Camden / Hammonton
Hammonton has 14,840 residents (give or take 40) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3429430, checked 2026-10-19), about 364 people per square mile.
Hammonton is about 26 miles from the Census center point for Camden in a straight line and covers 40.749 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 Hammonton that is 08037 (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).
Hammonton is spread out at 364 people per square mile across 40.749 square miles of land, so a long refrigerant line run between the outdoor unit and the farthest indoor head is the sizing question an installer checks first.
Of the 5,721 occupied homes in Hammonton, 68% heat with natural gas, 11% with heating oil, 16% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3429430, checked 2026-10-19).
Gas heats 68% of Hammonton against electricity at 16%, 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.
Hammonton has 6 points more oil heat than Atlantic County as a whole, where 5% of homes burn oil, and 1 points less electric heat than the county's 17% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US34001, checked 2026-10-19).
Hammonton has 6,107 housing units, 19% built before 1940 and 63% before 1980, with 17% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3429430, checked 2026-10-19).
Hammonton has 5 points more pre-1940 homes than Atlantic County as a whole (14%) and 4 points fewer homes built after 2000 than the county's 21% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US34001, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Hammonton home was built in 1973 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3429430, checked 2026-10-19) and the median home has 6.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3429430, checked 2026-10-19).
68% of Hammonton homes are single-family detached, 13% are in two- to four-unit buildings and 12% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3429430, checked 2026-10-19).
29% of Hammonton homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3429430, checked 2026-10-19), so beside the 68% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Hammonton has 10 points more detached houses than Atlantic County overall (58%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US34001, checked 2026-10-19).
63% of Hammonton homes were built before 1980 and only 17% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3429430, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
No electric utility is on file for Hammonton 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 Hammonton is $78,087 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3429430, 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: 11F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Atlantic 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 11F figure is the Atlantic County cold-day number a Hammonton heat pump is sized against, so ask the installer to show the system's heating output at 11F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 68% of Hammonton on gas and 16% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Hammonton home has 6.3 rooms and was built around 1973, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
