Portland / Farmington
Farmington has 8,157 residents (give or take 23) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2300724775, checked 2026-10-19), about 147 people per square mile.
Farmington is about 72 miles from the Census center point for Portland in a straight line and covers 55.676 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 Farmington that is 04938, 04940, 04992 (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).
Farmington is spread out at 147 people per square mile across 55.676 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 3,502 occupied homes in Farmington, 5% heat with natural gas, 44% with heating oil, 20% with electricity and 20% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2300724775, checked 2026-10-19).
Heating oil is the largest single fuel in Farmington at 44%, ahead of electricity at 20%, 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.
Farmington has 8 points less oil heat than Franklin County as a whole, where 52% of homes burn oil, and 9 points more electric heat than the county's 11% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US23007, checked 2026-10-19).
Farmington has 3,939 housing units, 23% built before 1940 and 60% before 1980, with 18% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2300724775, checked 2026-10-19).
Farmington has 4 points more pre-1940 homes than Franklin County as a whole (19%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US23007, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Farmington home was built in 1975 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2300724775, checked 2026-10-19) and the median home has 5.1 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2300724775, checked 2026-10-19).
53% of Farmington homes are single-family detached, 10% are in two- to four-unit buildings and 23% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2300724775, checked 2026-10-19).
45% of Farmington homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2300724775, checked 2026-10-19), so beside the 53% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Farmington has 22 points fewer detached houses than Franklin County overall (75%) and 15 points more five-plus-unit buildings than the county's 8% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US23007, checked 2026-10-19).
45% of Farmington homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2300724775, checked 2026-10-19), so the market splits between resident-led jobs where the occupant picks the system and landlord-led jobs where they do not, and the rebate paperwork differs.
60% of Farmington homes were built before 1980 and only 18% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2300724775, 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 Farmington 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 Farmington address before counting it. With 20% of Farmington homes already on electric heat and 69% 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 Farmington is $54,276 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2300724775, 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.

That -7F figure is the Franklin County cold-day number a Farmington heat pump is sized against, so ask the installer to show the system's heating output at -7F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 44% of the 3,502 occupied Farmington homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median Farmington home has 5.1 rooms and was built around 1975, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
