Fuel mix

Of the 39,611 occupied homes in Smithtown, 50% heat with natural gas, 39% 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=060XX00US3610368000, checked 2026-10-19).

Gas leads in Smithtown at 50%, but 41% of homes still burn delivered oil or propane, and those 16,241 or so homes are where a heat pump pays back fastest.

Smithtown has 5 points less oil heat than Suffolk County as a whole, where 44% of homes burn oil, and 2 points less 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).

Housing stock

Smithtown has 40,714 housing units, 5% built before 1940 and 74% before 1980, with 8% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3610368000, checked 2026-10-19).

Smithtown has 4 points fewer pre-1940 homes than Suffolk County as a whole (9%) and 5 points fewer 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 Smithtown home was built in 1968 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3610368000, checked 2026-10-19) and the median home has 7.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3610368000, checked 2026-10-19).

86% of Smithtown homes are single-family detached, 2% are in two- to four-unit buildings and 6% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3610368000, checked 2026-10-19).

With 86% detached houses and 2% in small multi-family buildings, a Smithtown quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 11% of Smithtown homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3610368000, checked 2026-10-19), the landlord signs the quote in many of them.

Smithtown has 6 points more detached houses than Suffolk County overall (80%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US36103, checked 2026-10-19).

Only 11% of Smithtown homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3610368000, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.

74% of Smithtown homes were built before 1980 and only 8% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3610368000, 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.

Rebate path

No electric utility is on file for Smithtown 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 Smithtown address before counting it. With 7% of Smithtown homes already on electric heat and 91% 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 Smithtown is $152,636 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3610368000, 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.

Cold-day number

Heating design temperature: 7F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Suffolk 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 7F figure is the Suffolk County cold-day number a Smithtown 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.

Next step

Ask whether the quote is whole-home or partial-home, because with 50% of Smithtown on gas and 7% already electric the two paths carry different rebate figures and different sizing.

Ask for the heat-loss calculation room by room; the median Smithtown home has 7.2 rooms and was built around 1968, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
