Furnace repair cost by part.
Typical Wausau repair pricing including parts and labor. A diagnostic fee usually applies and is often credited toward the work.
In Wausau, Wisconsin, furnace repair costs vary with the age of the home—many were built around 1960—and the severity of winter. A typical diagnostic fee runs $65–$175, with common repairs like flame sensor replacement ($70–$225) or igniter ($125–$400). Wisconsin requires a mechanical permit and a licensed DSPS contractor for any furnace work, even like-for-like changeouts. Most homes use gas heating, and equipment must be sized for severe cold. The federal 25C tax credit (up to $600 for high-efficiency AC) is available, but furnace repairs themselves do not qualify.

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