Boston / Lawrence
Lawrence has 88,736 residents (give or take 36) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2500934550, checked 2026-10-19), about 12,805 people per square mile.
Lawrence is about 26 miles from the Census center point for Boston in a straight line and covers 6.93 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 Lawrence that is 01840, 01841, 01843 (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 Lawrence is $60,433 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2500934550, 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.
At 12,805 people per square mile, Lawrence is dense enough that noise setback rules and outdoor-unit placement on a small lot are the first questions the installer works through.
19% of Lawrence homes are single-family detached, 44% are in two- to four-unit buildings and 29% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2500934550, checked 2026-10-19).
A two- or three-family building is the common Lawrence case at 44% of the stock against 19% detached houses, and each unit usually gets its own small outdoor unit and its own rebate account rather than one big system for the building. With 72% of Lawrence homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2500934550, checked 2026-10-19), the landlord signs the quote in many of them.
Lawrence has 31 points fewer detached houses than Essex County overall (50%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25009, checked 2026-10-19).
With 72% of Lawrence homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2500934550, checked 2026-10-19), most heat pump quotes here are landlord-driven: the landlord signs the contract and picks the equipment, and the tenant sees the lower bill.
Of the 31,142 occupied homes in Lawrence, 70% heat with natural gas, 5% with heating oil, 22% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2500934550, checked 2026-10-19).
Gas heats 70% of Lawrence against electricity at 22%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
Lawrence has 15 points less oil heat than Essex County as a whole, where 20% of homes burn oil, and 5 points more electric heat than the county's 17% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25009, checked 2026-10-19).
No electric utility is on file for Lawrence on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
If the Lawrence electric bill comes from one of the Mass Save sponsors (Cape Light Compact, Eversource, National Grid, Unitil), the 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).
Lawrence has 31,845 housing units, 44% built before 1940 and 77% before 1980, with 10% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2500934550, checked 2026-10-19).
Lawrence has 9 points more pre-1940 homes than Essex County as a whole (35%) and 3 points fewer homes built after 2000 than the county's 13% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25009, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Lawrence home was built in 1950 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2500934550, checked 2026-10-19) and the median home has 4.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2500934550, checked 2026-10-19).
With 44% of homes built before 1940 and only 10% new enough to pass on age, the first question for a Lawrence 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.

That 1F figure is the Essex County cold-day number a Lawrence 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 70% of Lawrence on gas and 22% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; a Lawrence house from before 1940 (44% of the 31,845 units) rarely matches a square-footage rule of thumb.
