What Homeowners Call Us For

The Two Repairs We Get Called For Most

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

A dead air conditioner on a hot afternoon is the call we run most. The usual culprit is a small electrical part, a capacitor or contactor, that our trucks carry, so most AC repairs are finished in one visit. 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
  • Outdoor unit humming but not starting
  • Ice on the refrigerant lines or indoor coil
  • Water leaking near the indoor unit
AC repair pricing and details

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.

  • Furnace clicks but never lights
  • Burners light, then shut off within seconds
  • Cold air from the vents in heating mode
  • New noises when the furnace kicks on

HVAC Problems We Solve

Common Heating & Cooling Problems in San Francisco

Wondering if it's bad enough to call? These are the most common heating and cooling problems we handle in homes across the area.

AC Blowing Warm Air

A system pushing warm air in summer is the call we run most. Our trucks carry capacitors, contactors, and motors to restore cooling same-day.

AC repair

Furnace Won't Stay On

Short cycling wastes gas, stresses the heat exchanger, and never quite warms the house. We find the safety control tripping it and fix the cause.

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

We size replacements with a real load calculation, not a guess, so the new system delivers even temperatures and lower bills from day one.

System replacement

Dusty Air & Musty Smells

Dust settling everywhere within a day of cleaning, musty odors when the system kicks on, or allergy flare-ups indoors all point to the ductwork.

Air duct cleaning

Rooms That Never Get Comfortable

We size and mount mini-splits cleanly, proper line sets, condensate handling, and a tidy exterior finish, so they work as good as they look.

No Upsell, Ever

We treat your budget like our own: fix what's fixable, replace what isn't, and size every new system to your home instead of the biggest thing on the truck.

"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. We had heat again by mid-morning. Absolute pros."

"Years of dust, pet hair, and who knows what else came out of our ducts. After the cleaning, rooms that never got air finally do, and my wife's morning allergies have calmed way down. They showed us before-and-after photos of everything they pulled out."

"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. Our winter bills dropped noticeably the first season, and we got cooling out of the same equipment. Zero regrets on this one."

HVAC Questions

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.

Don't Wait for the Weather to Win.

Waiting only makes a failing system worse and the house less livable. Call now and our experienced team can respond fast with upfront pricing.
