Enrolling in a routine maintenance program, or taking care of that strange noise before it becomes a major problem, are both important things you can do for your air conditioning system. But it’s also important to know a little bit about your AC: how it works, what it’s made of, and what are its different components. We enjoy informing our clients about the air conditioning basics. In this post, we’d like to explain what an evaporator coil is, and what it does in your cooling system.

An evaporator coil is typically a pyramid-shaped unit that is made up of copper coils and aluminum fins or grilles. It is located indoors in your air handler. It facilitates an important aspect of the refrigerant cycle. As the refrigerant condenses in the outdoor unit back into a liquid, it is pumped by the compressor through the expansion valve, which controls the rate of refrigerant entering the evaporator coils. The evaporator coil works by evaporating refrigerant, which causes it to absorb heat as it cools your indoor air. This heat is then sent to the outdoor unit, and the cycle continues.
Your evaporator coil is just one part of the refrigerant cycle, but it’s incredibly important. However, it can develop problems, as with any mechanical component. For example, if you neglect to change your air filter regularly, or if your ductwork becomes blocked with debris, then your evaporator coil can actually frost over. Because the cooled air has nowhere to go, it sits in your air handler and disrupts the cycle of evaporation and condensation.
