Spokane Valley has 106,365 residents (give or take 56) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5367167, checked 2026-10-19), about 2,820 people per square mile.
Spokane Valley is about 238 miles from the Census center point for Seattle in a straight line and covers 37.72 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 Spokane Valley that is 99037, 99206, 99212, 99216 (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).
Of the 42,775 occupied homes in Spokane Valley, 49% heat with natural gas, 1% with heating oil, 47% with electricity and 1% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5367167, checked 2026-10-19).
Gas heats 49% of Spokane Valley against electricity at 47%, so most quotes here are a partial-home system that carries the shoulder seasons and the summer while the gas furnace handles the coldest nights, or a whole-home system when the house is ready for it.
Spokane Valley has about the Spokane County oil share of 1% and 2 points more electric heat than the county's 45% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US53063, checked 2026-10-19).
Spokane Valley has 45,467 housing units, 5% built before 1940 and 52% before 1980, with 25% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5367167, checked 2026-10-19).
Spokane Valley has 9 points fewer pre-1940 homes than Spokane County as a whole (14%) (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US53063, checked 2026-10-19).
The median Spokane Valley home was built in 1979 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5367167, 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=160XX00US5367167, checked 2026-10-19).
60% of Spokane Valley homes are single-family detached, 5% are in two- to four-unit buildings and 25% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5367167, checked 2026-10-19).
42% of Spokane Valley homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5367167, checked 2026-10-19), so beside the 60% detached houses there is a real share of jobs where the landlord, not the resident, signs the quote.
Spokane Valley has 5 points fewer detached houses than Spokane County overall (65%) (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US53063, checked 2026-10-19).
42% of Spokane Valley homes are rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5367167, 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 Spokane Valley 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 Spokane Valley address before counting it. With 47% of Spokane Valley homes already on electric heat and 51% 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 Spokane Valley 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 Spokane Valley address before counting it.
Median household income in Spokane Valley is $74,042 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5367167, 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: 8F. Source: ENERGY STAR Design Temperature Limit Reference Guide (2019 Edition), Spokane County row, 99% heating, PDF pages 133 to 135 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 8F figure is the Spokane County cold-day number a Spokane Valley heat pump is sized against, so ask the installer to show the system's heating output at 8F, not at the milder rating-label temperature.
Ask whether the quote is whole-home or partial-home, because with 49% of Spokane Valley on gas and 47% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Spokane Valley home has 5.6 rooms and was built around 1979, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
