How to Clean Evaporator Coils

Cleaning your evaporator coil helps your air conditioner or heat pump system work efficiently and can also prolong its life. It’s normally attached to your furnace, and we recommend having it cleaned each year before heating season begins, but it’s ideal to repeat mid-season. Although some homeowners might try to clean their evaporator coil themselves, this service is best handled by a trained Carrier HVAC technician.

How to Clean Evaporator Coils

These are the steps that your Carrier expert may complete:

  • Turn the air conditioner or heat pump and furnace off and wait until they have cooled down.
  • Remove the access panel to expose the coil.
  • Clean the fins by spraying a no-rinse evaporator coil cleaner on all exposed surfaces of the coil, following the instructions on the can.
  • Check the drain pan for signs of bacteria or mold. If there is minor growth, clean with a 50/50 mix of bleach and water.
  • Check that the condensate drain tube is working properly by pouring water in the tube.
  • Check the coil and reapply the cleaner on any areas that are not fully cleaned from the first application.
  • Replace the panel when finished cleaning the coils.
  • Turn the HVAC system power back on.
