AC installation cost by system.
Installed pricing for Iselin, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Iselin, New Jersey, a typical AC installation involves replacing an aging system in a home built around 1960. With median household income near $110,000 and a 65% homeownership rate, many residents invest in central AC or heat pump upgrades. Local pricing for a like-for-like central AC replacement ranges from $3,700 to $7,500, while new systems with ductwork can cost $5,600 to $12,200. Ductless mini-splits run $2,800 to $7,500, and heat pumps $4,700 to $11,200. The mixed-humid climate with cold winters makes a gas furnace paired with an AC a common choice. All installations require a mechanical permit under the NJ Uniform Construction Code, plus an electrical permit if needed, with inspections mandatory even for changeouts.
