AC installation cost by system.
Installed pricing for New Milford, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In New Milford, NJ, where the median home was built in 1954, many older homes lack central AC or have outdated systems. Installing a new AC typically costs between $3,700 and $7,500 for a like-for-like central unit, while a new system with ductwork ranges from $5,600 to $12,200+. Ductless mini-splits and heat pumps are also options, with heat pumps qualifying for a federal tax credit of up to $2,000. Given New Milford's mixed-humid climate and moderate cooling demand, a gas furnace paired with a high-efficiency central AC is a common recommendation. All installations require a mechanical permit and inspection under the NJ Uniform Construction Code, adding to the overall cost.
