Portland / Richmond
Richmond has 3,566 residents (give or take 15) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=060XX00US2302362645, checked 2026-10-19), about 117 people per square mile.
Richmond is about 38 miles from the Census center point for Portland in a straight line and covers 30.429 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 Richmond that is 04357 (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).
Richmond is spread out at 117 people per square mile across 30.429 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 1,599 occupied homes in Richmond, 1% heat with natural gas, 69% with heating oil, 6% with electricity and 17% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=060XX00US2302362645, checked 2026-10-19).
Heating oil is the largest single fuel in Richmond at 69%, ahead of propane at 17%, 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.
Richmond has 16 points more oil heat than Sagadahoc County as a whole, where 53% of homes burn oil, and 5 points less electric heat than the county's 11% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US23023, checked 2026-10-19).
Richmond has 1,782 housing units, 32% built before 1940 and 55% before 1980, with 23% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2302362645, checked 2026-10-19).
Richmond has 5 points more pre-1940 homes than Sagadahoc County as a whole (27%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US23023, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Richmond home was built in 1975 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=060XX00US2302362645, 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=060XX00US2302362645, checked 2026-10-19).
75% of Richmond homes are single-family detached, 11% 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=060XX00US2302362645, checked 2026-10-19).
With 75% detached houses and 11% in small multi-family buildings, a Richmond quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 30% of Richmond homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=060XX00US2302362645, checked 2026-10-19), the landlord signs the quote in many of them.
32% of Richmond homes were built before 1940 and 55% before 1980 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=060XX00US2302362645, 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 Richmond 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 Richmond address before counting it. With 6% of Richmond homes already on electric heat and 87% 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 Richmond is $65,854 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=060XX00US2302362645, 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: -2F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Sagadahoc County row, 99% heating, PDF pages 54 to 55 of 141 (Revised 11/11/2020), https://www.energystar.gov/sites/default/files/Design%20Temperature%20Limit%20Reference%20Guide%20(2019%20Ed)%20-%20ENERGY%20STAR%20Single-Family%20New%20Homes_Rev11.pdf, fetched 2026-10-19, 99%.
That -2F figure is the Sagadahoc County cold-day number a Richmond heat pump is sized against, so ask the installer to show the system's heating output at -2F, not at the milder rating-label temperature.
Ask what happens to the oil tank, since 69% of the 1,599 occupied Richmond homes have one and removal is usually a separate line on the quote.
Ask for the heat-loss calculation room by room; a Richmond house from before 1940 (32% of the 1,782 units) rarely matches a square-footage rule of thumb.
