The federal energy tax credits have expired

Costs and payback figures on this page may still assume a federal credit that no longer exists. The 30% Residential Clean Energy Credit (25D) and the Energy Efficient Home Improvement Credit (25C) both ended for property placed in service after 31 December 2025, and the home EV charger credit (30C) ended after 30 June 2026. Assume no federal credit on work done today.

Is Electrification Worth It in Washington?

Cheapest electricity in the continental U.S. Thank you, hydropower.

Seattle averages $0.10/kWh. Spokane is even cheaper. Natural gas costs $1.40-1.80/therm, which isn't outrageous, but your climate is so mild (Portland-ish) that heat pumps barely have to work. And Washington has solid rebates through utility programs and state tax incentives.

Heat pumps are a great fit here. Low electricity costs + mild winters + decent incentives = 5-8 year payback. The one catch: Seattle's marine climate means moisture management matters. Make sure your HVAC contractor knows how to handle condensation and drainage properly—botched installs are the main complaint I see from Washington homeowners.

Which Upgrades Pay Off the Fastest?

The economics are broken down for each major upgrade. Pay attention to the payback period—that's how long until savings equal your net cost.
