Worcester / South Hadley
South Hadley has 17,754 residents (give or take 22) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2501564145, checked 2026-10-19), about 1,002 people per square mile.
South Hadley is about 40 miles from the Census center point for Worcester in a straight line and covers 17.713 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 South Hadley that is 01075 (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 7,210 occupied homes in South Hadley, 51% heat with natural gas, 22% with heating oil, 23% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2501564145, checked 2026-10-19).
Gas leads in South Hadley at 51%, but 24% of homes still burn delivered oil or propane, and those 1,730 or so homes are where a heat pump pays back fastest.
South Hadley has 8 points less oil heat than Hampshire County as a whole, where 30% of homes burn oil, and 2 points more electric heat than the county's 21% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25015, checked 2026-10-19).
South Hadley has 7,511 housing units, 18% built before 1940 and 68% before 1980, with 11% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2501564145, checked 2026-10-19).
South Hadley has 9 points fewer pre-1940 homes than Hampshire County as a whole (27%) and 3 points fewer homes built after 2000 than the county's 14% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25015, checked 2026-10-19).
The median South Hadley home was built in 1961 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2501564145, 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=060XX00US2501564145, checked 2026-10-19).
67% of South Hadley homes are single-family detached, 12% are in two- to four-unit buildings and 12% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2501564145, checked 2026-10-19).
23% of South Hadley homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2501564145, checked 2026-10-19), so beside the 67% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
South Hadley has 8 points more detached houses than Hampshire County overall (59%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25015, checked 2026-10-19).
68% of South Hadley homes were built before 1980 and only 11% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2501564145, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
South Hadley is also on the state table of towns served by a municipal light plant, South Hadley Electric Light Department (Massachusetts municipally-owned electric companies, https://www.mass.gov/info-details/massachusetts-municipally-owned-electric-companies, checked 2026-10-19).
Mass Save heat pump rebates are for electric accounts with Cape Light Compact, Eversource, National Grid or Unitil, so a South Hadley home billed by South Hadley Electric Light Department asks the plant for its heat pump rebate instead.
Mass Save whole-home heat pump rebate, run by Mass Save, is a live program for Massachusetts addresses and publishes its terms without one headline figure (registry row 1 verified 2026-10-14, https://www.masssave.com/residential/rebates-and-incentives/heating-and-cooling/heat-pumps, checked 2026-10-16); confirm eligibility for the South Hadley address before counting it. With 23% of South Hadley homes already on electric heat and 75% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Median household income in South Hadley is $93,910 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2501564145, checked 2026-10-19); many state and utility heat pump rebate programs set higher incentive tiers for income-qualifying households, so the household income on the application, not the town median, decides which level applies.
Heating design temperature: -3F.

That -3F figure is the Hampshire County cold-day number a South Hadley heat pump is sized against, so ask the installer to show the system's heating output at -3F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 51% of South Hadley on gas and 23% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median South Hadley home has 5.5 rooms and was built around 1961, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
