Of the 15,139 occupied homes in Coram, 45% heat with natural gas, 34% with heating oil, 18% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US3618157, checked 2026-10-19).
Gas leads in Coram at 45%, but 36% of homes still burn delivered oil or propane, and those 5,450 or so homes are where a heat pump pays back fastest.
Coram has 10 points less oil heat than Suffolk County as a whole, where 44% of homes burn oil, and 9 points more electric heat than the county's 9% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US36103, checked 2026-10-19).
Coram has 16,304 housing units, 2% built before 1940 and 52% before 1980, with 17% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US3618157, checked 2026-10-19).
Coram has 7 points fewer pre-1940 homes than Suffolk County as a whole (9%) and 4 points more homes built after 2000 than the county's 13% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US36103, checked 2026-10-19).
The median Coram home was built in 1979 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US3618157, checked 2026-10-19) and the median home has 5.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US3618157, checked 2026-10-19).
52% of Coram homes are single-family detached, 9% 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=160XX00US3618157, checked 2026-10-19).
31% of Coram homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US3618157, checked 2026-10-19), so beside the 52% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Coram has 28 points fewer detached houses than Suffolk County overall (80%) and 15 points more five-plus-unit buildings than the county's 8% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US36103, checked 2026-10-19).
No electric utility is on file for Coram 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 Coram address before counting it. With 18% of Coram homes already on electric heat and 81% 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 Coram is $105,220 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US3618157, 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: 7F.

That 7F figure is the Suffolk County cold-day number a Coram heat pump is sized against, so ask the installer to show the system's heating output at 7F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 45% of Coram on gas and 18% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Coram home has 5.7 rooms and was built around 1979, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
