AC installation cost by system.
Installed pricing for Robertsville, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Robertsville, New Jersey, AC installation costs typically range from $3,700 to $7,500 for a like-for-like central AC replacement. For new systems with ductwork, expect $5,600 to $12,200, while ductless mini-splits run $2,800 to $7,500 and heat pumps $4,700 to $11,200.

A mechanical permit and inspection are required for any AC installation, including like-for-like changes. The mixed-humid climate with cold winters makes a gas furnace paired with a high-efficiency AC a recommended system choice.
