Furnace repair cost by part.
Typical Merrillville repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Merrillville, furnace repair costs typically range from $65–$175 for a diagnostic fee, plus labor and parts. With a median home age of 48 years, many homes have older gas furnaces that may need flame sensor ($70–$225), igniter ($125–$400), or blower motor ($350–$1,350) repairs. Indiana requires a mechanical permit for furnace work, and like-for-like gas furnace replacements must bring flue/venting up to current Mechanical Code. Merrillville's mixed-humid climate with cold winters makes reliable furnace repair essential. Most homes use gas heating, and a typical system choice is an AC-gas-furnace combination.

What Merrillville code requires

- 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.
