AC Repair
AC repair cost depends on the failing part and whether the system is low on refrigerant, electrical, or mechanical. Common fixes — capacitors, contactors, fan motors, refrigerant recharges — land between $150 and $1,500 including labor, while a failed compressor runs higher.
View Nantucket pricing →Furnace Repair
Furnace repair cost depends on the failing part and whether the unit is gas or electric. Common fixes — flame sensors, igniters, blower motors, control boards — land between $150 and $1,800 including labor, while a cracked heat exchanger runs higher.
View Nantucket pricing →AC Installation
AC installation cost covers the equipment and labor to fit a new system — whether it's a like-for-like central AC replacement, a first-time install with new ductwork, or a ductless mini-split. The number swings with tonnage, SEER2 efficiency tier, and duct condition.
View Nantucket pricing →AC Maintenance
AC maintenance — a seasonal tune-up — keeps the system running efficiently and catches small faults before they become summer breakdowns. A single visit runs $75–$200; annual plans that bundle a spring AC and fall heating check cost a bit more.

HVAC cost in Nantucket.

Generic cost pages skip the things that actually decide your price and which system fits here — local code, climate, and the money you can claim back.
Recommended unit for Nantucket
Given Massachusetts’s cold climate and mixed heating, dual-fuel (cold-climate heat pump + gas furnace) is the sensible default for most Nantucket homes. A pro can confirm the right size and system for your home with a load calculation.

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.
