Of the 5,929 occupied homes in Northborough, 35% heat with natural gas, 41% with heating oil, 14% with electricity and 7% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2502746820, checked 2026-10-19).
Northborough has 3 points more oil heat than Worcester County as a whole, where 38% of homes burn oil, and 6 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 Northborough at 41%, ahead of gas at 35%, 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 Northborough home was built in 1980 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2502746820, checked 2026-10-19) and the median home has 6.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2502746820, checked 2026-10-19).

Only 19% of Northborough homes are new enough to pass the whole-home rebate's weatherization check on age, and 11% date from before 1940, so most of the other 81% show it with a home energy assessment before the heat pump goes in.
75% of Northborough homes are single-family detached, 8% are in two- to four-unit buildings and 10% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2502746820, checked 2026-10-19).
With 75% detached houses and 8% in small multi-family buildings, a Northborough quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 17% of Northborough homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2502746820, checked 2026-10-19), the landlord signs the quote in many of them.
Northborough has 18 points more detached houses than Worcester County overall (57%) (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 Northborough on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
If the Northborough 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 Northborough is $153,199 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2502746820, 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 Northborough 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 5,929 occupied Northborough homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Northborough home has 6.7 rooms and was built around 1980, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
