AC installation cost by system.
Installed pricing for Martinsville, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Martinsville, NJ, AC installation costs typically range from $3,700 to $12,200+, depending on system type and complexity. With most homes built around 1971, many need like-for-like central AC replacements ($3,700–$7,500) or new ductwork ($5,600–$12,200+). Ductless mini-splits ($2,800–$7,500) and heat pumps ($4,700–$11,200+) are also options. Given the mixed-humid climate with cold winters, a gas furnace paired with a central AC is a common choice. All installations require a mechanical permit and inspection under the NJ Uniform Construction Code (NJAC 5:23), adding to labor costs. The federal 25C tax credit can offset up to $2,000 for qualifying heat pumps or $600 for high-efficiency central AC.
