Straight answers to the questions San Francisco homeowners ask us most about heating and cooling. If you don't see your question here, call (559) 245-8807 and our team will walk you through it.
Pricing & Cost FAQs
Most HVAC repairs in San Francisco run between $180 and $650 depending on the part and the system. A failed capacitor or contactor sits at the low end, while a blower motor or control board replacement lands higher. San Francisco's older housing stock means we frequently see systems from the 1990s and early 2000s, and those sometimes need two or three smaller repairs in a single visit. Before any work starts, you'll get a written price from us. That's how Devin Marlowe runs this branch, and it's part of the Threshold Standard we follow on every job. Call (559) 245-8807 for an exact quote on your system.
A full heating and cooling system replacement in San Francisco typically costs between $9,000 and $18,000 depending on equipment efficiency, home size, and ductwork condition. Homes in neighborhoods like the Sunset and Richmond District often have tight crawl spaces and older duct runs, which can add labor time. San Francisco's mild climate means many homeowners do well with a mid-efficiency heat pump rather than a top-tier unit built for extreme cold. We'll give you a written, fixed price before ordering any equipment. Call (559) 245-8807 and we'll put together a quote specific to your home.
An HVAC tune-up or maintenance visit in San Francisco generally costs between $120 and $250, with the lower end for a single system check and the higher end for a more involved cleaning and calibration. Fog and salt air near Ocean Beach and the Outer Sunset can accelerate corrosion on outdoor condenser coils, so we recommend an annual cleaning if you're within a mile of the coast. Our maintenance visits include a written report of what we found and what we did. Technicians are not paid on what they sell, so you won't get a sales pitch disguised as a checkup. Call (559) 245-8807 to schedule yours.
Yes, San Francisco requires a building permit for most HVAC equipment replacements, including furnaces, heat pumps, and air conditioners. The city's Department of Building Inspection handles these permits, and the process includes an inspection after installation. Some replacements that match the existing system's capacity can be done under a simpler over-the-counter permit, but anything involving new ductwork or moving the equipment typically needs a full review. We handle the permit paperwork as part of the job and schedule the inspection for you. If you're unsure whether your project needs one, call (559) 245-8807 and we'll tell you straight.
San Francisco HVAC work costs more because labor rates, permit fees, and real estate costs for contractors are all higher than most of the country. Parking in neighborhoods like Noe Valley or North Beach is tight, which adds time to every job. Older homes often have non-standard framing that slows installation. The city's energy codes also require specific equipment efficiency ratings, so you may need a more expensive unit than you would in another state. We keep our pricing transparent so you know what you're paying for. A written estimate from us means no surprise charges after the work is done.
Service & Process FAQs
During a service call, a technician diagnoses the problem, explains what they found in plain language, and gives you a written price before any work starts. They'll check the thermostat, electrical connections, refrigerant levels if applicable, airflow, and the condition of major components. They should also check the filter and tell you if it needs changing. At the end of the visit, you'll get a clear summary of what was done and what, if anything, needs follow-up. That's the standard we hold every tech to under Threshold Verified. If you have questions after the tech leaves, call (559) 245-8807 and we'll answer them.
You'll know before the visit. The Threshold Standard requires that we send you the technician's name and photo before they arrive. When they show up, they'll be wearing a clean, marked uniform and carrying a photo ID badge that matches the person you were told to expect. No surprises. That's the whole point of the promise behind Brandt HVAC: you open the door to someone you recognize. If anyone shows up who you weren't told to expect, that visit is on us and we make it right. Devin Marlowe's team in San Francisco operates by that same rule, every time.
Yes, always. Every job gets a written price before any work starts. That's a non-negotiable part of how we operate. You'll see the cost broken down clearly and you'll approve it before the technician picks up a tool. If something changes once work begins, we stop and talk to you first. You're never obligated to proceed just because we're on site. This is the same standard across every Brandt HVAC location, and it's how we've earned trust with homeowners in neighborhoods from Bernal Heights to the Marina. Call (559) 245-8807 if you'd like a quote for your system.
Most common repairs take 1 to 3 hours once the technician is on site and the part is in hand. Replacing a capacitor, contactor, or igniter is usually under an hour. A blower motor or circuit board swap might take two hours. If the part isn't on the truck, which happens more often with older or less common systems, we'll order it and return once it arrives. You'll know the timeline before we start the work. For anything urgent, call (559) 245-8807 and we'll get you on the schedule as soon as our hours allow.
A full system replacement usually takes 1 to 2 days, depending on the size of the home, the condition of the ductwork, and whether we're replacing just the equipment or reworking the ducts too. A straightforward furnace swap in a single-family home can often be done in a day. Adding a heat pump, new lineset, and air handler to a multi-story house like those in Pacific Heights might stretch into the second day. We'll give you a set install date and a clear schedule before the equipment is ordered. No vague "sometime next week" promises. Call (559) 245-8807 to get a timeline for your project.
Brands & Parts FAQs
We install and service major brands including York, Bryant, and American Standard, among others. We also work on Daikin systems, which have become popular in San Francisco for their efficiency in mild coastal climates. The right brand for your home depends on your budget, your home's layout, and how long you plan to stay there. We'll give you honest guidance on which units hold up best near the fog belt versus which make more sense for inland areas like the Mission or Potrero Hill. Call (559) 245-8807 and we'll walk you through the options for your home.
For San Francisco's mild, fog-heavy climate, a mid-efficiency heat pump from a brand like Daikin or Bryant often makes the most sense. You don't need the extreme cold-weather performance that a homeowner in Truckee would. What you do need is solid humidity control and a unit that handles damp, salty air near the coast without corroding early. American Standard and York also make strong mid-tier options that balance price and longevity. The best brand is the one matched to your home's size and your budget, not the one with the biggest marketing budget. We can help you choose without the sales pressure.
Not always, but it's often the smarter financial move if both units are past 12 to 15 years old. A new high-efficiency condenser paired with an aging furnace can create a mismatch that reduces efficiency and strains both systems. Replacing both at once also saves you a second round of labor and permit fees down the road. That said, if your furnace is in good shape and your AC failed early, we'll tell you that too. Our job is to give you the honest answer, not to upsell you. Call (559) 245-8807 and we'll assess what your system actually needs.
We don't install customer-supplied parts. The reason is simple: we can't stand behind a part we didn't source, and you deserve a guarantee on the work you pay for. Parts bought online often arrive damaged, counterfeit, or incompatible with your system, and that turns into a headache for everyone. When we supply the part, it's covered under our warranty and the manufacturer's warranty. That's part of the accountability the Threshold Standard demands. If you're trying to save money, call (559) 245-8807 and we'll look for legitimate ways to lower the cost without cutting corners.
Licensing & Insurance FAQs
Every technician who works under the Brandt HVAC name in San Francisco is required to hold the license and insurance that California requires for HVAC work. That's not a nice-to-have. It's the baseline of the Threshold Standard. Before a tech steps into your home, they've been background-checked and identity-verified. You'll see their photo ID badge at the door, and you'll already know their name and face from the notice we sent before the visit. We don't cut corners on who we let into your home, because you shouldn't have to worry about it.
Threshold Verified is the set of standards every Brandt HVAC location operates under. It means every technician is background-checked, identity-verified, photo-badged, and sent to you by name and photo before the visit. They arrive in a clean, marked uniform and show their ID at the door, every time. The price is put in writing before any work starts. And if anyone arrives who you were not told to expect, that visit is on us and we make it right. Devin Marlowe's team in San Francisco follows this standard on every call, no exceptions.
Yes, we handle permitting for every job that requires it. San Francisco's Department of Building Inspection requires permits for most HVAC equipment changes, and we manage the paperwork, the scheduling, and the inspection coordination as part of the job. You shouldn't have to navigate the city's permit counter yourself, and you shouldn't be left wondering whether the work was done to code. If a project doesn't need a permit, we'll tell you that too. Either way, you'll know before the work starts. Call (559) 245-8807 with questions about your specific project.
Yes. Brandt HVAC San Francisco is an independently owned and operated local business that agreed to work to the Threshold Verified standard. The Brandt name comes from an old family name meaning firebrand, which felt like a natural fit for a heating company. The team here is led by Devin Marlowe, who runs the San Francisco branch and knows this city's housing stock, codes, and climate quirks. We're part of the Threshold Group family of brands, but the people who show up at your door are your neighbors, not a remote dispatch from another state.
Emergency & Response FAQs
We handle urgent heating and cooling repairs during our regular hours: Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. If your furnace quits on a cold night or your AC fails during an unusual San Francisco heat wave, call (559) 245-8807 as soon as you notice. We'll work to get you on the schedule as quickly as our hours allow. We understand that a failed heater in a 1920s Richmond District flat with single-pane windows is uncomfortable fast, and we treat those calls with the urgency they deserve.
Our hours are Monday through Friday from 7:00 AM to 7:00 PM, and Sunday from 7:00 AM to 7:00 PM. When you call during those hours, our live coordinator will connect you with the local team and get you on the schedule as soon as possible. We don't overpromise arrival windows we can't hit. What we do promise is that you'll know who's coming, when they're scheduled, and exactly what the price is before any work begins. That might not sound flashy, but it's the kind of reliability San Francisco homeowners tell us they want. Call (559) 245-8807 and we'll get moving.
First, check the simple things: make sure the thermostat is set to "heat" and the temperature is turned up, check that the circuit breaker hasn't tripped, and confirm the filter isn't so clogged it's choking airflow. If none of that fixes it, call (559) 245-8807 and leave a message. We'll get back to you as soon as our lines open. For safety, bundle up with extra blankets and close off unused rooms to trap heat in the spaces you're using. Don't run a gas oven for heat, and don't use outdoor propane heaters indoors. Call us in the morning and we'll get you sorted.
Warranty & Guarantees FAQs
Yes. Work performed by Brandt HVAC San Francisco is covered under the Threshold Verified promise. Every technician is background-checked, identity-verified, photo-badged, and sent to you by name and photo before the visit. If anyone arrives who you were not told to expect, that visit is on us and we make it right. That's the guarantee stamped on every page of this site and spelled out in our terms. We stand behind the work we do and the people who do it. If you ever have a concern about a completed job, call (559) 245-8807 and we'll address it directly.
Most HVAC equipment from brands like York, Bryant, American Standard, and Daikin comes with a 10-year parts warranty when the system is registered after installation. Some higher-tier units include a longer compressor or heat exchanger warranty. The key detail many homeowners miss: the warranty usually must be registered within 60 to 90 days of installation, or it drops to a shorter base warranty. We handle that registration for you when we install your system. We'll also explain exactly what's covered and for how long, in plain words, before you sign anything.
The most common warranty killers are skipped maintenance, unlicensed repairs, and unregistered equipment. Most manufacturers require proof of annual maintenance to keep the parts warranty valid, and they'll deny a claim if a non-licensed person worked on the unit. Using aftermarket or non-OEM parts can also void coverage. Registering your equipment on time matters more than most people realize. We register every system we install for our customers, and we'll remind you when it's time for the maintenance that keeps your warranty intact. Call (559) 245-8807 if you're unsure about your coverage.
If your system is under 10 years old and the repair costs less than a third of replacement, repair usually makes sense. If it's over 15 years old, uses R-22 refrigerant, or needs a major component like a compressor or heat exchanger, replacement is often the better long-term call. San Francisco's mild climate means most systems aren't run hard year-round, so a well-maintained unit can stretch past 15 years. We'll give you a straight answer on which path makes sense for your home and your budget. A written quote for both options means you decide with clear numbers in front of you.
