Fuel mix

Of the 2,382 occupied homes in Green Brook, 89% heat with natural gas, 2% with heating oil, 8% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3403527510, checked 2026-10-19).

Gas heats 89% of Green Brook against electricity at 8%, 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.

Green Brook has about the Somerset County oil share of 4% and 6 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).

Housing stock

Green Brook has 2,432 housing units, 3% built before 1940 and 50% before 1980, with 22% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3403527510, checked 2026-10-19).

Green Brook has 6 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 Green Brook home was built in 1980 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3403527510, checked 2026-10-19) and the median home has 6.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3403527510, checked 2026-10-19).

71% of Green Brook homes are single-family detached, 3% are in two- to four-unit buildings and 17% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3403527510, checked 2026-10-19).

With 71% detached houses and 3% in small multi-family buildings, a Green Brook quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 7% of Green Brook homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3403527510, checked 2026-10-19), the landlord signs the quote in many of them.

Green Brook has 13 points more detached houses than Somerset County overall (58%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US34035, checked 2026-10-19).

Only 7% of Green Brook homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3403527510, 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.

Rebate path

No electric utility is on file for Green Brook 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 Green Brook address before counting it. With 8% of Green Brook homes already on electric heat and 91% 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 Green Brook is $208,375 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3403527510, 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.

Cold-day number

Heating design temperature: 6F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Somerset County row, 99% heating, PDF pages 81 to 82 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.

That 6F figure is the Somerset County cold-day number a Green Brook 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.

Next step

Ask whether the quote is whole-home or partial-home, because with 89% of Green Brook on gas and 8% already electric the two paths carry different rebate figures and different sizing.

Ask for the heat-loss calculation room by room; the median Green Brook home has 6.7 rooms and was built around 1980, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
