Furnace repair cost by part.
Typical Iselin repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Iselin, New Jersey, furnace repair costs are shaped by the age of the home (median built 1960), local labor rates, and strict code requirements. With a median household income of $109,646, homeowners typically face diagnostic fees of $70–$175 and part-specific pricing: flame sensor $75–$225, igniter $150–$425, blower motor $375–$1,400, control board $275–$750, and heat exchanger $1,400–$3,300+. The mixed-humid climate with cold winters makes reliable furnace operation critical, and most homes use gas heating. New Jersey's Uniform Construction Code (NJAC 5:23) mandates a mechanical permit and inspection for any furnace repair involving replacement of major components, adding $50–$150 to the total. For a like-for-like changeout, a permit is still required. Choosing a system like an AC-gas furnace combination is recommended for efficiency and comfort.
