As the seasons change, an increase in humidity and rainfall can mean only one thing: Spring is in the air, and mold is on the rise. Is your HVAC system prepared with an HVAC system mold growth prevention plan?  Here are 4 HVAC system mold growth prevention strategies that will make sure your HVAC system is not scattering mold spores throughout every corner of your home.

Check The Cooling Coils

HVAC system mold growth prevention tends to begin around the cooling coils, which is where a lot of condensation occurs as the air becomes dehumidified. Be sure to check the nearby draining pan as well, as this area also tends to give mold the moisture it needs to thrive.

Are There Wet Duct Linings

Sometimes water can spray onto the duct linings and cause microbial bacteria to form, so pay attention to the lining of your ventilation ducts, and treat them with anti-fungal products if necessary.

Change the Air Filter

The quality of your air is only as good as an HVAC system’s filter. When you are changing the air filter, you should always shut off the fans so that any contaminants from the old filter are not distributed throughout the house. Make sure the filter fits tightly so that there is no room for fungi to grow.

Examine the Air Intakes

The air intake is any area where outdoors air reaches the HVAC system, and It is where many environmental contaminants can enter your home. If your home is near any natural body of water, farmland, or is in close proximity to a landfill, you are especially at risk and need an HVAC system mold growth prevention plan. In addition, animal feces (usually bats or birds) on air conditioning units or window sills can increased the risk for spore contamination.
