The quote form takes a ZIP code; for Oak Creek that is 53154 (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 15,728 occupied homes in Oak Creek, 71% heat with natural gas, 0% with heating oil, 26% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5558800, checked 2026-10-19).
Gas heats 71% of Oak Creek against electricity at 26%, 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.
Oak Creek has about the Milwaukee County oil share of 1% and 7 points more electric heat than the county's 19% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US55079, checked 2026-10-19).
Oak Creek has 16,183 housing units, 3% built before 1940 and 36% before 1980, with 31% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5558800, checked 2026-10-19).
Oak Creek has 25 points fewer pre-1940 homes than Milwaukee County as a whole (28%) and 21 points more homes built after 2000 than the county's 10% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US55079, checked 2026-10-19).
The median Oak Creek home was built in 1991 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5558800, 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=160XX00US5558800, checked 2026-10-19).
53% of Oak Creek homes are single-family detached, 7% are in two- to four-unit buildings and 34% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5558800, checked 2026-10-19).
43% of Oak Creek homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5558800, checked 2026-10-19), so beside the 53% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Oak Creek has 8 points more detached houses than Milwaukee County overall (45%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US55079, checked 2026-10-19).
43% of Oak Creek homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5558800, 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.
No electric utility is on file for Oak Creek 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 Oak Creek address before counting it. With 26% of Oak Creek 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 Oak Creek is $96,555 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5558800, 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.

That -5F figure is the Milwaukee County cold-day number a Oak Creek 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 71% of Oak Creek on gas and 26% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Oak Creek home has 5.2 rooms and was built around 1991, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
