Madison / New Berlin
New Berlin has 40,270 residents (give or take 55) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5556375, checked 2026-10-19), about 1,106 people per square mile.
New Berlin is about 66 miles from the Census center point for Madison in a straight line and covers 36.426 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).
The quote form takes a ZIP code; for New Berlin that is 53146, 53151 (Census 2020 ZCTA to county subdivision and ZCTA to place relationship files, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt and https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_place20_natl.txt, checked 2026-10-19).
Of the 17,064 occupied homes in New Berlin, 81% heat with natural gas, 1% with heating oil, 15% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5556375, checked 2026-10-19).
Gas heats 81% of New Berlin against electricity at 15%, 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.
New Berlin has about the Waukesha County oil share of 1% and 3 points less electric heat than the county's 18% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US55133, checked 2026-10-19).
New Berlin has 17,577 housing units, 4% built before 1940 and 53% before 1980, with 16% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5556375, checked 2026-10-19).
New Berlin has 3 points fewer pre-1940 homes than Waukesha County as a whole (7%) and 6 points fewer homes built after 2000 than the county's 22% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US55133, checked 2026-10-19).
The median New Berlin home was built in 1978 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5556375, checked 2026-10-19) and the median home has 6.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5556375, checked 2026-10-19).
69% of New Berlin homes are single-family detached, 3% are in two- to four-unit buildings and 21% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5556375, checked 2026-10-19).
24% of New Berlin homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5556375, checked 2026-10-19), so beside the 69% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
No electric utility is on file for New Berlin 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 New Berlin address before counting it. With 15% of New Berlin homes already on electric heat and 84% 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 New Berlin is $101,091 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5556375, 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 Waukesha County cold-day number a New Berlin 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 81% of New Berlin on gas and 15% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median New Berlin home has 6.3 rooms and was built around 1978, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
