AC installation cost by system.
Installed pricing for Hillsdale, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Hillsdale, NJ, where the median home was built in 1959 and homeownership is 88.3%, AC installation is a common upgrade for aging systems. Local pricing for a like-for-like central AC replacement ranges from $3,700 to $7,500+, while a new system with ductwork runs $5,600 to $12,200+. Ductless mini-splits cost $2,800–$7,500, and heat pumps $4,700–$11,200+. With cold winters and moderate cooling demand, many homeowners pair a high-efficiency AC with a gas furnace. Work must comply with the NJ Uniform Construction Code, requiring a mechanical permit and inspection—even for a like-for-like changeout. This adds to the cost but ensures safety and code compliance.
