AC installation cost by system.
Installed pricing for University City, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In University City, MO, AC installation costs typically range from $3,700 to $7,400 for a like-for-like central AC replacement, $5,600 to $12,100+ for a new system with ductwork, $2,800 to $7,400 for a ductless mini-split, and $4,600 to $11,100+ for a heat pump. With a median home age of 75 years, many homes have aging ductwork and electrical systems that can increase project complexity. Missouri's lack of a statewide mechanical code means University City sets its own permit and inspection requirements, so always check local rules before starting work. The mixed-humid climate and moderate cooling demand make an AC-gas furnace combination a well-suited choice for most homes.

- Good to know—
