Hempstead / Franklin Square
Franklin Square is about 3 miles from the Census center point for Hempstead in a straight line and covers 2.88 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).
Franklin Square has 30,897 residents (give or take 2,049) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3627309, checked 2026-10-19), about 10,728 people per square mile.
The quote form takes a ZIP code; for Franklin Square that is 11010 (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 10,728 people per square mile, Franklin Square 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 9,745 occupied homes in Franklin Square, 63% heat with natural gas, 28% with heating oil, 2% with electricity and 6% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3627309, checked 2026-10-19).
Franklin Square has about the Nassau County oil share of 26% and 5 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 Franklin Square at 63%, but 34% of homes still burn delivered oil or propane, and those 3,313 or so homes are where a heat pump pays back fastest.
The median Franklin Square home was built in 1954 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3627309, checked 2026-10-19) and the median home has 6.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3627309, checked 2026-10-19).
Franklin Square has 10,067 housing units, 16% built before 1940 and 92% before 1980, with 4% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3627309, checked 2026-10-19).
Franklin Square has 3 points fewer pre-1940 homes than Nassau County as a whole (19%) and 3 points fewer 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).
92% of Franklin Square 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=160XX00US3627309, 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.
88% of Franklin Square homes are single-family detached, 9% are in two- to four-unit buildings and 1% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3627309, checked 2026-10-19).
With 88% detached houses and 9% in small multi-family buildings, a Franklin Square quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 17% of Franklin Square homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3627309, checked 2026-10-19), the landlord signs the quote in many of them.
Franklin Square has 12 points more detached houses than Nassau County overall (76%) and 12 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 Franklin Square 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 Franklin Square address before counting it. With 2% of Franklin Square homes already on electric heat and 97% 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 Franklin Square is $143,263 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3627309, 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 Franklin Square 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 63% of Franklin Square on gas and 2% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Franklin Square home has 6.4 rooms and was built around 1954, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
