Furnace repair cost by part.
Typical San Gabriel repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair in San Gabriel typically costs $75–$200 for a diagnostic fee, plus parts and labor. With a median home age of 70 years, many homes have aging gas furnaces that require frequent repairs. California's Title 24 mandates Manual J load calculations and HERS-verified duct leakage testing for most changeouts, which can add to overall costs. Given the mild Mediterranean climate, a heat pump is often a recommended replacement option, and the federal 25C tax credit (30%, up to $2,000) may apply for qualifying high-efficiency heat pumps.

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