White Plains / Mount Vernon
Mount Vernon has 72,427 residents (give or take 103) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3649121, checked 2026-10-19), about 16,491 people per square mile.
Mount Vernon is about 9 miles from the Census center point for White Plains in a straight line and covers 4.392 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 Mount Vernon that is 10550, 10552, 10553 (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 Mount Vernon is $78,779 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3649121, 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 16,491 people per square mile, Mount Vernon is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
27% of Mount Vernon homes are single-family detached, 19% are in two- to four-unit buildings and 48% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3649121, checked 2026-10-19).
With 48% of Mount Vernon homes in buildings of five or more units and 27% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 57% of Mount Vernon homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3649121, checked 2026-10-19), the landlord signs the quote in many of them.
Mount Vernon has 16 points fewer detached houses than Westchester County overall (43%) and 13 points more five-plus-unit buildings than the county's 35% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US36119, checked 2026-10-19).
57% of Mount Vernon homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3649121, 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 28,078 occupied homes in Mount Vernon, 49% heat with natural gas, 28% with heating oil, 17% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3649121, checked 2026-10-19).
Gas leads in Mount Vernon at 49%, but 30% of homes still burn delivered oil or propane, and those 8,423 or so homes are where a heat pump pays back fastest.
Mount Vernon has about the Westchester County oil share of 28% and 3 points more electric heat than the county's 14% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US36119, checked 2026-10-19).
No electric utility is on file for Mount Vernon 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 Mount Vernon address before counting it. With 17% of Mount Vernon homes already on electric heat and 79% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Mount Vernon has 30,080 housing units, 34% built before 1940 and 82% before 1980, with 6% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3649121, checked 2026-10-19).
Mount Vernon has 6 points more pre-1940 homes than Westchester County as a whole (28%) and 5 points fewer homes built after 2000 than the county's 11% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US36119, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Mount Vernon home was built in 1953 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3649121, checked 2026-10-19) and the median home has 4.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3649121, checked 2026-10-19).
34% of Mount Vernon homes were built before 1940 and 82% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3649121, checked 2026-10-19), so insulation is the first sizing question: an older home leaks more heat per square foot, and the installer runs a room-by-room heat-loss calculation to size the system for what the walls and windows actually hold in, not just the floor plan.
Heating design temperature: 6F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Westchester 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 6F figure is the Westchester County cold-day number a Mount Vernon heat pump is sized against, so ask the installer to show the system's heating output at 6F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 49% of Mount Vernon on gas and 17% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Mount Vernon house from before 1940 (34% of the 30,080 units) rarely matches a square-footage rule of thumb.
