How To Find & Remove Mold From Your Air Conditioner

Mold. You’ve seen it on old loaves of bread, you’ve probably seen it on rotten cheese or fruit and you may have even noticed it in your shower stall or bathtub. But did you know mold is likely also lurking in your air conditioner? Just think, air conditioners are mainly used when temperatures are on the rise and when the house or apartment feels warm and sticky, right? Well, those conditions are the perfect breeding grounds for mold spores. So, how can you tell if mold is growing in your air conditioner and what can you do to remove it safely? Find out below!

You’re going to need a few tools and supplies for the job, so before you get started, make sure you’ve got the following ready to go:

  • Protective goggles or glasses
  • A face mask
  • Gloves
  • Water
  • Laundry detergent and bleach
  • Dish soap
  • A large bucket and a cloth
  • A scrub brush
  • A screwdriver
  • A vacuum cleaner with multiple attachments

Now, let’s get started.

Make sure you’re wearing all of the protective gear mentioned above and then make sure the air conditioner is turned off and that it’s unplugged from the outlet or power source.

Remove the front grille by pulling it forward and slightly down. If it’s screwed in on your model, use the screwdriver to remove the screws and then remove the grille.

Once the grille is removed, you’ll find the filter. We recommend replacing the filter if yours is disposable and if it’s not, rinse it in the sink with warm water and laundry detergent. Give it a good scrub with the scrub brush and then let it air dry.

While the filter is drying, head back to the air conditioner and remove the metal cover behind the grill. Vacuum out all dirt and debris and wipe away any visible mold (little black specks).

Mix ½ cup bleach, 1 tablespoon of dish soap and 3 gallons of hot water in a bucket. Then use a cloth or sponge to scrub the moldy areas of the unit (including the grille) and once all is removed, give it a once over with a clean damp cloth.

Let the unit dry completely before reinstalling the parts and you should be good to go! Enjoy that fresh, clean, cool air!
