Hempstead / Babylon
Babylon has 12,185 residents (give or take 24) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3603408, checked 2026-10-19), about 5,054 people per square mile.
Babylon is about 15 miles from the Census center point for Hempstead in a straight line and covers 2.411 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 Babylon that is 11702 (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).
5,054 people per square mile puts Babylon in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 4,650 occupied homes in Babylon, 66% heat with natural gas, 24% 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=160XX00US3603408, checked 2026-10-19).
Gas leads in Babylon at 66%, but 25% of homes still burn delivered oil or propane, and those 1,163 or so homes are where a heat pump pays back fastest.
Babylon has 20 points less oil heat than Suffolk County as a whole, where 44% of homes burn oil, and 1 points less electric heat than the county's 9% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US36103, checked 2026-10-19).
Babylon has 4,795 housing units, 26% built before 1940 and 86% before 1980, with 4% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3603408, checked 2026-10-19).
Babylon has 17 points more pre-1940 homes than Suffolk County as a whole (9%) and 9 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=050XX00US36103, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Babylon home was built in 1956 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3603408, 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=160XX00US3603408, checked 2026-10-19).
74% of Babylon homes are single-family detached, 12% 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=160XX00US3603408, checked 2026-10-19).
With 74% detached houses and 12% in small multi-family buildings, a Babylon quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 21% of Babylon homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3603408, checked 2026-10-19), the landlord signs the quote in many of them.
Babylon has 6 points fewer detached houses than Suffolk County overall (80%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US36103, checked 2026-10-19).
86% of Babylon homes were built before 1980 and only 4% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3603408, 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 Babylon on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
NYS Clean Heat (Con Edison), run by Con Edison, is a live program for New York addresses and lists a standard figure of $7,000 (registry row 5 verified 2026-10-16, https://www.coned.com/en/save-money/rebates-incentives-tax-credits/rebates-incentives-tax-credits-for-residential-customers/electric-heating-and-cooling-technology-for-renters-homeowners/save-on-a-central-air-source-heat-pump, checked 2026-10-16); confirm eligibility for the Babylon address before counting it. With 8% of Babylon homes already on electric heat and 91% 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 Babylon is $140,820 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3603408, 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: 7F.

That 7F figure is the Suffolk County cold-day number a Babylon heat pump is sized against, so ask the installer to show the system's heating output at 7F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 66% of Babylon 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; the median Babylon home has 6.3 rooms and was built around 1956, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
