Worcester / Leominster
Leominster has 43,909 residents (give or take 36) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2502735075, checked 2026-10-19), about 1,523 people per square mile.
Leominster is about 17 miles from the Census center point for Worcester in a straight line and covers 28.823 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 Leominster that is 01453 (Census 2020 ZCTA to county subdivision and ZCTA to place relationship files, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt and https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_place20_natl.txt, checked 2026-10-19).
Median household income in Leominster is $83,816 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502735075, 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.
47% of Leominster homes are single-family detached, 20% are in two- to four-unit buildings and 27% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502735075, checked 2026-10-19).
38% of Leominster homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502735075, 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.
Leominster has 10 points fewer detached houses than Worcester County overall (57%) and 10 points more five-plus-unit buildings than the county's 17% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25027, checked 2026-10-19).
Of the 18,483 occupied homes in Leominster, 34% heat with natural gas, 36% with heating oil, 24% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502735075, checked 2026-10-19).
Heating oil is the largest single fuel in Leominster at 36%, ahead of gas at 34%, so the usual job here is an oil boiler or furnace coming out and a cold-climate heat pump going in, with the oil tank removed.
Leominster has about the Worcester County oil share of 38% and 4 points more electric heat than the county's 20% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25027, checked 2026-10-19).
No electric utility is on file for Leominster on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
If the Leominster 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).
Leominster has 19,255 housing units, 23% built before 1940 and 64% before 1980, with 12% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502735075, checked 2026-10-19).
Leominster has 4 points fewer pre-1940 homes than Worcester County as a whole (27%) and 3 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=050XX00US25027, checked 2026-10-19).
The median Leominster home was built in 1967 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502735075, 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=060XX00US2502735075, checked 2026-10-19).
Only 12% of Leominster homes are new enough to pass the whole-home rebate's weatherization check on age, and 23% date from before 1940, so most of the other 88% show it with a home energy assessment before the heat pump goes in.

That -2F figure is the Worcester County cold-day number a Leominster heat pump is sized against, so ask the installer to show the system's heating output at -2F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 36% of the 18,483 occupied Leominster homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Leominster home has 5.2 rooms and was built around 1967, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
