Professional HVAC Service in San Francisco

For San Francisco residents, Newark HVAC is the shortcut past every bad HVAC experience you've heard about: the vague quotes, the mystery invoices, the replacement pitch for a system that needed a $40 part. We do it differently. You talk to a real person, a technician shows up on time, the diagnosis is explained clearly, and the price is agreed before any work begins. Repairs, installations, duct cleaning, and seasonal maintenance, all handled by experienced pros who know the area.

Heating and Air Conditioning Service Across San Francisco

Heating and cooling around here covers a lot of ground: older gas furnaces on the older streets, newer heat pumps in recent construction, ductless mini-splits in additions and converted garages, and packaged units on commercial buildings. Our team handles all of it. Our technicians have years in the field, and we know how the local climate, the age of local homes, and code requirements affect the way a system runs and fails.

On the residential side, we take care of everything from quick fixes, like a failed capacitor, a burned contactor, a dirty flame sensor, or a seized blower motor, to refrigerant leak repair, full system change-outs, and ductless additions. We size every new system with a proper load calculation rather than guesswork, 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.

For commercial property owners and managers nearby, we service the rooftop units, split systems, and dedicated ventilation equipment that restaurants, retail spaces, offices, and multi-unit buildings depend on. Our commercial team understands that a hot dining room or a freezing office means lost business, so we prioritize fast diagnosis, carry 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 dispatched to your door 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 exactly 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 finish most repairs in a single visit. Pricing is always upfront, so you know exactly what the work will cost before we begin.

Two common situations call for quick action from you before a technician arrives. The first is an iced-over air conditioner: turn the system off at the thermostat and set the fan to "on" so warm indoor air thaws the coil, because running it frozen can flood the drain pan and hurt the compressor. The second is a furnace that keeps cycling on and off or produces a burning smell. Shut it down at the switch and call us. That small step can save you from a much larger repair.

Keeping Your San Francisco HVAC System Running Longer

A little routine care makes all the difference between a system that runs for years and one that breaks down in the middle of a heat wave. Our advice for homeowners is a short list: fresh filters every one to three months, two feet of clearance around the outdoor condenser, a gentle rinse each spring for the condenser coil, and a professional tune-up every spring and fall, so small issues get caught early.

Age matters too. Most central air conditioners last 12 to 15 years, furnaces 15 to 20, and heat pumps 10 to 15 with regular service. If your system is past that window and starting to struggle, such as rising energy bills, rooms that never quite reach temperature, or repairs stacking up season after season, a planned replacement is nearly always less expensive and much easier on you than an emergency one in the middle of a cold snap.

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.

Typical Heating & Cooling Issues 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 humidity and airborne grit slowly foul outdoor condenser coils, 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.

Our technicians also run into the full range of component failures in local homes: capacitors that leave the outdoor unit humming but not 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 (510) 201-4778 to set up a visit.

The Reason San Francisco Keeps Calling Us

Choosing an HVAC company comes down to trust, and trust has to be earned. Newark HVAC earns it by recommending the $150 repair when that's what the system needs, by sizing replacements with real load calculations instead of guesswork, and by standing behind every repair long after the visit ends. Same-day service is available for most calls, and every visit ends with the system tested and your questions answered.

Common Heating & Cooling Questions

Fast. We serve the whole area with same-day appointments for most calls, and no-heat and no-cooling emergencies get top priority. Our trucks are stocked with 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) 201-4778 and we'll give you an honest arrival window.
Check the thermostat mode and batteries, the air filter, and the breakers for both the indoor and outdoor units. If the outdoor unit hums but won't start, or ice has built up on the refrigerant lines, shut the system off so the compressor isn't damaged and call us at (510) 201-4778. We'll get a technician moving your way right away.
Age and the failed part decide it together. Under about 10 years, most component failures are worth fixing. Past 15 years, or any time a compressor or heat exchanger fails, replacement is usually the smarter investment, especially given how much more efficient new equipment is. We give you both numbers honestly and let you make the call. We'd rather earn your trust than sell you a system before you need one.
It depends on the job. Repairs usually come in between $150 and $650, based on the failed part and the type of system. A full replacement typically costs around $5,000 to $12,000 installed, depending on size and efficiency rating. Before we begin, you'll get a written quote based on the diagnostic, and that number doesn't change.
Yes, and a mini-split is often the best answer for additions, garages, sunrooms, and older homes built without ductwork. Every zone is sized to the actual load of its room. We map out where the indoor and outdoor units go and install the line set, condensate drain, and electrical work properly. And we'll be upfront if central equipment makes more sense for your home.
Yes. Our seasonal tune-ups clean coils and burners, verify refrigerant charge and combustion, test capacitors and safety controls, and check airflow end to end, with a cooling visit in spring and a heating visit 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 usually pays for itself in energy savings over time.
Every major brand, including Carrier, Trane, Lennox, Rheem, Goodman, and York, plus ductless systems from Mitsubishi, Fujitsu, and LG. Our technicians carry universal parts that fit most units and can source brand-specific components quickly when a repair requires them.
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. If repair no longer makes sense, we take care of the whole replacement, from the load calculation and removing the old unit to installation and testing in every mode. Either way, you'll see a written quote for both options before you decide.
