White Plains / Suffern
Suffern has 11,441 residents (give or take 31) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US3671894, checked 2026-10-19), about 5,456 people per square mile.
Suffern is about 21 miles from the Census center point for White Plains in a straight line and covers 2.097 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).
Median household income in Suffern is $104,607 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3671894, 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.
5,456 people per square mile puts Suffern in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
28% of Suffern homes are single-family detached, 33% are in two- to four-unit buildings and 23% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US3671894, checked 2026-10-19).
33% of Suffern homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3671894, checked 2026-10-19), so beside the 28% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Suffern has 29 points fewer detached houses than Rockland County overall (57%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US36087, checked 2026-10-19).
Of the 4,600 occupied homes in Suffern, 82% heat with natural gas, 3% with heating oil, 11% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3671894, checked 2026-10-19).
Gas heats 82% of Suffern against electricity at 11%, 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.
Suffern has about the Rockland County oil share of 2% and 1 points more electric heat than the county's 10% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US36087, checked 2026-10-19).
No electric utility is on file for Suffern 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 Suffern address before counting it. With 11% of Suffern homes already on electric heat and 87% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Suffern has 4,784 housing units, 18% built before 1940 and 81% before 1980, with 5% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3671894, checked 2026-10-19).
Suffern has 7 points more pre-1940 homes than Rockland County as a whole (11%) and 9 points fewer homes built after 2000 than the county's 14% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US36087, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Suffern home was built in 1971 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3671894, checked 2026-10-19) and the median home has 4.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3671894, checked 2026-10-19).
81% of Suffern homes were built before 1980 and only 5% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3671894, 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.
Heating design temperature: 6F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Rockland 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 Rockland County cold-day number a Suffern 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 82% of Suffern on gas and 11% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Suffern home has 4.7 rooms and was built around 1971, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
