Hempstead / Island Park
Island Park is about 7 miles from the Census center point for Hempstead in a straight line and covers 0.445 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).
Island Park has 4,976 residents (give or take 16) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3637847, checked 2026-10-19), about 11,182 people per square mile.
The quote form takes a ZIP code; for Island Park that is 11558 (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 11,182 people per square mile, Island Park 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 1,815 occupied homes in Island Park, 76% heat with natural gas, 6% with heating oil, 8% with electricity and 6% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3637847, checked 2026-10-19).
Island Park has 20 points less oil heat than Nassau County as a whole, where 26% of homes burn oil, and 1 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).
Gas heats 76% of Island Park against electricity at 8%, 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 Island Park home was built in 1960 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3637847, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3637847, checked 2026-10-19).
Island Park has 1,930 housing units, 14% built before 1940 and 67% before 1980, with 19% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3637847, checked 2026-10-19).
Island Park has 5 points fewer pre-1940 homes than Nassau County as a whole (19%) and 12 points more homes built after 2000 than the county's 7% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US36059, checked 2026-10-19).
67% of Island Park homes were built before 1980 and only 19% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3637847, 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.
55% of Island Park homes are single-family detached, 31% are in two- to four-unit buildings and 9% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3637847, checked 2026-10-19).
41% of Island Park homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3637847, checked 2026-10-19), so beside the 55% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Island Park has 21 points fewer detached houses than Nassau County overall (76%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US36059, checked 2026-10-19).
41% of Island Park homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3637847, 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.
No electric utility is on file for Island Park 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 Island Park address before counting it. With 8% of Island Park 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.
Median household income in Island Park is $104,926 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3637847, 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.

That 9F figure is the Nassau County cold-day number a Island Park 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 76% of Island Park 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 Island Park home has 5.6 rooms and was built around 1960, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
