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, Missouri, central AC installation typically costs between $4,300 and $8,600 for a like-for-like replacement, and $6,400 to $14,000+ for a new system with ductwork. Ductless mini-splits range from $3,200 to $8,600, while heat pumps run $5,400 to $12,900+. Columbia's mixed-humid climate and moderate cooling demand make an AC-gas furnace combination a recommended system choice.

The federal 25C tax credit offers up to $600 for qualifying high-efficiency central AC units, reducing overall cost.

- SEER2 minimum13.4 SEER2 (North)
Federal North-region minimum for new split-system AC. Higher tiers cut bills and unlock rebates.
- Load calculationRecommended
Sizing by load calc — not rule of thumb — prevents an oversized unit that short-cycles and never dehumidifies.
- RefrigerantR-454B / R-32 (R-410A phased down 2025+)
- Good to know—
Missouri has no statewide residential building/mechanical code, so permit and inspection requirements are set locally by each city or county.
