Make Your AC Unit Last Longer

Cleaning Steps For A Window Air Conditioner's Interior

Dirt and dust particles can clog your window air conditioner's condenser coil, causing the unit to work inefficiently or take longer than usual to cool down your home's interior. The following steps will teach you how to clean your air conditioner's interior so that your unit operates efficiently throughout the warmest months of the year.

Materials

  • gloves
  • dust mask
  • wire brush
  • vacuum cleaner with hose attachment
  • coil cleaner
  • sponge
  • lint-free cloths
  • detergent
  • water
  • scrub brush with soft bristles

Take The Cover Off And Remove Loose Debris

Turn off the power to your unit. Put on a pair of gloves and a face mask to protect yourself from getting dirty or breathing in excessive amounts of dust. Remove the unit's cover. Inspect the metal grid that is located across the front of the unit. This part is the condenser coil and transfers warm air into cooler air that blows through the unit's vents. Move a wire brush swiftly over the metal to dislodge dirt and dust particles. Use a vacuum cleaner's hose to suck up the debris that was loosened.

Clean The Metal And Other Interior Parts

Spray an even coat of coil cleaner across the metal surface that forms the coil. Allow the product to foam up for a couple minutes to loosen surface dirt. Use a sponge to wipe away any cleaner or dirt that is on the metal pieces. Use a lint-free cloth to dry the coil off. Use a soapy sponge to clean other interior portions of the unit. Once they are clean, rinse away soap with a sponge that has been dipped in plain water. Dry the clean surfaces with a lint-free cloth. 

Clean The Filter And Wipe The Unit's Exterior

Slide out the filter from the back of the unit's cover. Rinse it off with a steady stream of water to remove dirt. If the filter is extremely dirty, use a scrub brush with soft bristles to loosen dirt from its surface. Wait for the filter to dry before replacing it in the back of the cover. Reattach the unit's cover. Use a damp cloth to wipe the unit's exterior. Use a clean, dry cloth when finished. 

Turn the power back on to the unit and adjust the thermostat. Cool air should steadily be blowing through the vents if the cleaning steps that you took were successful. Get into the practice of cleaning the unit's interior each year to help keep it operating properly.
