AC installation cost by system.
Installed pricing for West Plains, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In West Plains, Missouri, AC installation costs typically range from $3,100 to $6,100 for a like-for-like central AC replacement, and $4,600 to $9,900+ if new ductwork is needed. Ductless mini-splits run $2,300–$6,100, while heat pumps are $3,800–$9,200+.

The federal 25C tax credit offers up to $600 for high-efficiency central AC or up to $2,000 for a qualifying heat pump, helping offset costs.
