Full-Service HVAC Care for San Francisco Homes and Businesses

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 makes no difference whether the building is a single-family house, a townhome, or a busy office. Our techs know the local climate, the way homes here were built, and the code requirements that apply to new installations, which pays off in every diagnosis.

On the residential side, we take care of everything from quick fixes, like a weak capacitor, a pitted contactor, a dirty flame sensor, or a seized blower motor, to refrigerant leak repair, complete system replacements, 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. Seasonal maintenance visits clean coils, verify refrigerant charge, test safety controls, and check static pressure, still the most reliable way to extend equipment life.

For commercial property owners and managers nearby, we service the rooftop units, split systems, and makeup air and ventilation equipment that restaurants, retail spaces, offices, and multi-unit buildings depend on. We understand that a hot dining room or a freezing office means lost business, so we prioritize fast diagnosis, stock common parts on the truck, and schedule work around your operating hours whenever we can.

When Your System Fails in San Francisco

Heating and cooling failures rarely wait for a convenient day, which is why we offer prompt, flexible scheduling for most situations. When you call, you'll reach a real person who will get a technician headed to your property without delay. Arrival in the area is typically within a day for urgent calls, and a dead AC in a heat wave or a furnace out on a freezing night is the kind of call we move to the front of the line.

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, frozen 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 complete most repairs in a single visit. Pricing is always upfront, 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 damage the compressor. If a furnace is short-cycling or you smell something burning, shut it down at the switch and call (714) 650-8571. A few minutes of caution can prevent a much larger repair.

How San Francisco Homeowners Can Extend HVAC Life

Many mid-season breakdowns start with maintenance that never happened, and the habits that prevent them are easy. Change your filter every one to three months, clear vegetation at least two feet from the outdoor condenser, and hose off the condenser coil every spring. Then book a professional tune-up twice a year, one for cooling and one for heating, so our technicians can catch small problems while they're still cheap to fix.

The age of your equipment matters just as much. With regular service, a central air conditioner usually runs 12 to 15 years, a furnace 15 to 20, and a heat pump 10 to 15. Once a system passes that range and starts showing warning signs, like rising energy bills, rooms that never reach the setpoint, or one repair after another, it's smart to start planning a replacement. Replacing on your own schedule costs less and is far less stressful than an emergency swap during the first heat wave of the year.

If comfort problems do show up, acting quickly keeps them small. A weak capacitor is a quick fix. The same capacitor ignored for a season can take the compressor with it and turn a minor repair into a full system replacement. It's smart to keep our number saved on your phone so you can reach us at the first sign of trouble. Early intervention saves time, money, and miserable nights.

Common HVAC Problems in San Francisco

HVAC systems in this area face a familiar set of problems. Hard-running summers push compressors and capacitors to their limits, and salt air and moisture chew at outdoor condenser coils and fins, cutting efficiency years before the equipment should show its age. Dirty filters quietly starve systems of airflow, freezing evaporator coils in summer and overheating furnace heat exchangers in winter, a slow kind of damage most homeowners never see coming.

We also see the full range of component failures in local homes: weak capacitors that leave the condenser humming without starting, contactors with pitted points, cracked igniters and dirty flame sensors that lock furnaces out on cold mornings, refrigerant leaks that turn into long lukewarm afternoons, and blower motors worn down by years of restricted airflow. The area's mix of older homes brings undersized returns, leaky duct runs, and rooms the original system was never designed to condition.

Every one of these problems is fixable, and most are much less expensive when caught early. If your system is doing anything unusual, strange noises, weak airflow, rooms that won't hold temperature, bills creeping upward, a quick diagnostic visit from our team catches the small problem before it becomes a costly breakdown. Give us a call at (714) 650-8571 to set up a visit.

Your HVAC Questions Answered

Yes. We repair all major brands of air conditioners, furnaces, heat pumps, and ductless mini-splits. When a system is beyond saving, we handle the complete replacement: hauling away the old equipment, putting in a correctly sized new system, and testing it in every mode. You get a clear quote for each option before deciding.
We work on nearly every brand installed in local homes, from Carrier, Trane, and Lennox to Rheem, Goodman, and York, along with ductless systems from Mitsubishi, Fujitsu, and LG. The universal parts on our trucks fit most units, and if a job needs a factory part, we track it down fast.
It comes down to age and which part failed. Under about 10 years, most component failures are well worth repairing. Past 15 years, or any time a compressor or heat exchanger fails, replacement is usually the smarter money, especially with the efficiency gains of new equipment. We give you both numbers straight and let you make the call. We'd rather earn your trust than sell you a system early.
In many cases, yes. Ductless mini-splits shine in room additions, converted garages, sunrooms, and older homes that never had ducts. Our approach begins with sizing each zone for the real load of that room, followed by thoughtful placement of the indoor and outdoor units and a clean install of the line set, condensate drainage, and electrical connections. If central equipment would be the better choice for your home, we'll let you know.
We always quote before we start, so you know the price up front. As a general range, typical repairs cost $150 to $650 depending on the part and system, and full replacements run roughly $5,000 to $12,000 installed based on size and efficiency. Your exact price comes from an on-site diagnostic at your home, and the quote you sign off on is the price you pay, no surprises added later.
First, rule out the easy stuff. Make sure the thermostat is in cooling mode with good batteries, replace the filter if it's dirty, and look at the breakers for the indoor and outdoor units. Ice on the copper lines or an outdoor unit that hums but never starts is your signal to shut the system off, because continuing to run it risks damaging the compressor. Call us at (714) 650-8571 and we'll send a technician your way right away.
Yes. Our seasonal tune-ups clean coils and burners, verify refrigerant charge and combustion, test capacitors and safety controls, and check airflow through the whole system, with cooling in spring and heating in fall. It's the most reliable way to extend equipment life and avoid a breakdown in the middle of a summer heat wave or winter cold snap, and it often pays for itself in energy savings over time.
Most calls are scheduled the same day, and a home with no heat or no cooling gets priority over routine work. When you call at (714) 650-8571, you'll get a realistic arrival window, and since the technician shows up with capacitors, contactors, igniters, and motors on the truck, the job usually wraps up in one trip.
