Indoor air quality has become a growing concern for homeowners throughout San Jose and the Bay Area. Seasonal wildfire smoke, pollen, dust, and everyday household pollutants can accumulate inside homes and circulate through HVAC systems. For families with allergies, asthma, or respiratory sensitivities, poor air quality can affect daily comfort and health.
