Boston / Quincy
Quincy has 102,114 residents (give or take 45) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2502155745, checked 2026-10-19), about 6,161 people per square mile.
Quincy is about 5 miles from the Census center point for Boston in a straight line and covers 16.573 square miles of land (Census 2024 Gazetteer internal points and land area, https://www2.census.gov/geo/docs/maps-data/data/gazetteer/2024_Gazetteer/, checked 2026-10-19).
The quote form takes a ZIP code; for Quincy that is 02169, 02170, 02171 (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).
Median household income in Quincy is $98,882 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502155745, 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.
6,161 people per square mile puts Quincy in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
33% of Quincy homes are single-family detached, 21% are in two- to four-unit buildings and 40% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502155745, checked 2026-10-19).
With 40% of Quincy homes in buildings of five or more units and 33% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 55% of Quincy homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502155745, checked 2026-10-19), the landlord signs the quote in many of them.
Quincy has 24 points fewer detached houses than Norfolk County overall (57%) and 15 points more 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).
55% of Quincy homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502155745, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
Of the 45,285 occupied homes in Quincy, 54% heat with natural gas, 12% with heating oil, 30% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502155745, checked 2026-10-19).
Gas leads in Quincy at 54%, but 15% of homes still burn delivered oil or propane, and those 6,793 or so homes are where a heat pump pays back fastest.
Quincy has 11 points less oil heat than Norfolk County as a whole, where 23% of homes burn oil, and 12 points more 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).
Eversource Energy lists Quincy 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 Quincy 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).
Quincy has 48,072 housing units, 37% built before 1940 and 68% before 1980, with 17% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502155745, checked 2026-10-19).
Quincy has 11 points more pre-1940 homes than Norfolk County as a whole (26%) (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.
The median Quincy home was built in 1958 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502155745, checked 2026-10-19) and the median home has 4.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2502155745, checked 2026-10-19).
Only 17% of Quincy homes are new enough to pass the whole-home rebate's weatherization check on age, and 37% date from before 1940, so most of the other 83% show it with a home energy assessment before the heat pump goes in.

That 1F figure is the Norfolk County cold-day number a Quincy 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 54% of Quincy on gas and 30% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Quincy house from before 1940 (37% of the 48,072 units) rarely matches a square-footage rule of thumb.
