Air duct cleaning can often go overlooked, especially when HVAC structures are hidden away in ceilings and walls. However, dirty ducts might be housing more than dust. Water vapors condense within the vents, which can sometimes result in the development of mold. As the HVAC system cycles, it spreads these spores into the air. When the mold is breathed in, it can cause health symptoms, including runny noses and severe asthma reactions. Fortunately, the following steps can reduce the chances of mold breeding in your HVAC ducts.

How to Prevent Mold Growth in Ducts

1. Reduce Humidity

Mold prefers moist environments. If the humidity in the ducts is kept below 50%, it will lessen the chances of spores taking hold.

Ensure fixtures that generate moisture, such as dryers, showers, and radiators, are well-ventilated. Keep these vents clear and have them cleaned regularly to maintain proper airflow.

Drying carpets, drapes, and furniture after cleaning will also keep humidity levels down. If moisture remains high, consider adding a dehumidifier to the HVAC system.

2. Remove Food Sources

Moisture alone isn’t enough to cause mold growth. The spores also need an organic food source, such as dirt. Arrange for regular duct cleaning to remove accumulated debris.

Keeping the system sterile starves mold spores before they spread. A professional will also be able to safely remove any mold or mildew that has already developed.  

3. Change Filters Frequently

Air filters need to be changed every one to two months to remain effective. They lose effectiveness when clogged, which means mold spores and debris can more readily enter the ducts.

Check if filters need to be changed by holding them up to a light. If the beams don’t pass through readily, it’s time for a new filter.
