Portland / Portland
Portland is the city this door is named for; it covers 133.492 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).
Portland has 641,165 residents (give or take 734) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4159000, checked 2026-10-19), about 4,803 people per square mile.
The quote form takes a ZIP code; for Portland that is 97201, 97202, 97203, 97204, 97205, 97206, 97208, 97209 and 21 more (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).
4,803 people per square mile puts Portland in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 289,705 occupied homes in Portland, 47% heat with natural gas, 2% with heating oil, 49% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4159000, checked 2026-10-19).
Portland has about the Multnomah County oil share of 2% and the same 49% electric share (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US41051, checked 2026-10-19).
Electricity already heats 49% of Portland homes, ahead of gas at 47%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
The median Portland home was built in 1966 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4159000, checked 2026-10-19) and the median home has 4.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4159000, checked 2026-10-19).
Portland has 307,719 housing units, 27% built before 1940 and 63% before 1980, with 24% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4159000, checked 2026-10-19).
Portland has 4 points more pre-1940 homes than Multnomah County as a whole (23%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US41051, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
63% of Portland homes were built before 1980 and only 24% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4159000, 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.
52% of Portland homes are single-family detached, 8% are in two- to four-unit buildings and 33% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4159000, checked 2026-10-19).
48% of Portland homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4159000, checked 2026-10-19), so beside the 52% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
48% of Portland homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4159000, 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.
No electric utility is on file for Portland on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
Energy Trust of Oregon heat pump incentives, run by Energy Trust of Oregon, is a live program for Oregon addresses and covers qualifying equipment at $1,000 per system (registry row 15 verified 2026-10-15, https://www.energytrust.org/incentives/residential-cooling-solutions/, checked 2026-10-16); confirm eligibility for the Portland address before counting it. With 49% of Portland homes already on electric heat and 50% 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 Portland is $90,919 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4159000, 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: 24F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Multnomah County row, 99% heating, PDF pages 100 to 102 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 24F figure is the Multnomah County cold-day number a Portland heat pump is sized against, so ask the installer to show the system's heating output at 24F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Portland home has 4.7 rooms and was built around 1966, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
