In the heat of summer, one of life's pleasures is to come home to an environment that is refreshingly cool and comfortable. Air conditioning units perform this function by drawing hot air out and passing it over an evaporator coil. The evaporator coils contain a refrigerant called Freon, which changes from a liquid state to a gaseous state when it absorbs hot air. The refrigerant is then pumped to an outside coil called the condenser because this is where the liquid gives up its heat and returns to a liquid. A compressor is responsible for moving the refrigerant between the two coils and for changing the pressure, ensuring that the refrigerant either evaporates or condenses in the correct coils.

Air conditioning units are complex appliances dependent on a variety of conditions to perform properly. There are few things that can go awry with air conditioning units that will require commercial air conditioning repair. Air conditioners are sized according to "load" (which is the amount of heat lost or gained in the home); they are designed to have a given amount of "charge" or refrigerant and to have a given amount of air flow across the coils. A change or disruption in these parameters will cause air conditioner problems requiring AC Repair Buford. Common problems that can occur are:

Faulty Ducts � Faulty ducts are the primary waste of energy in a home. Leaking ducts can drain upwards of 40% of the energy out of an air conditioner. Ducts are held together with duct tape (of course) which eventually dries out and falls off. Leaky duct work wastes cooled air and allows contaminates to enter the home such as odors, moisture, and allergens. A professional HVAC technician from a company such as comfort control Inc can seal the ducts to ensure proper function.

Dirty Coils and Filters� To properly absorb heat the evaporator coils have to be cold and free of dirt. In addition, the coils require a certain amount of air to pass over them to perform adequately. Filters that become clogged reduce this air flow to a level below its design level in turn forcing the unit to struggle to keep up, eventually shortening the unit's life expectancy.

Leaking Water � Air conditioners have a plastic or rubber drain tube that directs excess condensation to a floor drain or condensate pump. If water is pooling at the base of the AC unit it could be caused from either a leaking tube, a blocked tube or the condensate pump has failed.

Doesn't Blow Air � If the motor runs but the system does not blow air it could be a broken belt. Other possibilities are that the thermostat was accidentally switched to off or heat, or electricity is not reaching the unit.

Air Conditioning Repair Buford not only repairs AC units they also offer yearly maintenance packages. Maintenance programs lower energy costs and extends the life of the unit. The system will run an average of 25% more efficiently with annual maintenance.
