How Does that Air Conditioning System Work Anyway?

AIR HANDLER / EVAPORATOR COIL

Uses the refrigerant from the compressor (1) to cool the warm air that came from the blower motor (2). Now the cooled air comes out of a supply (B) and into your home

OUTDOOR COILS AND FAN

Expels heat from the refrigerant that warmed up in the evaporator coil (3) to repeat the cycle all over again

BLOWER MOTOR

Pulls hot air from inside your home from a return (A) and sends it to the evaporator coil (3)

SUPPLY

Cold air from the evaporator coil (3) comes out here.

RETURN

Warm air from inside the house enters here and heads to the blower motor (2)

CONDENSER

With help from the compressor, it pumps cool refrigerant fluid to the air handler/evaporator coil (3) and back in a continuous loop
