Furnace repair cost by part.
Typical West Lafayette repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In West Lafayette, furnace repair costs reflect the area's mix of older homes and rental properties. With a median home age of 37 years, many furnaces are nearing or past their expected lifespan. Typical repair prices range from $65 for a flame sensor to over $2,900 for a heat exchanger, plus a $60–$175 diagnostic fee. Indiana requires a mechanical permit for most repairs, and the 2018 IRC-based code mandates that gas furnace replacements bring flue and venting up to current standards—even for like-for-like swaps. Given the cold winters and moderate cooling demand, a gas furnace with central AC is the recommended system. The federal 25C tax credit (up to $600 for high-efficiency AC) is available here.

What West Lafayette code requires
Installing or replacing an HVAC system in West Lafayette follows Indiana rules under the state mechanical code. Here’s what applies statewide:
- PermitRequired
Mechanical permit pulled by your licensed HVAC contractor; covers equipment, refrigerant, and the electrical disconnect.
- 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)
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—
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.
