AC maintenance & tune-up cost.
Typical Grafton pricing for seasonal service, adjusted for local labor. Plans that bundle two visits a year lower the per-visit cost.
In Grafton, Wisconsin, a typical AC tune-up costs between $65 and $175 for a single visit, with coil cleaning adding $90 to $350. Many homeowners opt for an annual plan ($125–$325 for two visits) to keep their system efficient. Because the median home was built in 1985, older equipment may need more attention during a tune-up. Wisconsin requires a mechanical permit for any AC work, and a licensed DSPS contractor must perform the service. Given the cold climate, most homes use a gas furnace with central AC, so tune-ups often include checking both systems. The federal 25C tax credit offers up to $600 for a high-efficiency central AC, but routine maintenance itself does not qualify.

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