AC installation cost by system.
Installed pricing for Columbia, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Columbia, TN, AC installation costs typically range from $3,500 to $7,000 for a like-for-like central AC replacement, and $5,200 to $11,400+ if new ductwork is needed. Ductless mini-splits run $2,600–$7,000, while heat pumps—a recommended choice given the mixed-humid climate and mostly electric heating—cost $4,400–$10,500+. These prices reflect local labor, materials, and the required mechanical permit from the city. Tennessee mandates a minimum SEER2 of 14.3 for systems under 45,000 BTU in the Southeast region, and new refrigerants like R-454B or R-32 are now standard as R-410A is phased out. A load calculation is strong practice to ensure proper sizing.
