Manchester / Brookline
Brookline is about 20 miles from the Census center point for Manchester in a straight line and covers 19.835 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).
Brookline has 5,736 residents (give or take 21) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3301108100, checked 2026-10-19), about 289 people per square mile.
The quote form takes a ZIP code; for Brookline that is 03033 (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).
Brookline is spread out at 289 people per square mile across 19.835 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 1,831 occupied homes in Brookline, 1% heat with natural gas, 39% with heating oil, 4% with electricity and 47% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3301108100, checked 2026-10-19).
Brookline has 10 points more oil heat than Hillsborough County as a whole, where 29% of homes burn oil, and 8 points less electric heat than the county's 12% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33011, checked 2026-10-19).
Propane leads in Brookline at 47%, ahead of oil at 39%, and a propane home is the clearest heat pump case on this door because delivered fuel is priced per gallon with no pipe to fall back on.
The median Brookline home was built in 1993 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3301108100, checked 2026-10-19) and the median home has 7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3301108100, checked 2026-10-19).
Brookline has 1,880 housing units, 12% built before 1940 and 25% before 1980, with 26% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3301108100, checked 2026-10-19).
Brookline has 6 points fewer pre-1940 homes than Hillsborough County as a whole (18%) and 9 points more homes built after 2000 than the county's 17% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US33011, checked 2026-10-19).
92% of Brookline homes are single-family detached, 3% are in two- to four-unit buildings and 1% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3301108100, checked 2026-10-19).
With 92% detached houses and 3% in small multi-family buildings, a Brookline quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 5% of Brookline homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301108100, checked 2026-10-19), the landlord signs the quote in many of them.
Brookline has 35 points more detached houses than Hillsborough County overall (57%) and 20 points fewer five-plus-unit buildings than the county's 21% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US33011, checked 2026-10-19).
Only 5% of Brookline homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301108100, checked 2026-10-19), so nearly every quote here is the resident talking to the installer directly, and the rebate goes to the person living in the house.
Eversource lists Brookline among the New Hampshire communities it serves for electricity (New Hampshire Department of Energy, utilities by city and town, https://www.energy.nh.gov/utilities-providers/utilities-city-town, checked 2026-10-19).
NHSaves air source heat pump rebate, run by NHSaves (Eversource, Liberty, Unitil), is a live program for New Hampshire addresses and lists a standard figure of $250 (registry row 6 verified 2026-10-14, https://nhsaves.com/residential/electric-heating-cooling-equipment/, checked 2026-10-16); confirm eligibility for the Brookline address before counting it. With 4% of Brookline homes already on electric heat and 87% 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 Brookline is $171,046 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3301108100, 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.

That 0F figure is the Hillsborough County cold-day number a Brookline heat pump is sized against, so ask the installer to show the system's heating output at 0F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Brookline home has 7 rooms and was built around 1993, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
