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