Portland / North Plains
North Plains has 3,433 residents (give or take 47) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4153150, checked 2026-10-19), about 3,150 people per square mile.
North Plains is about 17 miles from the Census center point for Portland in a straight line and covers 1.09 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).
3,150 people per square mile puts North Plains in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 1,287 occupied homes in North Plains, 63% heat with natural gas, 0% with heating oil, 35% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4153150, checked 2026-10-19).
Gas heats 63% of North Plains against electricity at 35%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
North Plains has about the Washington County oil share of 1% and 11 points less electric heat than the county's 46% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US41067, checked 2026-10-19).
North Plains has 1,287 housing units, 4% built before 1940 and 16% before 1980, with 50% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4153150, checked 2026-10-19).
North Plains has 19 points more homes built after 2000 than the county's 31% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US41067, checked 2026-10-19).
The median North Plains home was built in 2000 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4153150, checked 2026-10-19) and the median home has 5.4 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4153150, checked 2026-10-19).
91% of North Plains homes are single-family detached, 2% 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=160XX00US4153150, checked 2026-10-19).
With 91% detached houses and 2% in small multi-family buildings, a North Plains quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 17% of North Plains homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4153150, checked 2026-10-19), the landlord signs the quote in many of them.
North Plains has 34 points more detached houses than Washington County overall (57%) and 23 points fewer five-plus-unit buildings than the county's 25% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US41067, checked 2026-10-19).
50% of North Plains housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4153150, checked 2026-10-19), and homes that recent usually meet the insulation codes in place at the time, so a heat pump sized to the floor plan lands closer to the real load than it would in an older neighborhood.
No electric utility is on file for North Plains 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 North Plains address before counting it. With 35% of North Plains homes already on electric heat and 63% 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 North Plains is $117,639 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4153150, 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.

That 24F figure is the Washington County cold-day number a North Plains 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 whether the quote is whole-home or partial-home, because with 63% of North Plains on gas and 35% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median North Plains home has 5.4 rooms and was built around 2000, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
