Complete Heating & Cooling Services for San Francisco Properties

Whether you own a townhouse, a rental property, or a commercial space in town, we have the expertise and equipment to handle the full range of heating and cooling work. Our technicians bring years of hands-on experience with central air conditioners, gas and electric furnaces, heat pumps, and ductless mini-splits throughout the area, and we understand the climate patterns, housing stock, and local code requirements that shape how systems perform here.

Most homeowners we work with need one of three things: a repair, a replacement, or regular maintenance. Repairs are usually quick: a burned contactor, a dirty flame sensor, a refrigerant leak, or a seized 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 itself to an early death. Tune-ups cover coil cleaning, a refrigerant charge check, safety control testing, and a static pressure reading, and nothing does more to extend the life of your system.

Commercial service makes up a large share of our work too. We service rooftop units, split systems, and ventilation equipment for restaurants, retail stores, offices, and multi-unit properties, and we know that a day without cooling costs the business. To keep disruptions short, we carry common parts on every truck, diagnose fast, and schedule larger jobs around your operating hours whenever possible.

When Your System Fails in San Francisco

Call us with a problem and a real person answers, not a phone tree. Most calls get scheduled the same day or the next, and true emergencies, a dead air conditioner during a heat wave or a furnace that fails on a freezing night, jump to the top of the schedule. Scheduling stays flexible so nobody is stuck waiting for a callback.

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 simply given up. 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.

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, shut it down at the switch and call (805) 209-1925. A few minutes of caution can prevent a much larger repair.

How San Francisco Homeowners Can Extend HVAC Life

A little routine care makes all the difference between a system that runs for years and one that quits 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 two professional tune-ups a year, so small issues get caught early.

Equipment age 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 acting up, like higher energy bills, rooms that won't reach the setpoint, or one repair after another, it's smart to start planning a replacement. A planned replacement is cheaper and causes far less stress than scrambling for a new system during the first heat wave of summer.

The sooner you call about a comfort problem, the smaller the repair tends to be. A weak capacitor is an easy, low-cost part to replace, yet that same capacitor, neglected for a season, can ruin the compressor and force a full system replacement. Save our number on your phone now so help is one call away the moment something sounds or feels wrong in your home. A quick call saves time, money, and sleepless nights.

Comfort Challenges San Francisco Homeowners Face

The service calls we run around here follow familiar patterns. In summer it's warm air from the vents, 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 thermostats misreading rooms, rising energy bills from dirty coils, and ductwork that leaks conditioned air into attics and crawlspaces. All of them start small, and all of them cost less to fix early. If your system is acting up, call (805) 209-1925 before the season turns it into an emergency.

HVAC FAQ for Local Residents

In most cases, the same day. Emergencies like a dead AC or a furnace that won't light jump ahead of scheduled tune-ups, and we'll give you an honest arrival window as soon as you call (805) 209-1925. Once our technician arrives, the common failure parts are already on board, so most problems are fixed without a second trip.
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 repair no longer makes sense, we manage the full replacement, from sizing the new equipment and removing the old unit to installation and testing in every mode. Whichever way it goes, you'll see a written quote for each option before anything happens.
It depends on two things: how old the system is and which part failed. A system under about 10 years old is usually worth repairing. Once it's past 15 years, or if the compressor or heat exchanger goes, replacement usually makes more financial sense, particularly with the efficiency improvements of new equipment. Our technicians will price both options honestly and leave the decision to you.
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 a weak part at a tune-up costs far less than a breakdown in the peak of summer, and the energy savings usually cover the cost of the visit.
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 copper lines, shut the system off so the compressor isn't damaged and call us at (805) 209-1925. We'll get a technician headed your way right away.
It depends on what's wrong. Repairs usually come in between $150 and $650, based on the failed part and the type of system. A complete system replacement generally runs about $5,000 to $12,000 installed, with size and efficiency making the difference. Before any work starts, we provide a clear quote based on the diagnostic, and that number doesn't change.
The brand name on the cabinet rarely matters. Our technicians regularly service Carrier, Trane, Lennox, Rheem, Goodman, York, and the other major names you'll find around here. On the ductless side, we service plenty of Mitsubishi, Fujitsu, and LG. Most repairs use universal parts we already carry, and brand-specific components can be sourced quickly when a repair calls for them.
Yes, and they're often the smartest answer for room additions, garages, sunrooms, and older homes that were never ducted. Every zone is sized to the room it serves. We plan where the indoor and outdoor units go and handle the line set, condensate drain, and electrical connections with care. We'll also be honest if a ducted system would serve you better.
