Manchester / Manchester
Manchester has 115,643 residents (give or take 48) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3301145140, checked 2026-10-19), about 3,496 people per square mile.
Manchester is the city this door is named for; it covers 33.074 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 Manchester that is 03101, 03102, 03103, 03104, 03109 (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).
Median household income in Manchester is $81,007 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3301145140, 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.
3,496 people per square mile puts Manchester in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
36% of Manchester homes are single-family detached, 26% are in two- to four-unit buildings and 33% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3301145140, checked 2026-10-19).
51% of Manchester homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301145140, checked 2026-10-19), so beside the 36% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Manchester has 21 points fewer detached houses than Hillsborough County overall (57%) and 12 points more 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).
51% of Manchester homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301145140, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
Of the 49,162 occupied homes in Manchester, 50% heat with natural gas, 26% with heating oil, 17% with electricity and 5% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3301145140, checked 2026-10-19).
Gas leads in Manchester at 50%, but 30% of homes still burn delivered oil or propane, and those 14,749 or so homes are where a heat pump pays back fastest.
Manchester has 3 points less oil heat than Hillsborough County as a whole, where 29% of homes burn oil, and 5 points more 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).
Eversource lists Manchester 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 Manchester address before counting it. With 17% of Manchester homes already on electric heat and 81% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Manchester has 52,108 housing units, 28% built before 1940 and 65% before 1980, with 12% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3301145140, checked 2026-10-19).
Manchester has 10 points more pre-1940 homes than Hillsborough County as a whole (18%) and 5 points fewer 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). An older stock means more insulation upgrades before the heat pump goes in.
The median Manchester home was built in 1966 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3301145140, checked 2026-10-19) and the median home has 5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3301145140, checked 2026-10-19).
65% of Manchester homes were built before 1980 and only 12% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3301145140, 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.
Heating design temperature: 0F.

That 0F figure is the Hillsborough County cold-day number a Manchester 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 whether the quote is whole-home or partial-home, because with 50% of Manchester on gas and 17% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Manchester home has 5 rooms and was built around 1966, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
