AC repair cost by part.
Typical Grafton repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
AC repair costs in Grafton, Wisconsin, typically range from $65–$175 for a diagnostic fee, plus labor and parts. Common repairs include capacitor replacement ($125–$350), refrigerant recharge ($225–$650+), and fan motor replacement ($325–$800). Because Grafton is a cold-climate area, equipment must be sized for severe winter design temperatures, and a mechanical permit is required for any repair involving refrigerant or electrical work. Most homes were built around 1985, so older systems may need more frequent repairs or upgrades. For central AC repairs, a licensed Wisconsin HVAC contractor (DSPS) must perform the work, even for like-for-like replacements. The federal 25C tax credit offers up to $600 for a high-efficiency central AC, which can offset some costs.

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.
