Always turn off the power before cleaning the outdoor unit.

Then, slide the unit out from the wall. If your air conditioner’s outdoor unit is mounted on a window, remove the mounting frame and cover. Pay attention to the position of the screws so you can reassemble them in their original places.

Clean the Fins

Use a fin comb to brush away the dirt and straighten any bent fins. Simply align the comb’s serrated edges with the surface of the fins and pull them straight. Wear leather gloves to protect your hands from cuts.

Clean the Condenser Coils

The condenser coils will be covered in dirt and dust. After brushing away the initial layer of dirt with the fin comb, use a vacuum cleaner to thoroughly remove all the remaining dust and debris.

The condenser coils will be caked with dirt and dust. After using the fin comb to remove the initial layer of grime, use a vacuum cleaner to ensure that all the dust is gone.

However, to thoroughly clean the condenser coils, you’ll need to use specialized cleaning agents or soap.

Clean the Condenser Fins

Pour a specialized cleaning agent or soap over the entire surface of the condenser fins and use a hose to spray water directly onto them to create a foamy lather. Use a soft cloth or the fin comb to wipe away any remaining dirt.

Clean the Fan Motor’s Fan Blades

Use a soft cloth to wipe away any dirt or dust from the fan motor’s fan blades. If the fan motor’s bearings have plastic or rubber oil ports, open them and add a few drops of electric motor oil. Then, clean or replace the air filter and reassemble the outdoor unit.
