Trusted San Francisco HVAC Service
San Francisco homeowners don't call an HVAC company on a good day. They call when the AC dies in a heat wave, when the furnace clicks but never lights, when one bedroom stays ice cold no matter what the thermostat says. Temecula HVAC built its local reputation on those calls: picking up the phone, arriving with stocked trucks, and solving the real problem on the first visit. From quick capacitor swaps to full heat pump installations, our technicians handle every job with upfront pricing and no pressure, and we treat your home like it belongs to a neighbor, because around here, it does.

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 single-family house, a condo, or a busy office. Our technicians understand the local weather, the age and construction of local homes, and the code requirements inspectors enforce, which pays off in every diagnosis.
Most homeowners we meet need one of three things: a repair, a replacement, or regular maintenance. Repairs tend to be quick: a burned contactor, a dirty flame sensor, a slow refrigerant leak, or a worn-out blower motor. Replacements get a proper load calculation, not a guess based on the old unit's tonnage, which keeps temperatures even and stops the new equipment from short-cycling its way to an early failure. Tune-ups cover coil cleaning, a refrigerant charge check, safety control testing, and a static pressure reading, and nothing does more to extend equipment life.
Commercial work makes up a large share of our work as well. We service rooftop units, split systems, and ventilation equipment for restaurant kitchens, shops, offices, and multi-unit buildings, knowing that a day without cooling hurts your bottom line. To keep disruptions short, we carry common parts on every truck, diagnose quickly, and schedule larger jobs around your operating hours whenever possible.
Quick Heating and Cooling Help 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 speak with a real person who gets a technician headed to your property quickly. Our typical arrival window 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.
The urgent calls we run usually follow a pattern. On the cooling side, it's an AC blowing warm air, an outdoor unit that hums without starting, or an evaporator coil iced over. On the heating side, it's a furnace that lights and then shuts down. Year-round, it's breakers that trip whenever the system starts, plugged condensate drains overflowing into the furnace cabinet, and thermostats that stop responding. Since our trucks are stocked with capacitors, contactors, igniters, flame sensors, universal control boards, and fittings, the majority of these calls get fixed on the first trip, with the price agreed before any work begins.
If your AC has iced over, the most helpful 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 (951) 209-0257. A few minutes of caution can head off a much larger repair.
How San Francisco Homeowners Can Extend HVAC Life
Many mid-season breakdowns start with skipped maintenance, and the habits that prevent them are easy. Swap 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 each spring and fall, one for cooling and one for heating, so our technicians can catch small problems while they're still cheap to fix.
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 showing symptoms, 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 during the first heat wave of summer.
The sooner you call about a comfort problem, the smaller the repair tends to be. A capacitor that's starting to fail is an easy, low-cost part to replace, yet that same capacitor, neglected through a full season, can ruin the compressor and force a full system replacement. Save our number on your phone today so help is one call away as soon as something seems off in your home. A quick call saves time, money, and sleepless nights.
Comfort Challenges San Francisco Homeowners Face
Most local HVAC failures give warning signs before they happen. A breaker that trips every few days, a condenser that hums louder each month, rooms drifting further from the thermostat setting, energy bills creeping up with nothing else changed. These are the early symptoms of failing capacitors, refrigerant leaks, dirty coils, and duct problems, and caught early they're an affordable repair. Ignored, they take out compressors and heat exchangers, the two most expensive parts in the system. We diagnose the cause, not just the symptom, so small problems stay small.
