Mold in HVAC Systems: Detection & Prevention

When we think of mold and the places it can appear, we usually think of basements, bathrooms, roofs, etc. But we never think of those unassuming spots such as our ventilation and HVAC systems.

However, they are some of the most common and convenient places for mold to grow, with a heightened effect of spreading airborne spores around your home.

That’s why it’s crucial that you spot it in time and treat it appropriately before it wreaks havoc on our house and health.

To help you figure out what you’re looking for, here are the main signs of mold in HVAC systems and what you can do to prevent it from growing in the future.

Let’s jump into it!

Signs of Mold in HVAC Systems

There are a couple of clear signs you probably have mold in your HVAC system. Don’t view these as absolute guarantees, but consider them as strong indications that it’s time for an inspection.

1. A Musty Smell

The most obvious sign of mold in your HVAC system is an earthy or musty smell that occurs every time you turn your AC on. This odor is due to microbial volatile organic compounds which are distributed through the air when the system is turned on.

2. Allergic Reactions

If you have a stuffy nose, itchy throat, sensitive eyes, sneezing, or coughing frequently while in the rooms where the AC is on, it might be worth giving it a check.

Many people take these symptoms as normal and expected signs of AC exposure, but they’re not. While a dry throat and nose can be a product of the dry air the AC emits, anything more than that is not within the normal range. It’s an alarming sign for further inspection and potential mold remediation.

3. Increased Energy Bills

Mold can negatively decrease the effectiveness of your AC unit, causing it to work more to make up for its shortcomings. So take a look at your electricity bill and see if it has been higher than usual.

The culprit might be the mold inside your HVAC system.

4. Bad HVAC Performance

As we’ve mentioned above, mold can significantly affect your AC. That’s why you may notice that it doesn’t cool your rooms the way it used to. If that’s the case, give it a check for mold – maybe it’s time for mold removal.

How To Prevent Mold In Your HVAC System?

The main thing that prevents mold in AC systems is regular maintenance. Before every summer season, make sure you get your HVAC system professionally checked and serviced to ensure that everything is working properly and cleanly.

If you are looking for what you can do yourself in this department, here are the crucial steps to help you stop mold from growing in your AC:

1. Replace your HVAC filters regularly

2. Insulate air ducts

3. Check and clean your condensate/drip pans

4. Fix leaks promptly
