Mold in an air conditioner is one of the more unpleasant problems an AC owner can face, and it’s not just a smell issue. Because your system blows air into every room, mold spores get carried right along with it, which can affect your family’s health. Here’s how to spot it and what to do.
Signs of Mold in Your AC
- A persistent musty or earthy smell when the AC runs
- Visible black or green spots on vents, the coil, or in the unit
- Worsening allergy or respiratory symptoms when the AC is on
- Excess moisture around the indoor unit
Why Mold Grows in ACs
Air conditioners pull moisture out of the air, which means the inside of the system stays damp, exactly the conditions mold needs. Add trapped dust as a food source and a clogged drain pan holding standing water, and you’ve got a mold-friendly environment.
The Health Risk
Mold spores blown through your vents can trigger allergies, asthma flare-ups, and respiratory irritation. That’s why mold in an AC isn’t something to put off.
Cleaning It Safely
Light surface mold on accessible parts can sometimes be cleaned with a diluted vinegar or bleach solution, dried fully before reassembly. But the coils, drain pan, and ductwork are hard to reach, and scrubbing the wrong way can damage the system. For anything beyond the surface, a professional cleaning is the safe call.
