Cros s town Plum bing Presents How the Central Cooling<br />
Sy s tem Works<br />
<strong>www</strong>.<strong>crosstownplumbing</strong>.<strong>com</strong>
No matter how hot or humid it is outside, central air<br />
conditioning plays an important role in keeping your home<br />
cool and reducing humidity levels indoors.<br />

CENTRAL COOLING UNIT<br />
Central cooling air units are split systems <strong>com</strong>prised of an<br />
outdoor unit, also called the condensing unit and an indoor<br />
unit, also called the air handler.<br />

CENTRAL COOLING BASICS<br />
The function of a central cooling air unit is to transport heat<br />
from one station to another. The vehicle your system uses to<br />
carry the heat is called a refrigerant, <strong>com</strong>monly referred to as<br />
Freon.<br />
<strong>www</strong>.<strong>crosstownplumbing</strong>.<strong>com</strong>
AIR CONDITIONER COMPRESSOR<br />
The <strong>com</strong>pressor in your outdoor unit changes the refrigerant<br />
or Freon into a high temperature, high pressure gas. As that<br />
gas flows through the outdoor coil, it loses heat and<br />
condenses into a high temperature, high pressure liquid.<br />

EVAPORATOR COIL<br />
Evaporator coils are located within the air handler or furnace<br />
and are responsible for absorbing heat. The liquid refrigerant<br />
goes through copper tubing into the evaporator coil where a<br />
sudden expansion turns the refrigerant into a low<br />
temperature, low pressure gas.<br />

AIR CONDITIONER DUCT WORK<br />
Inside your home, the low temperature, low pressure gas<br />
soaks up heat from the air circulating in the duct work. The<br />
cooled down air is then distributed back through your house.<br />

COPPER TUBING<br />
This connects the <strong>com</strong>pressor, the condenser, the metering<br />
device, and the evaporator. The heat that was absorbed by<br />
the refrigerant is transported back outside through copper<br />
tubing and released into the outside air.<br />

COOLING SYSTEM TUNE-UP<br />
Dirty coils and improper refrigerant levels can cause your<br />
system to cool less efficiently than it should. It forces your<br />
<strong>com</strong>pressor to work harder than is necessary and can actually<br />
shorten the life span of your cooling unit. We re<strong>com</strong>mend<br />
having an annual cooling system tune-up by a licensed<br />
technician.<br />
