Hempstead / Hempstead
Hempstead has 58,801 residents (give or take 60) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3633139, checked 2026-10-19), about 15,931 people per square mile.
Hempstead is the city this door is named for; it covers 3.691 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 Hempstead that is 11550 (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).
Median household income in Hempstead is $90,420 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3633139, 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.
At 15,931 people per square mile, Hempstead is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
44% of Hempstead homes are single-family detached, 10% are in two- to four-unit buildings and 44% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3633139, checked 2026-10-19).
With 44% of Hempstead homes in buildings of five or more units and 44% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 53% of Hempstead homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3633139, checked 2026-10-19), the landlord signs the quote in many of them.
Hempstead has 32 points fewer detached houses than Nassau County overall (76%) and 31 points more 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).
53% of Hempstead homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3633139, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
Of the 17,108 occupied homes in Hempstead, 72% heat with natural gas, 14% with heating oil, 10% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3633139, checked 2026-10-19).
Gas leads in Hempstead at 72%, but 17% of homes still burn delivered oil or propane, and those 2,908 or so homes are where a heat pump pays back fastest.
Hempstead has 12 points less oil heat than Nassau County as a whole, where 26% of homes burn oil, and 3 points more 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).
No electric utility is on file for Hempstead 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 Hempstead address before counting it. With 10% of Hempstead homes already on electric heat and 88% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Hempstead has 18,747 housing units, 19% built before 1940 and 85% before 1980, with 9% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3633139, checked 2026-10-19).
Hempstead 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).
The median Hempstead home was built in 1958 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3633139, checked 2026-10-19) and the median home has 4.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3633139, checked 2026-10-19).
85% of Hempstead homes were built before 1980 and only 9% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3633139, 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.
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 Hempstead 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 72% of Hempstead on gas and 10% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Hempstead home has 4.9 rooms and was built around 1958, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
