Understanding Central Air Systems

Central air systems can be categorized into split systems and packaged systems. Split systems have components located both inside and outside the home. The indoor unit contains the evaporator coil, while the outdoor unit houses the compressor and condenser. On the other hand, packaged systems have all components housed in a single unit placed outside the home.


Central air systems operate by circulating cool air through a system of supply and return ducts. The process begins when warm air from inside your home is drawn into the return ducts. This air then passes through the central air conditioner system’s evaporator coil, where it is cooled and dehumidified before being distributed back into your home through the supply ducts.


The central air conditioning system uses refrigerant to absorb heat from the warm air inside your home. This refrigerant is pumped between the indoor and outdoor units, transferring heat from one to the other. As a result, the cooled air is circulated throughout your home, maintaining a comfortable temperature.
