AC Repair & Furnace Repair in San Francisco

Two systems do most of the work in a typical home, and they're the two we repair most. Here's what to expect when you call.

AC Repair in San Francisco

Most air conditioner breakdowns trace back to one failed part: a weak capacitor, a burned contactor, a seized fan motor, or a slow refrigerant leak. We diagnose it with gauges and meters, not guesswork. You get a clear price before any work starts, and if the system is old enough that replacement makes more sense, we'll show you both numbers.

  • AC running but blowing warm air
  • Condenser fan not spinning
  • Frozen coil or iced-over lines
  • Condensate backing up around the air handler
AC repair costs and common fixes

Furnace Repair in San Francisco

A furnace that won't light on a cold night can't wait until morning. Most no-heat calls come down to a dirty flame sensor, a failed igniter, or a blower motor, and our trucks carry the common parts to fix them on the spot. Every visit includes a safety check of the burners and venting, and you'll know the price before we start.

  • No ignition when the heat calls
  • Burners light, then shut off within seconds
  • Blower running but the air isn't warm
  • Loud banging, squealing, or grinding at startup

When to Call

When Homeowners Should Call for Help

Not sure if you need professional help? These are the most common heating and cooling problems we fix in homes across the area.

AC Blowing Warm Air

Warm air from the vents usually traces to a weak capacitor, a refrigerant leak, or a frozen coil, all fixable, and all diagnosable in one visit.

AC repair

Furnace Won't Stay On

If the blower runs but the air never warms, or the unit clicks without lighting, the failure is diagnosable in minutes with the right tools.

Furnace repair

Rising Bills, Weak Airflow

Weak airflow at the vents points to duct restrictions, a struggling blower, or high static pressure. A tune-up finds it before it kills the motor.

Maintenance & tune-ups

Old System, Repeat Repairs

When repair bills start stacking up, a modern high-efficiency system often costs less per month than keeping the old one alive.

System replacement

Dusty Air & Musty Smells

If some rooms get dusty faster than others, leaky or dirty duct runs are the likely cause. We inspect, clean, and seal what we find.

Air duct cleaning

Rooms That Never Get Comfortable

A garage office, a converted attic, or that one bedroom the ducts never reached, a ductless mini-split solves it without tearing open walls.

★★★★★
Rated 4.8/5 · 150 reviews

"The furnace quit at 11 pm with the temperature dropping fast and a newborn in the house. They answered right away and talked me through checking the thermostat and breaker, then had a technician out first thing. Heat was back before noon. Absolute pros."

"Years of dust, pet hair, and who knows what else came out of our ducts. After the cleaning, the airflow from every vent is noticeably stronger, and my wife's morning allergies have calmed way down. They showed us before-and-after photos of everything they pulled out."

GW
Greg W.
San Francisco, CA

"When our old furnace was on its last legs, they walked us through converting to a heat pump instead of just quoting a like-for-like swap. The first winter's bills were noticeably lower, and we got cooling out of the same equipment. Zero regrets on this one."

Our Commitment to San Francisco Homeowners

We do more than patch the symptom. We make sure the job is done right. Every visit is backed by our experience, honest recommendations, and thorough work you can count on.

Maintenance That Pays for Itself

Our team focuses on keeping systems alive with simple, scheduled care. If you want years more from your current equipment, our seasonal tune-up plans handle the checks that actually extend equipment life. No surprises, no hidden fees. This focus on longevity is why so many homeowners recommend us.

Quick Answers

Your Questions, Answered

Most air conditioner repairs in San Francisco run between $150 and $650, depending on the part. Common fixes like capacitors, contactors, and fan motors sit at the lower end, while compressor and refrigerant work costs more. If the system is beyond economical repair, full replacement typically ranges from $5,000 to $12,000 installed depending on size and efficiency. We diagnose first and give you a clear, upfront quote before any work begins.
A good rule of thumb: if the system is under 10 years old and the fix is a component, capacitor, motor, igniter, sensor, repair usually makes sense. If the compressor or heat exchanger has failed, the unit is past 12 to 15 years old, or repairs are stacking up season after season, replacement is the smarter investment. Our technicians walk you through both numbers honestly so you can decide with real information.
We offer same-day and emergency HVAC service throughout the San Francisco area. Our trucks carry the most common parts, capacitors, contactors, igniters, flame sensors, and universal motors, so the majority of repairs are completed in a single visit. Even full system replacements are usually scheduled within days, not weeks.
For many San Francisco homes, yes. Modern heat pumps heat and cool from a single system, run far more efficiently than electric resistance heat, and current models perform well even in cold weather. They cost more upfront than a basic AC swap, which is why we run the numbers on your actual usage and utility rates before recommending one.
Yes. Our technicians work on all major residential and commercial brands and system types, central air conditioners, gas and electric furnaces, heat pumps, packaged units, and ductless mini-splits. We carry universal parts on the truck and can source brand-specific components quickly when needed.
