How To Prevent Mold In An AC Unit


Mold in your air conditioner can be a major problem. Not only does it create a musty smell in the home each time the AC turns on, it can also lead to allergies and breathing problems for everyone living in the house. Mold occurs because there are many components inside an AC unit that are exposed to moisture. Fortunately, you can also take steps to easily prevent and remove the mold. The following tips can help.

Tip #1: Change the filter more often

Check your filter every couple of weeks if you are noticing a musty odor. In humid climates, moisture and mold spores can get trapped on the filter, which then leads to mold growth. If you are concerned about the extra costs, invest in two reusable filters. This way, you can remove, wash, and leave one to dry while the other is installed into the unit.

Tip #2: Clean the drip tray

The drip tray sits beneath or to the side of the unit, with a hose from the unit going into the tray. While mold in the drip tray or drainage hose won't enter the home, the spores can become airborne and get sucked into other parts of the unit. Washing the tray out with a diluted bleach solution will kill any mold in the tray. The hose should also be removable, which will allow you to flush it out with the bleach solution as well.

Tip #3: Check the blower

Spores that begin growing inside the blower will spread through the entire houses. To clean the blower, you will need to cut power to the unit and then remove the outer covering on the unit. You can then wipe down the blower, both inside and out, with the diluted bleach solution. While you are inside the unit, take a few minutes to wipe down the condenser coils and the inside of the case to further eliminate mold spores.

Tip #4: Go ultraviolet

In very moist climates or if you have an ongoing mold issue with your unit, an ultraviolet light might be the solution. UV light prevents mold and mildew growth. There are UV light units that can be installed inside of your AC to prevent any mold growth. These lights are wired into the AC unit's power source, so they will run on their own without any input from you. Contact an HVAC technician in your area for help.
