5) Check certifications. Many HVAC professionals belong to the Air Conditioning Contractors of America (ACCA) or the Sheet Metal and Air Conditioning Contractors’ National Association (SMACNA). Both sites provide listings of HVAC contractors by area. Look for contractors whose technicians are certified by North American Technician Excellence (NATE) and partnered with ENERGY STAR.

Inside the unit, the air passes over the evaporator coil first, and is cooled and dehumidified. The now dehumidified, cold air then passes over the condenser coil where it is warmed up again. Then the air is released back into the room. The unit produces warm, dehumidified air and can usually be placed freely in the environment (room) that is to be conditioned.
"Highly recommend! From the time I contacted them to make an appointment, to them showing up, troubleshooting the issue with my a/c unit, them verifying my warranty and driving to Grapevine to get the part, then back to Fort Worth to install it was LESS than 24 hours. Outstanding service, price and knowledge. I will only use this company from now on. Would give ten stars if possible."
Central air conditioners are more efficient than room air conditioners. In addition, they are out of the way, quiet, and convenient to operate. To save energy and money, you should try to buy an energy-efficient air conditioner and reduce your central air conditioner’s energy use. In an average air-conditioned home, air conditioning consumes more than 2,000 kilowatt-hours of electricity per year, causing power plants to emit about 3,500 pounds of carbon dioxide and 31 pounds of sulfur dioxide.

The most important maintenance task that will ensure the efficiency of your air conditioner is to routinely replace or clean its filters. Clogged, dirty filters block normal airflow and reduce a system's efficiency significantly. With normal airflow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity. Replacing a dirty, clogged filter with a clean one can lower your air conditioner's energy consumption by 5% to 15%.

Modern refrigerants have been developed to be more environmentally safe than many of the early chlorofluorocarbon-based refrigerants used in the early- and mid-twentieth century. These include HCFCs (R-22, as used in most U.S. homes before 2011) and HFCs (R-134a, used in most cars) have replaced most CFC use. HCFCs, in turn, are supposed to have been in the process of being phased out under the Montreal Protocol and replaced by HFCs such as R-410A, which lack chlorine.[14] HFCs, however, contribute to climate change problems. Moreover, policy and political influence by corporate executives resisted change.[15][16] Corporations insisted that no alternatives to HFCs existed. The environmental organization Greenpeace provided funding to a former East German refrigerator company to research an alternative ozone- and climate-safe refrigerant in 1992. The company developed a hydrocarbon mix of isopentane and isobutane, but as a condition of the contract with Greenpeace could not patent the technology, which led to its widespread adoption by other firms.[17][18][19] Their activist marketing first in Germany led to companies like Whirlpool, Bosch, and later LG and others to incorporate the technology throughout Europe, then Asia, although the corporate executives resisted in Latin America, so that it arrived in Argentina produced by a domestic firm in 2003, and then finally with giant Bosch's production in Brazil by 2004.[20][21]

Heat pumps and electric furnaces usually have steam humidifiers to increase output. They are line voltage powered and must be unplugged or disconnected before servicing to avoid injury. With the exception of some mist type humidifiers, all have a reservoir. Stagnant water sitting in the reservoir during the off season can be a breeding ground for bacteria. Turn the water off and clean the humidifier if possible when heating season has ended.
If your air conditioner is old, consider buying an energy-efficient model. Look for the ENERGY STAR® and EnergyGuide labels — qualified central units are about 15% more efficient than standard models. New residential central air conditioner standards went into effect on January 1, 2015; see the efficiency standards for central air conditioners for details, and consider purchasing a system with a higher SEER than the minimum for greater savings.

While it should be rare to have problems occur with new equipment, it does happen. When it does, you want a good troubleshooter who is knowledgeable and can make the diagnosis and repair in a timely and efficient manner. That means you want that HVAC contractor who sends their technicians to HVAC technical seminars and factory sponsored training classes. That can make the difference between solving the problem quickly and efficiently in hours or being frustrated waiting days or weeks to have the problem solved. Take the time to choose your contractor wisely and it will save you a lot of heartache and frustration.

I originally took off one star because of the SNAFU with getting the part ordered. When Alberto called me on the phone he admitted the person had "gotten busy with other things" and apologized. THAT was taking the high road and I was impressed by that. Sadly, for reasons I won't guess at, Alberto has decided to take the low road in his comments and imply that they got the part as quickly as possible. Well, we called at 2:30 so did someone spend six and a half hours finding the part?? That seems very doubtful. As for the price I think my review was fair in stating what value we got for what I deemed to be a slightly higher price than others might charge. I did not take any stars off for the price, and still am not, but I am taking another star off because of Alberto's comments, which are deceptive and not the same thing he told me in person. Alberto, I suggest you stick with the high road in the future.
Take germs, for example. The majority of people attempt to avoid these dangerous airborne, illness-causing organisms with hand sanitizer or by washing their hands regularly. But did you know that a old indoor coil in your own Mableton home can expose you and your family to fungi and bacteria in your duct systems? That’s why devices like the Ultraviolet Germicidal Light exist. They can help prevent the accumulation of germs in your home and allow you to breathe in clean air. Call us for a complimentary, in-home estimate to find out how we can install one of these in your duct system.
In modern buildings, the design, installation, and control systems of these functions are integrated into one or more HVAC systems. For very small buildings, contractors normally estimate the capacity and type of system needed and then design the system, selecting the appropriate refrigerant and various components needed. For larger buildings, building service designers, mechanical engineers, or building services engineers analyze, design, and specify the HVAC systems. Specialty mechanical contractors then fabricate and commission the systems. Building permits and code-compliance inspections of the installations are normally required for all sizes of building.

In 1992, a non-governmental organization, Greenpeace, was spurred by corporate executive policies and requested that a European lab find substitute refrigerants. This led to two alternatives, one a blend of propane (R290) and isobutane (R600a), and one of pure isobutane.[18][22] Industry resisted change in Europe until 1993, and in the U.S. until 2011, despite some supportive steps in 2004 and 2008 (see Refrigerant Development above).[27][67]


Engineers have pointed out some areas where efficiency of the existing hardware could be improved. For example, the fan blades used to move the air are usually stamped from sheet metal, an economical method of manufacture, but as a result they are not aerodynamically efficient. A well-designed blade could reduce electrical power required to move the air by a third.[25]
Does your home's temperature need a little adjusting? An HVAC contract is a document that establishes your agreement with the contractor you hire to fix or maintain your heating, ventilation and air conditioning systems. It's best to create a free HVAC contract before the work has even begun. We'll help you take down the details of your project so work can begin and your place will get back to a comfy temperature, fast.

James Harrison's first mechanical ice-making machine began operation in 1851 on the banks of the Barwon River at Rocky Point in Geelong, Australia. His first commercial ice-making machine followed in 1853, and his patent for an ether vapor compression refrigeration system was granted in 1855. This novel system used a compressor to force the refrigeration gas to pass through a condenser, where it cooled down and liquefied. The liquefied gas then circulated through the refrigeration coils and vaporized again, cooling down the surrounding system. The machine produced 3,000 kilograms (6,600 lb) of ice per day.[citation needed]

Alberto said they were busy but could either install on the upcoming Saturday.  We were going to be out of town and said unfortunately that day did not work.  He then proposed the upcoming Tuesday as a possible solution, but just had to confirm with another appointment.  I said great.  I will review the estimate and call your office to confirm I want to move forward with the install.
They were quick to come out and diagnose the problem with my furnace, but I thought the estimate of $549 a bit high to replace the circuit board.  So called around and found Leo's Appliance in Concord that sells appliance parts and the circuit board was only $90.49 - that is the retail cost to me, so I imagine the wholesale cost is a lot less.  So BEWARE of this company since they wanted $500!!! to replace the circuit board which is located right in the front of the furnace - extremely easy to access.  I hate it that you cannot trust repair companies.
Heaters are appliances whose purpose is to generate heat (i.e. warmth) for the building. This can be done via central heating. Such a system contains a boiler, furnace, or heat pump to heat water, steam, or air in a central location such as a furnace room in a home, or a mechanical room in a large building. The heat can be transferred by convection, conduction, or radiation.
HVAC equipment is estimated to last about 15 to 20 years. Yet over the years, parts go out and need to be repaired. Heat sensors, exchangers, and ducts can become worn out. Air conditioning motors may need repairing from time to time. For repairs to your heating and air conditioning systems, and even general maintenance, let HomeAdvisor help.
