AfterHVAC Company in San Francisco, CA
Dalton Heating & Air is the HVAC company San Francisco homeowners call when the fog rolls in and the heat stops working, or when a Victorian’s radiators finally give out and a heat pump starts looking like the right move. Heating and cooling work in San Francisco is shaped by three things: housing stock that runs from 1890s Edwardians to 1960s Sunset boxes, a marine layer that cools the west side while the Mission bakes, and streets steep enough to make a service van work for its brakes. We answer the phone live, 24/7, at (361) 306-9515. The price is in writing before any work starts.
Why San Francisco Homes Are Different
An HVAC call in San Francisco is rarely a simple swap. Homes in the Richmond and Sunset are often single-pane-windowed and built without central heat, which means system sizing has to account for fog-cooled summers, not just winter nights in the high 30s. A furnace in an Inner Sunset garage closet deals with salt air off Ocean Beach eating at the heat exchanger. A condenser on a Noe Valley deck faces a different microclimate than one on a flat Bernal Heights roof. Terrain changes everything: some Mission District streets require a crane for rooftop work, and a Diamond Heights split-level can push a furnace into an attic serviced by a ladder, not a hallway.
Then there is the permitting reality. San Francisco’s Department of Building Inspection has its own mechanical permit process, and many jobs on multi-unit buildings need HOA sign-off before a crew touches the equipment. We work with both. Marco Benitez, our lead in the San Francisco Bay Area, handles the scheduling and the paperwork so the job does not stall on a form.
Our Main San Francisco Services
Most San Francisco homeowners reach out for one of three reasons: the AC is not cooling, the furnace is not firing, or the time has come to replace an aging system with a heat pump sized for the city’s mild-but-persistent climate. Each of these has its own San Francisco page with pricing and specifics.
AC Repair in San Francisco
San Francisco does not have the inland heat, but it does have microclimates that make a working AC matter on a September afternoon in the Mission or Potrero Hill. Common calls: a condenser tripping its breaker, a blower that runs but pushes warm air, or a refrigerant charge that has leaked down over the winter. Our AC Repair in San Francisco page covers what the job costs, what we check first, and how fast we can get a technician to you.
Heat Pump Installation in San Francisco
More San Francisco homeowners are replacing furnaces with heat pumps, particularly in older homes where there was never ductwork. A ducted or ductless heat pump suits the city’s moderate climate and handles both heating and cooling from one system. Bay Area utility rebates can offset part of the cost, and the installation involves an electrical service assessment as much as the mechanical work. We stock equipment from carriers including Rheem and Daikin. See Heat Pump Installation in San Francisco for pricing and what the install day looks like.
Furnace Repair in San Francisco
San Francisco’s housing stock means we see a lot of older forced-air furnaces and gravity heaters, some of them original to 1920s homes in the Richmond and Sunset. A furnace that will not fire in a January damp spell is a pressing problem: the temperature is not the only issue, mold and moisture creep into cold, unheated rooms quickly. We service all major brands, including Bryant and York, and stock common ignitors, flame sensors, and pressure switches locally. Full details: Furnace Repair in San Francisco.

Brands We Service in San Francisco
Our technicians are factory-trained on the equipment San Francisco homes actually have. We service Rheem, York, Daikin, and Bryant regularly, and we keep the high-failure parts for those brands on the vans rather than waiting on a distributor. That means most repairs finish in one visit. See our brands for the full list.
Pricing for HVAC Company in San Francisco, CA

What pushes a San Francisco repair toward the top of that range is access: a furnace in a tight basement in the Marina or a rooftop unit needing a ladder and safety tie-offs on a Portola hillside takes more time and more care. Whatever the number, you get it in writing before we turn a wrench. If the repair fails within a year, we return at no charge.
