Furnace Repair FAQ
Furnace repair questions
Most furnace repairs in the San Francisco Bay Area run $129–$800 — parts and labor — depending on the part. For example, hot-surface igniter typically runs $120–$350. You always get a flat-rate quote before any work begins.
Confirm the thermostat is set to heat, the breaker is on, and the filter isn't clogged. If it still won't fire, it's usually the igniter, flame sensor, or control board — we'll diagnose and repair on-site.
Once a year, ideally before winter. An annual tune-up catches worn parts early, keeps efficiency up, and protects your warranty.
A brief dusty smell at first start of the season is normal. Persistent burning, electrical, or rotten-egg odors are not — turn the system off and call us immediately.
