San Francisco HVAC Service You Can Count On

For San Francisco residents, Arcadia HVAC is the shortcut past 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. A real person answers, 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 seasoned technicians who know the area.

Complete Heating & Cooling Services for San Francisco Properties

Heating and cooling around here covers a lot of ground: older gas furnaces in established neighborhoods, 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. Our technicians have years in the field, and we know how the local climate, the age of local homes, and local code affect the way a system runs and fails.

On the residential side, we take care of everything from quick fixes, like a weak capacitor, a pitted contactor, a dirty flame sensor, or a seized blower motor, to refrigerant leak repair, complete system replacements, and ductless additions. Every new system we install is sized with a proper load calculation instead of a rule of thumb, so you get even temperatures and sensible utility bills instead of a unit that short-cycles itself to an early death. Seasonal maintenance visits clean coils, verify refrigerant charge, test safety controls, and check static pressure, the single best way to extend equipment life.

Local businesses receive the same attention. A hot dining room or a drafty office drives customers and staff away, so our commercial crews focus on getting to the cause quickly and keep common parts on board for rooftop units, split systems, and ventilation equipment. Property managers, restaurant owners, and retailers can count on us to work around their operating hours whenever possible.

When Your System Fails in San Francisco

Heating and cooling failures rarely wait for a convenient day, which is why we offer fast, flexible scheduling for most situations. When you call, you'll reach a real person who gets a technician headed to your door quickly. Arrival in the area is usually within a day for urgent calls, and a dead AC in a heat wave or a furnace out on a freezing night is the kind of call we move to the front of the line.

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, 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 situations call for a quick step from you before our technician gets there. The first is an iced-over air conditioner: switch 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 overflow the drain pan and hurt 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 much larger repair.

How San Francisco Homeowners Can Extend HVAC Life

Many mid-season breakdowns start with skipped maintenance, and the habits that prevent them are easy. Swap your filter every one to three months, clear vegetation at least two feet from the outdoor condenser, and rinse the condenser coil once a year in spring. Then book a professional tune-up each spring and fall, one for cooling and one for heating, so our technicians can catch small problems while they're still cheap to fix.

Equipment age plays a big role. With regular service, a central air conditioner usually runs 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. A planned replacement costs less and causes far less stress than an emergency swap during the worst heat wave of summer.

The sooner you call about a comfort problem, the smaller the repair tends to be. A capacitor that's starting to fail is an easy, low-cost part to replace, yet that same capacitor, 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 the moment something seems off in your home. Early intervention saves time, money, and sleepless nights.

Comfort Challenges San Francisco Homeowners Face

Ask any homeowner around here what HVAC trouble looks like and the answers sound familiar: the AC that quit during the hottest week of the year, 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: worn capacitors and contactors, low refrigerant charge, undersized returns, and years of skipped maintenance. Our technicians see these problems weekly and carry the parts to fix most of them in a single visit.

Why San Francisco Homeowners Trust Us

Choosing an HVAC company comes down to trust, and trust has to be earned. Arcadia HVAC earns it by recommending the $150 repair when that's what the system needs, by sizing replacements with real load calculations instead of guesswork, and by standing behind every repair long after the visit ends. Same-day service is available for most calls, and every visit ends with the system tested and your questions answered.

Your HVAC Questions Answered

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, place the indoor and outdoor units thoughtfully, and take care of the line set, condensate drainage, and electrical connections properly. If a ducted system serves you better, we'll say so.
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 adds years to your equipment, heads off breakdowns in the middle of a heat wave or cold snap, and usually pays for itself in lower energy bills.
First, rule out the simple causes. Confirm the thermostat is in cooling mode with good batteries, swap the filter if it's dirty, and check 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 running it can damage the compressor. Call us at (626) 231-7816 and we'll send a technician your way without delay.
In most cases, the same day. No-heat and no-cooling calls jump ahead of routine maintenance, and we'll give you an honest arrival window as soon as you call (626) 231-7816. Once our technician arrives, capacitors, contactors, igniters, and motors are already on board, so the majority of problems get fixed during that first visit.
Most repairs fall between $150 and $650 depending on the part and system type, while full system replacements typically 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 surprises added later.
We do both. Most visits begin as a repair, and our technicians work on air conditioners, furnaces, heat pumps, and ductless mini-splits from all the major manufacturers. When a system can't be saved, we manage the full replacement, from the load calculation and hauling off the old unit to installation and testing in every mode. Whichever way it goes, you'll see a written quote for both options before you decide.
The brand name on the cabinet rarely matters. Our team work on Carrier, Trane, Lennox, Rheem, Goodman, York, and the other major names you'll find around here. For ductless systems, we see plenty of Mitsubishi, Fujitsu, and LG. Most repairs use universal parts that ride on the truck, and brand-specific components are quick to source when a repair calls for them.
There's no single cutoff, but a few rules of thumb help. Most component failures on systems under about 10 years old are worth repairing. Past the 15-year mark, or after a compressor or heat exchanger failure at any age, replacing the system usually makes better financial sense, and newer equipment brings real efficiency gains. We'll show you both numbers honestly and let you decide, because we'd rather earn your trust than sell you a system early.
