AC maintenance in San Francisco typically runs between $95 and $235 for a full AC Maintenance - San Francisco tune-up, and it’s the single best way to prevent the repair calls that hit hardest during our late-summer heat waves. Brandt HVAC Co San Francisco has been keeping Bay Area cooling systems running since 2003, and every visit starts with something most companies skip: a technician’s name and photo sent to you before arrival. When Devin Marlowe schedules your maintenance, you’ll know exactly who’s walking up the driveway. If you want a written price before any work begins and a live person on the phone at any hour, call (559) 245-8807.
We built our maintenance service around a plain fact: San Francisco’s cool maritime air hides a lot of AC problems until the first genuinely hot day. Then every unit in the city strains at once, and repairs get expensive. Regular maintenance catches those failures while they’re still cheap to fix.
Air Conditioner Maintenance
Air Conditioner Maintenance is the routine cleaning, inspection, and adjustment work that keeps your cooling system efficient and catches small problems before they become mid-August breakdowns. In San Francisco, the ideal window is early spring, before the marine layer lifts and temperatures climb. Brandt HVAC Co San Francisco performs a full maintenance visit for $95 to $235 depending on system size and condition, with a written price confirmed before any work starts.
What Gets Checked
We clean or replace air filters, clear the condensate drain line, and measure refrigerant levels against manufacturer specs. A low charge means a leak somewhere, and we’ll find it before it roasts your compressor.
Coastal Air, Coastal Wear
San Francisco’s salt air and fog accelerate corrosion on condenser coils and electrical contacts, especially in the Outer Sunset, Richmond, and anywhere west of Twin Peaks, so Daly City AC Maintenance customers nearby face similar conditions. Our maintenance includes contact cleaning and coil inspection that’s calibrated for exactly this microclimate.
Styles & brands we work with







HVAC Maintenance
HVAC Maintenance covers the entire heating and cooling system in one visit: the AC condenser, the furnace or heat pump, the thermostat, and the ductwork connections that tie them together, including systems we service for AC Maintenance - South San Francisco. You need it twice a year in San Francisco’s climate, once before cooling season and once before heating season, because our milder averages still include real temperature swings. Brandt HVAC Co San Francisco combines both into a single check for $95 to $235, written up front.
Furnace Side, Too
Many Bay Area homes run the furnace in the morning and the AC by afternoon during shoulder season. We inspect burners, heat exchangers, and flue connections on the heating side so the switchover doesn’t surprise you.
One Visit, Whole System
A combined maintenance call takes about 90 minutes and produces a written report of everything we found. You’ll know what’s healthy, what’s wearing, and what can wait until next season.
AC Tune Up
AC Tune Up is the hands-on portion of maintenance: the adjustments, lubrication, and calibrations that return your system to factory performance. You need it annually, and you’ll notice the difference in higher airflow, shorter run times, and lower PG&E bills. Brandt HVAC Co San Francisco charges $95 to $235 for a tune-up, with a flat written quote before we touch a screw.
Efficiency That Shows Up on the Bill
A dirty coil or a slipping blower belt can add 10 to 15 percent to your cooling cost without changing your comfort. We measure temperature drop across the coil, check blower amps, and set the refrigerant charge to manufacturer specifications.
The Report You Keep
After every tune-up, you receive a written summary of measured values: coil temperature split, refrigerant pressures, amp draws, and airflow. That baseline makes future issues easier to spot, and if we recommend a repair, you’ll see the exact numbers backing it.
HVAC Maintenance Service
HVAC Maintenance Service is the ongoing relationship, not just a one-time visit: scheduled tune-ups, priority scheduling for repairs, and a written history of your system’s condition over time. You need it if your system is more than five years old or if you want firm control over repair costs before they happen. Brandt HVAC Co San Francisco offers maintenance service at $95 to $235 per visit, with no contract required and no surprise fees.
Priority When It Counts
Maintenance customers get first scheduling priority when San Francisco gets one of its rare heat spikes. When every unit in the city goes down the same week, you don’t want to be at the bottom of a call list.
History That Pays Off
We keep a written record of every visit, every measurement, and every part replaced. When something does fail, that history shortens diagnosis time and often narrows the repair to a single component.
HVAC Tune Up
HVAC Tune Up is the periodic adjustment of both heating and cooling sides so the entire system runs at peak efficiency whatever the season. Schedule it twice a year in San Francisco, spring and fall, and you’ll rarely face an emergency call. Brandt HVAC Co San Francisco provides a combined HVAC tune-up for $95 to $235, priced in writing before we begin.
What Gets Adjusted
We set gas pressures and burner alignment on the furnace side, then switch to refrigerant pressures and blower speeds on the AC side. Thermostat calibration happens last, so the whole system responds as one unit.
Seasonal Shift Protection
San Francisco’s mid-September heat and January cold snaps put real stress on systems that sit idle for months at a time. A fall tune-up catches heating issues before the first cold night, and a spring tune-up catches AC issues before the first hot afternoon.
Brands We Service
York units have a long history in Bay Area apartments and single-family homes, and we stock their OEM contactors and capacitors so a tune-up can turn into a same-visit fix. Daikin systems, especially the ductless mini-splits common in older San Francisco buildings, get careful coil cleaning and drain-line service, which is where those units most often fail in our damp climate. Bryant equipment responds well to precise refrigerant charging, and we follow the manufacturer’s published charge tables rather than guesswork.
Whether you have a York, a Daikin, a Bryant, or any other make, we can help. Brandt HVAC Co San Francisco services Carrier, Trane, Lennox, Goodman, Rheem, American Standard, and the rest of the residential market. Your tune-up comes with the same written price and the same 365-Day Done Right Promise no matter what’s bolted to your wall.

- Warm air blowing from the vents. This usually means low refrigerant or a failing compressor, and running the system in this state makes the damage worse. Call us before the compressor seizes, because that’s the difference between a $200 recharge and a $4,000 replacement.
- Ice forming on the copper lines or the indoor coil. Ice is a sign of restricted airflow or low charge, and it insulates the coil so the system can’t absorb heat. Shut the AC off and call, because melting ice can flood the electrical compartment.
- Breaker trips when the AC kicks on. A compressor drawing too many amps or a shorted fan motor will trip the breaker repeatedly. This is an electrical fault and it won’t fix itself; it gets more dangerous with every reset.
- Any burning smell from the vents when you switch to heat. Dust burning off the heat exchanger is normal for the first few minutes of the season, but a persistent acrid or plastic smell means wiring or a control board is overheating. Treat it as urgent and shut the system down.
- Water pooling around the indoor unit. A clogged condensate drain can back up into your wall or ceiling in San Francisco’s humid summer weeks. By the time you see water, the drain has been blocked for a while and the overflow switch may be about to fail.
Our Process, Step by Step
- 1
You book, and you learn who’s coming. When you schedule, we send a confirmation with your technician’s name and photo. That technician arrives in a Brandt HVAC uniform with a photo ID badge shown at the door, part of our Threshold Verified standard. If the person at your door is not the person we told you to expect, we make it right, on us.
- 2
We walk the system with you. Your technician starts by asking what you’ve noticed about comfort, noise, and bills. Then we inspect the equipment and show you what we’re seeing, whether it’s a dirty filter, a corroded contact, or a refrigerant level that’s dropped since last year.
- 3
You approve a written price. Before any work starts, you get a written quote showing exactly what the tune-up includes and what it costs. No add-ons appear later, no overtime fees, no surprises. You sign, and then we start.
- 4
We perform the full maintenance checklist. This includes coil cleaning, filter replacement or cleaning, condensate drain clearing, electrical connection tightening, refrigerant measurement, blower inspection, thermostat calibration, and a full system test cycle. We use digital gauges and amp meters so the readings are accurate, not estimated.
- 5
You get a written report and a guarantee. We summarize every measurement, every adjustment, and any repair we recommend with a plain-language explanation. If we do perform a repair during the visit, it’s covered by our 365-Day Done Right Promise. If it fails within that year, we return free of charge and make it right.
How Much Does AC Maintenance Cost in San Francisco?
A typical AC tune-up in San Francisco runs $95 to $235 depending on the system type, its age, and whether the condenser and air handler are easily accessible. A standard single-family home with a conventional split system lands in the middle of that range, around $150 to $180. A larger home with zoned ductwork or a multi-unit building with several air handlers costs toward the higher end. Older systems, especially units over 12 years with original capacitors and contactors, may need extra attention during the same visit, and those parts push the bill toward the top of the range.
What affects the price? System size is the biggest factor: more tonnage means more coil surface to clean and more refrigerant to verify. Accessibility matters too. A rooftop unit on a five-story Noe Valley walkup takes longer to reach than a ground-level condenser in the Sunset. The condition of the system plays in as well: if the previous maintenance was years ago, there’s more to clean, more to measure, and more to bring back to spec.
How do you avoid overpaying? Get a written price before any work starts. Brandt HVAC Co San Francisco gives every customer a fixed quote on paper, and if the technician finds something that needs a repair, you’ll see the exact cost of that repair in writing before we do it. No mystery charges, no phone call half an hour into the job with bad news. Your written quote is your estimate, and it’s free. Call (559) 245-8807 to get yours.
