Furnace repair cost by part.
Typical Belmont repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Belmont, furnace repair costs are shaped by the city's older housing stock (median home built 1967) and California's strict energy codes. Typical diagnostic fees run $75–$200, with common repairs like flame sensor replacement ($80–$250) or igniter repair ($150–$450). Because most homes use gas heating, repairs often involve gas components and must comply with Title 24, which requires Manual J load calculations and HERS-verified duct leakage testing for any system changeout. Permits are mandatory for most repairs, adding to the overall cost. Given Belmont's mild Mediterranean climate, a heat pump is recommended for efficiency, but furnace repairs remain common for existing gas systems.

Federal Southwest-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRequired (Manual J)
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
CA Title 24 requires HERS-verified duct leakage testing and Manual J sizing on most AC/furnace changeouts
