Manchester / Candia
Candia has 4,134 residents (give or take 20) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3301509300, checked 2026-10-19), about 136 people per square mile.
Candia is about 7 miles from the Census center point for Manchester in a straight line and covers 30.343 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 Candia that is 03034 (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).
Candia is spread out at 136 people per square mile across 30.343 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 1,434 occupied homes in Candia, 0% heat with natural gas, 63% with heating oil, 4% with electricity and 24% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3301509300, checked 2026-10-19).
Heating oil is the largest single fuel in Candia at 63%, ahead of propane at 24%, 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.
Candia has 21 points more oil heat than Rockingham County as a whole, where 42% 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=050XX00US33015, checked 2026-10-19).
Candia has 1,444 housing units, 24% built before 1940 and 51% before 1980, with 15% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3301509300, checked 2026-10-19).
Candia has 12 points more pre-1940 homes than Rockingham County as a whole (12%) and 8 points fewer homes built after 2000 than the county's 23% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US33015, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Candia home was built in 1979 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3301509300, checked 2026-10-19) and the median home has 6.5 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3301509300, checked 2026-10-19).
94% of Candia homes are single-family detached, 3% 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=060XX00US3301509300, checked 2026-10-19).
With 94% detached houses and 3% in small multi-family buildings, a Candia quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 8% of Candia homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301509300, checked 2026-10-19), the landlord signs the quote in many of them.
Candia has 29 points more detached houses than Rockingham County overall (65%) and 16 points fewer five-plus-unit buildings than the county's 16% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US33015, checked 2026-10-19).
Only 8% of Candia homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301509300, 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 and New Hampshire Electric Cooperative each list Candia for electric service (New Hampshire Department of Energy, utilities by city and town, https://www.energy.nh.gov/utilities-providers/utilities-city-town, checked 2026-10-19); the bill decides the rebate path.
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 Candia address before counting it. With 4% of Candia 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 Candia is $119,737 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3301509300, 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 Rockingham County cold-day number a Candia 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 63% of the 1,434 occupied Candia homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Candia home has 6.5 rooms and was built around 1979, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
