HVAC San Francisco, CA

Professional HVAC Service in San Francisco

For San Francisco residents, Antelope HVAC is the shortcut past every bad HVAC experience you've heard about: the vague quotes, 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 clearly, and the price is agreed before any work begins. From emergency repairs to planned upgrades, all handled by experienced pros who know the area.

Heating and Air Conditioning Service Across San Francisco

We service every type of heating and cooling equipment you'll find in local homes and businesses, from central air conditioners and gas furnaces to heat pumps and ductless mini-splits. It makes no difference whether the building is a single-family house, a condo, or a storefront. Our techs know the local climate, the age and construction of local homes, and the code requirements inspectors enforce, and that knowledge shows up in the quality of every repair.

Most homeowners we work with need one of three things: a repair, a replacement, or regular maintenance. Repairs tend to be straightforward: a burned contactor, a dirty 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.

Commercial service makes up a large share of our work too. We maintain and repair rooftop units, split systems, and ventilation equipment for restaurant kitchens, retail stores, offices, and multi-unit buildings, knowing that every hour of downtime costs the business. To keep that downtime short, we keep common commercial parts stocked, diagnose quickly, and schedule repairs around your operating hours whenever possible.

When Your System Fails in San Francisco

When your system quits, how quickly help arrives matters more than anything else. For that reason, we keep scheduling flexible across the area and put a real person on the phone. Emergency calls usually get a technician within a day, and we treat no-heat and no-cool calls as top priority.

The emergency calls we answer usually follow a pattern. On the cooling side, it's warm air from the vents, an outdoor unit that hums without starting, or an evaporator coil iced over. On the heating side, it's a furnace that ignites and drops out. Year-round, it's breakers that trip whenever the system starts, clogged condensate drains overflowing into the furnace cabinet, and thermostats that stop responding. Since our trucks are stocked with capacitors, contactors, igniters, flame sensors, universal control boards, and fittings, most of these are wrapped up in one visit, with the price agreed before any work begins.

A little caution before we arrive can prevent a much larger repair. A frozen air conditioner should be turned 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 shut the unit off at its service switch and call us right away.

Keeping Your San Francisco HVAC System Running Longer

The best way to avoid a mid-season breakdown is simple maintenance. We recommend that homeowners replace filters every one to three months, keep vegetation 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.

The age of your equipment plays a big role. With regular service, a central air conditioner typically lasts 12 to 15 years, a furnace 15 to 20, and a heat pump 10 to 15. Once a system passes that range and starts showing warning signs, like higher energy bills, rooms that won't reach the setpoint, or repeat service calls, it's time to plan a replacement. Replacing on your own schedule costs less and causes far less stress than an emergency swap during the worst heat wave of summer.

Small problems don't stay minor when they're ignored. Consider a weak capacitor: swapping it out is a short, affordable repair, but if it's ignored for a season, it can burn out the compressor, and just like that a minor fix becomes a full system replacement. That's why we ask homeowners to save our number in their phone and reach out at the first sign of trouble. Catching it early saves money and prevents a miserable night.

Typical Heating & Cooling Issues in San Francisco

Most local HVAC failures announce themselves before they happen. A breaker that trips every few days, a condenser that hums louder each month, rooms drifting further from the thermostat setting, a musty smell at startup. Those are early signs of failing capacitors, refrigerant leaks, dirty coils, and duct problems, and caught early they're an affordable repair. Ignored, they take out compressors and heat exchangers, the two most expensive parts in the system. We diagnose the cause, not just the symptom, so small problems stay small.

Why San Francisco Residents Choose Us

Plenty of companies will happily sell you a new system. Antelope HVAC earns trust around here by fixing the ones that don't need replacing and being honest about the ones that do. We find the actual fault before we quote a dollar, explain your options in plain language with real numbers, and let you decide without pressure. 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 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. That's why so much of our local work comes from repeat customers and referrals, and why we back every job with a satisfaction guarantee.
