Installed pricing for Franklin, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
In Franklin, Wisconsin, AC installation costs typically range from $4,000 to $8,100 for a like-for-like central AC replacement, and $6,100 to $13,200+ if new ductwork is needed. Ductless mini-splits run $3,000–$8,100, while heat pumps cost $5,100–$12,100+. With a median home age of 36 years, many homes may require duct modifications or system upgrades.

Recommended unit for Franklin
Given Wisconsin’s cold climate and gas heating, high-seer2 ac + gas furnace is the sensible default for most Franklin 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.

AC Installation in Franklin, explained.
What Affects AC Installation Cost in Franklin
Labor and permit fees in Franklin reflect the requirement for a licensed Wisconsin HVAC contractor. System choice—central AC vs. ductless vs. heat pump—drives the base price. Older homes (median built 1990) may need ductwork repairs or resizing, adding $2,000–$5,000. Efficiency level also matters: higher SEER2 units cost more upfront but qualify for federal tax credits. Finally, cold-climate sizing for severe winter design temps can require larger equipment, increasing cost.
Common AC Installation Issues in Franklin
Permit and Code Compliance
Wisconsin requires a mechanical permit for all AC installations; failing to pull one can lead to fines and issues when selling the home.
Older Ductwork
Many Franklin homes built around 1990 have ducts sized for older, less efficient systems; replacement may be needed for proper airflow.
Cold-Climate Sizing
Equipment must handle severe winter design temps, so oversizing for cooling alone can cause short cycling and poor dehumidification.
