Heating and Air Conditioning Service Across San Francisco

Whether you own a condo, a rental property, or a commercial space in town, we have the know-how and equipment to handle the full range of heating and cooling work. Our technicians have spent years working on central air conditioners, gas and electric furnaces, heat pumps, and ductless mini-splits throughout the area, and we pay close attention to the climate patterns, housing stock, and local code requirements that shape how systems perform in this area.

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 slow 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, which does more than anything else to extend the life of your system.

Local businesses receive the same care. An overheated storefront or a freezing office costs real money, so our commercial technicians focus on getting to the cause quickly and keep high-failure parts on board for rooftop units, split systems, and ventilation equipment. Restaurants, retail shops, offices, and multi-unit buildings can ask us to work around their business hours whenever possible.

When Your System Fails in San Francisco

Call us with a problem and a real person answers, not a recording. Most service requests get scheduled within a day, 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 you're not stuck waiting for a callback.

These are the problems that come up most when something breaks at home: an air conditioner blowing warm air, a condenser that hums but won't start, a furnace that ignites and shuts off, a breaker that trips every time the system kicks on, an evaporator coil that has frozen, a condensate drain backed up into the furnace cabinet, or a thermostat that has quit. Most of them trace back to a part we already carry: capacitors, contactors, igniters, flame sensors, universal control boards, and standard fittings. You get the price before any work starts, with no surprises on the invoice.

A little caution before we arrive can head off a much bigger repair. An iced-over AC should be shut off at the thermostat with the fan set to "on", which lets the coil thaw faster. Running it frozen can flood the drain pan and damage the compressor. A furnace that keeps short-cycling, or any burning smell, means it's time to kill power at the furnace switch and call us right away.

Getting More Years From Your HVAC System in San Francisco

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 schedule 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 says a lot about what comes next. Most well-maintained air conditioners make it to 12 to 15 years, gas furnaces 15 to 20, and heat pumps 10 to 15. If your system is beyond that range and also shows rising bills, rooms that never quite reach temperature, or repeated repairs, it's usually due for a planned replacement, and that's almost always cheaper and less stressful than a rushed emergency install in peak season.

The sooner you call about a comfort problem, the smaller the repair tends to be. A capacitor that's starting to fail costs little to replace, yet the same part, neglected for a season, can take out the compressor and turn a simple fix into a full system replacement. Save our number on your phone today so help is one call away the moment something sounds or feels wrong in your home. Early intervention saves time, money, and sleepless nights.

Common HVAC Problems in San Francisco

The service calls we run around here tend to follow the calendar. In summer it's air conditioners humming but not cooling, 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 clogged filters choking airflow, 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 (279) 236-7586 before the season turns it into an emergency.

Why San Francisco Residents Choose Us

Plenty of companies will happily sell you a new system. Folsom HVAC earns trust around here by fixing the ones that don't need replacing and being straight about the ones that do. Our technicians diagnose the actual fault before quoting anything, explain your options in plain terms with real numbers, and leave the decision to you. When replacement is the right call, we size the new system with a proper load calculation based on your home's real heating and cooling load, square footage, insulation, windows, and duct capacity, instead of defaulting to whatever's on the truck.

The workmanship holds up because we sweat the details: correct refrigerant charge weighed in rather than guessed, sealed duct connections, proper condensate drainage, verified combustion and airflow on heating equipment, and clean electrical work that passes inspection the first time. We show up when we said we would, cover your floors, haul away the old equipment, and test the full system in every mode before we leave. It's why so much of our local work comes from repeat customers and referrals, and why we back every job with a satisfaction guarantee.

HVAC FAQ for Local Residents

For a lot of homes, yes. Ductless systems shine in additions, converted garages, sunrooms, and older homes that never had ducts. Our approach starts with sizing each zone for the real load of that room, then thoughtful placement of the indoor and outdoor units and a proper install of the line set, condensate drainage, and electrical connections. If central equipment is the better choice for your home, we'll tell you.
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 (279) 236-7586, you'll get a straight arrival window, and since the technician shows up with capacitors, contactors, igniters, and motors already on board, most repairs wrap up in one 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 a system can't be saved, we take care of the whole replacement, from the load calculation 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.
We always quote before we start, so you know the price up front. As a general range, most repairs cost $150 to $650 depending on the part and system, and complete new systems cost roughly $5,000 to $12,000 installed based on size and efficiency. Your exact price comes from a diagnostic visit at your home, and the price you approve is the price you pay, no surprises added later.
We service just about everything installed in local homes, including Carrier, Trane, Lennox, 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 can source it quickly.
It comes down to age and which part failed. 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 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 before you need one.
We do offer twice-a-year maintenance across the area. The spring visit covers cooling: cleaning the coils, verifying the refrigerant charge, testing the capacitor, and measuring airflow. The fall visit covers heating: cleaning the burners, checking combustion, and testing every safety control. Staying on that schedule extends equipment life, heads off breakdowns in the middle of a heat wave or cold snap, and often pays for itself in lower energy bills.
Check the thermostat setting 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 (279) 236-7586. We'll get a technician headed your way right away.
