Hempstead / Elmont
Elmont is about 5 miles from the Census center point for Hempstead in a straight line and covers 3.41 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).
Elmont has 36,518 residents (give or take 2,253) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3624273, checked 2026-10-19), about 10,709 people per square mile.
The quote form takes a ZIP code; for Elmont that is 11003 (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).
At 10,709 people per square mile, Elmont is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
Of the 9,991 occupied homes in Elmont, 65% heat with natural gas, 23% with heating oil, 5% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3624273, checked 2026-10-19).
Elmont has 3 points less oil heat than Nassau County as a whole, where 26% of homes burn oil, and 2 points less electric heat than the county's 7% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US36059, checked 2026-10-19).
Gas leads in Elmont at 65%, but 26% of homes still burn delivered oil or propane, and those 2,598 or so homes are where a heat pump pays back fastest.
The median Elmont home was built in 1952 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3624273, 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=160XX00US3624273, checked 2026-10-19).
Elmont has 10,360 housing units, 18% built before 1940 and 89% before 1980, with 5% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3624273, checked 2026-10-19).
Elmont tracks Nassau County on housing age, with the county at 19% pre-1940 and 7% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US36059, checked 2026-10-19).
89% of Elmont homes were built before 1980 and only 5% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3624273, 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.
79% of Elmont homes are single-family detached, 13% are in two- to four-unit buildings and 2% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3624273, checked 2026-10-19).
With 79% detached houses and 13% in small multi-family buildings, a Elmont quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 21% of Elmont homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3624273, checked 2026-10-19), the landlord signs the quote in many of them.
Elmont has 11 points fewer five-plus-unit buildings than the county's 13% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US36059, checked 2026-10-19).
No electric utility is on file for Elmont 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 Elmont address before counting it. With 5% of Elmont 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 Elmont is $114,217 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3624273, 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), Nassau County row, 99% heating, PDF pages 84 to 86 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 Nassau County cold-day number a Elmont 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 65% of Elmont on gas and 5% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Elmont home has 6.3 rooms and was built around 1952, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
