Boston / Haverhill
Haverhill has 67,698 residents (give or take 63) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2500929405, checked 2026-10-19), about 2,049 people per square mile.
Haverhill is about 31 miles from the Census center point for Boston in a straight line and covers 33.036 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 Haverhill that is 01830, 01832, 01835 (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 Haverhill is $88,326 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2500929405, 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.
41% of Haverhill homes are single-family detached, 25% are in two- to four-unit buildings and 23% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2500929405, checked 2026-10-19).
37% of Haverhill homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2500929405, checked 2026-10-19), so beside the 41% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Haverhill has 9 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).
Of the 26,545 occupied homes in Haverhill, 67% heat with natural gas, 11% with heating oil, 17% with electricity and 4% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2500929405, checked 2026-10-19).
Gas leads in Haverhill at 67%, but 15% of homes still burn delivered oil or propane, and those 3,982 or so homes are where a heat pump pays back fastest.
Haverhill has 9 points less oil heat than Essex County as a whole, where 20% of homes burn oil, and the same 17% electric share (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 Haverhill on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
If the Haverhill 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).
Haverhill has 27,892 housing units, 38% built before 1940 and 63% before 1980, with 12% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2500929405, checked 2026-10-19).
Haverhill has 3 points more pre-1940 homes than Essex County as a whole (35%) (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 Haverhill home was built in 1964 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2500929405, checked 2026-10-19) and the median home has 5.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2500929405, checked 2026-10-19).
Only 12% of Haverhill homes are new enough to pass the whole-home rebate's weatherization check on age, and 38% date from before 1940, so most of the other 88% show it with a home energy assessment before the heat pump goes in.

That 1F figure is the Essex County cold-day number a Haverhill 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 Haverhill 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; a Haverhill house from before 1940 (38% of the 27,892 units) rarely matches a square-footage rule of thumb.
