Madison / Milton
Milton has 5,706 residents (give or take 34) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5552200, checked 2026-10-19), about 1,212 people per square mile.
Milton is about 33 miles from the Census center point for Madison in a straight line and covers 4.706 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).
Of the 2,485 occupied homes in Milton, 73% heat with natural gas, 0% with heating oil, 24% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5552200, checked 2026-10-19).
Gas heats 73% of Milton against electricity at 24%, 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.
Milton has about the Rock County oil share of 1% and 6 points more electric heat than the county's 18% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US55105, checked 2026-10-19).
Milton has 2,533 housing units, 24% built before 1940 and 57% before 1980, with 22% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5552200, checked 2026-10-19).
Milton has 5 points more pre-1940 homes than Rock County as a whole (19%) and 6 points more homes built after 2000 than the county's 16% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US55105, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Milton home was built in 1974 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5552200, checked 2026-10-19) and the median home has 5.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5552200, checked 2026-10-19).
71% of Milton homes are single-family detached, 11% are in two- to four-unit buildings and 13% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5552200, checked 2026-10-19).
With 71% detached houses and 11% in small multi-family buildings, a Milton quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 26% of Milton homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5552200, checked 2026-10-19), the landlord signs the quote in many of them.
No electric utility is on file for Milton 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 Milton address before counting it. With 24% of Milton homes already on electric heat and 73% 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 Milton is $85,959 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5552200, 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: -4F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Rock County row, 99% heating, PDF pages 137 to 140 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That -4F figure is the Rock County cold-day number a Milton heat pump is sized against, so ask the installer to show the system's heating output at -4F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 73% of Milton on gas and 24% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Milton home has 5.5 rooms and was built around 1974, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
