Servicing Your HVAC System

Regular air conditioning service and repair maximizes system efficiency, extends the system's life, and cuts energy expenses while enhancing the comfort and indoor air quality of your house. The question is, exactly how frequently should you schedule air conditioning service and repair to increase system efficiency?

Heat pumps offer an energy-efficient alternative to heaters and air conditioners for climates with moderate heating and cooling demands. Like your freezer or fridge, heat pumps use electricity to move heat from a cool space into a warm space, making the cool space cooler and the warm space warmer. During the heating season, heat pumps move heat from the cool outdoors into your warm house; during the cooling season, heat pumps move heat from your cool house into the warm outdoors. Because they move heat rather than generate heat, heat pumps can easily deliver up to 4 times the amount of energy they consume.

Central air conditioners circulate cool air through a system of supply and return ducts. Supply ducts and registers carry cooled air from the air conditioner to the house. This cooled air becomes warmer as it circulates through the house; then it flows back to the central air conditioner through return ducts and registers.

For maximum efficiency, qualified air conditioning service and repair should be arranged yearly. During a maintenance call, your air conditioning service and repair professional should inspect all parts of your system and make repairs and modifications as needed.

According to the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy, heating and cooling accounts for about 43 percent of the energy usage in a common traditional home, making it the leading energy expense for most people.

Throughout the second half of the 20th century, nearly all air conditioners utilized chlorofluorocarbons (CFCs) as their refrigerant, but, due to the fact that these chemicals are damaging the planet's ozone layer, CFC production stopped in the United States in 1995. Nearly all air conditioning systems now utilize halogenated chlorofluorocarbons (HCFCs) as a refrigerant, but, these are also being gradually phased out, with most production and importing stopped by 2020 and all production and importing stopped by 2030. Manufacturing and importing of today's main refrigerant for home air conditioners, HCFC-22 (also called R-22), will begin to be phased out in 2010 and will cease entirely by 2020. However, HCFC-22 is anticipated to be readily available for several years as it is recovered from old systems that are taken out of service. As these refrigerants are phased out, ozone-safe hydro fluorocarbons (HFCs) are anticipated to prevail over the market, as well as alternative refrigerants.

The greatest time to service an air conditioner is before it's actually needed. This is the smartest thing to do. Routine upkeep and cleaning is extremely crucial. Replace the filter monthly. Aside from the routine filter, there are other ones that can be utilized, but, check with an air-conditioning maintenance person before you do anything.Phoenix AZ Air Conditioning Service\n
