Removing Mold from a Window AC Unit

Mold is one of the worst problems a homeowner can encounter. Mold can be difficult to find, and often hides in dark, damp places, leaving homeowners unaware of its existence until it becomes a serious problem. Once that happens, it can often be so out of hand that it requires an expert to get rid of. The best way to prevent mold growth in your home is to regularly check areas that may be prone to leaks or excess moisture, to see if mold is growing there, including your window AC unit. Check out these steps for how to check and clean mold from your window air conditioner unit.
 

Mold likes to grow in dark, damp places and can cause serious health issues. One of the places it can thrive is inside your window AC unit. If you start experiencing allergy symptoms, a musty smell coming from your window AC, or visible mold on the unit, it might be time to clean it out.

AC MOLD REMOVAL STEPS

Before starting, make sure the area you're working in is well-ventilated to prevent any issues caused by fumes from bleach, cleaning products, etc.
 

1. Put on some old work clothes that you don't mind getting dirty, as well as your mask, gloves, and protective eyewear.
2. Turn off and unplug the AC unit.
3. Take the front grill off the unit by unclipping it or unscrewing any screws (if applicable).
4. Remove the filter. If disposable, throw it away. If washable, put the filter in a sink or tub and sprinkle with powdered detergent. Cover the filter with hot water and let it soak for 15 minutes, then scrub it clean, rinse out with fresh water, and allow it to dry fully.
5. Next, remove the metal cover from behind the front grill by lifting it upwards. Use your vacuum to remove as much dust as you can.
6. If you see mold, try to wipe it away with a cloth.
7. If it doesn't wipe away easily, dilute ½ cup bleach and 1 tablespoon in 3 gallons of hot water. Being careful not to get the mixture on your skin or in your eyes, use a cloth, sponge, or scrub brush to clean stubborn mold inside your AC unit and on the front grill.
8. Let the mixture sit on the mold for 10 minutes before rinsing with clean water and drying with a clean cloth.
9. Once everything is completely dry, you can reassemble your AC unit and plug it back in.
