Indoor Air Quality Solutions in Lodi, WI

Breathe Easier With Better Indoor Air Quality

You can’t always see air quality problems, but you can feel them. Whether it’s allergies, excess dust or persistent odors, poor indoor air quality (IAQ) affects your comfort, health and even your HVAC system’s performance.

At Hillestad Heating and Cooling Systems, we help you breathe easier with expert IAQ solutions that make your home safer, fresher and healthier year-round.

Why Indoor Air Quality Matters

The EPA reports that indoor air can be 2–5 times more polluted than outdoor air. That’s because your home traps airborne particles, moisture and contaminants, especially when it’s sealed tight for energy efficiency.

Common IAQ concerns include:

• Dust, pet dander and pollen

• Mold and mildew from excess humidity

• Smoke, cooking and chemical fumes (VOCs)

• Bacteria, viruses and airborne pathogens

• Poor ventilation and stale air

These pollutants don’t just irritate allergies, they can worsen asthma, lower sleep quality and increase the risk of illness.
