When your air conditioner quits during a fog-belt heat wave or a Mission District Indian summer, you need a repair crew that shows up when they say they will, tells you the price before touching a single component, and fixes it right the first time. Brandt HVAC Co San Francisco has been repairing residential cooling systems since 2003, and we send every technician to your door by name and photo before they arrive. You’ll know exactly who is walking up your steps, their background is verified under the Threshold Verified standard, and the price is written down before any work begins. If you’re wondering how much AC Repair costs, most jobs in San Francisco run $175 – $765, and we’re available same-day when the heat is on. Call (559) 245-8807 and a live person answers, 24 hours a day.
AC Service
AC Service covers everything from a seasonal inspection to a targeted fix for a system that’s running but not performing the way it should. It’s what you need when your unit is short-cycling, making a new noise, or your energy bill climbed for no obvious reason. In San Francisco, where microclimates swing from the Sunset’s chill to the Excelsior’s heat, a system that works hard in the afternoon needs honest diagnosis. Brandt HVAC Co San Francisco charges $175 – $765 for most AC Service calls, with the exact price written down and agreed to before work starts. That range covers straightforward fixes like thermostat recalibration, drainage clearing, and electrical connection tightening.
Seasonal and As-Needed Tune-Ups
Following an AC Repair Maintenance Checklist for San Francisco Homeowners before summer hits is cheap insurance against a failure during the first real heat spike. We check refrigerant pressure, airflow, electrical draw, and condensate drainage, then give you a written report of what we found and what it costs to fix.
Diagnosis Without Pressure
Our technicians are not paid on what they sell. When we find a problem, we show it to you, explain it in plain language, and quote a fixed price. If it’s a small fix, you’ll know in the same visit.
Styles & brands we work with
AC Unit Repair
AC Unit Repair means repairing the actual cooling unit itself – the condenser outside, the evaporator coil inside, the compressor, the fan motor, or the control board. It’s what you need when the system runs but can’t hold temperature, or when a specific component fails outright. Most AC Unit Repair jobs in San Francisco fall between $175 and $765, depending on whether we’re replacing a contactor, a fan motor, or a capacitor along with labor. Brandt HVAC Co San Francisco diagnoses the exact failure, shows you the failed part, and quotes a fixed price that includes the part and the labor before we turn a single screw.
Compressor and Coil Concerns
Compressor and coil failures are the two most expensive repairs on a residential system. We test electrical draw and refrigerant pressures to determine whether the compressor is genuinely failing or being dragged down by a $50 component upstream.
Electrical and Control Repairs
Loose terminals, failed relays, and fried control boards are common in San Francisco’s salt air, especially near the ocean. We replace the failed board or relay, torque the connections to spec, and test the full start-up sequence before we leave.
AC Capacitor Replacement
AC Capacitor Replacement is the most common AC repair we do, period. The capacitor is the component that gives your compressor and fan motor the electrical kick they need to start, and when it fails, the unit either hums and won’t start or the fan stops spinning while the compressor cooks itself. It’s a $175 – $365 repair in San Francisco for most single and dual-run capacitors, parts and labor included. Brandt HVAC Co San Francisco keeps common capacitor values stocked on every truck, so this is typically a same-visit fix. We test the old capacitor under load, confirm the microfarad reading is out of spec, show you the reading, and install the correct replacement.
Signs Your Capacitor Is Failing
A unit that hums but won’t start, a fan that needs a push with a stick to get going, or a compressor that kicks on and off every few minutes are all classic capacitor symptoms. Left unrepaired, a weak capacitor forces the compressor to run hot and shortens its life substantially.
Why Same-Day Repair Matters Here
A failed capacitor in a San Francisco apartment building on an 85-degree day is not just uncomfortable – it’s unsafe for older residents and small children. We prioritize capacitor failures for same-day service because the fix is fast and the relief is immediate.
AC Recharge
AC Recharge means refilling the refrigerant in your system – the fluid that absorbs heat from inside your home and releases it outside. When refrigerant runs low, the system can’t pull heat out of the air, and that’s when rooms start feeling clammy instead of cool. A recharge in San Francisco typically runs $175 – $465 depending on the refrigerant type and how much the system takes. Brandt HVAC Co San Francisco locates the leak, repairs it if it’s accessible, and recharges to the manufacturer’s exact specification. A recharge without finding the leak is a temporary patch, and we will not do that to you.
Low Refrigerant Causes and Detection
Refrigerant is not consumed like fuel – it circulates in a sealed loop. Low levels mean a leak somewhere, most often at a braze joint, a Schrader valve, or a coil. We use electronic leak detectors and UV dye to find it before adding anything.
R-22 vs. R-410A
Older San Francisco homes built before 2010 often have R-22 systems, and R-22 is no longer manufactured in the US, which drives its price up every year. We will tell you honestly whether a recharge makes sense or whether that money is better put toward a newer system.
Emergency AC Repair
Emergency AC Repair is what you need when the system fails completely during a heat event, or when you have a household member with a health condition, a newborn, or an elderly parent in the heat. It means a live person answers at 2 a.m., a technician is dispatched that day, and the repair happens fast. Brandt HVAC Co San Francisco charges the same rates for emergency calls that we charge for regular calls – $175 – $765 for most repairs, with no overtime surcharge and no “emergency fee” added on. A live person answers our phone around the clock, every day of the week.
What Counts as a Real Emergency
Complete system failure on a hot day, a burning smell from the unit, water pouring through a ceiling, or a compressor that’s screaming. If a person in the home is medically vulnerable to heat, every hour counts, and we treat that as a priority dispatch.
Same-Night Response, Not a Callback Queue
You will not get a voicemail tree when you call us. You’ll get a person who takes your address, confirms the technician’s name and ETA, and sends a photo to your phone before the truck rolls.
AC Not Blowing Cold Air
AC Not Blowing Cold Air is the number one reason San Francisco homeowners call us. The fan runs, the thermostat says 72, but the air coming out of the vents feels lukewarm or weak. The cause can be anything from a dirty filter and low refrigerant to a failed compressor or a frozen evaporator coil. Brandt HVAC Co San Francisco diagnoses this in one visit, quotes you a written price between $175 and $765 for the typical repair, and fixes it the same day in most cases. We start with airflow and temperature measurements, then work backward from the symptom to the cause.
Frozen Coils and Thawing Time
A frozen evaporator coil is one of the most common causes of warm air, and it usually means low airflow or low refrigerant. We thaw the coil properly, find the root cause, and test the system under full load before we hand it back to you.
Airflow Restrictions You Can Check
Before you call, check the most common airflow killers: the filter, closed or blocked supply vents, and debris around the outdoor condenser. In San Francisco’s older Victorians and Edwardians, people often close vents in unused rooms, and that backpressure causes the coil to freeze.
Brands We Service
We repair York systems routinely, and our technicians know the quirks of York compressors and their affinity for specific capacitor ranges. If you have a York unit that’s short-cycling or tripping the breaker, we’ll have the right parts on the truck the first time.
We also service Daikin and Bryant units across San Francisco, from the older Bryant evaporator coils common in 1990s condos to Daikin mini-splits in newer remodels. Whether you have a York, Daikin, Bryant, or any other make, we can help – and we’ll tell you the truth about whether your unit is worth repairing.

- Warm air from the vent. If the air coming out of your supply vents is the same temperature as the room or warmer, the system isn’t cooling. That’s not a “keep an eye on it” situation – it’s a failed component or low refrigerant inviting a bigger repair.
- Ice on the refrigerant lines or coil. Frost or ice on the copper lines at the outdoor unit, or on the indoor coil itself, means the system is starving for airflow or refrigerant. Running it frozen can destroy the compressor, which turns a $300 repair into a $4,000 replacement.
- Humming, buzzing, or clicking without startup. Those are the sounds of a capacitor failing or a contactor chattering. If the compressor can’t start, it’s pulling locked-rotor amps every time it tries, and that heat is cooking the windings. Shut it off and call us.
- Water pooling around the indoor unit. A clogged condensate drain or a frozen coil that’s now thawing will dump water where it shouldn’t. In San Francisco’s older homes, that water hits plaster, hardwood, or electrical before you know it.
- Electrical or burning smells. A scorched wire, a failing blower motor, or a burned control board can smell like hot plastic or burnt dust. Shut the system off at the breaker and call. This is not a repair to diagnose by smell alone.
Our Process, Step by Step
- 1
You call, a person answers. Day or night, weekday or holiday, a live person picks up. We take your address, your symptom description, and schedule a window that works. Before the technician leaves the shop, you get a text with their name and photo.
- 2
We arrive, we badge, we explain. The technician shows you their photo ID at the door, wears a Brandt HVAC uniform, and explains what they’ll inspect. If anyone arrives who you were not told to expect, that visit is on us, per the Threshold Verified standard.
- 3
We diagnose with instruments, not guesses. We check refrigerant pressures with manifold gauges, measure capacitor microfarads under load, test electrical draw, and measure temperature split across the coil. We find the actual cause before we quote anything.
- 4
You approve a written price. No work starts until you see the exact price, in writing, for the exact part and labor. No surprises at the end. No “while we were in there” add-ons.
- 5
We repair, test, and guarantee it in writing. We install the part, run the system through a full start-up cycle, measure the output temperature, and hand you a written guarantee for the repair. If it fails within 365 days, we return at no charge under the 365-Day Done Right Promise.
How Much Does AC Repair Cost in San Francisco?
Most AC repairs in San Francisco run $175 – $765, with the final number driven by which component failed and how easy it is to access. A capacitor replacement is the most common fix and lands at the lower end, typically $175 – $365 including the part and labor. A blower motor, control board, or refrigerant recharge pushes into the $350 – $600 range. A compressor or evaporator coil replacement is at the top end, and we’ll always tell you if the smarter financial move is a new system instead of a repair. The factors that move the price: the refrigerant type, the age and brand of the unit, and whether the failed part is stocked on our truck or needs to be ordered. To avoid overpaying, get a written price before any work starts, ask whether the quote includes the part or just the labor, and be wary of any company that wants to replace a multi-thousand-dollar component without showing you the failed part. Our estimates are free and come with a written price for the exact repair we recommend. Call (559) 245-8807.
