Furnace repair cost by part.
Typical Lafayette repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair in Lafayette, Indiana, typically costs between $75 and $3,200 depending on the part and labor. With a median home age of 57 years, many furnaces are older and may require repairs to components like flame sensors, igniters, or blower motors. The local climate is mixed-humid with cold winters, making a reliable furnace essential. Indiana requires a mechanical permit for furnace work, and gas-furnace changeouts must bring flue and venting up to current code, even for like-for-like swaps. Most homes use gas heating, and a gas furnace paired with an AC is a common system choice.

- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRequired (Manual J)

- Good to know—
Indiana Residential Code (2018 IRC base) requires HVAC equipment to be sized per ACCA Manual J/S, and gas-furnace changeouts must bring flue/venting up to current Mechanical Code even on like-for-like swaps.

Common furnace problems in Lafayette
Flame sensor failure
A dirty or faulty flame sensor causes the furnace to cycle on and off. This is common in older Lafayette homes.
Igniter malfunction
A cracked or worn igniter prevents the furnace from lighting. Frequent in systems over 10 years old.
Blower motor issues
A failing blower motor reduces airflow, leading to uneven heating. Often due to age or lack of maintenance.
What to expect during a furnace repair in Lafayette
A technician will first diagnose the issue, charging a $70–$175 diagnostic fee. They will check the furnace, identify the faulty part, and provide a cost estimate. Repairs require a mechanical permit from the local building department. For gas furnaces, the technician must ensure flue and venting meet current Indiana Mechanical Code. Most repairs are completed in one visit, but heat exchanger replacements may take longer.
