Evaporator Coils: How They Work and Cleaning Tips - Trane

An evaporator coil is the component of your heat pump or air conditioner that absorbs the heat and moisture from the air inside your house. It works alongside the condenser coil to produce cool air and complete the heat exchange cycle. Warning: Your air conditioner is a dangerous, high-voltage device. Touching or mishandling the internal ...
