QUICK ANSWER
Seattle City Light customers can stack utility rebates with federal HEEHRA rebates (up to $8,000 for heat pumps, $1,750 for heat pump water heaters for qualifying households) and the federal home improvement tax credit (30% back, no income cap) for combined savings of $3,000–$10,000+ on major upgrades. Heat pumps, heat pump water heaters, insulation, and smart thermostats all qualify, and these incentives do not reduce each other.

Frequently Asked Questions
How do I know if my product qualifies for Seattle City Light rebates?
Most Seattle City Light rebate programs require products to be ENERGY STAR certified. Many also require a specific efficiency tier (for example, SEER2 rating of 16 or higher for central AC). Check the Seattle City Light website for the current qualifying product list before making any purchase.
Can I stack Seattle City Light rebates with federal tax credits?
Yes. Utility rebates and federal tax credits are entirely separate programs. The federal home improvement tax credit is calculated on the full cost before any rebates you receive, so receiving a utility rebate does not reduce your federal credit. You keep both.
How long does it take to receive a Seattle City Light rebate?
Most utility rebates are processed within 6-12 weeks of application submission. HEEHRA rebates from the contractor are applied at point of sale with no wait. Federal tax credits are received when you file your return.
