Madison / Belleville
Belleville is about 16 miles from the Census center point for Madison in a straight line and covers 1.589 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
Belleville has 2,579 residents (give or take 296) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5506300, checked 2026-10-19), about 1,623 people per square mile.
Of the 1,077 occupied homes in Belleville, 80% heat with natural gas, 1% with heating oil, 17% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5506300, checked 2026-10-19).
Belleville has about the Dane County oil share of 0% and 8 points less electric heat than the county's 25% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US55025, checked 2026-10-19).
Gas heats 80% of Belleville against electricity at 17%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
The median Belleville home was built in 1990 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5506300, checked 2026-10-19) and the median home has 5.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5506300, checked 2026-10-19).
Belleville has 1,096 housing units, 13% built before 1940 and 40% before 1980, with 22% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5506300, checked 2026-10-19).
Belleville has 3 points more pre-1940 homes than Dane County as a whole (10%) and 11 points fewer homes built after 2000 than the county's 33% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US55025, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
72% of Belleville homes are single-family detached, 6% are in two- to four-unit buildings and 12% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5506300, checked 2026-10-19).
With 72% detached houses and 6% in small multi-family buildings, a Belleville quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 18% of Belleville homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5506300, checked 2026-10-19), the landlord signs the quote in many of them.
Belleville has 22 points more detached houses than Dane County overall (50%) and 22 points fewer five-plus-unit buildings than the county's 34% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US55025, checked 2026-10-19).
No electric utility is on file for Belleville on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Focus on Energy air source heat pump instant discount (ratepayer), run by Focus on Energy, is a live program for Wisconsin addresses and covers qualifying equipment at $900 per system (registry row 20 verified 2026-10-07, https://assets.focusonenergy.com/production/docs/trade-ally/TAS-Trade-Ally-Solutions-Rebates-Overview-20260101_CLEAN.pdf, checked 2026-10-16); confirm eligibility for the Belleville address before counting it. With 17% of Belleville homes already on electric heat and 82% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in Belleville is $88,304 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5506300, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.
Heating design temperature: -6F.

That -6F figure is the Dane County cold-day number a Belleville heat pump is sized against, so ask the installer to show the system's heating output at -6F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 80% of Belleville on gas and 17% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Belleville home has 5.8 rooms and was built around 1990, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
