Indoor air pollution can come from many different sources inside and outside the home. Dust, pet dander, pollen, and mold spores often accumulate in HVAC systems and ductwork over time. Household products such as cleaning chemicals, paints, and building materials can also release volatile organic compounds (VOCs) that affect indoor air quality. In Austin and San Antonio homes, high humidity and long cooling seasons can contribute to mold growth and airborne particles circulating through the system. Poor ventilation or aging HVAC equipment can further trap contaminants indoors. Radiant Plumbing & Air Conditioning helps homeowners address these issues by evaluating how air moves through the home and recommending solutions designed to improve ventilation, filtration, and overall indoor air quality.
