Manchester / Center Harbor
Center Harbor has 955 residents (give or take 229) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3300110660, checked 2026-10-19), about 72 people per square mile.
Center Harbor is about 50 miles from the Census center point for Manchester in a straight line and covers 13.265 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 Center Harbor that is 03226 (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).
Center Harbor is spread out at 72 people per square mile across 13.265 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 409 occupied homes in Center Harbor, 2% heat with natural gas, 52% with heating oil, 6% with electricity and 17% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3300110660, checked 2026-10-19).
Heating oil is the largest single fuel in Center Harbor at 52%, ahead of propane at 17%, 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.
Center Harbor has about the Belknap County oil share of 50% and 3 points less electric heat than the county's 9% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33001, checked 2026-10-19).

The median Center Harbor home was built in 1982 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3300110660, 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=060XX00US3300110660, checked 2026-10-19).
90% of Center Harbor homes are single-family detached, 2% are in two- to four-unit buildings and 0% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3300110660, checked 2026-10-19).
With 90% detached houses and 2% in small multi-family buildings, a Center Harbor quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 9% of Center Harbor homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3300110660, checked 2026-10-19), the landlord signs the quote in many of them.
Center Harbor has 16 points more detached houses than Belknap County overall (74%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US33001, checked 2026-10-19).
Only 9% of Center Harbor homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3300110660, 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.
New Hampshire Electric Cooperative lists Center Harbor 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 Center Harbor address before counting it. With 6% of Center Harbor homes already on electric heat and 71% 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 Center Harbor is $104,313 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3300110660, 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 Belknap County cold-day number a Center Harbor 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 what happens to the oil tank, since 52% of the 409 occupied Center Harbor homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Center Harbor home has 5.9 rooms and was built around 1982, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
