Furnace repair cost by part.
Typical Westmont repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Westmont, California, furnace repair costs reflect the area's older homes (median built 1955) and local code requirements. Typical diagnostic fees run $65–$175, with common repairs like flame sensor replacement ($65–$200) or igniter replacement ($125–$375). Because most homes use gas heating and have aging systems, repairs often involve blower motors ($325–$1,250) or control boards ($250–$650). California's Title 24 mandates Manual J load calculations and HERS-verified duct leakage testing for most furnace changeouts, which can add to project costs. Given the mild Mediterranean climate, a heat pump may be a well-suited replacement option, and the federal 25C tax credit (30%, up to $2,000 for a qualifying heat pump) can offset upgrade costs.
