Portland / Ontario
Ontario has 11,842 residents (give or take 32) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4154900, checked 2026-10-19), about 1,979 people per square mile.
Ontario is about 297 miles from the Census center point for Portland in a straight line and covers 5.985 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).
Of the 4,575 occupied homes in Ontario, 42% heat with natural gas, 0% with heating oil, 55% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4154900, checked 2026-10-19).
Electricity already heats 55% of Ontario homes, ahead of gas at 42%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Ontario has 3 points less oil heat than Malheur County as a whole, where 3% of homes burn oil, and 2 points more electric heat than the county's 53% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US41045, checked 2026-10-19).
Ontario has 4,938 housing units, 7% built before 1940 and 54% before 1980, with 13% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4154900, checked 2026-10-19).
Ontario has 4 points fewer pre-1940 homes than Malheur County as a whole (11%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US41045, checked 2026-10-19).
The median Ontario home was built in 1978 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4154900, checked 2026-10-19) and the median home has 4.8 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4154900, checked 2026-10-19).
55% of Ontario homes are single-family detached, 20% are in two- to four-unit buildings and 13% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4154900, checked 2026-10-19).
44% of Ontario homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4154900, checked 2026-10-19), so beside the 55% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Ontario has 10 points fewer detached houses than Malheur County overall (65%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US41045, checked 2026-10-19).
44% of Ontario homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4154900, 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 Ontario 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 Ontario address before counting it. With 55% of Ontario homes already on electric heat and 42% 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 Ontario is $46,308 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4154900, 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: 8F.

That 8F figure is the Malheur County cold-day number a Ontario heat pump is sized against, so ask the installer to show the system's heating output at 8F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Ontario home has 4.8 rooms and was built around 1978, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
