AC installation cost by system.
Installed pricing for North St. Paul, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In North St. Paul, where the median home was built in 1972, AC installation often involves replacing aging systems or adding new ductwork. Typical costs for a like-for-like central AC range from $3,500 to $7,000+, while a full system with new ducts can run $5,300 to $11,400+. Ductless mini-splits ($2,600–$7,000) and heat pumps ($4,400–$10,500+) are also options, especially for homes without existing ducts. Given the cold climate, dual-fuel systems (heat pump paired with gas furnace) are recommended for efficient heating and cooling. Minnesota requires a mechanical permit for AC installation, and gas-line work must be done by a licensed plumber or gas fitter. The federal 25C tax credit offers up to $2,000 for qualifying heat pumps and up to $600 for high-efficiency central AC.

- SEER2 minimum13.4 SEER2 (North)

- Load calculationRecommended

- Good to know—
Cold-climate sizing matters; gas-line work on a furnace must be done by a licensed plumber/gas fitter even if a homeowner pulls the mechanical permit.
