Madison / Beaver Dam
Beaver Dam has 16,565 residents (give or take 91) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5505900, checked 2026-10-19), about 2,231 people per square mile.
Beaver Dam is about 40 miles from the Census center point for Madison in a straight line and covers 7.424 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 7,571 occupied homes in Beaver Dam, 66% heat with natural gas, 1% with heating oil, 28% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5505900, checked 2026-10-19).
Gas heats 66% of Beaver Dam against electricity at 28%, 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.
Beaver Dam has about the Dodge County oil share of 3% and 11 points more electric heat than the county's 17% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US55027, checked 2026-10-19).
Beaver Dam has 7,831 housing units, 28% built before 1940 and 66% before 1980, with 20% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5505900, checked 2026-10-19).
Beaver Dam tracks Dodge County on housing age, with the county at 28% pre-1940 and 18% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US55027, checked 2026-10-19).
The median Beaver Dam home was built in 1963 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5505900, checked 2026-10-19) and the median home has 5.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5505900, checked 2026-10-19).
59% of Beaver Dam homes are single-family detached, 11% are in two- to four-unit buildings and 26% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5505900, checked 2026-10-19).
45% of Beaver Dam homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5505900, checked 2026-10-19), so beside the 59% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Beaver Dam has 13 points fewer detached houses than Dodge County overall (72%) and 13 points more five-plus-unit buildings than the county's 13% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US55027, checked 2026-10-19).
45% of Beaver Dam homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5505900, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
66% of Beaver Dam homes were built before 1980 and only 20% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5505900, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
No electric utility is on file for Beaver Dam 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 Beaver Dam address before counting it. With 28% of Beaver Dam homes already on electric heat and 68% 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 Beaver Dam is $66,673 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5505900, 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: -5F.

That -5F figure is the Dodge County cold-day number a Beaver Dam heat pump is sized against, so ask the installer to show the system's heating output at -5F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 66% of Beaver Dam on gas and 28% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Beaver Dam home has 5.2 rooms and was built around 1963, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
