AC installation cost by system.
Installed pricing for Franklin, adjusted for local labor. Higher SEER2 tiers, larger tonnage, and new ductwork add to the base.
Franklin, Ohio homeowners considering central air conditioning installation can expect costs that vary with home size, existing ductwork, and system efficiency. With a median home age of 59 years, many homes may need ductwork modifications or full replacement, adding to project costs. Local permits are required per Ohio Mechanical Code, and post-install inspection is typical. Given the mixed-humid climate and moderate cooling demand, a matched AC and gas furnace system is a common choice. Federal tax credits up to $600 for high-efficiency AC units (30% of cost) can offset expenses.

Higher SEER2 units qualify for federal tax credits but have higher upfront costs.
