Boston / Woburn
Woburn has 41,939 residents (give or take 26) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2501781035, checked 2026-10-19), about 3,315 people per square mile.
Woburn is about 12 miles from the Census center point for Boston in a straight line and covers 12.651 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 Woburn that is 01801 (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 Woburn is $111,185 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2501781035, 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.
3,315 people per square mile puts Woburn in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
47% of Woburn homes are single-family detached, 19% are in two- to four-unit buildings and 25% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2501781035, checked 2026-10-19).
44% of Woburn homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2501781035, checked 2026-10-19), so beside the 47% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
44% of Woburn homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2501781035, 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 16,432 occupied homes in Woburn, 51% heat with natural gas, 29% with heating oil, 17% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2501781035, checked 2026-10-19).
Gas leads in Woburn at 51%, but 32% of homes still burn delivered oil or propane, and those 5,258 or so homes are where a heat pump pays back fastest.
Woburn has 11 points more oil heat than Middlesex County as a whole, where 18% of homes burn oil, and 1 points less electric heat than the county's 18% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25017, checked 2026-10-19).
Eversource Energy lists Woburn 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 Woburn 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).
Woburn has 17,045 housing units, 19% built before 1940 and 63% before 1980, with 14% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2501781035, checked 2026-10-19).
Woburn has 13 points fewer pre-1940 homes than Middlesex County as a whole (32%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25017, checked 2026-10-19).
The median Woburn home was built in 1968 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2501781035, checked 2026-10-19) and the median home has 5.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2501781035, checked 2026-10-19).
Only 14% of Woburn homes are new enough to pass the whole-home rebate's weatherization check on age, and 19% date from before 1940, so most of the other 86% show it with a home energy assessment before the heat pump goes in.

That 1F figure is the Middlesex County cold-day number a Woburn 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 51% of Woburn on gas and 17% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Woburn home has 5.4 rooms and was built around 1968, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
