Portland / Blue Hill
Blue Hill has 2,813 residents (give or take 15) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2300905700, checked 2026-10-19), about 45 people per square mile.
Blue Hill is about 98 miles from the Census center point for Portland in a straight line and covers 62.478 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 Blue Hill that is 04614 (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).
Blue Hill is spread out at 45 people per square mile across 62.478 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 1,308 occupied homes in Blue Hill, 0% heat with natural gas, 33% with heating oil, 23% with electricity and 24% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2300905700, checked 2026-10-19).
Heating oil is the largest single fuel in Blue Hill at 33%, ahead of propane at 24%, 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.
Blue Hill has 18 points less oil heat than Hancock County as a whole, where 51% of homes burn oil, and 12 points more electric heat than the county's 11% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US23009, checked 2026-10-19).
Blue Hill has 1,962 housing units, 18% built before 1940 and 38% before 1980, with 32% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2300905700, checked 2026-10-19).
Blue Hill has 4 points fewer pre-1940 homes than Hancock County as a whole (22%) and 7 points more homes built after 2000 than the county's 25% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US23009, checked 2026-10-19).
The median Blue Hill home was built in 1992 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2300905700, checked 2026-10-19) and the median home has 5.3 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2300905700, checked 2026-10-19).
79% of Blue Hill homes are single-family detached, 7% are in two- to four-unit buildings and 8% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2300905700, checked 2026-10-19).
With 79% detached houses and 7% in small multi-family buildings, a Blue Hill quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 20% of Blue Hill homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2300905700, checked 2026-10-19), the landlord signs the quote in many of them.
No electric utility is on file for Blue Hill 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 Blue Hill address before counting it. With 23% of Blue Hill homes already on electric heat and 57% 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 Blue Hill is $80,377 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2300905700, 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: -5F.

That -5F figure is the Hancock County cold-day number a Blue Hill heat pump is sized against, so ask the installer to show the system's heating output at -5F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 33% of the 1,308 occupied Blue Hill homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Blue Hill home has 5.3 rooms and was built around 1992, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
