Most homeowners think of their HVAC system as just “climate control” — but it also plays a major role in indoor air quality (IAQ). The air you breathe passes through your HVAC system constantly, and if it’s not properly maintained, it can circulate allergens, pollutants, and moisture that lead to mold.

Here’s how your system can impact IAQ — and how to protect your home:

1. Dirty Filters = Dirty Air
   Filters capture dust, dander, pollen, and more. If they’re clogged, not only does efficiency drop — so does air purity.

2. Mold in Ductwork or Coils
   Moisture buildup inside air handlers or ducts can foster mold growth. That air then moves throughout your home.

3. Dry or Over-Humidified Air
   Poor HVAC balance can strip too much moisture (leading to dry skin and throat) or fail to remove enough, encouraging bacteria and mildew.

What You Can Do:

• Change filters regularly (HEPA if possible)

• Install a whole-home humidifier or dehumidifier

• Have your ductwork inspected and cleaned

• Schedule HVAC tune-ups twice a year

Breathing clean, filtered air is just as important as staying cool. A well-maintained HVAC system does both.
