Millburn has 22,145 residents (give or take 34) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3401346380, checked 2026-10-19), about 2,373 people per square mile.
The quote form takes a ZIP code; for Millburn that is 07041, 07078 (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 7,156 occupied homes in Millburn, 85% heat with natural gas, 3% with heating oil, 11% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3401346380, checked 2026-10-19).
Millburn has about the Essex County oil share of 4% and 8 points less electric heat than the county's 19% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US34013, checked 2026-10-19).
Gas heats 85% of Millburn against electricity at 11%, 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 Millburn home was built in 1954 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3401346380, checked 2026-10-19) and the median home has 8.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3401346380, checked 2026-10-19).
Millburn has 7,436 housing units, 33% built before 1940 and 87% before 1980, with 9% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3401346380, checked 2026-10-19).
Millburn has 4 points more pre-1940 homes than Essex County as a whole (29%) and 4 points fewer homes built after 2000 than the county's 13% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US34013, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
33% of Millburn homes were built before 1940 and 87% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3401346380, checked 2026-10-19), so insulation is the first sizing question: an older home leaks more heat per square foot, and the installer runs a room-by-room heat-loss calculation to size the system for what the walls and windows actually hold in, not just the floor plan.
79% of Millburn homes are single-family detached, 9% are in two- to four-unit buildings and 10% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3401346380, checked 2026-10-19).
With 79% detached houses and 9% in small multi-family buildings, a Millburn quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 19% of Millburn homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3401346380, checked 2026-10-19), the landlord signs the quote in many of them.
Millburn has 46 points more detached houses than Essex County overall (33%) and 21 points fewer five-plus-unit buildings than the county's 31% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US34013, checked 2026-10-19).
No electric utility is on file for Millburn 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 Millburn address before counting it. With 11% of Millburn 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 Millburn is $250,001 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3401346380, 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: 9F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Essex 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 9F figure is the Essex County cold-day number a Millburn heat pump is sized against, so ask the installer to show the system's heating output at 9F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 85% of Millburn on gas and 11% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Millburn house from before 1940 (33% of the 7,436 units) rarely matches a square-footage rule of thumb.
