Haddonfield is about 5 miles from the Census center point for Camden in a straight line and covers 2.796 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).
Haddonfield has 12,595 residents (give or take 28) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3428770, checked 2026-10-19), about 4,505 people per square mile.
The quote form takes a ZIP code; for Haddonfield that is 08033 (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).
4,505 people per square mile puts Haddonfield in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 4,226 occupied homes in Haddonfield, 81% heat with natural gas, 5% with heating oil, 12% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3428770, checked 2026-10-19).
Haddonfield has about the Camden County oil share of 4% and 6 points less electric heat than the county's 18% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US34007, checked 2026-10-19).
Gas heats 81% of Haddonfield against electricity at 12%, 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 Haddonfield home was built in 1938 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3428770, checked 2026-10-19) and the median home has 7.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3428770, checked 2026-10-19).
Haddonfield has 4,470 housing units, 50% built before 1940 and 87% before 1980, with 8% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3428770, checked 2026-10-19).
Haddonfield has 33 points more pre-1940 homes than Camden County as a whole (17%) and 3 points fewer homes built after 2000 than the county's 11% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US34007, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
50% of Haddonfield homes were built before 1940 and 87% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3428770, 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.
81% of Haddonfield homes are single-family detached, 4% 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=160XX00US3428770, checked 2026-10-19).
With 81% detached houses and 4% in small multi-family buildings, a Haddonfield quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 17% of Haddonfield homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3428770, checked 2026-10-19), the landlord signs the quote in many of them.
Haddonfield has 26 points more detached houses than Camden County overall (55%) and 12 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=050XX00US34007, checked 2026-10-19).
No electric utility is on file for Haddonfield on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Median household income in Haddonfield is $200,400 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3428770, 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. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Camden 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 10F figure is the Camden County cold-day number a Haddonfield 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 81% of Haddonfield on gas and 12% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Haddonfield house from before 1940 (50% of the 4,470 units) rarely matches a square-footage rule of thumb.
