Installing air conditioning in a San Francisco home requires careful planning around the city's housing stock, SFDBI permit process, HOA restrictions, and California energy codes. We assess Victorians, Edwardians, Craftsman bungalows, lofts, and modern condos across the city.
Installing air conditioning in San Francisco is more complex than in most American cities — and getting it wrong is expensive. SF's varied microclimates mean that a home in the Mission District may have genuinely different cooling needs than a home three blocks away in Noe Valley. The city's Victorian and Edwardian housing stock typically lacks ductwork, making central AC difficult and expensive without significant renovation. HOA boards in multi-unit buildings often restrict exterior modifications. And the San Francisco Department of Building Inspection requires permits for most mechanical installations.
SF HVAC Repair navigates these challenges across San Francisco homes. Our installation process begins with a free in-home consultation and Manual J load calculation — the ACCA-standard method for determining the precise cooling capacity your home needs. Oversizing an AC system in an SF home is one of the costliest mistakes an installer can make: an oversized system short-cycles, never adequately dehumidifies (critical in SF's foggy climate), wears out faster, and costs more to operate. We size every system correctly, the first time.
No ductwork required. A 3-inch hole through the wall connects indoor air handlers to an outdoor condenser. Single-zone or multi-zone configurations. Brands: Mitsubishi, Daikin, Carrier.
Split-system central AC integrates with your existing furnace and ductwork. Brands: Carrier, American Standard, Daikin, Lennox, Rheem.
Perfect for a single bedroom, home office, or ADU that isn't connected to the main HVAC system. Can be installed in a single day. Ideal for SF in-law units and garden-level flats.
Provides both air conditioning and efficient heating in one system — ideal for SF's mild climate where both are needed seasonally.
Permits: The SFDBI requires a mechanical permit for central AC installations and most mini split installations involving electrical work. We handle all permitting — you never need to visit City Hall. Unpermitted HVAC work can affect your home sale, insurance coverage, and in some cases requires costly remediation.
HOA Restrictions: Many SF condo buildings and TIC buildings have HOA rules governing exterior modifications. We have experience navigating these restrictions and can help identify installation approaches that meet HOA requirements — including low-profile condensers, rooftop placement, and equipment concealment strategies.
Electrical Capacity: Many SF homes have older 100-amp or split-bus electrical panels that require upgrading before a new AC system can be added. We assess electrical capacity during the in-home estimate and coordinate the needed panel-work scope when required.
We install AC systems in all 28 SF neighborhoods — including Victorian-heavy districts, modern condo buildings, and multi-family properties.
