Winter Dispatch Ready

Furnace Repair in Greenbrae, CA

A furnace that won't ignite, short-cycles, or trips its limit switch repeatedly needs more than a reset — it needs a technician checking the ignitor, flame sensor, and heat exchanger. Every Furnace Repair visit includes a carbon monoxide safety check before we leave, not an upsell.

Combustion Analysis on Every Call Gas & Electric Furnace Techs Same-Day Winter Response

A short list of components causes the overwhelming majority of Furnace Repair calls: the ignitor, the flame sensor, the gas valve, or the heat exchanger. We test each with a multimeter and combustion analyzer rather than replacing parts on a hunch.

What Makes Our Furnace Techs Different in Greenbrae, CA

Safety and accuracy on every heating call.

CO Testing on Every Visit

A CO safety check with a combustion analyzer is part of every visit, not an optional add-on.

Same-Day Winter Dispatch

No-heat calls during cold snaps get priority routing over routine maintenance stops when temperatures drop, especially in peak winter.

Quoted Before Repairs Start

You approve a fixed repair price before any part is replaced, whether it's an ignitor or a heat exchanger.

Trained on Both Fuel Types

Whether the furnace runs on gas or electric heat strips, our techs are trained on both, so the fuel type never determines who gets sent.

What Our Furnace Techs Actually Fix

The most common furnace failure points.

Ignitor & Flame Sensor Service

Cracked ignitors and carbon-fouled flame sensors account for a large share of no-heat calls, and both are usually same-visit fixes.

Gas Valve Diagnostics

Gas valve testing means checking actual response and pressure output, since these parts are costly enough to warrant confirming the fault first.

Heat Exchanger Inspection

Because a cracked heat exchanger can leak combustion byproducts into the home's air, we inspect it carefully with a scope and analyzer rather than assuming based on age alone.

Limit Switch & Blower Motor Repair

A furnace that short-cycles or shuts down mid-cycle often points to a tripped limit switch or failing blower — we test both before condemning the control board.

Pilot Light & Standing Pilot Repair

We still service standing-pilot furnaces, checking thermocouple output and draft conditions that newer ignition systems don't have.

Thermostat & Wiring Diagnostics

A furnace that won't respond at all to the thermostat is sometimes a wiring or control issue, not a furnace failure — we rule this out early to avoid overcharging for parts you don't need.

Greenbrae Furnace Repair Reviews

Recent reviews from winter heating calls.

★★★★★

Furnace kept shutting off every twenty minutes. Their technician found a dirty flame sensor and cleaned it, been running fine for two months now.

— B. Halloran, homeowner

★★★★★

They caught a hairline crack in the heat exchanger during a routine repair call and walked me through the safety concern honestly, not to upsell.

— V. Ashworth, homeowner

★★★★★

No heat during the coldest week of the year, they got someone out same day and had it fixed within an hour, ignitor replacement.

— Q. Delrio, homeowner

★★★★★

Old standing pilot furnace that most companies don't want to touch anymore. They knew exactly what they were doing, thermocouple was the issue.

Frequently Asked Questions

Common questions before a Furnace Repair visit.

A furnace that clicks or hums but never lights is a strong sign of an ignitor issue, but we confirm with a resistance test before quoting.

Yes — it can allow combustion gases to mix with breathing air, which is why we test carefully and won't run the furnace if confirmed cracked, so we take the inspection seriously and won't operate a confirmed-cracked unit.

Every furnace call includes a CO check with a combustion analyzer, no extra charge.

Yes — our techs are trained on thermocouples, pilot orifices, and draft diagnostics for older systems, including thermocouple and draft-related repairs.

No-heat calls get priority routing, typically same-day during winter demand even during high-demand cold weather.

Common failure parts ride on the truck already; something unusual might mean a next-day return visit to complete the repair.
