How to Clean Mold & Mildew From AC Coils
- 1). Set up an ozone generator near where the AC takes in air. Position it as high or higher than the intake so that the AC will pull the ozone through it. Ozone kills mold, and can get to difficult-to-reach places. Run the ozone generator at its highest setting for a few hours.
- 2). Dry the air in the area as much as possible. Run bathroom vent fans and use a dehumidifier. Turn the AC on and let it run to dry out the room even more.
- 3). Turn off the ozone generator after a few hours and vent the area for a few more hours.
- 4). Remove the grill work on the AC unit. This may be as simple as snapping the grill off, but some designs may require a screwdriver.
- 5). Use a vacuum hose to go over the coils. This will remove loose dust particles, and any other debris that may cause mold to grow.
- 6). Spray the coils with a cleaning solution and allow it to sit for a few minutes. Go over the coils with a bristle brush, lightly dragging it back and forth to clean the coils.
- 7). Clean the coils and surface of the AC unit at least once every three months to keep mold from coming back. Wash or replace the filter, which is generally located behind the grill that covers the AC coils, every three months as well.
