If you’ve been noticing a musty smell when your AC kicks on, or you’ve peeked inside your air handler and seen something dark on the coils, it’s normal to feel a little concerned. Black mold on AC coils is something we come across often here in Tampa Bay, and while it’s not something to panic about, it is something you want to address sooner rather than later.
Between the heat, humidity, and how often our systems run, your air conditioner naturally becomes a perfect environment for moisture. When coils stay damp and airflow isn’t great, mold can start to grow, usually slowly at first, then more aggressively if it’s left alone.
Let’s talk about what causes it, what to watch for, and how we help keep your system clean and safe!
Why Mold Forms on AC Coils
At the end of the day, mold needs two things to grow: moisture and warmth.
Unfortunately, local homes offer plenty of both. Your AC coils pull humidity out of the air, so they’re often covered in condensation. If the system isn’t draining properly or the airflow is restricted, that moisture can stick around longer than it should.
Dust buildup can also feed mold, giving it a place to grow. This is another reason why routine maintenance makes such a big difference.
Signs You Might Have Mold
Most homeowners don’t notice mold visually; they smell it first. Common signs include:
- A musty or “dirty sock” odor when the AC turns on
- Increased allergy-like symptoms
- Visible dark or fuzzy spots on or near the coils
- More dust inside the home than usual
