The quote form takes a ZIP code; for West Windsor that is 08550 (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 11,552 occupied homes in West Windsor, 73% heat with natural gas, 2% with heating oil, 24% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3402180240, checked 2026-10-19).
West Windsor has 4 points less oil heat than Mercer County as a whole, where 6% of homes burn oil, and 5 points more electric heat than the county's 19% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US34021, checked 2026-10-19).
Gas heats 73% of West Windsor 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.
The median West Windsor home was built in 1990 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3402180240, 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=060XX00US3402180240, checked 2026-10-19).
West Windsor has 11,944 housing units, 3% built before 1940 and 23% before 1980, with 32% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3402180240, checked 2026-10-19).
West Windsor has 15 points fewer pre-1940 homes than Mercer County as a whole (18%) and 17 points more homes built after 2000 than the county's 15% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US34021, checked 2026-10-19).
55% of West Windsor homes are single-family detached, 5% are in two- to four-unit buildings and 30% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3402180240, checked 2026-10-19).
35% of West Windsor homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3402180240, checked 2026-10-19), so beside the 55% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
West Windsor has 7 points more detached houses than Mercer County overall (48%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US34021, checked 2026-10-19).
No electric utility is on file for West Windsor on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
JCP&L Clean Comfort (residential building decarbonization), run by JCP&L, is a live program for New Jersey addresses and covers qualifying equipment at $7,500 per system (registry row 8 verified 2026-10-15, https://www.neifund.org/wp-content/uploads/2026/04/0925_JCPL_Res_Bldg-Decarb_5860532_FRM_Rebate-Application_2025.pdf, checked 2026-10-16); confirm eligibility for the West Windsor address before counting it. With 24% of West Windsor homes already on electric heat and 76% 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 West Windsor is $197,190 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3402180240, 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 Mercer County cold-day number a West Windsor 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 73% of West Windsor 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 West Windsor home has 6.3 rooms and was built around 1990, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
