Complete Heating & Cooling Services for San Francisco Properties

We service every type of heating and cooling equipment you'll find in local homes and businesses, from central air conditioners and gas furnaces to heat pumps and ductless mini-splits. It doesn't matter whether the building is a starter home, a condo, or a busy office. Our techs understand the local weather, the age and construction of local homes, and the code requirements that apply to new installations, which pays off in the quality of every repair.

On the residential side, we take care of everything from quick fixes, like a failed capacitor, a pitted contactor, a dirty flame sensor, or a seized blower motor, to refrigerant leak repair, full system change-outs, and ductless additions. Every new system we install is sized with a proper load calculation instead of a rule of thumb, so you get even temperatures and reasonable utility bills instead of a unit that short-cycles itself to an early death. Our seasonal tune-ups clean coils, verify refrigerant charge, test safety controls, and check static pressure, the single best way to extend equipment life.

Commercial work is a big part of what we do too. We service rooftop units, split systems, and ventilation equipment for restaurant kitchens, shops, offices, and multi-unit properties, and we know that a day without cooling hurts the business. To keep disruptions short, we carry common parts on every truck, diagnose quickly, and schedule repairs around your operating hours whenever possible.

When Your System Fails in San Francisco

If your system quits, how quickly help shows up matters more than anything else. For that reason, we keep our schedule flexible across the area and put a real person on the phone. Emergency calls usually get a technician within a day, and we treat no-heat and no-cool calls as top priority.

Common emergencies we handle include air conditioners blowing warm air, outdoor units that hum but won't start, furnaces that ignite and then shut down, breakers that trip whenever the system starts, iced-over evaporator coils, clogged condensate drains backing up into the furnace cabinet, and thermostats that have stopped responding. Our trucks carry the capacitors, contactors, igniters, flame sensors, universal control boards, and fittings needed to finish most repairs in a single visit. We provide upfront pricing every time, so you know exactly what the work will cost before we begin.

If your AC has iced over, the best thing you can do before we arrive is switch the system off at the thermostat and set the fan to "on" so the coil can thaw. Running it frozen can flood the drain pan and strain the compressor. If a furnace is short-cycling or you smell something burning, turn it off at the service switch and call (510) 201-4731. A few minutes of caution can head off a much larger repair.

How San Francisco Homeowners Can Extend HVAC Life

The best way to avoid a mid-season breakdown is simple maintenance. We recommend that homeowners replace filters every one to three months, keep vegetation trimmed two feet back from the outdoor condenser, rinse the condenser coil each spring, and have a professional tune-up twice a year, cooling in spring and heating in fall, so small problems get caught while they're still inexpensive.

Take a look at the age of your system. That number says a lot about what comes next. With regular service, most air conditioners reach 12 to 15 years, gas furnaces 15 to 20, and heat pumps 10 to 15. If your system is beyond that range and also shows rising bills, uneven temperatures, or repeated repairs, it's a strong candidate for a planned replacement, and that's almost always cheaper and easier on everyone than an emergency replacement when the first heat wave hits.

Small problems don't stay minor for long. Take a weak capacitor: swapping it out is a quick, affordable repair, but left alone for a season, it can burn out the compressor, and suddenly a minor fix becomes a full system replacement. That's why we ask homeowners to keep our number in their phone and call at the first hint of trouble. Catching it early saves time and money and prevents a miserable night.

Common HVAC Problems in San Francisco

The service calls we run around here follow familiar patterns. In summer it's air conditioners humming but not cooling, weak capacitors that finally quit on the first hot week, and condensate drains backing up into the furnace cabinet. In winter it's furnaces that short-cycle, dirty flame sensors, and igniters that fail on the first cold night. Year-round we see clogged filters choking airflow, rising energy bills from dirty coils, and ductwork that leaks conditioned air into attics and crawlspaces. Every one of these starts small, and every one is cheaper to fix early. If your system is acting up, call (510) 201-4731 before the season turns it into an emergency.

The Reason San Francisco Keeps Calling Us

Plenty of companies will happily sell you a new system. Oakland HVAC earns trust around here by fixing the ones that don't need replacing and being honest about the ones that do. Our technicians diagnose the actual fault before quoting anything, explain your options in plain language with real numbers, and let you decide without pressure. When replacement is the right call, we size the new system with a proper load calculation for your home's genuine demand, square footage, insulation, windows, and duct capacity, instead of defaulting to whatever's in the warehouse.

The workmanship holds up because we sweat the details: correct refrigerant charge weighed in rather than guessed, sealed duct connections, proper condensate drainage, verified combustion and airflow on heating equipment, and clean electrical work that passes inspection without drama. We show up when we said we would, cover your floors, haul away the old equipment, and test the full system in every mode before we leave. It's why so much of our local work comes from repeat customers and referrals, and why we back every job with a satisfaction guarantee.

Common Heating & Cooling Questions

Start with a few quick checks: confirm the thermostat is set to cool with working batteries, pull the filter and check for a clog, and look for a tripped breaker on both the indoor and outdoor units. If everything looks normal and the outdoor unit hums but won't start, or you see ice on the copper lines, turn the system off to protect the compressor. Then call (510) 201-4731 and we'll send a technician to your home as fast as we can.
Most repairs land between $150 and $650 depending on the part and system type, while full system replacements typically run from around $5,000 to $12,000 installed, depending on size and efficiency. Every job starts with a diagnostic and a written, upfront quote. The price you approve is the price you pay, with no surprises added later.
We do both. Most visits begin as a repair, and our technicians work on air conditioners, furnaces, heat pumps, and ductless mini-splits from every major brand. When a system can't be saved, we take care of the full replacement, from the load calculation and hauling off the old unit to installation and testing in every mode. Whichever way it goes, you'll see a written quote for both options before anything happens.
Fast. We serve the whole area with same-day appointments for most calls, and no-heat and no-AC calls get top priority. Our trucks carry the most common parts, including capacitors, contactors, igniters, and motors, so the majority of repairs are diagnosed and finished in a single visit. Call (510) 201-4731 and we'll give you an honest arrival window.
Absolutely. Mini-splits are ideal for additions, garages, sunrooms, and older homes that never had ductwork. We size each zone to the actual room, position the indoor and outdoor units thoughtfully, and handle the line set, condensate drainage, and electrical connections correctly. If a ducted system is the better fit, we'll tell you that too.
We work on just about everything installed in local homes, from Carrier, Trane, and Lennox to Rheem, Goodman, and York, along with ductless equipment from Mitsubishi, Fujitsu, and LG. Universal parts on the truck cover most units, and when a repair needs a brand-specific component, we track it down fast.
Yes, and for most homeowners it's the best thing you can do for your equipment. Twice a year, a technician cleans the coils and burners, checks the refrigerant charge and combustion, tests capacitors and safety controls, and measures airflow from supply to return. Catching problems at a tune-up is far cheaper than a breakdown in the middle of summer, and lower energy bills often cover the cost of the visit.
There's no single cutoff, but a few rules of thumb help. Most component failures on systems under about 10 years old are worth the repair. After roughly 15 years, or after a failed compressor or cracked heat exchanger at any age, replacing the system usually makes better financial sense, especially with the efficiency gains newer equipment offers. We'll show you both numbers honestly and let you decide, because we'd rather earn your trust than sell you a system early.
