About King County Energize for single family homes
King County’s Energize program installs heat pumps and other home efficiency upgrades in low and moderate income homes in King County. Eligibility is based on income and geographic boundaries as set by funding partners.
The Energize program aligns with King County’s commitments in the Strategic Climate Action Plan (SCAP):
- Energize prepares for the impacts of climate change by ensuring more people have access to cooling on hot days and heating on cold ones.
- Energize advances energy justice and reduces energy burdens in frontline communities – those communities that will experience the earliest and most severe climate impacts.
- Energize reduces greenhouse gas emissions by replacing inefficient gas and oil heating systems with cleaner electric heating and cooling.
Testimonials
Energize has served over 250 households since 2024 and is grateful to clients that have enrolled in the program! Hear from some of them about the impact it has made:
"We cannot be happier with the King County Energize program. The cost savings for those of us who are elderly and with low incomes is truly a blessing. Thank you so much."

Heat pumps are highly efficient heating and cooling systems that move hot air from one place to another. They've been around for 50+ years and are now the preferred heating and cooling system in Asia and much of Europe.
If you have a refrigerator, you already have heat pump technology in your home.
Ductless heating systems can save 25-50% in heating costs over traditional electric systems. They can save even more compared to oil heating systems.
