Central Air Conditioning

The typical central air conditioning system is a split system, with an outdoor air conditioning, or "compressor bearing unit" and an indoor coil, which is usually installed on top of the furnace in the home.
Using electricity as its power source, the compressor pumps refrigerant through the system to gather heat and moisture from indoors and remove it from the home.
Heat and moisture are removed from the home when warm air from inside the home is blown over the cooled indoor coil. The heat in the air transfers to the coil, thereby "cooling" the air.
The heat that has transferred to the coil is then "pumped" to the exterior of the home, while the cooled air is pumped back inside, helping to maintain a comfortable indoor temperature.
Central air conditioning can also be provided through a package unit or a heat pump.

Central Heating

A furnace works to keep a home warm in the winter and plays a critical part in the operation of an air conditioning system.
Furnaces produce heat through the combustion of natural gas in the furnace's burner. The heat produced from this process then passes through a heat exchanger. Air from your home's return air ducts is blown over the heat exchanger, thus warming the air.
The furnace's blower then blows the warmed air into the duct work, which carries and disperses the warmed air throughout the home.
During warmer months, the blower inside a furnace continues to circulate return air throughout the home--only this time, the return air has been cooled by being blown over the indoor coil portion of the home's split-system air conditioning system. The evaporator coil is typically installed downstream of the furnace.

Heat Pumps

Using electricity as its energy source, heat pumps are used for either the heating or cooling of your home by transferring heat between two reservoirs.
In the warmer months, the heat pump acts like an air conditioner, removing heat from the air inside your home and transferring it outside.
During colder months, heat from outdoor air is extracted and transferred to the interior of your home. Believe it or not, even a 32º Fahrenheit day produces enough heat to warm a home via a heat pump.

*Remember, factors affecting your heating and cooling system include the climate in your region, humidity levels, the number of windows in your home, total square footage of your home, the type of insulation you have and the number of people that live in your residence.

What Is R-22?

R-22 is the common name for hydro-chlorofluorocarbon (HCFC). R-22 has been used as a refrigerant by HVAC manufacturers for over 40 years, but studies in the past decade have shown that HCFCs contain chlorine, an ozone-depleting agent. For this reason, the United States Clean Air Act has set a target date for January 1, 2010, on which HVAC manufacturers must cease the production of products that use R-22.

What Is R-410A?

R-410A is the common name for an emerging hydro-fluorocarbon (HFC) that is being used as a refrigerant in the HVAC industry. R-410A is more environmentally friendly than R-22 and is being seen as the most likely replacement for R-22 by HVAC manufacturers. At the beginning of 2010, the use of alternate refrigerant will be required in HVAC manufacturing.

What Is ENERGY STAR?

ENERGY STAR is a program that was created by the US Environmental Protection Agency (EPA) to help businesses and individuals make energy efficient purchases.  This program places the ENERGY STAR label, a small blue and white logo, on items that meet superior energy efficiency standards. This label provides an easy way for consumers to identify quality, high efficiency products.  For more information about the Energy Star program, please view their website at www.energystar.gov.
