Instructions
Clean the Air Filter
Be sure to unplug a window air conditioner from the power source before cleaning it. Locate and eliminate the filter next. Some window units’ filters can be removed by simply pulling them out, while others might first need the front cover with a screwdriver removed. The best way to remove your AC unit’s filter can be found in the manufacturer’s manual for your specific model.
After removing the filter, use a hand vacuum to extract as much dust and debris as possible. Next, place the filter in a bucket of sudsy water with a bristle brush, and gently scrub it until it is thoroughly clean. Prior to re-installation, completely air-dry the filter.
Clean Air-Conditioner Coils and Fins
Use a toothbrush or soft-bristle brush to clean the evaporator coils and fins in your unit, which are responsible for turning hot air into cool air. Handle the coils and fins gently and cautiously to prevent breaking or harming them. Spray the coils and fins with compressed air to remove any remaining dirt and dust.
Clean the Exterior and Grill
Clean the window AC unit’s grill with a damp cloth or rag. If there is a lot of grime, clean it off as directed by the manufacturer, then immerse it in warm, soapy water while using a brush or rag to get in between the gaps in the grill. Dry the grill completely before reinstalling it.
A damp cloth should then be used to clean the window AC unit’s top and sides. If your AC has a drain or drip tray, clean those as well by emptying them and wiping them clean. Dry completely before going back to the air conditioner.
Prevent Mildew and Reassemble
Treat the exterior parts of the air conditioner where air flows through with hydrogen peroxide in a spray bottle to prevent mold and mildew. Before putting everything back together, give everything enough time to dry completely.
All that’s left to do is unwind, sit back, and enjoy your freshly cleaned AC unit as it circulates cool, fresh air throughout your house.
