Worcester / Athol
Athol is about 30 miles from the Census center point for Worcester in a straight line and covers 32.297 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).
Athol has 12,011 residents (give or take 63) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2502702480, checked 2026-10-19), about 372 people per square mile.
The quote form takes a ZIP code; for Athol that is 01331 (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).
Athol is spread out at 372 people per square mile across 32.297 square miles of land, so a long refrigerant line run between the outdoor unit and the farthest indoor head is the sizing question an installer checks first.
Of the 4,704 occupied homes in Athol, 3% heat with natural gas, 72% with heating oil, 10% with electricity and 7% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502702480, checked 2026-10-19).
Athol has 34 points more oil heat than Worcester County as a whole, where 38% of homes burn oil, and 10 points less 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).
Heating oil is the largest single fuel in Athol at 72%, ahead of electricity at 10%, 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.
The median Athol home was built in 1953 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502702480, checked 2026-10-19) and the median home has 5.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2502702480, checked 2026-10-19).
Athol has 5,135 housing units, 39% built before 1940 and 74% before 1980, with 11% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502702480, checked 2026-10-19).
Athol has 12 points more pre-1940 homes than Worcester County as a whole (27%) and 4 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). An older stock means more insulation upgrades before the heat pump goes in.
Only 11% of Athol homes are new enough to pass the whole-home rebate's weatherization check on age, and 39% date from before 1940, so most of the other 89% show it with a home energy assessment before the heat pump goes in.
68% of Athol homes are single-family detached, 21% are in two- to four-unit buildings and 7% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502702480, checked 2026-10-19).
28% of Athol homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502702480, checked 2026-10-19), so beside the 68% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Athol has 11 points more detached houses than Worcester County overall (57%) and 10 points fewer 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).
No electric utility is on file for Athol on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
If the Athol 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).
Median household income in Athol is $69,316 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502702480, 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.
Heating design temperature: -2F.

That -2F figure is the Worcester County cold-day number a Athol 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 72% of the 4,704 occupied Athol homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; a Athol house from before 1940 (39% of the 5,135 units) rarely matches a square-footage rule of thumb.
