Manchester / Swanzey
Swanzey has 7,398 residents (give or take 24) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3300575700, checked 2026-10-19), about 164 people per square mile.
Swanzey is about 44 miles from the Census center point for Manchester in a straight line and covers 44.975 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 Swanzey that is 03446 (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).
Swanzey is spread out at 164 people per square mile across 44.975 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 3,154 occupied homes in Swanzey, 4% heat with natural gas, 58% with heating oil, 9% with electricity and 17% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3300575700, checked 2026-10-19).
Heating oil is the largest single fuel in Swanzey at 58%, 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.
Swanzey has about the Cheshire County oil share of 57% and 1 points less electric heat than the county's 10% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33005, checked 2026-10-19).
Swanzey has 3,334 housing units, 20% built before 1940 and 53% before 1980, with 22% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3300575700, checked 2026-10-19).
Swanzey has 7 points fewer pre-1940 homes than Cheshire County as a whole (27%) and 6 points more homes built after 2000 than the county's 16% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US33005, checked 2026-10-19).
The median Swanzey home was built in 1978 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3300575700, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3300575700, checked 2026-10-19).
66% of Swanzey homes are single-family detached, 6% are in two- to four-unit buildings and 13% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3300575700, checked 2026-10-19).
28% of Swanzey homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3300575700, checked 2026-10-19), so beside the 66% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
No electric utility is on file for Swanzey 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 Swanzey address before counting it. With 9% of Swanzey homes already on electric heat and 79% 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 Swanzey is $81,595 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3300575700, 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), Cheshire 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 Cheshire County cold-day number a Swanzey 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 58% of the 3,154 occupied Swanzey homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Swanzey home has 5.6 rooms and was built around 1978, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
