The quote form takes a ZIP code; for Warren that is 07059 (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 5,376 occupied homes in Warren, 84% heat with natural gas, 4% with heating oil, 10% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3403576940, checked 2026-10-19).
Gas heats 84% of Warren against electricity at 10%, 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.
Warren has about the Somerset County oil share of 4% and 4 points less electric heat than the county's 14% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US34035, checked 2026-10-19).
Warren has 5,560 housing units, 4% built before 1940 and 40% before 1980, with 22% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3403576940, checked 2026-10-19).
Warren has 5 points fewer pre-1940 homes than Somerset County as a whole (9%) and 5 points more homes built after 2000 than the county's 17% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US34035, checked 2026-10-19).
The median Warren home was built in 1985 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3403576940, checked 2026-10-19) and the median home has 10 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3403576940, checked 2026-10-19).
87% of Warren homes are single-family detached, 1% are in two- to four-unit buildings and 8% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3403576940, checked 2026-10-19).
With 87% detached houses and 1% in small multi-family buildings, a Warren quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 12% of Warren homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3403576940, checked 2026-10-19), the landlord signs the quote in many of them.
Warren has 29 points more detached houses than Somerset County overall (58%) and 10 points fewer five-plus-unit buildings than the county's 18% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US34035, checked 2026-10-19).
Only 12% of Warren homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3403576940, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.
No electric utility is on file for Warren 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 Warren address before counting it. With 10% of Warren homes already on electric heat and 89% 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 Warren is $204,063 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3403576940, 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 Somerset County cold-day number a Warren 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 84% of Warren on gas and 10% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Warren home has 10 rooms and was built around 1985, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
