Manchester / Pembroke
Pembroke has 7,438 residents (give or take 24) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US3301360020, checked 2026-10-19), about 329 people per square mile.
Pembroke is about 13 miles from the Census center point for Manchester in a straight line and covers 22.635 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 Pembroke that is 03275 (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).
Pembroke is spread out at 329 people per square mile across 22.635 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 2,808 occupied homes in Pembroke, 35% heat with natural gas, 40% with heating oil, 6% with electricity and 13% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US3301360020, checked 2026-10-19).
Heating oil is the largest single fuel in Pembroke at 40%, ahead of gas at 35%, 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.
Pembroke has 7 points more oil heat than Merrimack County as a whole, where 33% of homes burn oil, and 7 points less electric heat than the county's 13% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US33013, checked 2026-10-19).
Pembroke has 2,847 housing units, 30% built before 1940 and 63% before 1980, with 13% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3301360020, checked 2026-10-19).
Pembroke has 6 points more pre-1940 homes than Merrimack County as a whole (24%) and 7 points fewer homes built after 2000 than the county's 20% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US33013, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Pembroke home was built in 1969 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US3301360020, checked 2026-10-19) and the median home has 6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US3301360020, checked 2026-10-19).
60% of Pembroke homes are single-family detached, 17% are in two- to four-unit buildings and 12% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US3301360020, checked 2026-10-19).
33% of Pembroke homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US3301360020, checked 2026-10-19), so beside the 60% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
30% of Pembroke homes were built before 1940 and 63% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US3301360020, checked 2026-10-19), so insulation is the first sizing question: an older home leaks more heat per square foot, and the installer runs a room-by-room heat-loss calculation to size the system for what the walls and windows actually hold in, not just the floor plan.
Eversource and Unitil each list Pembroke 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 Pembroke address before counting it. With 6% of Pembroke homes already on electric heat and 88% 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 Pembroke is $89,519 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US3301360020, 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), Merrimack 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 Merrimack County cold-day number a Pembroke 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 40% of the 2,808 occupied Pembroke homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; a Pembroke house from before 1940 (30% of the 2,847 units) rarely matches a square-footage rule of thumb.
