AC installation cost by system.
Installed pricing for Tenafly, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Tenafly, NJ, where the median home was built in 1957, many homeowners face AC replacements in older homes with existing ductwork. Typical like-for-like central AC installation runs $3,700–$7,500+, while a new system with ductwork can cost $5,600–$12,200+. Ductless mini-splits range $2,800–$7,500, and heat pumps $4,700–$11,200+. Given the mixed-humid climate and moderate cooling demand, a gas furnace paired with a high-efficiency AC is a common choice. New Jersey requires a mechanical permit and inspection under the Uniform Construction Code—even for a like-for-like swap—so factor in permit fees and potential electrical work. Federal tax credits (up to $600 for qualifying central AC) can offset costs.
