What Is an Evaporator Coil?

| My HVAC Price

An evaporator coil is a vital component in an air conditioning or heat pump system. It’s located indoors and is responsible for absorbing heat from indoor air, allowing the refrigerant to evaporate and cool the air before distributing it throughout the space.

The concept of the evaporator coil emerged with the development of air conditioning technology. As air conditioning systems evolved, engineers sought efficient ways to transfer heat and achieve the desired cooling effect.

The design of evaporator coils has become more sophisticated over time, with advancements in materials and refrigerant technology. Modern coils are designed to maximize heat transfer efficiency while minimizing energy consumption.
