What San Francisco Homeowners Say About Brandt HVAC Co San Francisco
Reviews matter because a furnace that quits in a Richmond District January or an AC that dies during a Mission District heat wave isn’t something you want to gamble on. You want to know the tech who shows up knows San Francisco homes, respects your time, and stands behind the work. We earn what our customers say about us one visit at a time by doing three things without exception: putting a written price in your hand before any work starts, sending a tech you’ve already seen by name and photo, and backing every repair with a written guarantee and our 365-Day Done Right Promise.
Recent Reviews
“Our furnace started making a rattle that sounded like loose change in a dryer. The Brandt tech traced it to a blower wheel that had worked itself loose and was scraping the housing. He showed me the wear marks, gave me a written price to replace it, and had the heat back on that same afternoon. Quiet furnace now, and the guarantee was printed right on the invoice.”
Riya S., Outer Sunset
“Called at 11:30 on a Saturday night when our AC quit and the house was still 84 degrees. A live person actually answered, no phone tree, no callback queue. The tech arrived with a photo ID badge and fixed a failed capacitor on the spot. He walked me through the written guarantee before I paid a dollar. We slept cool by 1:30.”
Vivian L., Noe Valley
“I’d had two other companies quote me wildly different prices for a furnace repair. Brandt gave me one written price before the work began and there were zero surprises on the final invoice. The igniter had cracked, which the tech showed me on the old part before replacing it. This is what predictable pricing should look like.”
Emily P., Bernal Heights
“Scheduled AC maintenance before the summer rush and the tech spent a full hour and a half going through the condenser, the coils, the refrigerant levels. He found a small leak at a flare fitting and fixed it during the same visit. I got a written report of everything he checked. Ten months later the system is still holding pressure and cooling fine.”
Christine P., Potrero Hill
“Our old Goodman furnace had a rollout switch that kept tripping. The Brandt tech didn’t just reset it and leave. He checked the heat exchanger, found the baffles were dirty and airflow was restricted, cleaned everything, and gave me the written price before he started. No pressure tactics, no upselling. Furnace has run through two winters since with no issues.”
Riya S., Outer Sunset
“The AC started blowing warm air the week of Labor Day when San Francisco actually got hot. I called first thing and the tech was at our place in the Mission before noon. He diagnosed a refrigerant leak, found the bad Schrader valve, replaced it, and recharged the system. The price was in writing up front, the guarantee covered the repair for 365 days, and he told me if it leaked again he’d be back free of charge. It never did.”
