Air Quality Heating & Air Conditioning

Air Quality Heating & Air Conditioning has kept Bay Area homes comfortable since 1999, building a track record reflected in a 4.8-star rating drawn from 76 client reviews. This San Jose-based contractor specializes in residential heating and cooling systems, with particular depth in San Jose, Sunnyvale, Saratoga, Palo Alto, Mountain View, Cupertino, and surrounding communities across Santa Clara and San Mateo Counties. Their team holds proper licensing for installation and repair work in California's rigorous regulatory environment, and the company has maintained continuous operation through multiple economic cycles in the South Bay.

What distinguishes this contractor is a strategic partnership with Carrier, one of North America's most established HVAC equipment manufacturers, combined with an emphasis on HVAC zoning technology. Rather than treating an entire home as a single thermal zone, their zoning systems allow homeowners to heat or cool independent areas, say, a home office versus a living room, each to different temperatures. This approach reduces energy expenditure while addressing the common complaint that one room stays too warm while another remains cold. The company also assists clients with rebate paperwork and permit coordination, navigating the administrative side of equipment upgrades that many homeowners find daunting.

Technician Miguel demonstrated the kind of rapid diagnosis that earns five-star reviews when he arrived at a residence to troubleshoot a furnace that would not ignite. After methodically checking several potential causes, he traced the problem to a burnt-out switch, a failure caused by earlier faulty electrical work by another contractor. Miguel and his supervisor Robert installed a modern fused switch, completing the repair in under an hour and avoiding a second appointment. Another reviewer, Lubomir Bourdev, noted that Matt Farber's crew handled a complex furnace and heat pump replacement in just a few hours while assisting with utility rebates and even investigating a phantom power issue that fell outside their scope.
