Indoor Air Quality (IAQ) Solutions

Clean Air Where You Live and Work.

The air inside your home or building can be 2–5 times more polluted than the air outside. From mold spores, allergens and dust to volatile organic compounds (VOCs), poor indoor air quality contributes to headaches, fatigue, respiratory issues, and frequent illness—especially in airtight or energy-efficient buildings where pollutants can become trapped.

At Texas Retrofits by Pinnelli Builders, we help you take control of your air. Our Indoor Air Quality solutions are designed for homes, offices, and commercial buildings throughout the Austin area, where heat, humidity, and allergens pose serious challenges.

We assess your structure holistically to identify IAQ risks and recommend customized upgrades that may include:

• Whole-house air purification systems
• Medical-grade HEPA filtration
• UV germicidal light technology
• Balanced ventilation and fresh air intake
• Humidity control via whole-building dehumidifiers
• Sealed ductwork and attic ventilation improvements

Whether you’re trying to reduce asthma triggers at home or create a healthier environment for your employees and clients, our IAQ systems are engineered to deliver clean, comfortable air year-round.

Benefits of IAQ Upgrades:

• Reduce allergens, dust, and indoor pollutants
• Improve sleep, focus, and overall well-being
• Minimize HVAC strain by regulating humidity and airflow
• Lower the risk of mold and moisture-related damage
• Comply with healthy building standards for office or rental spaces
