Worcester / Whitinsville
Whitinsville has 7,115 residents (give or take 733) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2579495, checked 2026-10-19), about 1,954 people per square mile.
Whitinsville is about 13 miles from the Census center point for Worcester in a straight line and covers 3.642 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 Whitinsville that is 01588 (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 Whitinsville is $96,145 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2579495, 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.
44% of Whitinsville homes are single-family detached, 25% are in two- to four-unit buildings and 10% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US2579495, checked 2026-10-19).
41% of Whitinsville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2579495, checked 2026-10-19), so beside the 44% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Whitinsville has 13 points fewer detached houses than Worcester County overall (57%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25027, checked 2026-10-19).
41% of Whitinsville homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2579495, 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 2,906 occupied homes in Whitinsville, 37% heat with natural gas, 45% with heating oil, 15% with electricity and 3% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2579495, checked 2026-10-19).
Heating oil is the largest single fuel in Whitinsville at 45%, ahead of gas at 37%, 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.
Whitinsville has 7 points more oil heat than Worcester County as a whole, where 38% of homes burn oil, and 5 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).
No electric utility is on file for Whitinsville on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
If the Whitinsville 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).
Whitinsville has 3,142 housing units, 37% built before 1940 and 60% before 1980, with 15% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2579495, checked 2026-10-19).
Whitinsville has 10 points more pre-1940 homes than Worcester County as a whole (27%) (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.
The median Whitinsville home was built in 1962 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2579495, checked 2026-10-19) and the median home has 6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US2579495, checked 2026-10-19).
Only 15% of Whitinsville homes are new enough to pass the whole-home rebate's weatherization check on age, and 37% date from before 1940, so most of the other 85% show it with a home energy assessment before the heat pump goes in.

That -2F figure is the Worcester County cold-day number a Whitinsville 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 45% of the 2,906 occupied Whitinsville homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; a Whitinsville house from before 1940 (37% of the 3,142 units) rarely matches a square-footage rule of thumb.
