How to Remove Mold from Air Ducts

For many people, the thought of mold growing in their air ducts is enough to make their skin crawl. After all, mold is not only unsightly, but it can also be dangerous to your health. If you’re concerned about mold in your air ducts, you’ll be happy to know that it is possible to remove it. With a little elbow grease and the right cleaning supplies, you can get rid of the mold and keep your air ducts clean and safe.

What You’ll Need

To clean the interior of your air vents, you’ll need a HEPA vacuum. Then, clean the interior of the air vents using a baking soda, vinegar, and detergent solution. To get deep inside the vents, you may need to use a long-handled mop. Finally, after 15 minutes, clean the mold, mildew, or dirt from your air vents using a scouring brush. That’s all there is to it!

Step-by-Step Instructions

  1. To start, vacuuming the vents with a HEPA vacuum is necessary in order to remove any large chunks of dirt or debris. If you don’t have a HEPA vacuum, any vacuum with a brush attachment will work. Just be sure to move slowly so that you don’t miss anything.
  2. Once the large pieces have been removed, it’s time to tackle the smaller ones. To do this, mix together a solution of baking soda, vinegar, and detergent. Spray this solution generously on all of the surfaces of the vent (inside and out) and allow it to sit for 15 minutes. 
  3. While you’re waiting for the solution to work its magic, fill a bucket with warm water and grab a long-handled mop. When the 15 minutes are up, dip your mop into the bucket and begin scrubbing at the vent from top to bottom until all of the molds have been removed. Rinse with clean water and repeat as necessary until all traces of mold are gone!
  4. Once you’re satisfied that the vent is clean and mold-free, go ahead and turn on your furnace or AC unit so that it can dry completely (about 30 minutes). And that’s it! You’ve successfully removed mold from your air ducts without any fuss or mess.
