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.

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.

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.
For more pro tips on using a humidifier or other HVAC equipment, please contact us at Crawford Services. In the Dallas area, we can help you find safe, affordable, effective ways to stay comfortable.

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.

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

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!

AC Savings Start Now – Prevent Future Problems with Proactive Action

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

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

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.
