Furnace Repair — Bay Area

Common Furnace Problems We Repair

• Furnace won't turn on — no ignition or no heat output
• Pilot light or igniter failure (intermittent or persistent)
• Cracked heat exchanger — a carbon monoxide safety hazard
• Faulty flame sensor causing repeated shutdowns
• Blower motor not running or running constantly
• Draft inducer motor failure
• Control board or sequencer failure (electric furnaces)
• Gas valve issues or no gas flow to burners
• Dirty or clogged burners causing yellow or uneven flame
• Pressure switch or limit switch faults
• Short cycling — furnace turns on and off repeatedly

What Our Furnace Repair Includes

We start with a full safety inspection before any repair — combustion analysis, heat exchanger integrity check, flue and venting inspection, and gas pressure measurement. You get a clear diagnosis and written quote before work begins.

• Full diagnostic including safety checks and combustion test
• Heat exchanger inspection for cracks or deterioration
• Igniter, flame sensor, and ignition control testing
• Gas valve, manifold pressure, and burner inspection
• Blower and inducer motor testing
• Control board diagnosis and programming
• Flue and vent inspection for blockages or backdrafting
• CO testing and safety verification

Repair or Replace — What Makes Sense

A cracked heat exchanger is almost always a replace situation — it's a carbon monoxide hazard and the repair cost approaches a new furnace. For most other repairs, if the furnace is under 15 years old and otherwise in good condition, repair makes sense. We'll walk you through both options with honest numbers.
