How do you prevent mold in air ducts

One of the most common complaints about HVAC systems is mold build up. Molds can cause a lot of issues not only for your heating and cooling system, but may also pose a health hazard for your family by aggravating respiratory conditions such as asthma and allergies.

Molds tend to reproduce by means of tiny spores that are invisible to the eye. They typically grow on wet or moist surfaces. They need moisture to reproduce, and can easily end up damaging parts of your home without you even noticing.

In the following article, we’ll help you keep the HVAC ducts at your property free of dangerous molds by providing you with some time-tested guidelines. Read on to learn more.

How do you prevent mold in air ducts?

To prevent molds and mildew from building up in your air ducts and HVAC system, make sure to do some or all of these things:

Check drain pans

If drain pans are not cleared out from time to time, they may accumulate excess water, which will increase moisture levels in your air ducts and lead to mold and mildew growth. Making drain pan checks a part of your winter HVAC maintenance is highly recommended.

Replace air filters regularly

Air filters are inefficient at trapping mold spores and other contaminants if they become wet and clogged, so make sure to replace them once a month or as they get grimy. Investing in high-quality filters may be a great idea if you suffer from allergies or are otherwise sensitive to airborne pollutants.

Improve the ventilation system

Investing in a high-quality ventilation system that reduces the risk of mold, mildew, and other problems is a great way to ensure great indoor air quality at your home, maintain healthy humidity levels throughout winter, and also boost the value of your property.

Disinfect the HVAC system & apply inhibitors

Treat your air ducts with disinfectant that is intended for HVAC use. After this, apply a HVAC-approved mold inhibitor that prevents mold and mildew growth. Make sure to follow the instructions on the label to ensure optimal results.

Keep the air ducts dry

Some parts of the air duct system are extra-prone to moisture buildup, which increases the risk of mold. Have them checked and cleaned by the professionals, and repair or replace damaged parts that are showing signs of getting moldy or are at risk of a pest infestation.

Fix water leaks immediately

If your HVAC system and air ducts are situated where there are leaks, they’re more likely to become infested with mold and mildew. Fix these leaks immediately to control the spread of mold and prevent further damage to your air ducts.
