What Is An Air Conditioner Coil?
The key functionality of an air conditioning system relies on two main coils: the evaporator coil (inside the home) and the condenser coil (outside the home). Evaporator coils absorb heat from indoor air, while condenser coils release that heat outdoors. These components are vital for cooling performance and energy efficiency.
Types Of Air Conditioner Coils
Evaporator Coil
This coil is located inside the air handler or furnace, typically near the blower fan. Evaporator coils carry refrigerant that absorbs heat as warm air passes over them. Common construction materials include copper tubing and aluminum fins for better heat transfer.
Condenser Coil
Situated in the outdoor unit, the condenser coil releases accumulated heat from your home to the external environment. It endures exposure to outdoor elements, making durability a priority in its design. Condenser coils are also made of copper or aluminum, often with protective coatings.
