Of the 12,370 occupied homes in Franklin, 60% heat with natural gas, 20% with heating oil, 16% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502125172, checked 2026-10-19).
Franklin has 3 points less oil heat than Norfolk County as a whole, where 23% of homes burn oil, and 2 points less electric heat than the county's 18% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25021, checked 2026-10-19).
Gas leads in Franklin at 60%, but 23% of homes still burn delivered oil or propane, and those 2,845 or so homes are where a heat pump pays back fastest.
The median Franklin home was built in 1985 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502125172, checked 2026-10-19) and the median home has 6.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2502125172, checked 2026-10-19).
Franklin has 13,011 housing units, 14% built before 1940 and 41% before 1980, with 22% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502125172, checked 2026-10-19).
Franklin has 12 points fewer pre-1940 homes than Norfolk County as a whole (26%) and 7 points more homes built after 2000 than the county's 15% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25021, checked 2026-10-19).
Only 22% of Franklin homes are new enough to pass the whole-home rebate's weatherization check on age, and 14% date from before 1940, so most of the other 78% show it with a home energy assessment before the heat pump goes in.
62% of Franklin homes are single-family detached, 9% are in two- to four-unit buildings and 18% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502125172, checked 2026-10-19).
22% of Franklin homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502125172, checked 2026-10-19), so beside the 62% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Franklin has 5 points more detached houses than Norfolk County overall (57%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25021, checked 2026-10-19).
Eversource Energy lists Franklin among the Massachusetts communities it serves for electricity (Eversource Energy communities we serve, https://www.eversource.com/residential/services/communities-we-serve, checked 2026-10-19).
For a Franklin address billed by Eversource Energy, the Mass Save whole-home heat pump rebate is $2,650 per ton up to $8,500, and the partial-home rebate is $1,125 per ton up to $8,500; for projects installed on or after January 1, 2027, the whole-home figure drops to $2,350 per ton capped at $7,500 (Mass Save air-source heat pump rebates, https://www.masssave.com/residential/rebates-offers-services/heating-and-cooling/heat-pumps/air-source-heat-pumps, checked 2026-10-19).
Median household income in Franklin is $145,773 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502125172, checked 2026-10-19); Mass Save's enhanced heat pump incentives are income-based and decided household by household, so the town median only hints at how many neighbors qualify.
Heating design temperature: 1F.

That 1F figure is the Norfolk County cold-day number a Franklin heat pump is sized against, so ask the installer to show the system's heating output at 1F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 60% of Franklin on gas and 16% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Franklin home has 6.4 rooms and was built around 1985, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
