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.

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.


If you've had hot spots in past summers and cold spots in the winter, they can even help you pinpoint those as well, and see what sorts of changes and fixes need to be done to keep your energy costs down and your home as comfortable as possible.

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.

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.

Why Do I Have AC Condensation?

Monday 25 May 2015 15:25
Written by

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.

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.

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.
