Manchester / Sunapee
Sunapee has 3,416 residents (give or take 27) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3301975060, checked 2026-10-19), about 162 people per square mile.
Sunapee is about 43 miles from the Census center point for Manchester in a straight line and covers 21.053 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 Sunapee that is 03751, 03782 (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).
Sunapee is spread out at 162 people per square mile across 21.053 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 1,399 occupied homes in Sunapee, 8% heat with natural gas, 48% with heating oil, 2% with electricity and 26% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3301975060, checked 2026-10-19).
Heating oil is the largest single fuel in Sunapee at 48%, ahead of propane at 26%, 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.
Sunapee has about the Sullivan County oil share of 50% and 3 points less electric heat than the county's 5% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33019, checked 2026-10-19).
Sunapee has 2,581 housing units, 23% built before 1940 and 59% before 1980, with 16% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3301975060, checked 2026-10-19).
Sunapee tracks Sullivan County on housing age, with the county at 24% pre-1940 and 14% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US33019, checked 2026-10-19).
The median Sunapee home was built in 1975 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3301975060, 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=060XX00US3301975060, checked 2026-10-19).
85% of Sunapee homes are single-family detached, 5% are in two- to four-unit buildings and 5% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3301975060, checked 2026-10-19).
With 85% detached houses and 5% in small multi-family buildings, a Sunapee quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 24% of Sunapee homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301975060, checked 2026-10-19), the landlord signs the quote in many of them.
Sunapee has 11 points more detached houses than Sullivan County overall (74%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US33019, checked 2026-10-19).
No electric utility is on file for Sunapee on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
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 Sunapee address before counting it. With 2% of Sunapee homes already on electric heat and 82% 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 Sunapee is $101,393 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3301975060, 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: -4F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Sullivan 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 -4F figure is the Sullivan County cold-day number a Sunapee heat pump is sized against, so ask the installer to show the system's heating output at -4F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 48% of the 1,399 occupied Sunapee homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Sunapee home has 5.9 rooms and was built around 1975, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
