How Does Central Air Conditioning Work?
The typical central air conditioning
system is a split system, with an outdoor air conditioning, or "compressor bearing
unit" and an indoor coil, which is usually installed on top of the furnace in the
Using electricity as its power source,
the compressor pumps refrigerant through the system to gather heat and moisture
from indoors and remove it from the home.
Heat and moisture are removed from
the home when warm air from inside the home is blown over the cooled indoor coil.
The heat in the air transfers to the coil, thereby "cooling" the air.
The heat that has transferred to
the coil is then "pumped" to the exterior of the home, while the cooled air is pumped
back inside, helping to maintain a comfortable indoor temperature.
Central air conditioning can also
be provided through a package unit or a heat pump.

Cleaner air- As
your central air conditioning system draws air out of various rooms in the house
through return air ducts, the air is pulled through an air filter, which removes
airborne particles such as dust and lint. Sophisticated filters may remove microscopic
pollutants, as well. The filtered air is then routed to air supply ductwork that
carries it back to rooms.
- Because the compressor bearing unit is located outside the home, the indoor noise
level from its operation is much lower than that of a free-standing air conditioning
