Evaporator coils should be cleaned at least once a year. By keeping them clean, you will also minimize energy usage and reduce utility costs. It is estimated that dirty evaporator and condenser coils can increase the energy usage of your AC system by over 30 percent!

What happens when evaporator coils are dirty?

Drop in cooling efficiency: Dirt along a coil creates a layer of insulation between the air and the refrigerant in the coil. The ice can also cause damage to the fins and coil from warping. Clogged condensate drain: As the evaporator coil absorbs heat, it also causes moisture to condense along it.

Does evaporator coil cleaner work?

Alkaline-based coil cleaners are also very effective, fairly safe, and offer excellent cleaning results in most all conditions, on both condenser and evaporator coils. These cleaners usually produce a mild odor, if any, while effectively removing foreign materials from the surface of the coils.

How do you clean an evaporator coil without removing it?

Use a compressed air canister. One of the best ways to get the dirt and other debris out is to use compressed air. Blow the air into the coil to loosen the dirt. If there’s stubborn dirt, though, you might need to put the nozzle close to the bottom of the debris, along its side.
