Gas leads in Duxbury at 56%, but 32% of homes still burn delivered oil or propane, and those 1,962 or so homes are where a heat pump pays back fastest.
Duxbury has 5 points less oil heat than Plymouth County as a whole, where 32% of homes burn oil, and 2 points less electric heat than the county's 12% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25023, checked 2026-10-19).
Duxbury has 6,373 housing units, 15% built before 1940 and 58% before 1980, with 15% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502317895, checked 2026-10-19).
Duxbury has 6 points fewer pre-1940 homes than Plymouth County as a whole (21%) and 3 points fewer homes built after 2000 than the county's 18% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25023, checked 2026-10-19).
The median Duxbury home was built in 1976 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502317895, checked 2026-10-19) and the median home has 7.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2502317895, checked 2026-10-19).
83% of Duxbury homes are single-family detached, 2% are in two- to four-unit buildings and 12% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502317895, checked 2026-10-19).
With 83% detached houses and 2% in small multi-family buildings, a Duxbury quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 9% of Duxbury homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502317895, checked 2026-10-19), the landlord signs the quote in many of them.
Duxbury has 13 points more detached houses than Plymouth County overall (70%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25023, checked 2026-10-19).
Only 9% of Duxbury homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502317895, 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.
Only 15% of Duxbury homes are new enough to pass the whole-home rebate's weatherization check on age, and 15% date from before 1940, so most of the other 85% show it with a home energy assessment before the heat pump goes in.
Eversource Energy lists Duxbury 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 Duxbury 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 Duxbury is $176,583 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502317895, 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: 9F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Plymouth County row, 99% heating, PDF page 56 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 9F figure is the Plymouth County cold-day number a Duxbury heat pump is sized against, so ask the installer to show the system's heating output at 9F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 56% of Duxbury on gas and 10% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Duxbury home has 7.4 rooms and was built around 1976, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
