Seattle / Pasco
Pasco has 79,575 residents (give or take 25) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5353545, checked 2026-10-19), about 2,042 people per square mile.
Pasco is about 179 miles from the Census center point for Seattle in a straight line and covers 38.963 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 24,748 occupied homes in Pasco, 34% heat with natural gas, 0% with heating oil, 63% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5353545, checked 2026-10-19).
Electricity already heats 63% of Pasco homes, ahead of gas at 34%, and a home on electric baseboard sees the biggest bill change from a heat pump because it replaces resistance heat one for one.
Pasco has about the Franklin County oil share of 0% and 4 points less electric heat than the county's 67% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US53021, checked 2026-10-19).
Pasco has 25,678 housing units, 3% built before 1940 and 34% before 1980, with 51% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5353545, checked 2026-10-19).
Pasco has 4 points more homes built after 2000 than the county's 47% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US53021, checked 2026-10-19).
The median Pasco home was built in 2001 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5353545, checked 2026-10-19) and the median home has 5.6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5353545, checked 2026-10-19).
74% of Pasco homes are single-family detached, 5% are in two- to four-unit buildings and 12% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5353545, checked 2026-10-19).
With 74% detached houses and 5% in small multi-family buildings, a Pasco quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 29% of Pasco homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5353545, checked 2026-10-19), the landlord signs the quote in many of them.
51% of Pasco housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5353545, 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.
No electric utility is on file for Pasco 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 Pasco address before counting it. With 63% of Pasco homes already on electric heat and 35% 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 Pasco 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 Pasco address before counting it.
Median household income in Pasco is $85,586 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5353545, 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: 11F.

That 11F figure is the Franklin County cold-day number a Pasco 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 Pasco home has 5.6 rooms and was built around 2001, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
