Worcester / Spencer
Spencer is about 10 miles from the Census center point for Worcester in a straight line and covers 32.851 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).
Spencer has 12,008 residents (give or take 28) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2502766105, checked 2026-10-19), about 366 people per square mile.
The quote form takes a ZIP code; for Spencer that is 01562 (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).
Spencer is spread out at 366 people per square mile across 32.851 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 5,201 occupied homes in Spencer, 19% heat with natural gas, 41% with heating oil, 29% with electricity and 7% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502766105, checked 2026-10-19).
Spencer has 3 points more oil heat than Worcester County as a whole, where 38% of homes burn oil, and 9 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).
Heating oil is the largest single fuel in Spencer at 41%, ahead of electricity at 29%, 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 Spencer home was built in 1968 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502766105, 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=060XX00US2502766105, checked 2026-10-19).
Spencer has 5,695 housing units, 29% built before 1940 and 68% before 1980, with 13% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502766105, checked 2026-10-19).
Spencer tracks Worcester County on housing age, with the county at 27% pre-1940 and 15% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25027, checked 2026-10-19).
Only 13% of Spencer homes are new enough to pass the whole-home rebate's weatherization check on age, and 29% date from before 1940, so most of the other 87% show it with a home energy assessment before the heat pump goes in.
59% of Spencer homes are single-family detached, 25% are in two- to four-unit buildings and 14% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502766105, checked 2026-10-19).
37% of Spencer homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502766105, checked 2026-10-19), so beside the 59% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
No electric utility is on file for Spencer on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
If the Spencer 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 Spencer is $80,533 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502766105, 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 Spencer 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 41% of the 5,201 occupied Spencer homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Spencer home has 5.5 rooms and was built around 1968, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
