Portland / Bowdoinham
Bowdoinham has 3,142 residents (give or take 22) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2302306365, checked 2026-10-19), about 91 people per square mile.
Bowdoinham is about 33 miles from the Census center point for Portland in a straight line and covers 34.43 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 Bowdoinham that is 04008 (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).
Bowdoinham is spread out at 91 people per square mile across 34.43 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 1,285 occupied homes in Bowdoinham, 0% heat with natural gas, 60% with heating oil, 11% with electricity and 11% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2302306365, checked 2026-10-19).
Heating oil is the largest single fuel in Bowdoinham at 60%, ahead of electricity at 11%, 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.
Bowdoinham has 7 points more oil heat than Sagadahoc County as a whole, where 53% of homes burn oil, and the same 11% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US23023, checked 2026-10-19).
Bowdoinham has 1,370 housing units, 15% built before 1940 and 38% before 1980, with 23% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2302306365, checked 2026-10-19).
Bowdoinham has 12 points fewer pre-1940 homes than Sagadahoc County as a whole (27%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US23023, checked 2026-10-19).
The median Bowdoinham home was built in 1985 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2302306365, 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=060XX00US2302306365, checked 2026-10-19).
81% of Bowdoinham homes are single-family detached, 0% 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=060XX00US2302306365, checked 2026-10-19).
With 81% detached houses and 0% in small multi-family buildings, a Bowdoinham quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 6% of Bowdoinham homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2302306365, checked 2026-10-19), the landlord signs the quote in many of them.
Bowdoinham has 6 points more detached houses than Sagadahoc County overall (75%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US23023, checked 2026-10-19).
Only 6% of Bowdoinham homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2302306365, 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.
No electric utility is on file for Bowdoinham on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Efficiency Maine whole-home heat pump rebate, run by Efficiency Maine, is a live program for Maine addresses and lists a standard figure of $3,000 (registry row 7 verified 2026-10-15, https://www.efficiencymaine.com/whole-home-heat-pump-rebates/, checked 2026-10-16); confirm eligibility for the Bowdoinham address before counting it. With 11% of Bowdoinham homes already on electric heat and 71% 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 Bowdoinham is $108,479 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2302306365, 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: -2F.

That -2F figure is the Sagadahoc County cold-day number a Bowdoinham heat pump is sized against, so ask the installer to show the system's heating output at -2F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 60% of the 1,285 occupied Bowdoinham homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Bowdoinham home has 5.8 rooms and was built around 1985, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
