What Is an Evaporator Coil?

If you’re like most homeowners, chances are you have minimal HVAC knowledge… and that’s ok! Learning the ins and outs of the air conditioning system isn’t usually on someone’s to-do list. However, understanding the components of your AC can come in handy. The evaporator coil for example, is a tiny piece of your air conditioner, but has a significant job to do. Moreover, knowing what the evaporator coil does and how to keep it running efficiently can help keep you cool year round. Here, we’ll teach you what the evaporator coil is and how it helps to keep you comfortable.

Evaporator Coil 101

The evaporator coil is an essential component of every air conditioning system. Evaporator coils work to absorb heat as it passes through the air conditioning unit during the refrigeration cycle. During this cycle, chilled refrigerant is passed to the evaporator coil, which then converts the refrigerant from a liquid to a gas. As this happens, the fan motor is signaled to turn on, which will begin to blow cool air throughout your home or building. Once the refrigerant is sent through the condenser unit, it is converted back to its original liquid form and the process begins again.

How to Keep the Evaporator Coil Working Efficiently in Your Air Conditioning System

Just like any appliance or large investment, your air conditioning system will require a little maintenance from time to time. If not properly maintained, the evaporator coil can become dirty and create a variety of issues like insufficient cooling and heating. The most efficient way to stop this from happening is to make sure the evaporator coils are regularly cleaned. Luckily, cleaning the evaporator coils is something you can easily do yourself with a few simple steps.

How to Clean Evaporator Coils

1. Turn off the power to your air conditioning system

2. Locate the panel where the evaporator coils are housed

3. Combine warm water and cleaning detergent in a spray bottle and apply the solution to the coils

4. Let the solution sit on the coils for five to 10 minutes before gently wiping away the debris with a cloth
