Portland / Lisbon Falls
Lisbon Falls has 4,267 residents (give or take 474) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US2340105, checked 2026-10-19), about 1,160 people per square mile.
Lisbon Falls is about 27 miles from the Census center point for Portland in a straight line and covers 3.679 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 Lisbon Falls that is 04252 (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).
Of the 1,714 occupied homes in Lisbon Falls, 3% heat with natural gas, 64% with heating oil, 8% with electricity and 15% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US2340105, checked 2026-10-19).
Heating oil is the largest single fuel in Lisbon Falls at 64%, ahead of propane at 15%, 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.
Lisbon Falls has 5 points more oil heat than Androscoggin County as a whole, where 59% of homes burn oil, and 1 points less electric heat than the county's 9% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US23001, checked 2026-10-19).
Lisbon Falls has 1,714 housing units, 27% built before 1940 and 68% before 1980, with 7% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2340105, checked 2026-10-19).
Lisbon Falls has 10 points fewer homes built after 2000 than the county's 17% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US23001, checked 2026-10-19).
The median Lisbon Falls home was built in 1967 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US2340105, 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=160XX00US2340105, checked 2026-10-19).
69% of Lisbon Falls homes are single-family detached, 21% 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=160XX00US2340105, checked 2026-10-19).
30% of Lisbon Falls homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US2340105, checked 2026-10-19), so beside the 69% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Lisbon Falls has 11 points more detached houses than Androscoggin County overall (58%) and 13 points fewer five-plus-unit buildings than the county's 15% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US23001, checked 2026-10-19).
68% of Lisbon Falls homes were built before 1980 and only 7% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US2340105, checked 2026-10-19), so most of the stock predates modern insulation codes; the installer's heat-loss calculation, not a square-footage rule, decides the tonnage.
No electric utility is on file for Lisbon Falls 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 Lisbon Falls address before counting it. With 8% of Lisbon Falls homes already on electric heat and 82% 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 Lisbon Falls is $72,344 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US2340105, 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.

That -4F figure is the Androscoggin County cold-day number a Lisbon Falls 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 64% of the 1,714 occupied Lisbon Falls homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Lisbon Falls home has 5.4 rooms and was built around 1967, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
