If you’re shopping for a new air conditioning service, you’ll want to consider not only the immediate costs of the system, but its lifetime costs as well. Spending a little more up front can save thousands in repairs and energy costs over the life of owning it. It can also mean the difference between enjoying a cool comfortable home and suffering during summer’s heat.

When replacing an older air conditioning service with a newer, energy-efficient cooling system, you’ll quickly see an improvement in your electric bills. A new central air conditioning service can save you up to 30 percent off your summer energy bill. Be sure to find central air conditioners with Energy Star labels that have SEER ratings of 14 or higher and EER ratings of 11 or higher.


What do those ratings mean? The Seasonal Energy Efficiency Ratios (SEER) measures the efficiency of your unit over the entire cooling season, while the Energy Efficiency Ratio (EER) measures the efficiency of your unit while it’s operating during the hottest days.Shopping for a new air conditioning service can be challenging. Why not contact Crawford Services? We’re proud to serve North Texas, including the Dallas-Fort Worth area. Our trained technicians can guide you to the best air conditioning service solution for your home, budget and comfort. They'll measure your home, check out your old equipment, and see what kinds of upgrades you can make to your new service.

New Air Conditioning Service? Use The EnergyGuide Label When Shopping For a New System

Monday 25 May 2015 16:02
Written by

Buying an air conditioning service or furnace gets a lot easier when you’re guided by the bright yellow EnergyGuide Label. It’s much more conspicuous than a price tag and actually gives you a lot more information. An air conditioning service has two costs: The purchase price you pay up front and the cost down the road for the energy to operate it and any maintenance or repair costs. Long after you’ve paid off that first price tag, you’ll still be paying for the other costs.

Understanding the information on the EnergyGuide label can make the difference between an informed buying decision now and buyer’s remorse later. Here’s what you need to know:

The upper left corner of the label spells out the general features and performance data relating to that particular air conditioning service and other similarly priced units. On the right is the name of the manufacturer and the model name and number describing this particular air conditioning service. A simple Internet search of the model number will provide you with all the technical details about the product and reference materials.

The middle section of the label displays information about the energy efficiency of the air conditioning service relative to other equivalent models in its price range. If the label describes a central air conditioning service, a scale depicts the SEER (seasonal energy efficiency ratio) range from the least to the most efficient models. An arrow placed on the scale indicates the ranking of this unit in the SEER range, and a bold numeral above the arrow shows the exact SEER rating. On a furnace, an AFUE (annual fuel utilization efficiency) scale appears, and the placement of the arrow marks the unit’s relative efficiency ranking.

At the lower right of the EnergyGuide label, an Energy Star icon may appear. This indicates that the appliance or product uses less energy than standard efficiency units and results in less environmental impact. For air conditioning service, this normally denotes a high-efficiency unit with a SEER rating of 14 or above. Gas-fired furnaces with AFUE ratings of 90 percent here in Texas qualify for the Energy Star label.

Your AC Repair Tech Can Find and Fix Air Leaks

Monday 25 May 2015 15:54
Written by

Your AC repair technician can help you identify issues that can greatly affect your home's energy efficiency, like old HVAC systems, and even locating air leaks. Finding and fixing air leaks will provide many benefits, including keeping your heating and cooling and AC repair costs lower, and your house more comfortable.

Drafts are a tell-tale sign that a home has air leaks. They make it difficult for rooms to stay at the desired temperature, and you have to constantly adjust the thermostat to make up for the drafts.

Drafts can lower indoor air quality, which leads to an increase of asthma and allergy symptoms, and decreases your family's overall health. Air leaks also cause the HVAC system to work harder, which increases costs and reduces its life. Once that happens, you can expect a hefty repair bill, or even a much more expensive AC replacement. You'll also face the same problems in the future if you don't get the original problem fixed.

Locating places where air is leaking from a home is relatively simple since most air loss occurs in the same types of locations in homes. If air is leaking from window and door frames, try weatherstripping to seal the leaks. While this is not an issue the AC repair tech can help with, a new set of windows and doors can make a dramatic difference in a home's energy costs.

Damaged ductwork is another common area for air leaks, and these holes and cracks can be sealed with duct sealant or foil tape, and this IS an AC repair tech issue. Ask your HVAC contractor to do an energy audit and fix any of the ductwork issues he can find.

Professional help may be required to ensure your home is operating at its maximum efficiency. A qualified AC repair technician can perform an energy evaluation to find exactly where a home is losing air. He or she can also provide proper preventive maintenance and AC repair to the cooling and heating equipment to extend its life.

Zoned Heating And Air Conditioning For Maximum Efficiency And Comfort In Your Dallas Texas Home

Monday 25 May 2015 15:53
Written by

02_12_13An ordinary non-zoned HVAC system poses two problems: it rarely maintains comfortable temperatures in every room, and it wastes energy by sending conditioned air where it isn't needed. For greater comfort and efficiency, you need better control. Installing zoned heating and air conditioning in your Dallas, Texas home gives you just that.

A zoned system allows you to control the temperature in different parts of your home. The system depends on two features: motorized dampers (adjustable metal plates) in the ducts and a multizone programmable thermostat. The thermostat can be set to heat or cool separate zones independently at different times of the day. The dampers open and close to control airflow to each zone.

A well designed zoned heating and air conditioning system provides benefits such as:

Comfort in every room – Zoning allows you to heat or cool each part of your Dallas, Texas home based on your preferences. You can limit airflow to rarely used rooms while maintaining more comfortable temperatures in rooms you use often.

Zoning is especially important in multi-level homes. A single thermostat only maintains the temperature where it's located, usually on the main first-floor level. Because warm air rises, however, the upstairs may be up to 10 degrees warmer than downstairs. Zoning uses multiple thermostats to maintain your preferred temperature on each level.

Better energy efficiency – A properly designed zoned heating and air conditioning system could lower your energy use by up to 20 percent, according to experts from the U.S. Department of Energy. You could save even more by programming multiple setbacks into your thermostat. These automatically reduce the heating or cooling when you're asleep or away.

Greater convenience – With a zoned system, you can easily program different temperatures for your bedrooms at night and your living room during the day. What's more, multiple thermostats let you adjust the temperature right where you are instead having to go to another part of the house.

A zoned heating and air conditioning system's efficiency depends on proper design and installation. If you're considering zoning for your home, contact us at Crawford Services. We have several decades of combined experience designing and installing efficient HVAC systems for Dallas-Fort Worth area homeowners.

Our goal is to help educate our customers in North Texas about energy and home comfort issues (specific to HVAC systems).

A/C Contractors Will Tell You – Regular Air Filter Changes Are a Must

Monday 25 May 2015 15:50
Written by

02_21_13The best A/C contractors will tell you: The efficiency, effectiveness and all-around condition of your home heating and cooling systems depend on many factors. These include regular maintenance and prompt repairs of problems when things go wrong. Doing these two things can protect your comfort system investment and extend the life of your equipment for 5-10 years longer than systems that are not properly maintained.

A significant component of HVAC system maintenance that is often neglected, or simply forgotten, is regular air filter changes. Professional A/C contractors are unanimous in their advice: Regular air filter changes are necessary to keep your indoor air clean and your air conditioner or furnace working at peak performance.

You should check the air filter in your HVAC system at least once a month. Dirty filters should be changed whenever you find them. Filters should be changed every three months as a matter of routine maintenance. Occasionally filters of the highest grade can be changed annually due to the UV lights and processes built into these advanced filtration systems.

Some of the benefits you will see from regular air filter changes include:
  • Improved indoor air quality: Dirty filters contain large amounts of the particulates and contaminants you're trying to remove from you air. If the filter gets too full, it won't be able to capture more material. Worse, it can release contaminants back into your home's air. A clean filter means clean indoor air.
  • Decreased malfunctions and breakdowns: Dirty filters are a major source of HVAC system problems. A dirty, clogged filter blocks the airflow that your furnace or air conditioner needs to operate. Fans and air handlers work overtime to push air through the filters, resulting in needless wear and quicker breakdowns.
  • Improved system performance and efficiency: Dirty filters cause your HVAC system to work harder than necessary, which drives up energy consumption and increases your monthly heating and cooling bills. Dirty filters can also impair system performance, causing your furnace or air conditioner to take longer to heat or cool your home. A system working with a clean filter is also much less likely to have an expensive breakdown or component failure.


If you need heating, air conditioning or plumbing work in your Dallas or North Texas home, call Crawford Services, Inc. for professional services by expert A/C contractors who will get your HVAC systems working again. Contact us today for more information on the importance of changing air filters in your heating and cooling systems.

Air Conditioning in Your Dallas Home: Control It With a Programmable Thermostat

Monday 25 May 2015 15:46
Written by

07_24_13When it comes to air conditioning, there's an easy way to save money on your energy bills this summer: install a programmable thermostat. Using a programmable thermostat will help you resist the urge to constantly adjust the air conditioning, and help reduce those high summer energy bills.

Setting your thermostat: Normal programming

When deciding how to program your thermostat, first look at your family's schedule. Note the times of day when the house is empty. Set back the temperature while you're away from the house or sleeping, then program it to return to a daytime comfort setting before you awake or return home. For example, if you arrive home from work at 5 p.m., it can be programmed to start cooling down your home around 4:30 p.m. so that it feels comfortable by the time you walk through the door.

Your settings will depend on personal preference, but every degree you set back your thermostat over an eight-hour time span can save you 1 percent on your energy bill. It will take some adjusting, but the goal is to avoid constantly adjusting your air conditioning, which wastes energy.

Setting your thermostat: Using the override function

Nobody's schedule stays the same every day, so sometimes you will need to manually adjust your pre-programmed settings. Most programmable thermostats are equipped with an override function that lets you temporarily change the temperature. If you find yourself constantly using this feature, you may need to take a look at your settings and do some fine-tuning. Your thermostat should automatically return to your programmed settings after a set period.

Setting your thermostat: Vacation mode

For longer trips away from home, many thermostats also have a vacation mode. This is handy if you will need to override your existing programming for a period of several days.

If the thought of installing or setting up your programable thermostat is overwhelming, let our qualified technicians at Crawford Services walk you through it step by step. Helping you make the most of the air conditioning in your Dallas area home is our top priority.

Your Dallas A/C May Need Replacement When R-22 Is Phased Out

Monday 25 May 2015 15:42
Written by

08_22_13Your Dallas A/C is most likely among the more than 80 percent of air conditioners in the United States that use R-22 refrigerant. Unfortunately, changes are underway in the HVAC industry that may eventually require a complete replacement of your home comfort system.

Refrigerant is the substance that allows your air conditioner or heat pump to generate cooling for your home. R-22, also known as HCFC-22 or the brand name "Freon," has long been the industry standard refrigerant, and until recently it has been plentiful, inexpensive and easy to get. New government regulations are reducing new supplies of R-22 refrigerant more and more every year. In response, prices have risen dramatically, and R-22 is becoming more difficult to find at an affordable price.

Along with other nations, the U.S. government has determined that R-22 refrigerant is harmful to the environment because it increases depletion of the ozone layer. The Clean Air Act requires that R-22 refrigerant be gradually phased out for use in air conditioning systems, and since 2010 no new A/Cs or heat pumps have been sold that use R-22. By the year 2020, R-22 will no longer be manufactured. The only way to acquire R-22 will be through recycling or reclaiming it from existing air conditioning systems.

Instead of the standard R-22 refrigerant, air conditioning systems must use more environmentally friendly refrigerants such as R-410A or R-422. While these newer refrigerants are safer for the environment, Dallas A/C system owners will be faced with a shock when they try to convert: R-410A and R-422 refrigerant will not work in air conditioners that use R-22 without substantial modifications to the equipment.

The status of R-22 refrigerant leaves millions of American homeowners with two expensive choices.

  • Continue using R-22: Dallas A/C and heat pump owners can continue to use R-22 in older systems. However, as supplies dwindle, the cost of R-22 is almost guaranteed to become extremely expensive, even prohibitively so. For example, in early 2013, the EPA restricted the production of R-22 by about 30 percent over previous levels.
  • Completely replace existing air conditioning systems: While this will be inconvenient and costly for most homeowners, it provides the opportunity to replace your Dallas A/C with a newer high-efficiency air conditioning system that is more reliable, more effective, and more economical to operate. The monthly savings from a system replaced now will recover much of the cost of the new system by 2020. Plus, new high-efficiency central A/Cs and heat pumps may qualify for a $300 federal tax credit.


Dallas area customers can count on Crawford Services, Inc. for fast, reliable air conditioning service and maintenance. Contact us today for more information on the phase-out of R-22 refrigerant and what it will mean to your Dallas A/C system now and in the future.

A/C Repair Sometimes Includes Clogged Condensate Drains: Learn How to Prevent Them

Monday 25 May 2015 15:38
Written by

 09_03_13One common preventable A/C repair is a clogged condensate drain that may cause several problems for you and your home. This issue can can raise the humidity in your home plus bring headaches such as water damage, mold, bacteria and even mosquitoes. Clearly, this is something that homeowners should keep an eye on and be vigilant if a problem arises.


There are a few reasons why this problem may occur. Dust and debris may enter your condensate line near your air handler over time and eventually plug up the line, blocking the flow of water that needs to drain as your A/C creates condensation on the evaporator coil. In addition, if your condensate line was improperly installed (not at a steep enough angle), debris may also build up and create a blockage throughout the line. The main thing is to keep your condensate drain line free of debris and mold. If you can stay on top of this issue with regular maintenance, a full A/C repair need not occur.

There are a few options when it comes to cleaning your condensate drain that should work. Simply removing debris manually or with a small plumbing snake may be all you need to do. However, remember that since the pipe is likely plastic, you should attempt to do this gently to avoid unnecessary leaking or breakage. Some models even have cleanout ports that are easily cleaned with soap and water. If your drain has a heavy clog that has been building up for some time, you may need to resort to blowing out the clog either with compressed air or a vacuum pump. If this is necessary, you may want to contact an HVAC professional.

If you would like more advice about your condensate drain and its maintenance in order to prevent an A/C repair, feel free to contact us at Crawford Services, Inc. We provide superior HVAC services to the Greater Dallas area.

Don’t Let the Air Conditioning Repair Bill Hurt You

Monday 25 May 2015 15:31
Written by

The air conditioning repair bill can really bite you. If you live here in the Dallas area and you want to stay comfortable during these hot summer months, you really need to make sure that you are maintaining your AC unit. What that means is checking the condensate drain every three months, switching out or at least checking your air filter every month, cleaning out the interior of the unit and keeping the weeds and other growth away from it.

There may always be a time when you need air conditioning repair repair done, but you can minimize those instances just by doing the little things that prevent a bigger mess. Take for instance your condensate drip hose. The last thing you may think of may be the first thing that causes you to call for air conditioning repair service. These drips do not just get rid of the water in the air, but the dust, grime and allergens also. Mix all those together and you have an ugly mess that will build up in your drip line or in your drip pan. That buildup can cause the drain to malfunction and the next thing you will have is a mess on your floor as well as in the unit.thermostat

The same principle can be applied to the air filter. If it collects to much dust - to the point where air cannot travel through it anymore - you will burn the unit out and your air conditioning repair bill might turn into an air conditioning replacement bill. In other words, it is very important to stay on top of this.

The outside unit is built to stand up to the elements, but there are things that can get into the unit that will make it inefficient and give you cause for air conditioning repair. The main thing to look for is debris. Anything small can get inside the unit where the fan blows and cause a strain. But, the most important place to keep everything clean is the coils that surround the unit. Put simply, the fan blows the air upward, but it sucks the air from below through the coils. These coils are very thin metal and can easily be bent or moved. Kids love to do this to the thin metal strands of coil. If you have any bent or damaged like this, you need to take a thin knife and straighten them.

It is always the little things that will have you on the phone for air conditioning repair. The weeds and outside growth are the last thing you want to cause this. Keep them trimmed and away from the unit. It might also be a good idea to simply spray weed killer on all the vegetation around the unit. If you have bushes that you do not want to get rid of, just make sure to keep them trimmed.

Proper maintenance means fewer issues down the road – keeping money in your pocket and your home cool this summer.

AC condensation is a unique component to your central air unit that makes for a more comfortable lifestyle, especially in your Texas home. Just consider what makes the summers so miserable here in Texas: humidity! Sure it is hot, but if you did not have the humidity to go with it, it might be a little more tolerable. The same goes for inside your home. If your home has a lot of moisture in it, then the temperature can only help so much.

03_21_13That is why central air units are equipped with an evaporator. These cooled units receive the warm air in your house through the return air ducts. Once they reach the evaporator, the air is cooled and water is removed from the air. The cooled air is then sent back through the house and repurposed for comfort. The AC condensation is then discarded through a line or a drip pan and returned to the outdoors.

There are a few important things to remember: It is okay if your condensate line drips all the time. That just means moisture is being pulled from the air and discarded. The AC condensation also includes the dust and debris from inside the house, so it has the potential for buildup. In cases like these, it is a good idea to check your condensate line often. Lastly, even though the evaporator coil removes the dust and water from the returned air, it is important to change your air filter quite often because the dust and allergens can still get through.

You might also utilize the AC condensation that comes from your house to water plants and gardens. It is always a good idea to put that excess water back into the ground, so why not keep your garden healthy with it? It is okay if the dust is mixed in with it, vegetation grows outdoors with it there already.

Keep your home running smoothly this summer by understanding your system and keeping it properly maintained.

truckAir conditioning repair bills in your Dallas home can be avoided by ensuring that all of your maintenance on the unit is up-to-date. These maintenance issues are the little things that always slip a homeowner’s mind, but they make up more 90 percent of all air conditioning repair costs.

Air conditioning repair can be due to a clogged condensate drip line. Failure to regularly change the air filters inside your home can also lead to AC failure. How about your electrical unit? A breaker trip is not the only issue, failures sometimes come from the exterior control unit, meaning a fuse could have blown. Refrigerant can also be an issue. An adequate level must be maintained to ensure the unit functions properly.08_08_13

Many homeowners do not have the skills necessary to complete the required steps to keep their AC (both indoor and outdoor portions) in good working order. It is best for your unit to be professionally maintained, with routine maintenance and cleanings. These cleanings will remove any debris that has gotten into the unit and straighten the coils that bring the filtered air into the fan. Comprehensive services, like those offered by Crawford Services, will also include changing your filters and cleaning out the condensate line.

Your condensate line does not just drip water that your HVAC system has removed from the air, there is also dust and debris from your house that gets mixed in and eventually clogs up the lines and drip pans. These AC parts need to stay clean in order for proper drainage. Otherwise, you will just have to shell out more money for air conditioning repair and possibly even home repairs if there is an overflow.

Crawford Services changes the air filters, tests the capacitor, tests the refrigerant and tests the actual cool air that is being produced. These combined features will make sure that your air conditioning repair is either non-existent or minimal at worst.

Contact us today for more information and let us help keep your unit it top performing shape.

Avoid Air Conditioner Repair this Spring by Preparing in the Fall

Monday 25 May 2015 15:09
An air conditioning repair bill at the start of spring is one of the most undesirable situations for a homeowner to have. The truth is, most people do not even turn their air conditioning on until it gets so hot that they are miserable. So, when the nasty heat rolls into Dallas next spring and you want a little relief, the LAST thing you want is to have to do is call someone in for air conditioning repair.

The fall is here and Dallas folk are winding down their AC unit usage. Crawford Services has a couple of fall tips to make sure your unit is shut down properly though the winter months, allowing you to avoid air conditioning repair in the spring.

2_5_13Although AC units were made for the outdoors and don't require covering, manufacturers may not have taken a few things into consideration. Falling debris, maybe from barren winter trees or icicles can fall and land on your unit, possibly damaging it.

But, there are a couple of things you need to know before you cover your unit - to help avoid future air conditioning repair. For example, the unit should never be completely covered with a tarp. It may be tempting to protect your outdoor unit from the wind, snow and debris, but those things are actually not an issue for the unit. If you cover the unit up completely, however, you may have a mold issue from a lack of ventilation - you may also have a critter nesting issue. Critters like to chew through wiring, so their trail of destruction could definitely lead to air conditioning repair in the spring. You only need a solid hard board to put over the top of the unit to absorb the impact of any debris.

If your summer AC activities are over, go ahead and flip the disconnect switch by your AC unit. The last thing you want to do is accidentally turn the AC unit on after it has been winterized. This is a surefire way to guarantee air conditioning repair in the spring. Crawford Services stands ready to help you with all of you needs.

Dallas Heating Bills Can Be Reduced With Proper Programmable Thermostat Settings

Monday 25 May 2015 13:36
Written by

allas heating may not be the most expensive in the country, but our chilly North Texas winters can still run up the bills. One easy, inexpensive way to keep those bills down is with a programmable thermostat.

Programmable thermostats let you define a pre-set schedule for your heating and air conditioning. They provide a convenient way to manage your heating and cooling for energy savings.

Turn your heat down by seven to 10 degrees for at least eight hours a day and you can reduce your yearly heating bill by 5 to 15 percent. You'll see a savings of up to 1 percent for each degree you lower the thermostat for eight hours a day. A Dallas heating expert can help you choose temperatures for optimal comfort and savings.

For the greatest savings, there are a few guidelines you'll want to follow.

Choose long energy-saving periods – You'll see the greatest savings if you choose energy-saving set-points that are at least eight hours apart. For example, you might choose a lower temperature for the eight-hour period when you're in bed or away at work. Contrary to what many assume, letting the house get cold doesn't force your furnace to work harder than normal to raise the temperature again.

Avoid frequent overrides – The override modes on your thermostat let you temporarily change your thermostat setting without changing the pre-set programming. While there are appropriate times to use the override feature, you'll run up higher heating bills if you frequently override your energy-saving settings.

Use the right override – "Temporary" and "hold/permanent" are the two override modes found on most programmable thermostats. "Temporary" mode changes the temperature only until the next pre-programmed period. This mode should be used for short-term adjustments, such as unexpectedly cold days. "Hold/permanent" maintains your chosen temperature until you cancel the override. This mode is appropriate for times when you're away for two or more days, such as a vacation.

Pick moderate temperatures – Setting your thermostat to 80 degrees doesn't heat your home quickly. It only wastes energy. For comfortable Dallas heating and energy savings, you might choose 68 degrees for times you're home and awake, then program your thermostat for seven to 10 degrees lower for the times you're in bed or away. For more precise control over your home's temperature at specific times, choose a thermostat with adaptive recovery technology. These models calculate the amount of time needed to reach the pre-set temperature, then run the furnace so your home reaches that temperature by the programmed time.

If you're interested in installing a programmable thermostat or any other energy-efficient HVAC equipment, contact us at Crawford Services. In the Dallas area, we provide reliable, cost-effective HVAC care.

Our goal is to help educate our customers in North Texas about energy and home comfort issues (specific to HVAC systems).

Air Conditioning:The History of Refrigeration

Saturday 23 May 2015 15:48
Written by

Air conditioning technology has come a long way since the latter part of the 1950s when there were just two types of compressors available in the United States for refrigeration and air conditioning units – a choice of dynamic centrifugal refrigeration machines or positive displacement machines. The potential of the ranges overlapped, but many experts recognized that there would be plenty of room for improvement. 03_05_13

Air conditioning development soon became focused on bridging higher speed compressors, which aimed to combine the advantages of both types of design – the centrifugal and the reciprocating models. This quickly led to a reduction in surging which was recognized to be useful in many different applications of refrigerants under high pressure.

The trend was definitely going the way of portable air conditioning units which were engine-driven,replacing the traditional reciprocating function with oil cooled rotary machines, initially utilizing the sliding vane design before being replaced by the screw design. The capacity control was effectively achieved by a variation of the RPM without unloading the compressor device.

This screw compressor design had been patented in 1934 in Sweden and landed in the USA in the 1950s at a laboratory belonging to the Worthington Pump Corporation. After numerous tests and evaluation procedures for its potential in refrigeration and air conditioning applications, the design got a resoundingly negative response. The major problem was the intense amount of noise which was produced from the high speed, oil-free, compression based machine. The device also needed mechanical speed increases even if it was directly attached to two electric motors measuring around 3,600 RPMs. This machine was noisy, inefficient and would prove to be difficult for air conditioning manufacturing purposes -- but it was a start.

The Swedish company which owned the rights to the 1934 design (Svenska Rotor Maskiner AB) began development of an oil flooded device with a much simpler manufacturing procedure – there were no timing gears, and this machine could be coupled directly to the two-pole motors simultaneously. Other improvements were also made to the design, including fixed RPM drives. With these improvements the technology suddenly looked a whole lot more viable in the world of air conditioning and large scale refrigeration.

By the 1960s, three companies had successfully pioneered the latest technology and developed machines specifically designed for refrigeration units - plus some large scale industrial type air conditioning units. All three manufacturers initially used the standard rotors design, with rotors of similar lengths and diameters and ratios ranging from around 1.0 up to 1.7. Changes were needed,however, to really make an impact on the air conditioning market for which it was necessary to develop hermetic screw type compressors.

The US manufacturing company D/B – Dunham-Bush seized the new technology and ran with it having the foresight and the sheer guts to enter the air conditioning marketplace using hermetic screw-type compressors, meeting the traditional centrifugal system developers head-on in the fight for supremacy. 1967 saw the official launch of the DBX line of machines utilizing the screw compressor functions, and a large display of hermetic screw compressors and chillers were unveiled at the winter trade show.

Fast forward to the 1980s, and although a handful of manufacturers had embraced the screw compressor function in the 1960s, 1988 saw more than 20 different manufacturing organizations, including five in the United States, realizing the commercial viability of the venture.

There are a number of advantages for utilizing screw compressor technology in air conditioning and refrigeration units. For a start they are generally smaller in size, lighter in weight and a much more affordable option than those utilizing hermetic motors or basic compressors. They can also operate both reliably and efficiently while coupled directly to 2-pole sixty or fifty cycle electrical motors with increased RPM’s, VFD’s (variable frequency drives) and step up gears. This leads to the flattening of the volumetric efficiency curves against the compression ratio, which leads to a reduction in the compressor displacement. This is required as compared to any reciprocating model with a higher CR used typically in low or medium temperature air conditioning, heat pump and refrigeration applications.

The technological advancements have really moved forward at an incredible rate during the last 50 years within the world of air conditioning and refrigeration. We’ve all come to rely on this technology so much in our everyday lives; it’s difficult to imagine how we would ever manage without it.
