The San Francisco HVAC market is characterized by a high demand for reliable heating systems due to the city's cool, foggy summers and chilly, damp winters. There is less emphasis on high-capacity AC than in other parts of California, but a growing demand for heat pumps and dual-fuel systems that provide both efficient heating and cooling. The prevalence of older housing stock creates a need for contractors skilled in retrofitting systems into tight spaces without compromising historic integrity.

Get answers to common questions about hvac services in San Francisco, California.
For a full system replacement (furnace and air conditioner) in a standard San Francisco single-family home, homeowners can expect a range of $10,000 to $20,000+. The high end accounts for the complexities of older homes, potential asbestos or lead abatement, and the need for high-efficiency, properly sized systems for our mild but variable climate. Always get multiple, detailed quotes that include all permits required by the San Francisco Department of Building Inspection.
The optimal times are during our mild shoulder seasons—late spring (April-May) or early fall (September-October). Scheduling during these periods avoids the summer rush for AC service during our rare heat waves and the winter demand for furnace repairs. This ensures better availability, often shorter wait times, and allows you to address any issues before you critically need the system.
Absolutely. Systems must be correctly sized for our cool, damp summers and chilly, foggy winters; oversized AC units are a common mistake. For the many pre-1978 homes, reputable contractors must follow EPA RRP rules for lead-safe practices during ductwork modifications. Furthermore, proper ventilation and humidity control are crucial to prevent mold in our damp climate, making features like variable-speed fans and whole-house dehumidifiers valuable.
Always verify the contractor holds a valid California C-20 (Warm-Air Heating, Ventilating and Air-Conditioning) license and proper insurance. Choose a company experienced with San Francisco's permit process and older home architectures (like balloon framing). Look for strong local reviews mentioning clear communication, as navigating small access points, historic preservation rules, and tenant notifications are common challenges here.
Ductless mini-split heat pumps are an excellent and increasingly popular solution. They provide highly efficient zoned heating and cooling, which is ideal for San Francisco's microclimates and multi-story homes. They avoid the major construction of adding ducts and qualify for rebates from programs like BayREN. For whole-house solutions, high-velocity mini-duct systems are another option that can be retrofitted with less intrusion.
