Heat Pump Rebates in King County and Pierce County, WA
If you live in King County or Pierce County, you may qualify for heat pump rebates that can help lower the cost of upgrading your home heating and cooling system. Rebate amounts depend on your utility provider, city, current heating system, income level, and the type of heat pump installed.
This guide covers some of the main heat pump rebate programs available in areas such as Covington, Seattle, Bellevue, Issaquah, Kirkland, Mercer Island, Redmond, Sammamish, Tacoma, and surrounding communities.
Puget Sound Energy Heat Pump Rebates
For many King County cities, including Covington, Puget Sound Energy, also known as PSE, is often the main rebate source for heat pump upgrades.
PSE heat pump rebates may include:
- Electric resistance heat to heat pump rebates
- Hybrid heat pump rebates
- Heat pump to heat pump upgrade rebates
- Income-qualified gas to electric heat pump rebates
PSE currently lists a $1,500 rebate for replacing electric resistance heating with a qualifying air-source heat pump. Income-qualified customers may also qualify for a $2,400 Efficiency Boost rebate. For eligible households switching from natural gas heat to an electric heat pump, PSE may offer rebates up to $4,000.
To qualify, installations must meet PSE program requirements and typically must be completed by a PSE Recommended Energy Professional or Trade Ally.
Seattle Clean Heat Program
Seattle homeowners with oil heat may qualify for rebates through the Seattle Clean Heat Program. This program helps homeowners switch from oil heat to an energy-efficient electric heat pump.
The City of Seattle currently offers a $2,000 instant rebate for eligible oil-to-heat-pump conversions using a qualified Mitsubishi electric heat pump. Moderate-income households may qualify for an additional $4,000 bonus, which can bring the total rebate up to $6,000.
Bonus rebates are listed for installations completed by September 30, 2026. Income-qualified households may also be eligible for a free heat pump conversion.
This program is especially helpful for Seattle homeowners who still use oil heat and want to upgrade to a cleaner, more efficient heating and cooling system.
Energy Smart Eastside Heat Pump Rebates
Energy Smart Eastside serves several Eastside communities, including Bellevue, Issaquah, Kirkland, Mercer Island, Redmond, and Sammamish.
The program currently lists a $6,000 Fuel Switch Rebate for eligible households switching from natural gas, propane, oil, or wood heat to a qualifying Mitsubishi, Bryant, or Carrier heat pump. This rebate is income-based and is generally available to households under 150% of area median income.
Energy Smart Eastside also lists a $1,000 rebate for eligible Eastside residents installing a Mitsubishi, Carrier, or Bryant heat pump when they are not using the Fuel Switch Rebate.
For households under 80% of area median income, the Energy Smart Eastside Boost Program may fully cover the cost of a heat pump installation.
King County Energize Program
King County’s Energize program provides heat pump and weatherization support in select areas of King, Kitsap, Pierce, and Snohomish Counties.
Energize Duvall is currently accepting applications for Duvall-area residents with natural gas heating. Eligible homeowners may qualify for a free heat pump and other energy upgrades.
King County also offers multifamily and community-space programs. Depending on the project and eligibility, some upgrades may receive up to 100% cost coverage.
