Furnace repair cost by part.
Typical Petaluma repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair in Petaluma, California, typically costs between $85 and $225 for a diagnostic visit, plus parts and labor. With a median home age of 47 years, many homes have older furnaces that may need repairs like flame sensor cleaning ($90–$275) or igniter replacement ($175–$500). Petaluma's mild Mediterranean climate means furnaces are used less intensively than in colder regions, but the hot-dry summers still require reliable heating for cooler nights. California's Title 24 energy code mandates Manual J load calculations and HERS-verified duct leakage testing for most furnace changeouts, which can add to the cost. For many Petaluma homeowners, a heat pump may be a more efficient choice, especially with the federal 25C tax credit covering 30% of qualifying heat pump costs up to $2,000.

- Good to know—
CA Title 24 requires HERS-verified duct leakage testing and Manual J sizing on most AC/furnace changeouts
