Gresham has 112,378 residents (give or take 73) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4131250, checked 2026-10-19), about 4,769 people per square mile.
The quote form takes a ZIP code; for Gresham that is 97030, 97080, 97230, 97233 (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).
4,769 people per square mile puts Gresham in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 41,801 occupied homes in Gresham, 43% heat with natural gas, 0% with heating oil, 55% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4131250, checked 2026-10-19).
Gresham has about the Multnomah County oil share of 2% and 6 points more electric heat than the county's 49% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US41051, checked 2026-10-19).
Electricity already heats 55% of Gresham homes, ahead of gas at 43%, 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 Gresham home was built in 1981 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4131250, checked 2026-10-19) and the median home has 5.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4131250, checked 2026-10-19).
Gresham has 44,005 housing units, 3% built before 1940 and 48% before 1980, with 21% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4131250, checked 2026-10-19).
Gresham has 20 points fewer 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).
53% of Gresham homes are single-family detached, 10% are in two- to four-unit buildings and 28% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4131250, checked 2026-10-19).
44% of Gresham homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4131250, checked 2026-10-19), so beside the 53% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
44% of Gresham homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4131250, 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 Gresham 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 Gresham address before counting it. With 55% of Gresham homes already on electric heat and 44% 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 Gresham is $77,795 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4131250, 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 Multnomah County cold-day number a Gresham 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 Gresham home has 5.2 rooms and was built around 1981, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
