Portland / Corvallis
Corvallis has 59,960 residents (give or take 78) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4115800, checked 2026-10-19), about 4,127 people per square mile.
Corvallis is about 74 miles from the Census center point for Portland in a straight line and covers 14.529 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 Corvallis that is 97331 (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).
Median household income in Corvallis is $65,012 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4115800, 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.
4,127 people per square mile puts Corvallis in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
47% of Corvallis homes are single-family detached, 12% 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=160XX00US4115800, checked 2026-10-19).
58% of Corvallis homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4115800, checked 2026-10-19), so beside the 47% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Corvallis has 12 points fewer detached houses than Benton County overall (59%) and 11 points more five-plus-unit buildings than the county's 22% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US41003, checked 2026-10-19).
58% of Corvallis homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4115800, 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.
Of the 23,980 occupied homes in Corvallis, 36% heat with natural gas, 0% with heating oil, 60% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4115800, checked 2026-10-19).
Electricity already heats 60% of Corvallis homes, ahead of gas at 36%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Corvallis has about the Benton County oil share of 0% and 5 points more electric heat than the county's 55% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US41003, checked 2026-10-19).
No electric utility is on file for Corvallis 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 Corvallis address before counting it. With 60% of Corvallis homes already on electric heat and 37% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Corvallis has 25,628 housing units, 8% built before 1940 and 54% before 1980, with 23% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4115800, checked 2026-10-19).
Corvallis tracks Benton County on housing age, with the county at 8% pre-1940 and 25% post-2000 (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US41003, checked 2026-10-19).
The median Corvallis home was built in 1978 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4115800, checked 2026-10-19) and the median home has 4.9 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4115800, checked 2026-10-19).

That 22F figure is the Benton County cold-day number a Corvallis heat pump is sized against, so ask the installer to show the system's heating output at 22F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Corvallis home has 4.9 rooms and was built around 1978, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
