Finding an HVAC company in San Francisco means working with homes that most other cities don’t have: 100-year-old Victorians with no ductwork, damp west-side microclimates that rust heating systems from the inside, and tight lots where outdoor condenser placement takes real planning. Brandt HVAC handles all of it, with written pricing before any work starts and a technician sent to you by name and photo before we ring the bell. If your heat won’t hold or your AC has given up, call (559) 245-8807 and a live person answers.
Why San Francisco Homes Are Different
San Francisco’s housing stock runs old, wood-framed, and tightly packed. Pre-1950s Victorians and Edwardians dominate whole swaths of the city, and many were built without central air or even forced-air heat. Gravity furnaces still lurk in Sunset District basements, installed decades before anyone worried about rusted heat exchangers or sealed combustion. Add the marine layer that rolls through the Richmond and Sunset most summer days, and you get a specific set of problems: dampness creeping into ducts, moisture corroding furnace interiors, and heating demand that spikes hard on foggy July nights despite the mild daytime temperatures.
Space matters here too. A condenser squeezed between two buildings in the Mission behaves differently than one sitting in a wide Daly City lot. Retrofitting a Noe Valley flat or a Marina District Edwardian often means ductless mini-splits, high-efficiency boilers, or careful zoning work because running new ductwork just isn’t possible. Permits add another layer, especially in historic districts where exterior changes face review. None of this is generic HVAC work, and we treat every San Francisco job that way.
Styles & brands we work with
Our Main San Francisco Services
The three calls we get most from San Francisco homeowners are AC repair, furnace repair, and AC maintenance. Each one has its own page with pricing and detail, so you can see exactly what to expect before you pick up the phone.
AC Repair in San Francisco
San Francisco doesn’t get the heat that Sacramento or Walnut Creek does, but when the fog clears and the sun sits over the bay, a dead AC in a top-floor flat becomes a real problem fast. Older homes often run window units or small central systems, and the salt air plus damp means coils corrode and refrigerant lines leak sooner than they would inland. We diagnose the problem, show you the written price, and fix it. Most AC repairs in San Francisco run $175 – $765, parts and labor included. AC Repair in San Francisco has the full breakdown by job type.
Furnace Repair in San Francisco
Furnace repair is the bigger business in San Francisco, because heating here isn’t optional. The marine layer keeps nights cold year-round, and homes in the Sunset, Richmond, and Parkside run their furnaces even in July. Those systems work hard in damp basements and crawlspaces, which is why we see so many rusted heat exchangers, failed igniters, and airflow problems. We tell you what’s wrong, what it costs to fix, and what the guarantee covers before we touch a tool. Typical furnace repairs run $175 – $825. Furnace Repair in San Francisco lists common repairs and their price ranges.
AC Maintenance in San Francisco
AC maintenance here isn’t just about cooling. In San Francisco, it’s about keeping a system that sits idle eight months of the year from corroding, leaking, or locking up when you finally need it. The salty, damp air is hard on coils and electrical connections, and a tune-up before the warm season catches problems early. We inspect, clean, test, and report exactly what we found. A San Francisco tune-up runs $95 – $235. AC Maintenance in San Francisco covers what’s included and why it matters here.

AfterPricing for HVAC Company in San Francisco, CA
Below are the price ranges we see most often in San Francisco. Every job gets a written price before any work begins, so what you see here is what shapes your quote.
| Service | Typical range in San Francisco |
|---|---|
| AC repair | $175 – $765 |
| Furnace repair | $175 – $825 |
| AC installation (full system) | $4,130 – $8,850 |

What pushes a San Francisco repair toward the high end of a range is usually access. Tight crawlspaces, rooftop condensers on mid-century apartment buildings, or equipment jammed into a closet that wasn’t built for it all add labor time. What doesn’t change is how we price: written, specific, and agreed to before work starts.

FAQs About HVAC Company in San Francisco
For a furnace that won’t heat or an AC that won’t cool, we schedule same-day visits in most of San Francisco, Monday through Sunday. Heating failures in damp weather get priority because a cold, wet house is a health risk, not just a comfort issue. Call (559) 245-8807 and a live person will give you a straight arrival window.
Some HVAC work in San Francisco requires a permit, especially furnace replacements, new installations, or any job that modifies ductwork in a multi-unit building. Historic districts can add exterior placement review. We handle the paperwork as part of the job and tell you before any work starts whether a permit applies to your specific situation.
Yes. San Francisco basements, rooftops, and tight side yards are a big reason we send technicians who know the city’s building stock. We also confirm access details when you book, so the tech arrives with the right ladder, the right parts, and the right plan. You’ll get their name and photo before they arrive, and they’ll show ID at the door.
