HVAC Tips for Homeowners in Thomaston & Middle Georgia
If you’ve noticed a musty smell coming from your air conditioning system, you’re not alone. Many homeowners in Georgia experience this issue when they first turn on their AC in the spring. While it may seem like a minor nuisance, a musty-smelling AC could be a sign of a deeper HVAC problem—and now is the perfect time to address it before the summer heat hits.
What Could Be the Culprit?
1. Clogged or Dirty Air Filter
When filters become clogged with dust and moisture, they can begin to grow mold and mildew—causing that unpleasant smell every time your AC kicks on.
2. Mold or Mildew Inside the System
If moisture gets trapped inside your ductwork or evaporator coils, it can quickly lead to mold growth. This is especially common in humid areas like Middle Georgia.
3. Clogged Condensate Drain Line
Your AC’s drain line removes moisture from the system. If it’s clogged, that water can back up and cause odors.
4. Dirty Evaporator Coils
Dust, moisture, and grime on your coils can create a musty or even sour smell. This buildup also reduces your system’s efficiency.
Quick Fixes You Can Try at Home
-
Replace your air filter – This should be done every 1-3 months to keep air clean and reduce odor.
-
Run a dehumidifier – Reducing indoor humidity can prevent mold from forming.
-
Check for standing water – If you see water near your indoor unit, it’s time to call in a pro.
