Mold can thrive in an environment rich in organic material and moisture, with temperatures between 32-120 degrees. If you don’t take steps to prevent moisture from building up in your heating, ventilation and air conditioning (HVAC), system, such conditions can be created.
Here are some tips that will help prevent mold from HVAC systems.
- Keep the drain pans clean. Standing water will not drain through the deep seal trap. Mold growth will be caused by the water and microbes that are in the drain pans.
- Replace air filters regularly. Filters that are dirty or wet will trap mold spores, and other contaminants. If you don’t change your filters regularly, which is usually once per month, these particles can contaminate HVAC systems.
- Use an HVAC mold inhibitor. These HVAC-approved, EPA-registered mold inhibitors are designed to prevent mold and mildew growth. Follow the manufacturer’s instructions to apply the inhibitor to all components of your cooling and heating unit.
- Use a disinfectant. You must first treat the mold inhibitor with a disinfectant before you apply it to your HVAC system. You should look for a EPA-approved disinfectant labeled for HVAC systems.
- Keep ducts dry. The HVAC system might have ducts that are more prone to mold and moisture. Check your HVAC system to determine which ducts are most affected. Water-damaged parts can be replaced and ducts repaired.
- Make sure to inspect the air intakes. If your HVAC system is located near organic material accumulation areas, you should inspect the air intakes. Keep the area below your HVAC system clean by moving trash cans and removing standing water, bird droppings, etc.
You must keep your home’s humidity and moisture levels under control. You’ll see less mold if there is less moisture in your home.
