Newark / Westfield
Westfield has 31,111 residents (give or take 47) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3479040, checked 2026-10-19), about 4,627 people per square mile.
Westfield is about 10 miles from the Census center point for Newark in a straight line and covers 6.724 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
The quote form takes a ZIP code; for Westfield that is 07090 (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).
4,627 people per square mile puts Westfield in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 10,900 occupied homes in Westfield, 87% heat with natural gas, 4% with heating oil, 8% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3479040, checked 2026-10-19).
Gas heats 87% of Westfield 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.
Westfield has about the Union County oil share of 4% and 3 points less electric heat than the county's 11% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US34039, checked 2026-10-19).
Westfield has 11,192 housing units, 37% built before 1940 and 79% before 1980, with 12% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3479040, checked 2026-10-19).
Westfield has 13 points more pre-1940 homes than Union County as a whole (24%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US34039, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Westfield home was built in 1953 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3479040, checked 2026-10-19) and the median home has 7.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3479040, checked 2026-10-19).
78% of Westfield homes are single-family detached, 12% are in two- to four-unit buildings and 7% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3479040, checked 2026-10-19).
With 78% detached houses and 12% in small multi-family buildings, a Westfield quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 19% of Westfield homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3479040, checked 2026-10-19), the landlord signs the quote in many of them.
Westfield has 28 points more detached houses than Union County overall (50%) and 13 points fewer five-plus-unit buildings than the county's 20% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US34039, checked 2026-10-19).
37% of Westfield homes were built before 1940 and 79% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3479040, 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.
No electric utility is on file for Westfield 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 Westfield address before counting it. With 8% of Westfield homes already on electric heat and 92% 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 Westfield is $232,629 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3479040, 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), Union 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 Union County cold-day number a Westfield 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 87% of Westfield 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; a Westfield house from before 1940 (37% of the 11,192 units) rarely matches a square-footage rule of thumb.
