Manchester / Gorham
Gorham has 2,682 residents (give or take 23) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3300730260, checked 2026-10-19), about 84 people per square mile.
Gorham is about 98 miles from the Census center point for Manchester in a straight line and covers 31.829 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 Gorham that is 03581 (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).
Gorham is spread out at 84 people per square mile across 31.829 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 1,389 occupied homes in Gorham, 2% heat with natural gas, 76% with heating oil, 2% with electricity and 8% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3300730260, checked 2026-10-19).
Heating oil is the largest single fuel in Gorham at 76%, ahead of propane at 8%, 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.
Gorham has 8 points more oil heat than Coos County as a whole, where 68% of homes burn oil, and 2 points less electric heat than the county's 4% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33007, checked 2026-10-19).
Gorham has 1,642 housing units, 19% built before 1940 and 75% before 1980, with 7% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3300730260, checked 2026-10-19).
Gorham has 10 points fewer pre-1940 homes than Coos County as a whole (29%) and 7 points fewer homes built after 2000 than the county's 14% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US33007, checked 2026-10-19).
The median Gorham home was built in 1971 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3300730260, checked 2026-10-19) and the median home has 4.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3300730260, checked 2026-10-19).
53% of Gorham homes are single-family detached, 13% are in two- to four-unit buildings and 11% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3300730260, checked 2026-10-19).
28% of Gorham homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3300730260, checked 2026-10-19), so beside the 53% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Gorham has 15 points fewer detached houses than Coos County overall (68%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US33007, checked 2026-10-19).
75% of Gorham homes were built before 1980 and only 7% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3300730260, 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.
Eversource lists Gorham 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 Gorham address before counting it. With 2% of Gorham homes already on electric heat and 86% 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 Gorham is $61,275 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3300730260, 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: -18F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Coos County row, 99% heating, PDF page 81 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That -18F figure is the Coos County cold-day number a Gorham heat pump is sized against, so ask the installer to show the system's heating output at -18F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 76% of the 1,389 occupied Gorham homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Gorham home has 4.9 rooms and was built around 1971, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
