Furnace Repair, done honestly in Sebastopol.

A dead furnace on a cold night doesn't wait for business hours, and in Sebastopol — where fog-belt cool summers and damp winters — heating failures are safety issues as much as comfort ones. We repair all major furnace brands, and every repair visit includes verifying the safety controls and checking carbon monoxide in the living space with proper test instruments.

Across older farmhouses and 70s-era homes, the furnace problems we see most are failed ignitors and flame sensors, cracked or corroded components in older heat exchangers, tired blower motors, and short-cycling from clogged filters or failing limit switches. Because damp shade is hard on heat exchangers and venting, we look beyond the immediate fault to what caused it.

You get the diagnosis and the repair price in writing before we touch a wrench. If the honest answer is that your furnace is near the end, we tell you that too — including what California's 2027 rules mean for your replacement options.

Heat is a safety system, not just a comfort one, so a Sebastopol furnace repair is never only about getting warm air moving again. We verify the burner, the safety controls, and carbon monoxide in the living space with real instruments before we consider the job done. Because damp shade is hard on heat exchangers and venting, we also look at what caused the failure — a clogged filter, a failing motor, a venting issue — so the same problem doesn't put you back in the cold next month.
