Evaporator vs Condenser.pdf

In the muggy Michigan summers, a problem with your air conditioner’s evaporator or condenser coils could leave you very uncomfortable. Knowing how each of your coils work, however, can help you troubleshoot the problem for DIY or professional service.

1. EVAPORATOR
CONDENSERVS
The evaporator coil is
located indoors, inside or
near your air handler.
This set of pipes is bent
into continuous U-
shapes and place
behind many small, thin
metal strips called fins.
Right before the
evaporator coil is an
expansion valve. This
valve receives high-
pressure liquid
refrigerant from the
outdoor condenser
It relieves the pressure
on the refrigerant, further
cooling it. The cold liquid
refrigerant then flows
into the evaporator
coil.As your air handler’s
blower fan blows air
across the coil.
Your condenser coils are
inside your outdoor unit
along with the
compressor and related
pipes and valves.
Hot, gaseous refrigerant
flows from the evaporator
to the compressor, which
pressurizes the gas and
sends it to the condenser
coils.
As the hot refrigerant
gas flows through the
pipes of the condenser
coils, the outdoor unit’s
fan blows air across the
coil.
This cools the refrigerant,
so it condenses back
into a liquid. The liquid
refrigerant flows through
copper pipes back into
the house to start
another cooling cycle
and remove more heat
from your home.
