Size of System
Oversized System: Bigger is not definitely not better. Oversized
systems are prone to short cycling or turn on and off frequently and will
reduce the life expectancy of the equipment. In addition, the
ideal comfort level of the home will not be obtained because of dramatic
changes in the temperature of the house as the house cools and heats rapidly.
Finally, an oversized system will not properly dehumidify the air due to the
short cycling, which can cause swamp-like conditions (cool but humid air).
Maintenance
Air conditioning systems should be serviced every year at the beginning
of the cooling season. The exterior compressor/condenser units should be
kept clean and free of all leaves and debris; they should never be covered
or otherwise boxed-in, and shrubs and hedges should be cut back. All of the
above restricts the free flow of air, which reduces the gas-to-liquid
process and overall efficiency of the system. In extreme cases, this may cause
damage to the compressor. Window units should be removed during the heating
system, because they allow an excessive amount of heat loss when they are
left in.
Evaporator Coil
Though usually made of copper, these coils can corrode as the system
ages.
Compressor
The compressor is the main mechanical component of a central air conditioning
system, which both compresses the freon and moves the freon through the
system. In general, air conditioning compressors should not be operated
in temperatures below 60 degrees F, or damage may result.
