Mold is a common allergen and can cause flu-like reactions. In those with preexisting respiratory issues, it can cause more serious breathing problems. Spores can settle in your HVAC system and, once the blower is activated, circulate throughout your home. The guide below looks at warning signs that there are spores in your air so you can enlist the help of an HVAC contractor.

Understanding Mold in HVAC Systems

How to Detect It

Look for white, green, gray, or brown spots with a cotton-like texture that may be growing around your ductwork, vents, on the evaporator coils located on the back of your HVAC unit, and in the drip pan below your HVAC unit. 

You may also smell the mold in your ductwork. It produces a musty, unpleasant odor similar to mildew. Turn the system off, wait 20 minutes, and turn it on again to see if the smell is still there. Contact an HVAC contractor to take a closer look if so.

Sometimes, the only sign of mold is the allergic reactions family members are experiencing. Long-term exposure can lead to coughing, sneezing, runny nose, headaches, and skin rashes. Reactions can be more severe for infants, those with existing respiratory conditions, and seniors with weakened immune systems.

How to Treat & Prevent It

Mold thrives in moisture, which is why drip pans that catch condensation are common locations to find spores. Tilt the pan up on one end so that water runs off of it rather than pooling. Check that drain lines on your unit aren’t leaking. If they are, call an HVAC contractor to repair the issue.

You can manage existing mold by installing HEPA air filters in your system. These capture small particles and contaminants like mold spores. You can also schedule duct cleaning with an HVAC contractor. These professionals will use a snake vacuum system to remove debris from the ductwork.
