Federal stack (25C, 25D, HOMES, HEAR) plus utility rebates form the rebate foundation. Climate-specific priorities depend on whether your home's primary load is heating, cooling, or balanced.
How to put together your Washington rebate stack
- Identify your utility from the list above and visit their efficiency-program page for current rebate offerings.
- Check Washington State Department of Commerce — Energy's site for HOMES and HEAR rollout status (whether the program is live in your county and what contractors are approved).
- Confirm equipment eligibility — federal 25C requires CEE Tier 2 or ENERGY STAR Most Efficient depending on category; utility programs often require ENERGY STAR.
- Get pre-approval if your utility or HOMES requires it (many do — skipping pre-approval voids the rebate).
- Install via a licensed contractor; collect AHRI certificate, manufacturer's certification statement, and itemized invoice.
- Submit utility rebate within the post-install window (typically 30-90 days). File federal credits via IRS Form 5695 with your tax return for the year equipment was placed in service.
