Manchester / Milton
Milton has 4,538 residents (give or take 18) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3301748660, checked 2026-10-19), about 137 people per square mile.
Milton is about 39 miles from the Census center point for Manchester in a straight line and covers 33.05 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 Milton that is 03851, 03852 (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).
Milton is spread out at 137 people per square mile across 33.05 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 1,699 occupied homes in Milton, 1% heat with natural gas, 69% with heating oil, 2% with electricity and 14% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3301748660, checked 2026-10-19).
Heating oil is the largest single fuel in Milton at 69%, ahead of propane at 14%, 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.
Milton has 26 points more oil heat than Strafford County as a whole, where 43% of homes burn oil, and 10 points less electric heat than the county's 12% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33017, checked 2026-10-19).
Milton has 1,992 housing units, 17% built before 1940 and 50% before 1980, with 28% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3301748660, checked 2026-10-19).
Milton has 5 points more homes built after 2000 than the county's 23% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US33017, checked 2026-10-19).
The median Milton home was built in 1980 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3301748660, checked 2026-10-19) and the median home has 5.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3301748660, checked 2026-10-19).
80% of Milton homes are single-family detached, 6% 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=060XX00US3301748660, checked 2026-10-19).
With 80% detached houses and 6% in small multi-family buildings, a Milton quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 14% of Milton homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301748660, checked 2026-10-19), the landlord signs the quote in many of them.
Milton has 25 points more detached houses than Strafford County overall (55%) and 18 points fewer five-plus-unit buildings than the county's 19% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US33017, checked 2026-10-19).
Only 14% of Milton homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301748660, 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 Milton 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 Milton address before counting it. With 2% of Milton homes already on electric heat and 84% 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 Milton is $94,493 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3301748660, 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.
Heating design temperature: 0F.

That 0F figure is the Strafford County cold-day number a Milton 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 69% of the 1,699 occupied Milton homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Milton home has 5.8 rooms and was built around 1980, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
