Worcester / Dudley
Dudley is about 16 miles from the Census center point for Worcester in a straight line and covers 20.832 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).
Dudley has 11,929 residents (give or take 17) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2502717685, checked 2026-10-19), about 573 people per square mile.
The quote form takes a ZIP code; for Dudley that is 01571 (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).
Of the 4,375 occupied homes in Dudley, 18% heat with natural gas, 53% with heating oil, 20% with electricity and 4% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502717685, checked 2026-10-19).
Dudley has 15 points more oil heat than Worcester County as a whole, where 38% of homes burn oil, and the same 20% electric share (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 Dudley at 53%, ahead of electricity at 20%, 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 Dudley home was built in 1967 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502717685, checked 2026-10-19) and the median home has 5.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2502717685, checked 2026-10-19).
Dudley has 4,474 housing units, 24% built before 1940 and 67% before 1980, with 13% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502717685, checked 2026-10-19).
Dudley has 3 points fewer 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).
Only 13% of Dudley homes are new enough to pass the whole-home rebate's weatherization check on age, and 24% date from before 1940, so most of the other 87% show it with a home energy assessment before the heat pump goes in.
70% of Dudley homes are single-family detached, 21% are in two- to four-unit buildings and 6% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502717685, checked 2026-10-19).
With 70% detached houses and 21% in small multi-family buildings, a Dudley quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 27% of Dudley homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502717685, checked 2026-10-19), the landlord signs the quote in many of them.
Dudley has 13 points more detached houses than Worcester County overall (57%) and 11 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 Dudley on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
If the Dudley 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 Dudley is $84,604 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502717685, 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 Dudley 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 53% of the 4,375 occupied Dudley homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Dudley home has 5.8 rooms and was built around 1967, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
