San Francisco HVAC Repair, Installation & Maintenance

For San Francisco residents, Clovis HVAC is the way around every bad HVAC experience you've heard about: the no-show appointment windows, the mystery invoices, the replacement pitch for a system that needed a $40 part. That's not how we work. You talk to a real person, a technician shows up on time, the diagnosis is explained in plain language, and the price is agreed before any work begins. From emergency repairs to planned upgrades, all handled by seasoned technicians who know the area.

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 understand 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 a seasonal tune-up. Repairs tend to be quick: a failed capacitor, a corroded flame sensor, a slow 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 its way to an early failure. Tune-ups include 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 attention. A hot dining room or a freezing office drives customers and staff away, 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. Property managers, restaurant owners, and retailers can ask us to work around their operating hours whenever possible.

Fast HVAC Response in San Francisco

Call us with a problem and a real person answers, not a phone tree. The majority of calls are scheduled the same day or the next, and urgent calls, an AC that quits in a heat wave or a furnace that fails on a freezing night, jump to the top of the schedule. We keep the process simple so you're not left 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 every time the system runs, 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 complete 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 common 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 continuing to run it can flood the drain pan and hurt the compressor. The second is a furnace that short-cycles or gives off a burning smell. Shut it down at the switch and give us a call. Those few minutes can save you from a far bigger repair.

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 have a professional tune-up twice a year, cooling in spring and heating in fall, so small problems get caught while they're still cheap.

Take a look at the age of your system. Its age says a lot about what comes next. With regular service, most air conditioners make it to 12 to 15 years, 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 usually due for a planned replacement, and that's almost always cheaper and easier on everyone than a rushed emergency install in peak season.

Small problems rarely stay small when they're ignored. Consider a weak capacitor: replacing it is a short, inexpensive repair, but if it's ignored for a season, it can take the compressor with it, and just like that a minor fix becomes a full system replacement. That's why we encourage homeowners to keep our number in their phone and call at the first hint of trouble. Catching it early saves money and prevents a few miserable nights.

Common HVAC Problems in San Francisco

The service calls we run around here tend to follow the calendar. In summer it's warm air from the vents, weak capacitors that finally quit on the first hot week, and iced-over evaporator coils. 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 showing symptoms, call (559) 337-5477 before the season turns it into an emergency.

Why San Francisco Homeowners Trust Us

Plenty of companies will sell you a new HVAC system. Clovis 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 for your home's genuine demand, square footage, insulation, windows, and duct capacity, instead of defaulting to whatever's on the truck.

The workmanship holds up because we don't cut corners: 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 pack up. 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.

Common Heating & Cooling Questions

Yes, and a mini-split is often the smartest answer for 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 install the line set, condensate drain, and electrical connections properly. We'll also be honest if a ducted system makes more sense for your home.
Yes, we offer seasonal maintenance for homes throughout the area. The spring visit focuses on 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. Keeping up with both visits extends equipment life, heads off breakdowns in the middle of a heat wave or cold snap, and usually pays for itself in energy savings.
Yes. We repair all major brands of air conditioners, furnaces, heat pumps, and ductless mini-splits. When a system is beyond saving, we handle the complete replacement: hauling away the old equipment, installing a properly sized new system, and testing it in every mode. You get a clear quote for each option before deciding.
Usually the same day. Emergencies like a dead AC or a furnace that won't light jump ahead of routine maintenance, and we'll tell you an honest arrival time as soon as you call (559) 337-5477. Once our technician arrives, capacitors, contactors, igniters, and motors are already on the truck, so the majority of problems get fixed during that first visit.
We service nearly every brand installed in local homes, from Carrier, Trane, and Lennox to 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.
Most repairs fall between $150 and $650 depending on the part and system type, while full system replacements usually run from around $5,000 to $12,000 installed, depending on size and efficiency. Every job starts with a diagnostic and a written, upfront quote. The price you approve is the price you pay, with no surprise line items.
First, rule out the easy stuff. Make sure the thermostat is in cooling mode and the batteries aren't dead, swap the filter if it's dirty, and look at the breakers for the indoor and outdoor units. Frost or ice on the refrigerant lines or an outdoor unit that hums but never starts is your signal to shut the system off, since continuing to run it risks damaging the compressor. Call us at (559) 337-5477 and we'll get someone moving your way right away.
It depends on two things: how old the system is and what actually broke. A system under about 10 years old is almost always worth repairing. Beyond about 15 years, or if the compressor or heat exchanger is the part that failed, replacement usually makes more financial sense, particularly with the efficiency gains of modern equipment. Our technicians will price both options honestly and leave the decision to you.
