Portland / Norway
Norway has 5,228 residents (give or take 24) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2301754000, checked 2026-10-19), about 116 people per square mile.
Norway is about 46 miles from the Census center point for Portland in a straight line and covers 45.041 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 Norway that is 04268 (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).
Norway is spread out at 116 people per square mile across 45.041 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 2,164 occupied homes in Norway, 4% heat with natural gas, 67% with heating oil, 12% with electricity and 6% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2301754000, checked 2026-10-19).
Heating oil is the largest single fuel in Norway at 67%, ahead of electricity at 12%, 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.
Norway has 9 points more oil heat than Oxford County as a whole, where 58% of homes burn oil, and 4 points more electric heat than the county's 8% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US23017, checked 2026-10-19).
Norway has 2,805 housing units, 27% built before 1940 and 58% before 1980, with 22% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2301754000, checked 2026-10-19).
Norway has 4 points more pre-1940 homes than Oxford County as a whole (23%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US23017, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Norway home was built in 1974 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2301754000, checked 2026-10-19) and the median home has 5.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2301754000, checked 2026-10-19).
70% of Norway homes are single-family detached, 14% are in two- to four-unit buildings and 2% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2301754000, checked 2026-10-19).
With 70% detached houses and 14% in small multi-family buildings, a Norway quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 30% of Norway homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2301754000, checked 2026-10-19), the landlord signs the quote in many of them.
Norway has 5 points fewer detached houses than Oxford County overall (75%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US23017, checked 2026-10-19).
No electric utility is on file for Norway 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 Norway address before counting it. With 12% of Norway homes already on electric heat and 77% 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 Norway is $54,342 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2301754000, 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: -18F.

That -18F figure is the Oxford County cold-day number a Norway heat pump is sized against, so ask the installer to show the system's heating output at -18F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 67% of the 2,164 occupied Norway homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Norway home has 5.4 rooms and was built around 1974, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
