AC installation cost by system.
Installed pricing for Madison, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Madison, NJ, where the median home was built in 1958, many homeowners face AC replacements for aging systems. Typical installed costs for a like-for-like central AC range from $3,700 to $7,500, while a new system with ductwork runs $5,600 to $12,200+. Ductless mini-splits and heat pumps are also options, with heat pumps offering federal tax credits. All installations require a mechanical permit under the NJ Uniform Construction Code, and often an electrical permit, with mandatory inspections. Given the mixed-humid climate with cold winters, a central AC paired with a gas furnace is a common choice.

- SEER2 minimum13.4 SEER2 (North)

- Load calculationRecommended

- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Work falls under the NJ Uniform Construction Code (NJAC 5:23); a mechanical (and often electrical) permit plus inspection is required even for a like-for-like changeout.
