How to Tell Your Air Conditioner Has Mold

It’s essential to know the air conditioning in your building ties directly to its air quality. Discovering mold in ACs can be concerning for facility managers. When mold is left to spread, it can create serious health problems for your employees or clients. If you’ve found mold in your air conditioner, it’s essential to act quickly. Here are how an expert deciphers whether air conditioners have mold:

Know What Causes Mold in ACs

Moisture is the leading cause of mold growth. Molds thrive in wet environments, and air conditioners can often harbor moisture in the ductwork. AC in areas with higher humidity is also at increased risk for more moisture and mold development. If you know your AC has problems with moisture, it should be serviced and checked for any mold. Find ways to prevent condensation and keep your air filters clean to avoid too much moisture.

Visible Mold

You may be able to see the mold growth in your AC yourself. You can check areas with a flashlight if you suspect you may have mold. It’s a good habit to check the AC for mold whenever the filters are changed. Most common molds are reminiscent of mold you’d find in a basement. Mold in ACs will often be black and could wipe off easily. However, you’ll need professional cleaning to remove mold and prevent it from returning permanently. Mold can vary visually, so it’s best to have an HVAC contractor identify the problem.

Increase in Respiratory Issues

If you’ve received complaints about respiratory problems, your AC could be the culprit. Mold could be a slight irritant to some but can cause severe reactions in those with illnesses like asthma. It can also exacerbate allergy symptoms, making breathing uncomfortable and difficult.

While the AC is on, symptoms like irritated sinuses, eyes, or throats could all indicate you have a mold problem. It can also present like allergies, even those who don’t have allergy-like symptoms. Call a professional at the first sign. Mold can be incredibly harmful, especially over time, so it’s best to handle it immediately.

Distinct Odors

Mold has a pungent smell that’s noticeable even when the AC isn’t on. And the smell often gets more intense when the air conditioner is running. The smell could also worsen with humidity, and many describe it as having a “basement-like” smell. Luckily, the odor is unpleasant enough to get your attention. So this is another excellent time to be proactive and call a professional — when you notice the odor.

Your AC Is Set to a Low Temperature

Mold likes moisture and can spread like wildfire once you add warm temperatures. An air conditioner regularly set to a low temp could be at risk. The cool air in the vents combined with the warm air in the room is a recipe for condensation. If the moisture caused by this reaction doesn’t dry out, the result is often mold growth.

If you notice mold collecting around your vents, it’s a sign that the AC temperature is too low. ACs that may have leaks could also suffer from this problem, as they will let warm air in. A professional HVAC contractor can diagnose this problem and help you devise a solution.
