Worcester / Berlin
Berlin is about 12 miles from the Census center point for Worcester in a straight line and covers 12.972 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).
Berlin has 3,378 residents (give or take 15) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2502705490, checked 2026-10-19), about 260 people per square mile.
The quote form takes a ZIP code; for Berlin that is 01503 (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).
Berlin is spread out at 260 people per square mile across 12.972 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 1,447 occupied homes in Berlin, 28% heat with natural gas, 47% with heating oil, 13% with electricity and 7% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502705490, checked 2026-10-19).
Berlin has 9 points more oil heat than Worcester County as a whole, where 38% of homes burn oil, and 7 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 Berlin at 47%, ahead of gas at 28%, 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 Berlin home was built in 1992 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502705490, checked 2026-10-19) and the median home has 6.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2502705490, checked 2026-10-19).
Berlin has 1,495 housing units, 22% built before 1940 and 43% before 1980, with 42% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502705490, checked 2026-10-19).
Berlin has 5 points fewer pre-1940 homes than Worcester County as a whole (27%) and 27 points more 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).
With 42% of the housing built in 2000 or later, many Berlin homes clear the whole-home rebate's weatherization check on age alone, since a home built during or after 2000 counts as sufficiently weatherized under the program terms, and the other 58% show it with a home energy assessment.
53% of Berlin homes are single-family detached, 13% 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=060XX00US2502705490, checked 2026-10-19).
23% of Berlin homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502705490, checked 2026-10-19), so beside the 53% 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 Berlin on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
If the Berlin 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 Berlin is $121,336 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502705490, 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 Berlin 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 47% of the 1,447 occupied Berlin homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Berlin home has 6.3 rooms and was built around 1992, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
