Portland / Gladstone
Gladstone has 11,977 residents (give or take 29) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US4129000, checked 2026-10-19), about 4,995 people per square mile.
Gladstone is about 11 miles from the Census center point for Portland in a straight line and covers 2.398 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 Gladstone that is 97027 (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).
4,995 people per square mile puts Gladstone in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
Of the 5,097 occupied homes in Gladstone, 52% heat with natural gas, 1% with heating oil, 45% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US4129000, checked 2026-10-19).
Gas heats 52% of Gladstone against electricity at 45%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Gladstone has about the Clackamas County oil share of 1% and 1 points less electric heat than the county's 46% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US41005, checked 2026-10-19).
Gladstone has 5,136 housing units, 11% built before 1940 and 63% before 1980, with 14% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4129000, checked 2026-10-19).
Gladstone has 4 points more pre-1940 homes than Clackamas County as a whole (7%) and 12 points fewer homes built after 2000 than the county's 26% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US41005, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Gladstone home was built in 1976 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US4129000, checked 2026-10-19) and the median home has 5.7 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US4129000, checked 2026-10-19).
63% of Gladstone homes are single-family detached, 9% are in two- to four-unit buildings and 17% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US4129000, checked 2026-10-19).
35% of Gladstone homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US4129000, checked 2026-10-19), so beside the 63% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
63% of Gladstone homes were built before 1980 and only 14% in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US4129000, 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.
No electric utility is on file for Gladstone 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 Gladstone address before counting it. With 45% of Gladstone homes already on electric heat and 53% 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 Gladstone is $91,250 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US4129000, 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), Clackamas 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 Clackamas County cold-day number a Gladstone 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 52% of Gladstone on gas and 45% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Gladstone home has 5.7 rooms and was built around 1976, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
