Evaporator Coils 101


Evaporator coils, the winding tubes inside your HVAC unit may seem like
small potatoes, but the truth is that they have a profound impact on your
system’s ability to cool the home. In fact, the evaporator coil,
known to many as the indoor coil, is the unsung hero of any home heating
or cooling system.
AC repair leaders, Del-Air, explain your AC’s evaporator coils’ function.

Typically made of copper, steel, or aluminum because of their heat-conducting
properties, coils hold the refrigerant, which is the substance that makes
indoor air conditioning possible in the first place. This liquid is what
cools the home and removes that unpleasant humidity from the air your
family is breathing. In a properly functioning AC, a fan pushes air over
the evaporator coil. As the air hits the coil, the moisture is condensed
and distributed into a drip pan.

However, an evaporator coil’s job doesn’t stop there. After
cooling the air in the home, the refrigerant transports the air by a tube
to the outside component of the AC unit, also known as a compressor. Refrigerant
reaches the compressor as a warm vapor, and then departs against as a
hot one with higher pressure. The condenser then cools the high-pressure,
hot refrigerant vapor and changes it to a cooler liquid form, which travels
to the evaporator coil. The coil blows cool air through your ductwork
to the desired spaces in your home, and the refrigerant keeps circulating
until the set temperature on your thermostat is achieved.

Essentially, your evaporator coil acts as a heat exchanger, removing heat
from the air in the summer and adding it in the winter.
