Evaporator Coils vs. Condenser Coils
The evaporator coil is the part of an air-conditioning system that removes heat and moisture from indoor air to cool it. The condenser coil takes that heat and releases it outside.
How Do the Evaporator Coil and Condenser Coil Work Together?
Refrigerant enters the evaporator coil from through copper tubing that is connected to your outdoor unit. Once inside, it absorbs the heat from the air blowing over it. Moisture in the air is condensed into water on the coils, which then empties into the drain pan. Removing this moisture lowers the temperature of the air blown into your home, creating a more comfortable environment.
The now-warm refrigerant flows to the outdoor unit. The refrigerant then runs through the condenser coil, where the heat is expelled to the outdoor air. The refrigerant then travels back inside to the evaporator coil to repeat the process.
