Seattle / Leavenworth
Leavenworth has 2,569 residents (give or take 16) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5338845, checked 2026-10-19), about 1,768 people per square mile.
Leavenworth is about 79 miles from the Census center point for Seattle in a straight line and covers 1.453 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 1,211 occupied homes in Leavenworth, 2% heat with natural gas, 0% with heating oil, 97% with electricity and 0% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5338845, checked 2026-10-19).
Electricity already heats 97% of Leavenworth homes, ahead of gas at 2%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Leavenworth has about the Chelan County oil share of 0% and 4 points more electric heat than the county's 93% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US53007, checked 2026-10-19).
Leavenworth has 1,507 housing units, 16% built before 1940 and 45% before 1980, with 29% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5338845, checked 2026-10-19).
Leavenworth has 3 points more pre-1940 homes than Chelan County as a whole (13%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US53007, checked 2026-10-19). An older stock means more insulation upgrades before the heat pump goes in.
The median Leavenworth home was built in 1984 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5338845, 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=160XX00US5338845, checked 2026-10-19).
53% of Leavenworth homes are single-family detached, 16% are in two- to four-unit buildings and 29% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5338845, checked 2026-10-19).
48% of Leavenworth homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5338845, 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.
Leavenworth has 15 points fewer detached houses than Chelan County overall (68%) and 17 points more five-plus-unit buildings than the county's 12% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US53007, checked 2026-10-19).
48% of Leavenworth homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5338845, 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 Leavenworth on this door yet, so this page does not name one; the name on the bill decides which rebate path applies.
PSE heat pump rebates (electric resistance to ASHP conversion), run by Puget Sound Energy, is a live program for Washington addresses and covers qualifying equipment at $2,400 per system (registry row 14 verified 2026-10-14, https://www.pse.com/en/rebates/heating/electric-resistance-to-air-source-heat-pump-conversion-rebate, checked 2026-10-16); confirm eligibility for the Leavenworth address before counting it. With 97% of Leavenworth homes already on electric heat and 2% on gas, oil or propane, the row that applies depends on the name on the electric bill and the fuel coming out.
Seattle City Light heat pump instant discounts, run by Seattle City Light, is a live program for Washington addresses and lists a standard figure of $300 (registry row 47 verified 2026-10-16, https://seattle.gov/city-light/residential-services/home-energy-solutions/heating-and-cooling-your-home, checked 2026-10-16); confirm eligibility for the Leavenworth address before counting it.
Seattle Clean Heat Program (oil to heat pump), run by City of Seattle Office of Sustainability and Environment, is a live program for Washington addresses and lists a standard figure of $2,000 (registry row 48 verified 2026-10-14, https://seattle.gov/environment/climate-change/buildings-and-energy/seattles-clean-heat-program, checked 2026-10-16); confirm eligibility for the Leavenworth address before counting it.
Median household income in Leavenworth is $69,943 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5338845, 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: 12F.

That 12F figure is the Chelan County cold-day number a Leavenworth heat pump is sized against, so ask the installer to show the system's heating output at 12F, not at the milder rating-label temperature.
Ask for the heat-loss calculation room by room; the median Leavenworth home has 4.8 rooms and was built around 1984, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
