Seattle / Redmond
Redmond has 77,353 residents (give or take 55) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5357535, checked 2026-10-19), about 4,668 people per square mile.
Redmond is about 12 miles from the Census center point for Seattle in a straight line and covers 16.57 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 Redmond that is 98052 (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 Redmond is $162,560 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5357535, 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.
4,668 people per square mile puts Redmond in suburban density, where the outdoor unit usually sits in a side yard and the noise is not an issue for neighbors.
36% of Redmond homes are single-family detached, 8% are in two- to four-unit buildings and 47% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5357535, checked 2026-10-19).
With 47% of Redmond homes in buildings of five or more units and 36% detached, the condo association usually decides where outdoor units can go, so that approval comes before the quote. With 57% of Redmond homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5357535, checked 2026-10-19), the landlord signs the quote in many of them.
Redmond has 14 points fewer detached houses than King County overall (50%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US53033, checked 2026-10-19).
57% of Redmond homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5357535, 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 33,100 occupied homes in Redmond, 38% heat with natural gas, 0% with heating oil, 59% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5357535, checked 2026-10-19).
Electricity already heats 59% of Redmond homes, ahead of gas at 38%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Redmond has about the King County oil share of 2% and 4 points more electric heat than the county's 55% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US53033, checked 2026-10-19).
No electric utility is on file for Redmond on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.

With 59% of Redmond homes already on electric heat and 39% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.

Redmond has 35,104 housing units, 2% built before 1940 and 26% before 1980, with 40% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5357535, checked 2026-10-19).
Redmond has 9 points fewer pre-1940 homes than King County as a whole (11%) and 10 points more homes built after 2000 than the county's 30% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US53033, checked 2026-10-19).
The median Redmond home was built in 1993 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5357535, checked 2026-10-19) and the median home has 4.2 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5357535, checked 2026-10-19).
40% of Redmond housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5357535, 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.
Heating design temperature: 11F.

That 11F figure is the King County cold-day number a Redmond heat pump is sized against, so ask the installer to show the system's heating output at 11F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Redmond home has 4.2 rooms and was built around 1993, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
