Our Furnace Repair crews know Berkeley’s housing stock the way only a local team can. We see 1920s gravity furnaces in the flatlands, heat pumps retrofitted into hillside mid-century homes, and the occasional floor furnace that hasn’t been opened since Eisenhower was president. This page is for Berkeley homeowners who want to understand what the repair involves, what it costs, and exactly who’s coming to do it.
Why Brandt HVAC Co San Francisco Is Berkeley’s Preferred Furnace Repair Company
Berkeley homeowners call us because we do something most HVAC companies skip entirely: we tell you who’s coming before they arrive. Every Brandt HVAC technician carries a photo ID badge and is background-checked under the Threshold Verified standard. You’ll receive the name and photo of your technician before the appointment. If someone shows up who you weren’t told to expect, that visit is on us and we make it right. That matters a lot to a parent home alone with young kids, or an older Berkeley resident who’s learned to be cautious about opening the door.
We also don’t play pricing games. Every job starts with a written price you see and sign before work begins. No exceptions. Every repair includes a written guarantee. And under our 365-Day Done Right Promise, if the repair fails within the year, we return at no charge. That’s a full year of certainty, in writing.
Founded in 2003 as part of the Threshold Group family, Brandt HVAC carries the name from an old word for a firebrand. That fits. Keeping Berkeley homes warm in January fog is exactly the kind of work a firebrand name belongs on. Devin Marlowe, our owner, holds the team to one standard: every homeowner in Berkeley gets a straight answer, a fair written price, and a technician they can verify before the door opens.
Scheduling for Berkeley repairs is coordinated from our San Francisco Bay Area office, and our crews serve Berkeley neighborhoods directly, from the flatlands to the hills.
Styles & brands we work with
Heat Pump Repair in Berkeley
Heat pump repair in Berkeley usually means diagnosing a reversing valve that’s stuck in cooling mode, or an outdoor coil that has corroded in the marine air of West Berkeley. Homeowners on the hillside, where temperatures drop a few degrees lower than the flatlands, notice heat pump failures first in January and February, when the system is asked to heat for the first real stretch in months. Typical heat pump repair in Berkeley runs $150 – $650, including the part and the labor.
Common heat pump failures we find in Berkeley
The most common issue we find in Berkeley is a reversing valve stuck in cooling mode, which leaves the house blowing cold air when the thermostat calls for heat. Salt air near the bay also eats outdoor coil fins faster than you’d expect. We clean and test the entire system before quoting, so you aren’t paying for a guess.
When a written quote matters most
A heat pump has more moving parts than a furnace, and a misdiagnosis can turn into a second visit and a second charge. That’s exactly why we give you a written price before the repair starts. If a second fix is needed within 365 days, the return visit is free.
Heating Repair in Berkeley
Heating repair in Berkeley isn’t about rescuing a house from a blizzard. The city’s Mediterranean climate means short, sharp bursts of heating need in December and January, and a furnace that sits idle through Berkeley’s foggy summers. The failures we see are less about extreme cold and more about what happens when a 1920s system sits damp and dormant for most of the year. Expect heating repair in Berkeley to run $150 – $700 for a typical call.
The damp-air factor
Berkeley’s marine layer does something mean to dormant furnaces: it lets moisture into heat exchangers and electrical connections. When a furnace in Elmwood or North Berkeley kick-starts for the first cold night, the water that sat on a gas valve all summer becomes a short or a stuck valve. We test for exactly that before recommending a part replacement.
Older panels, older wiring
Many Berkeley homes from the 1920s still run on 100-amp electrical panels. An aging blower motor pulling just a few extra amps can trip a breaker on the first heavy heat cycle. Our techs check the panel load and motor draw together, because in an old Berkeley bungalow, the furnace and the electrical system age together.
Trusted Brands We Service in Berkeley
We service all major residential HVAC brands, including Carrier, Trane, Lennox, Goodman, Rheem, York, Daikin, Bryant, and American Standard. For Berkeley’s older housing stock, we keep common parts stocked locally so a York heat pump in the Berkeley Hills or a Bryant furnace in South Berkeley doesn’t sit cold while a part ships from a warehouse. Fast turnaround matters when the fog rolls in and the house cools fast.

AfterCommon Furnace Repair Problems We See in Berkeley Homes
- Cracked heat exchangers on original gravity furnaces. The salt-heavy air in West Berkeley and the fog that rolls through the flatlands accelerates corrosion inside 1920s gravity furnaces. A cracked heat exchanger is a safety issue, and in many cases in Berkeley, the fix is replacement, not a patch.
- Blower motors tripping breakers on 100-amp panels. 1920s bungalows in North Berkeley and Elmwood often still have their original electrical panels. An undersized or aging blower motor draws extra amps and trips the breaker right when the heat is needed most.
- Clogged condensate lines on rarely-used furnaces. It sounds backwards, but Berkeley’s mild winters mean furnaces sit idle for long stretches. Debris and sediment settle in condensate and drain lines, then clog on the first real heating cycle. We flush and clear these as part of a standard repair call.
- Furnace smell of burning dust on first startup. Dust settles on the heat exchanger while the furnace sits off through Berkeley’s long mild season. The first ignition burns it off and produces that smell. We inspect to make sure it’s just dust and not a cracked exchanger or overheating blower motor.

FAQs About Furnace Repair in Berkeley
Yes, replacing a gravity furnace in Berkeley generally requires a mechanical permit, and the city’s energy-efficiency ordinance adds additional requirements for pre-war homes. Berkeley pushes electrification hard, so the permit process often includes a review of whether the replacement meets current efficiency standards. We handle the permit paperwork for you and the inspection coordination. Call (559) 245-8807 and we’ll walk you through what your specific home will require.
Yes. A mini split that won’t heat in Berkeley’s fog often has a refrigerant charge issue or a fouled outdoor coil, not a failed compressor. Our techs test the system under load and give you a written price for the exact repair before starting. We see this frequently in Berkeley Hills homes where mini splits are the sole heat source for an addition. Call (559) 245-8807 for a free estimate.
That smell is almost always dust that settled on the heat exchanger during the months the furnace sat idle, burning off when the unit first fires. In Berkeley’s mild, foggy climate, furnaces sit dormant for so long that this happens every single year. We inspect the heat exchanger to confirm it’s just dust and not something more serious, and the check is part of any repair visit. Call (559) 245-8807 if the smell persists or becomes acrid.
Yes, but it won’t always mean traditional forced air. For a Craftsman bungalow without ductwork, we often recommend either a ductless mini split system or a high-efficiency furnace paired with a well-designed short duct run, depending on the home’s layout and the city’s energy-efficiency permit requirements. We recently repaired a 1930s gravity furnace in a North Berkeley Craftsman on Walnut Street. The heat exchanger had cracked from decades of marine-layer moisture, and the original asbestos-wrapped ducts were too degraded to reuse. Our techs removed the old unit, installed a new high-efficiency furnace sized by a Manual J load calculation, and added a mini split for the upstairs bedroom that never had heat, all within the city’s energy-efficiency permit requirements for pre-war homes. That’s the kind of smart, code-aware answer Berkeley homes demand. Call (559) 245-8807 and we’ll assess your specific bungalow.
You’ll likely hear a humming sound from the furnace but the blower won’t start, or the blower starts slowly and runs warm. In Berkeley’s older homes, capacitors degrade faster when furnaces sit unused for long, damp stretches. A failing capacitor is a cheap fix compared to a blower motor, so checking it early saves money. Call (559) 245-8807 and we’ll test it as part of the diagnostic.
