Furnace repair cost by part.
Typical Santa Rosa repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Santa Rosa, furnace repair costs typically range from $90–$250 for a diagnostic visit, plus labor and parts. Common repairs include flame sensor replacement ($100–$300), igniter replacement ($175–$550), blower motor replacement ($500–$1,850), control board replacement ($375–$1,000), and heat exchanger replacement ($1,850–$4,300+). Because most homes were built around 1980, older furnaces may need more extensive repairs. California's Title 24 requires a Manual J load calculation and HERS-verified duct leakage testing for most furnace changeouts, and a mechanical permit is needed for any repair involving gas or electrical work. Given Santa Rosa's mild Mediterranean climate, a heat pump is often a well-suited upgrade, but gas furnaces remain common for heating.
