What does an evaporator coil do in an air conditioning system?

The role of an evaporator coil in an air conditioning system is crucial to the cooling process. It absorbs heat from the indoor air, which lowers the air temperature in the living space. As the warm air from indoors is blown over the evaporator coil, the coil is cold due to the refrigerant flowing inside it. This refrigerant evaporates as it absorbs heat, changing from a liquid state to a gas.

This heat exchange process effectively cools the air that is circulated back into the living space, creating a comfortable environment. By absorbing heat from the indoor air, the evaporator coil contributes significantly to the overall cooling effect produced by the air conditioning system. The process is essential for maintaining low indoor temperatures and ensures that the air conditioning system operates efficiently.
