Fan Coils San Diego

The coil, also known as an evaporator coil or an indoor coil, is the unsung hero of any home heating or cooling system. Its job, heat transfer, is one of the most important factors in achieving heating and cooling efficiencies that keep your home comfortable all year long.
 
An evaporator coil, or indoor coil, is located indoors and is either installed with your furnace or as part of your air handler. Inside the coil, the refrigerant evaporates as it absorbs heat from the indoor air that passes over it. The coil essentially serves as a “heat exchanger,” working with your heating system in the winter and your cooling system in the summer.
