While air conditioners cool the home, they also provide a degree of mold protection by removing some moisture from the air. But if the system’s indoor coil has too much condensation, then it can also create a breeding ground for mold. In addition to scheduling regular AC maintenance with an HVAC contractor, here are a few preventative steps to take.

How to Prevent Mold in Your Air Conditioner

1. Replace the Filter

Dust contributes to mold growth, so use a high-quality, pleated media filter to protect your indoor air quality. They will capture even the most minuscule particles, including mold spores. Replace the filter at least every two to three months, depending on how often you use the air conditioner.

2. Use Ultraviolet Lighting

Ask your HVAC contractor to install an ultraviolet light in the evaporator coil, which tends to accumulate moisture. The UV light will kill bacteria and mold spores.

3. Check It Regularly

Protect your system year-round by inspecting it for signs of mold growth. If you see any water around the unit, have your HVAC contractor assess it as soon as possible. The leak could be the result of anything from a damaged drain pan to low refrigerant levels to moisture buildup in the ducts. Sometimes these issues aren’t apparent until you smell a musty odor or discover water damage on the floor or ceiling; catching them quickly will prevent a more serious mold problem.
