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.

AC Installation in Wauwatosa, explained.
What affects AC installation costs in Wauwatosa
Older homes (median 1953) may need ductwork modifications or new ductwork, increasing costs. System choice matters: a heat pump costs more upfront than a standard AC but qualifies for the federal 25C tax credit (30%, up to $2,000). Permit fees and contractor licensing add to labor costs. The cold climate requires proper sizing for winter design temps, which may mean a higher-efficiency unit. Low cooling demand means homeowners often opt for a more affordable AC-gas furnace combo.
