GB Heating & Cooling - San Francisco's Experienced HVAC Repair

We handle installation and replacement for a wide range of systems, including gas furnaces, ductless mini-splits, rooftop units, and radiant heating systems. Since 2002, we've worked with all major brands and provide personalized design to match your home's layout and efficiency needs while following San Francisco building codes.

Many older San Francisco homes have uneven temperature zones due to layout or outdated ductwork. We assess your entire system, recommend solutions like zoning controls or duct adjustments, and ensure proper airflow balance. Our maintenance services include checking for these issues to improve comfort and efficiency.

Our maintenance covers system cleaning, component inspections, performance checks, and addressing common issues like clogged condensate drains. We also educate homeowners on simple upkeep and efficiency tips. Regular maintenance helps prevent breakdowns and extends system life, which is especially valuable in San Francisco's variable climate.
