The coil is the unsung hero of any home heating or cooling system. Assure your system reliability and efficiency with a matched Trane indoor coil. It's 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 is a series of piping connected to a furnace or air handler that blows indoor air across it, causing the coil to absorb heat from the air. The cooled air is then delivered to the house through ducting. The refrigerant then flows back to the compressor (a compressor controls the pressure applied to the refrigerant) where the cycle starts over again.
