AC Repair & Furnace Repair in Berkeley

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 Berkeley

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
  • Condenser fan not spinning
  • Ice on the refrigerant lines or indoor coil
  • Condensate backing up around the air handler
AC repair costs and common fixes

Furnace Repair in Berkeley

When the furnace clicks but never lights, lights and shuts off, or runs without warming the house, the cause is usually one component. We test the ignition, airflow, and safety controls to find it. You'll get a clear quote first, plus a safety check of the combustion and venting while we're there.

  • No ignition when the heat calls
  • 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

Recognize These HVAC Warning Signs?

HVAC trouble shows up in many ways. If you're dealing with any of these problems, don't wait to call for prompt help.

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

A system that runs constantly but never satisfies the thermostat is burning money. Seasonal maintenance restores the efficiency you paid for.

Maintenance & tune-ups

Old System, Repeat Repairs

A system past 12 to 15 years that needs a repair every season is telling you something. We'll give you the honest math on repair versus replacement.

System replacement

Dusty Air & Musty Smells

A musty smell at startup often means moisture in the ducts or a dirty evaporator coil, worth addressing before it becomes a bigger air-quality problem.

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.

There's no mystery to how we handle an urgent failure. Here's the step-by-step of what we do after a homeowner calls for fast help.

The call

Your Call, Our Priority

You call (510) 201-4758. A real person picks up, assesses your situation, and books the soonest available technician.

Right away

Your technician shows up ready to work, not just to look. The common failure parts ride on every truck, so the visit moves straight from diagnosis into repair.

The visit

Ongoing

Follow-Up and Prevention

Lasting comfort is the whole point. We verify the repair, note the system's age and condition, and offer a simple seasonal plan that keeps efficiency up, breakdowns down, and miserable nights off your calendar.

What Berkeley Homeowners Say

★★★★★
4.8 out of 5 · 150 reviews

"Another company quoted us a full system replacement. Berkeley HVAC traced it to a failed blower motor and fixed it for a fraction of that quote. The tech said the rest of the system had years left in it. That kind of honesty is rare."

Berkeley, CA

"From the estimate to the final walkthrough, the whole install was clear and professional. The crew wore shoe covers, put down drop cloths, hauled off the old equipment, and the final bill matched the quote exactly. The new system is so quiet we barely notice it running. I'd send anyone in Berkeley their way."

JL
Joan L.
Berkeley, CA

"Half our house was always five degrees warmer than the thermostat said. The tech found crushed flex duct and a dampener stuck half-closed, then set up a new smart thermostat and actually taught us how to use it. Every room finally feels the same."

Quick Answers

HVAC Questions

Most air conditioner repairs in Berkeley 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 Berkeley 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 Berkeley 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.
