Portland / York
York has 13,986 residents (give or take 22) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2303187985, checked 2026-10-19), about 256 people per square mile.
York is about 38 miles from the Census center point for Portland in a straight line and covers 54.699 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 York that is 03902, 03909, 03910, 03911 (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).
York is spread out at 256 people per square mile across 54.699 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 5,501 occupied homes in York, 4% heat with natural gas, 55% with heating oil, 10% with electricity and 22% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2303187985, checked 2026-10-19).
Heating oil is the largest single fuel in York at 55%, ahead of propane at 22%, 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.
York has 5 points less oil heat than York County as a whole, where 60% of homes burn oil, and the same 10% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US23031, checked 2026-10-19).
York has 8,795 housing units, 22% built before 1940 and 56% before 1980, with 20% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2303187985, checked 2026-10-19).
York has 4 points fewer homes built after 2000 than the county's 24% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US23031, checked 2026-10-19).
The median York home was built in 1977 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2303187985, checked 2026-10-19) and the median home has 6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=060XX00US2303187985, checked 2026-10-19).
83% of York homes are single-family detached, 9% are in two- to four-unit buildings and 4% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=060XX00US2303187985, checked 2026-10-19).
With 83% detached houses and 9% in small multi-family buildings, a York quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 19% of York homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2303187985, checked 2026-10-19), the landlord signs the quote in many of them.
York has 13 points more detached houses than York County overall (70%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US23031, checked 2026-10-19).
No electric utility is on file for York 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 York address before counting it. With 10% of York homes already on electric heat and 81% 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 York is $121,250 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2303187985, 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 0F figure is the York County cold-day number a York heat pump is sized against, so ask the installer to show the system's heating output at 0F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 55% of the 5,501 occupied York homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; the median York home has 6 rooms and was built around 1977, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
