Most people spend 80% or more of their time indoors. The air inside your home can contain dust, pollen, pet dander, mold spores, bacteria, and volatile organic compounds — often at concentrations higher than outdoor air. These pollutants circulate through your HVAC system and affect everyone in the home, especially those with allergies, asthma, or respiratory conditions.

Central Texas adds specific challenges. Georgetown’s limestone dust, Abilene’s wind-driven dirt, and the pollen seasons across the region all contribute to indoor air quality problems. New construction homes can also trap volatile compounds from building materials, paint, and adhesives.
