Randolph has 34,878 residents (give or take 36) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2502156000, checked 2026-10-19), about 3,548 people per square mile.
The quote form takes a ZIP code; for Randolph that is 02368 (Census 2020 ZCTA to county subdivision relationship file, ZIP areas at least 20% inside the town, https://www2.census.gov/geo/docs/maps-data/data/rel2020/zcta520/tab20_zcta520_cousub20_natl.txt, checked 2026-10-19).
3,548 people per square mile puts Randolph in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 12,747 occupied homes in Randolph, 55% heat with natural gas, 21% with heating oil, 19% with electricity and 4% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502156000, checked 2026-10-19).
Randolph has about the Norfolk County oil share of 23% and 1 points more electric heat than the county's 18% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US25021, checked 2026-10-19).
Gas leads in Randolph at 55%, but 25% of homes still burn delivered oil or propane, and those 3,187 or so homes are where a heat pump pays back fastest.
The median Randolph home was built in 1966 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502156000, checked 2026-10-19) and the median home has 5.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2502156000, checked 2026-10-19).
Randolph has 13,080 housing units, 14% built before 1940 and 70% before 1980, with 12% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2502156000, checked 2026-10-19).
Randolph has 12 points fewer pre-1940 homes than Norfolk County as a whole (26%) and 3 points fewer homes built after 2000 than the county's 15% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US25021, checked 2026-10-19).
Only 12% of Randolph homes are new enough to pass the whole-home rebate's weatherization check on age, and 14% date from before 1940, so most of the other 88% show it with a home energy assessment before the heat pump goes in.
63% of Randolph homes are single-family detached, 8% are in two- to four-unit buildings and 19% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502156000, checked 2026-10-19).
29% of Randolph homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502156000, checked 2026-10-19), so beside the 63% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Randolph has 6 points more detached houses than Norfolk County overall (57%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US25021, checked 2026-10-19).
No electric utility is on file for Randolph on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
If the Randolph 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 Randolph is $109,573 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502156000, 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: 1F.

That 1F figure is the Norfolk County cold-day number a Randolph heat pump is sized against, so ask the installer to show the system's heating output at 1F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 55% of Randolph on gas and 19% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Randolph home has 5.9 rooms and was built around 1966, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
