White Plains / Ardsley
Ardsley is about 5 miles from the Census center point for White Plains in a straight line and covers 1.321 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).
Ardsley has 4,998 residents (give or take 23) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3602506, checked 2026-10-19), about 3,783 people per square mile.
The quote form takes a ZIP code; for Ardsley that is 10502 (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).
3,783 people per square mile puts Ardsley in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 1,626 occupied homes in Ardsley, 74% heat with natural gas, 13% with heating oil, 9% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3602506, checked 2026-10-19).
Ardsley has 15 points less oil heat than Westchester County as a whole, where 28% of homes burn oil, and 5 points less 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).
Gas leads in Ardsley at 74%, but 15% of homes still burn delivered oil or propane, and those 244 or so homes are where a heat pump pays back fastest.
The median Ardsley home was built in 1958 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3602506, checked 2026-10-19) and the median home has 6.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3602506, checked 2026-10-19).
Ardsley has 1,728 housing units, 11% built before 1940 and 69% before 1980, with 21% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3602506, checked 2026-10-19).
Ardsley has 17 points fewer pre-1940 homes than Westchester County as a whole (28%) and 10 points more 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).
69% of Ardsley homes were built before 1980 and only 21% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3602506, 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.
71% of Ardsley homes are single-family detached, 5% are in two- to four-unit buildings and 20% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3602506, checked 2026-10-19).
With 71% detached houses and 5% in small multi-family buildings, a Ardsley quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 19% of Ardsley homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3602506, checked 2026-10-19), the landlord signs the quote in many of them.
Ardsley has 28 points more detached houses than Westchester County overall (43%) and 15 points fewer 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).
No electric utility is on file for Ardsley 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 Ardsley address before counting it. With 9% of Ardsley homes already on electric heat and 90% 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 Ardsley is $243,000 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3602506, 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: 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 Ardsley 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 74% of Ardsley on gas and 9% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Ardsley home has 6.6 rooms and was built around 1958, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
