White Plains / Katonah
Katonah is about 16 miles from the Census center point for White Plains in a straight line and covers 0.734 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).
Katonah has 2,176 residents (give or take 561) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3638946, checked 2026-10-19), about 2,965 people per square mile.
Of the 710 occupied homes in Katonah, 36% heat with natural gas, 55% with heating oil, 7% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3638946, checked 2026-10-19).
Katonah has 27 points more oil heat than Westchester County as a whole, where 28% of homes burn oil, and 7 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).
Heating oil is the largest single fuel in Katonah at 55%, ahead of gas at 36%, so the usual job here is an oil boiler or furnace coming out and a cold-climate heat pump going in, with the oil tank removed.
The median Katonah home was built in 1948 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3638946, checked 2026-10-19) and the median home has 6.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3638946, checked 2026-10-19).
Katonah has 787 housing units, 34% built before 1940 and 90% before 1980, with 1% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3638946, checked 2026-10-19).
Katonah has 6 points more pre-1940 homes than Westchester County as a whole (28%) and 10 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.
34% of Katonah homes were built before 1940 and 90% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3638946, 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.
82% of Katonah homes are single-family detached, 12% are in two- to four-unit buildings and 3% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3638946, checked 2026-10-19).
With 82% detached houses and 12% in small multi-family buildings, a Katonah quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 29% of Katonah homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3638946, checked 2026-10-19), the landlord signs the quote in many of them.
Katonah has 39 points more detached houses than Westchester County overall (43%) and 32 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 Katonah 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 Katonah address before counting it. With 7% of Katonah homes already on electric heat and 93% 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 Katonah is $207,083 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3638946, 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 Katonah 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 what happens to the oil tank, since 55% of the 710 occupied Katonah homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; a Katonah house from before 1940 (34% of the 787 units) rarely matches a square-footage rule of thumb.
