Published June 29 2026 Recipients healthier and more comfortable as they support climate goals Energy Smart Eastside, a collaboration of six Eastside cities supporting equitable access to clean home energy solutions, has helped 1,000 households install heat pumps. Installed over the last four years, since ESE launched in 2022, those heat pumps have helped reduce emissions from residential energy use, one of the region’s largest sources of climate pollution, cutting more than 31,000 metric tons of carbon emissions so far. That’s roughly equivalent to taking 7,231 cars off the road for one year over the lifetime of the equipment.

Since heat pumps provide cooling as well as heating, she said she is looking forward to the cooler summers, a better night’s sleep and being able to chat with family during a movie without noise from fans. “It’s so exciting to be part of the program,” Treadway said. “It’s made a difference in our community and I’m hoping we can be a role model for other communities.” Advocating for her community After moving with her family from Nebraska to Washington, Treadway and her family faced the unprecedented summer temperatures of 2021. Motivated to find a long-term cooling solution, she began investigating heat pumps for her condominium community, Ashford at Vista Park, part of the A Regional Coalition for Housing (ARCH) affordable homeownership program. Treadway reached out to the City of Issaquah and was connected to the ESE program. She advocated, not only for herself, but also for her community by coordinating contractors and helping establish policies about heat pump installations on her homeowners’ board. ESE covered the full cost of heat pumps for five income-qualified households and provided substantial rebates for 17 additional moderate-income households. Combined with
