Furnace repair cost by part.
Typical Montclair repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Montclair, CA, furnace repair costs typically range from $75 for a simple flame sensor replacement to over $3,300 for a heat exchanger, plus a $70–$175 diagnostic fee. With a median home age of 57 years, many systems are older and may need more frequent repairs. California's Title 24 requires permits and HERS-verified duct leakage testing for most replacements, and Manual J load calculations are mandatory. Given the mild Mediterranean climate and moderate cooling demand, a heat pump is often a recommended system choice, eligible for the federal 25C tax credit (30%, up to $2,000).

What affects furnace repair costs in Montclair?
Repair costs vary by the part needing replacement—flame sensors ($75–$225) are more affordable than blower motors ($375–$1,400) or heat exchangers ($1,400–$3,300+). Labor rates reflect local HVAC technician costs, and the age of your system (median home built 1969) may mean harder-to-find parts. Permit fees and required Manual J load calculations add to the total. The federal tax credit can offset costs if you upgrade to a qualifying heat pump.
