The quote form takes a ZIP code; for Milton that is 02186 (Census 2020 ZCTA to county subdivision relationship file, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt, checked 2026-10-19).
Of the 9,094 occupied homes in Milton, 67% heat with natural gas, 22% with heating oil, 8% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502141690, checked 2026-10-19).
Milton has about the Norfolk County oil share of 23% and 10 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 Milton at 67%, but 24% of homes still burn delivered oil or propane, and those 2,183 or so homes are where a heat pump pays back fastest.
The median Milton home was built in 1945 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502141690, 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=060XX00US2502141690, checked 2026-10-19).
Milton has 9,335 housing units, 46% built before 1940 and 81% before 1980, with 9% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502141690, checked 2026-10-19).
Milton has 20 points more pre-1940 homes than Norfolk County as a whole (26%) and 6 points fewer 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). An older stock means more insulation upgrades before the heat pump goes in.
With 46% of homes built before 1940 and only 9% new enough to pass on age, the first question for a Milton house is insulation: the whole-home rebate wants proof the house is weatherized, and a no-cost home energy assessment is the usual way an older home shows it.
75% of Milton homes are single-family detached, 12% are in two- to four-unit buildings and 7% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502141690, checked 2026-10-19).
With 75% detached houses and 12% in small multi-family buildings, a Milton quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 15% of Milton homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502141690, checked 2026-10-19), the landlord signs the quote in many of them.
Milton has 18 points more detached houses than Norfolk County overall (57%) and 18 points fewer five-plus-unit buildings than the county's 25% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25021, checked 2026-10-19).
Only 15% of Milton homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502141690, 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.
Eversource Energy lists Milton 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 Milton 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 Milton is $188,529 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502141690, 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. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Norfolk 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 1F figure is the Norfolk County cold-day number a Milton 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 67% of Milton on gas and 8% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Milton house from before 1940 (46% of the 9,335 units) rarely matches a square-footage rule of thumb.
