Seattle / Ridgefield
Ridgefield has 13,408 residents (give or take 26) (ACS 2020-2024 5-year, table B01003, https://data.census.gov/table/ACSDT5Y2024.B01003?g=160XX00US5358410, checked 2026-10-19), about 1,776 people per square mile.
Ridgefield is about 125 miles from the Census center point for Seattle in a straight line and covers 7.549 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 4,702 occupied homes in Ridgefield, 55% heat with natural gas, 0% with heating oil, 43% with electricity and 2% with propane (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=160XX00US5358410, checked 2026-10-19).
Gas heats 55% of Ridgefield against electricity at 43%, and a cold-climate heat pump sized for this market replaces the gas system outright, so the usual quote is a whole-home install.
Ridgefield has about the Clark County oil share of 0% and 19 points less electric heat than the county's 62% (ACS 2020-2024 5-year, table B25040, https://data.census.gov/table/ACSDT5Y2024.B25040?g=050XX00US53011, checked 2026-10-19).
Ridgefield has 4,722 housing units, 2% built before 1940 and 8% before 1980, with 80% built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5358410, checked 2026-10-19).
Ridgefield has 45 points more homes built after 2000 than the county's 35% (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=050XX00US53011, checked 2026-10-19).
The median Ridgefield home was built in 2012 (ACS 2020-2024 5-year, table B25035, https://data.census.gov/table/ACSDT5Y2024.B25035?g=160XX00US5358410, checked 2026-10-19) and the median home has 6 rooms (ACS 2020-2024 5-year, table B25018, https://data.census.gov/table/ACSDT5Y2024.B25018?g=160XX00US5358410, checked 2026-10-19).
80% of Ridgefield homes are single-family detached, 3% are in two- to four-unit buildings and 6% are in buildings of five or more units (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=160XX00US5358410, checked 2026-10-19).
With 80% detached houses and 3% in small multi-family buildings, a Ridgefield quote is usually one or two outdoor units with ducted or ductless heads sized room by room. With 18% of Ridgefield homes rented (ACS 2020-2024 5-year, table B25003, https://data.census.gov/table/ACSDT5Y2024.B25003?g=160XX00US5358410, checked 2026-10-19), the landlord signs the quote in many of them.
Ridgefield has 13 points more detached houses than Clark County overall (67%) and 12 points fewer five-plus-unit buildings than the county's 18% (ACS 2020-2024 5-year, table B25024, https://data.census.gov/table/ACSDT5Y2024.B25024?g=050XX00US53011, checked 2026-10-19).
80% of Ridgefield housing was built in 2000 or later (ACS 2020-2024 5-year, table B25034, https://data.census.gov/table/ACSDT5Y2024.B25034?g=160XX00US5358410, 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 Ridgefield 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 Ridgefield address before counting it. With 43% of Ridgefield homes already on electric heat and 57% 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 Ridgefield 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 Ridgefield address before counting it.
Median household income in Ridgefield is $116,389 (ACS 2020-2024 5-year, table B19013, https://data.census.gov/table/ACSDT5Y2024.B19013?g=160XX00US5358410, 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), Clark 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 24F figure is the Clark County cold-day number a Ridgefield 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 55% of Ridgefield on gas and 43% already electric the two paths carry different rebate figures and different sizing.
Ask for the heat-loss calculation room by room; the median Ridgefield home has 6 rooms and was built around 2012, and the count of heads and the tonnage follow the rooms and the insulation, not the square footage.
