How to Clean a Window AC Unit
1. Unplug the Unit
Before diving into the cleaning process, always unplug the AC unit to ensure safety.
2. Remove and Clean the Air Filter
Consult the user manual for guidance on removing the filter and use a handheld vacuum or soft-bristle brush to remove debris. Soak the filter in lukewarm, soapy water, rinse it thoroughly, and allow it to air dry completely before putting it back in the unit.
3. Clean the Grille Cover
Open or remove the grille cover using manufacturer instructions. If you can, rinse it under cool water or submerge it in soapy water, cleaning between vent slats with a soft-bristle brush, sponge, or dishcloth. Dry the cover before reinstalling. If you can't remove it, dust the surface using a handheld vacuum, vacuum fitted with a dusting attachment, or a microfiber cloth. Then, apply all-purpose cleaner to a clean cloth and wipe down the grille cover.
4. Clean Coils and Fins
Gently remove dust and debris from the evaporator coils and fins using a soft-bristle brush. Spray the coils and fins with compressed air to dislodge and remove buildup. Be careful not to damage the coils and fins during cleaning.
5. Clean the Exterior and Reassemble
Wipe the exterior top and sides using a damp microfiber cloth to remove dust. If the unit has a drip tray, clean it too, then dry the components thoroughly before reassembling.
Removing Mold and Mildew from a Window AC Unit
Always wear protective gear when handling a moldy or mildewy AC unit to avoid spore inhalation.
1. Remove the AC Unit from the Window
Wear household gloves, a face mask, and eye protection to keep your skin and respiratory system safe.
2. Remove and Clean or Replace the Filter
Remove the filter and either replace it or soak it in a bleach solution for 10 minutes before rinsing and air drying.
3. Clean the Air Conditioner Components
Use the bleach solution to clean the unit's parts, being careful to avoid electrical components. Dry the unit completely before reassembling and reinstalling.
