Of the 25,757 occupied homes in Old Bridge, 83% 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=060XX00US3402354705, checked 2026-10-19).
Gas heats 83% of Old Bridge 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.
Old Bridge has about the Middlesex County oil share of 3% and 5 points less electric heat than the county's 15% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US34023, checked 2026-10-19).
Old Bridge has 26,787 housing units, 5% built before 1940 and 59% before 1980, with 14% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3402354705, checked 2026-10-19).
Old Bridge has 5 points fewer pre-1940 homes than Middlesex County as a whole (10%) and 3 points fewer homes built after 2000 than the county's 17% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US34023, checked 2026-10-19).
The median Old Bridge home was built in 1972 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3402354705, checked 2026-10-19) and the median home has 5.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3402354705, checked 2026-10-19).
57% of Old Bridge homes are single-family detached, 10% 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=060XX00US3402354705, checked 2026-10-19).
30% of Old Bridge homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3402354705, checked 2026-10-19), so beside the 57% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Old Bridge has 5 points more detached houses than Middlesex County overall (52%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US34023, checked 2026-10-19).
No electric utility is on file for Old Bridge 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 Old Bridge address before counting it. With 10% of Old Bridge homes already on electric heat and 88% 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 Old Bridge is $104,587 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3402354705, 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: 10F.

That 10F figure is the Middlesex County cold-day number a Old Bridge heat pump is sized against, so ask the installer to show the system's heating output at 10F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 83% of Old Bridge 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 Old Bridge home has 5.7 rooms and was built around 1972, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
