Aplus Heating & Air

Air Conditioning Systems - They are designed to cool the air in a home using a refrigerant such as Freon to transfer heat from indoors to outdoors. This refrigerant circulates through a closed-circuit loop of copper tubing that runs between an outdoor coil - called a condenser, and an indoor coil - called an evaporator.

A Forced-Air Heating System - This system is designed to have a blower in the furnace pull cool air in from rooms through ductwork. The air then passes through a metal "heat exchanger" where it's heated by the burner that's located inside a combustion chamber. Gas is mixed with air and then ignited by a pilot light, a spark or a similar device controlled by a thermostat. The system then blows the warm air back into rooms through the ductwork. Exhaust gasses from the burners are vented outside through a flue. With older "gravity" furnaces, the heated air is delivered by natural convection, not by a blower.

Air Cleaners - Though dust is most noticeable where it settles and collects, the average house has about 3 million dust particles suspended in every cubic foot of air. For allergy sufferers, asthmatics, people with bronchial problems and those who are hyper-sensitive to airborne particulates, this can be a real problem. Air cleaners and filters are designed to remove dust from the air. Air cleaners are made as self-contained, tabletop or room-size appliances that serve small areas or single rooms, or they may be in the form of whole-house filters that attach onto a house's forced-air furnace. They work by mechanical filtration, electrical attraction or a combination of the two methods.
