Furnace repair cost by part.
Typical Nantucket repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
Furnace repair in Nantucket, Massachusetts, typically involves diagnostic fees of $70–$175 and part-specific labor. Common repairs include flame sensors ($75–$225), igniters ($150–$425), blower motors ($375–$1,400), control boards ($275–$750), and heat exchangers ($1,400–$3,300+). Nantucket's cold climate (Zone 5) and older homes (median built 1982) mean furnaces work hard, and repairs often require permits per Massachusetts code. Many homeowners consider dual-fuel systems for efficiency, especially with Mass Save rebates shifting to cold-climate heat pumps after 2025.

What Nantucket code requires
Installing or replacing an HVAC system in Nantucket follows Massachusetts 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 calculationRecommended
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—
Cold-climate (Climate Zone 5) sizing matters; Mass Save now requires cold-climate-rated heat pumps and excludes R-410A models from rebates as of Jan 1, 2026.
