Portland / Paris
Paris has 5,317 residents (give or take 14) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2301756625, checked 2026-10-19), about 130 people per square mile.
Paris is about 45 miles from the Census center point for Portland in a straight line and covers 40.774 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 Paris that is 04271, 04281 (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).
Paris is spread out at 130 people per square mile across 40.774 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 2,200 occupied homes in Paris, 5% heat with natural gas, 55% with heating oil, 20% with electricity and 8% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2301756625, checked 2026-10-19).
Heating oil is the largest single fuel in Paris at 55%, 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.
Paris has 3 points less oil heat than Oxford County as a whole, where 58% of homes burn oil, and 12 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).
Paris has 2,746 housing units, 32% built before 1940 and 48% before 1980, with 12% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2301756625, checked 2026-10-19).
Paris has 9 points more pre-1940 homes than Oxford County as a whole (23%) and 9 points fewer homes built after 2000 than the county's 21% (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 Paris home was built in 1981 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2301756625, checked 2026-10-19) and the median home has 5.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2301756625, checked 2026-10-19).
59% of Paris homes are single-family detached, 15% 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=060XX00US2301756625, checked 2026-10-19).
40% of Paris homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2301756625, checked 2026-10-19), so beside the 59% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Paris has 16 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).
40% of Paris homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2301756625, 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.
32% of Paris homes were built before 1940 and 48% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2301756625, checked 2026-10-19), so insulation is the first sizing question: an older home leaks more heat per square foot, and the installer runs a room-by-room heat-loss calculation to size the system for what the walls and windows actually hold in, not just the floor plan.
No electric utility is on file for Paris 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 Paris address before counting it. With 20% of Paris homes already on electric heat and 68% 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 Paris is $75,137 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2301756625, 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 Paris 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 55% of the 2,200 occupied Paris homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; a Paris house from before 1940 (32% of the 2,746 units) rarely matches a square-footage rule of thumb.
