An air conditioner cools with a cold indoor coil called the evaporator.

The condenser, a hot outdoor coil, releases the collected heat outside. The evaporator and condenser coils are serpentine copper tubing surrounded by aluminium fins. A pump, called the compressor, moves a refrigerant between the evaporator and the condenser.

The liquid refrigerant evaporates in the indoor evaporator coil, pulling heat out of indoor air and thereby cooling the surrounding area.

The hot refrigerant gas is pumped outdoors into the condenser where it reverts back to a liquid, giving up its heat to the outside air flowing over the condenser's metal tubing and fins.



Air conditioner filters


Clogged, dirty filters block normal air flow and reduce a system's efficiency significantly. With normal air flow obstructed, air that bypasses the filter may carry dirt directly into the evaporator coil and impair the coil's heat-absorbing capacity.

Keeping the filter clean can lower your air conditioner's energy consumption by 5-15 per cent. Most filters require cleaning every month or two during the cooling season.

Filters may need more frequent attention if the air conditioner is in constant use or is subjected to dusty conditions.
