Why You Should Clean Your Evaporator Coils

How to Clean Evaporator Coils | Dirty Evaporator Coils | Engineered Air

The evaporator coils are an integral part of your air conditioning system—but in order for them to function properly, they need to be cleaned from time to time. In fact, by not cleaning the evaporator coils, you run the risk of damaging your entire air conditioning system. Here’s everything you need to know about this small-yet-important component of your air conditioning system and how you can keep them functioning for years to come:

What are Evaporator Coils?

If your home is cool and comfortable right now, you can partially thank the evaporator coils. The evaporator coils in your air conditioning system work by transferring heat from the inside of your home, to the outdoors. This transfer takes place as the coolant inside of the evaporator coils evaporates. Since the evaporator coils are typically made of copper, they conduct heat quickly, which speeds up the cooling process. As this happens, the evaporation acts as a heat sink for the air that moves across the blower and ultimately helps to cool your home.

Why Cleaning the Evaporator Coils is So Important

The evaporator coils must be kept clean in order to transfer heat. Over time, dust and debris can collect on the evaporator coils and prevent warm household air from reaching the chilled metal. Not only can dirty evaporator coils cause a reduction in heat transference, but they can decrease overall cooling capacity while increasing energy consumption. Moreover, dirty coils can increase operating pressures and temperatures, which can lead to wear and tear on the system and a reduction in life expectancy.

How to Clean AC Evaporator Coils

Luckily, cleaning the evaporator coils can be done at home with a little know-how. If you do opt to clean your evaporator coils yourself, here’s how you can do it:

  • Turn off the power – Start by turning off both the air conditioner and thermostat and cut the power supply to the air handler.
  • Access the panel – The evaporator coil access panel needs to be removed in order to access the coils and start the cleaning. You can remove the panels with a socket wrench.
  • Mix your solution – There are many commercial cleaners on the market, but you can simply mix warm water and a basic detergent in a spray bottle to clean the coils.
  • Apply – After you’ve mixed your solution, apply the mixture on the coils and allow it to sit for a few minutes.
  • Wipe away – Once the mixture has sat for a few minutes, use a soft cloth to wipe away loosened debris.
