AC installation cost by system.
Installed pricing for Caledonia, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Caledonia, Wisconsin, where the median home was built in 1978 and homeownership is high at 77.4%, many homeowners are considering AC installation to replace aging systems. Typical costs for a like-for-like central AC replacement range from $4,000 to $8,000, while a new central AC with ductwork can run $6,000 to $13,000 or more. Ductless mini-splits and heat pumps are also options, with heat pumps costing $5,000 to $12,000+. Given the cold climate, a gas furnace paired with an AC is a common and practical choice.

Recommended unit for Caledonia
Given Wisconsin’s cold climate and gas heating, high-seer2 ac + gas furnace is the sensible default for most Caledonia homes. The cooling season is short, so the budget is better spent on heating efficiency than on ultra-high SEER2. A pro can confirm the right size and system for your home with a load calculation.

What Affects AC Installation Costs in Caledonia
Prices vary based on system type, efficiency, and existing ductwork. Like-for-like replacements are more affordable, while adding ductwork or upgrading to a heat pump increases costs.
