The Milwaukee market
Milwaukee's Department of Neighborhood Services lists furnaces and air conditioners as needing a permit (414-286-8210 for questions), and plumbing in an owner-occupied single-family home as permit work (414-286-8208), though water heaters are not named. Another city page lists replacing mechanical appliances, including air conditioners, as no-permit work, likely meaning room units; confirm before relying on it. Heating appliances cost $55 per unit up to 150,000 Btu input, boilers $60, and AC units $60 up to 3 tons plus $10 per extra ton. Plumbing is $20 per fixture with an $85 minimum for one fixture in a 1-2 family building. Owner-occupants can do their own plumbing and HVAC work; contractors must be licensed. Wisconsin leans gas: EIA's 2020 survey found 71% of homes heat with natural gas and 78% use a furnace. Focus on Energy runs statewide rebates.
Wisconsin's federally funded HEAR and HOMES rebates are available through Focus on Energy, with HEAR limited to households at or below 150% of area median income. In a gas-heated cold market, a heat pump paired with the existing furnace is a common approach to price. Ask at what outdoor temperature the furnace takes over, and ask for the heat pump's rated capacity in cold weather before you compare bids.
