Full-Service HVAC Care for San Francisco Homes and Businesses

Heating and cooling around here covers a lot of ground: aging furnaces in established neighborhoods, newer heat pumps in recent construction, ductless mini-splits in additions and converted garages, and rooftop units on commercial buildings. Our team works on every one of those systems. We have years of field experience, and we know how the weather here, the age of local homes, and local code affect the way a system runs and fails.

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 corroded flame sensor, a refrigerant leak, or a worn-out blower motor. When we replace a system, it gets 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. Maintenance visits cover coil cleaning, a refrigerant charge check, safety control testing, and a static pressure reading, and nothing does more to extend equipment life.

Commercial service is a big part of what we do too. We service rooftop units, split systems, and ventilation equipment for restaurants, retail stores, offices, and multi-unit buildings, and we know that every hour of downtime hurts your bottom line. To keep disruptions short, we keep common commercial parts stocked, diagnose quickly, and schedule repairs around your operating hours whenever possible.

Quick Heating and Cooling Help in San Francisco

Call us with a problem and a real person picks up, not a phone tree. Most calls are scheduled within a day, and true emergencies, a dead air conditioner during a heat wave or a furnace that goes out on a bitter night, jump to the top of the schedule. We keep the process simple so you're not 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 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.

Two situations call for a quick step 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 damage the compressor. The second is a furnace that keeps cycling on and off or gives off a burning smell. Turn it off at the service switch and give us a call. Those few minutes can save you from a far bigger repair.

How San Francisco Homeowners Can Extend HVAC Life

The best way to avoid a mid-season breakdown is routine maintenance. We recommend that homeowners replace filters every one to three months, keep shrubs and grass 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. Its age tells you a lot. With regular service, most air conditioners make it to 12 to 15 years, gas furnaces 15 to 20, and heat pumps 10 to 15. If your system is past that range and also shows rising bills, rooms that never quite reach temperature, or frequent repairs, it's a strong candidate for a planned replacement, and that's almost always cheaper and easier on everyone than a rushed emergency install in peak season.

The earlier you report a comfort problem, the cheaper it usually is. A capacitor that's starting to fail is an easy, low-cost part to replace, yet the same part, ignored through a full season, can take out the compressor and turn a simple fix into a full system replacement. Save our number in your contacts today so help is one call away as soon as something sounds or feels wrong in your home. A quick call saves time, money, and miserable nights.

Comfort Challenges San Francisco Homeowners Face

Ask any homeowner around here what HVAC trouble looks like and you'll hear the same stories: the AC that quit during the hottest week of the year, the furnace that woke everyone up with a loud bang at 2am, the system that runs all day but never satisfies the thermostat. Behind those stories are predictable culprits: failing blower motors, low refrigerant charge, crushed or leaky ducts, and years of skipped maintenance. Our technicians run into these problems every week and carry the parts to fix most of them on the first trip.

HVAC FAQ for Local Residents

First, rule out the simple causes. Confirm the thermostat is in cooling mode with good batteries, replace the filter if it's dirty, and check 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 running it risks damaging the compressor. Call us at (530) 201-3647 and we'll send a technician your way without delay.
Yes, and for most homeowners it's the smartest money you can spend on a system. Each spring and fall, 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 during a tune-up costs far less 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 some guidelines help. Most component failures on systems under about 10 years old are worth the repair. Past the 15-year mark, or after a compressor or heat exchanger failure at any age, replacing the system usually comes out ahead, and newer equipment brings real efficiency gains. We'll give you both numbers up front and let you decide, because we'd rather earn your trust than sell you a system early.
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 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 clear pricing for each option before you decide.
Most calls are scheduled the same day, and an emergency with no heat or no AC moves to the top of our list. When you reach us at (530) 201-3647, you'll get a straight arrival window, and since the technician shows up with capacitors, contactors, igniters, and motors already on board, the job usually wraps up in one trip.
It depends on the job. Most repairs come in between $150 and $650, depending on the part that failed and the type of system. A full replacement generally runs around $5,000 to $12,000 installed, depending on size and efficiency rating. Before any work starts, you'll get a clear quote based on the diagnostic, and that number doesn't change.
Yes. Mini-splits are a great fit for additions, garages, sunrooms, and older homes that never had ductwork. We size each zone to the room it serves, position the indoor and outdoor units carefully, and take care of the line set, condensate drainage, and electrical connections correctly. If central equipment serves you better, we'll say so.
Every major brand, such as 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 order brand-specific components quickly when a repair requires them.
