San Francisco HVAC Repair, Installation & Maintenance
Comfort in San Francisco shouldn't depend on the season. Florin HVAC keeps local homes and businesses comfortable year-round with fast, professional heating and cooling service, from quick furnace repairs to properly sized new systems. We've worked in nearly every neighborhood in the area, which means we've seen how these systems fail locally and we arrive prepared, with the common failure parts already on board. One call to (279) 236-7613 and the problem starts getting solved.

Full-Service HVAC Care for San Francisco Homes and Businesses
Heating and cooling around here means a wide mix of equipment: older gas furnaces on the older streets, newer heat pumps in recent construction, ductless mini-splits in additions and converted garages, and packaged units on commercial buildings. Our team handles all of it. We have years of field experience, and we've learned how the weather here, the age of local homes, and local code affect the way a system runs and fails.
Most homeowners we work with need one of three things: a repair, a replacement, or regular maintenance. Repairs tend to be straightforward: a failed capacitor, 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 its way to an early failure. Maintenance visits include 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.
For commercial property owners and managers nearby, we service the rooftop units, split systems, and dedicated ventilation equipment that restaurants, shops, offices, and apartment buildings depend on. We understand that a hot dining room or a freezing office means lost business, so we prioritize fast diagnosis, stock common parts on the truck, and schedule work around your operating hours whenever possible.
Fast HVAC Response in San Francisco
Call us with a problem and a real person answers, not a recording. The majority of calls are 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 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, iced-over 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. We provide upfront pricing every time, so you know exactly what the work will cost before we begin.
Two common situations call for quick action 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 the moving air thaws the coil, because continuing to run it can flood the drain pan and damage the compressor. The second is a furnace that keeps cycling on and off or produces a burning smell. Turn it off at the service switch and call us. Those few minutes can save you from a far bigger repair.
How San Francisco Homeowners Can Extend HVAC Life
Routine maintenance makes all the difference between a system that lasts and one that breaks down in the middle of a heat wave. Our advice for homeowners is a short list: a new filter every one to three months, at least two feet of open space around the outdoor condenser, a spring rinse of the condenser coil, and a professional tune-up every spring and fall, so problems are found 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 reach 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, uneven temperatures, or repeated repairs, it's usually due for a planned replacement, which is almost always cheaper and less stressful than a rushed emergency install in peak season.
Small problems don't stay minor for long. Take a weak capacitor: swapping it out is a quick, inexpensive repair, but left alone for a season, it can burn out the compressor, and suddenly a minor fix has become a full system replacement. That's why we encourage homeowners to keep our number in their phone and reach out at the first hint of trouble. Catching it early saves money and spares you a miserable night.
Common HVAC Problems in San Francisco
Ask any homeowner around here what HVAC trouble looks like and you'll hear the same stories: the upstairs that never cools, the furnace that woke everyone up banging 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 in a single visit.
