Quick answer
Puget Sound homeowners upgrading to efficient heat pumps, ductless systems, or hybrid water heaters may qualify for utility rebates (PSE, Seattle City Light, SnoPUD, Tacoma Power) and Washington's income-qualified HEAR point-of-sale discounts — eligibility depends on the equipment tier, household income, your installer's network status, and program timing. (The federal 25C tax credit expired December 31, 2025, so 2026 savings come from state and utility programs.)
- Two layers can stack in 2026: utility rebates and Washington's income-qualified HEAR program — the federal 25C credit ended after 2025.
- PSE pays its heat pump rebates only when a PSE Trade Ally or Recommended Energy Professional installs the system — Eco is a Trade Ally Network member.
- Each layer has its own efficiency minimums and paperwork rules.
- Equipment must meet the program's tier — buy with rebates in mind, not after.
- Net cost after incentives is the number that matters, not sticker price.
Before you sign an install contract
Rebates and credits can change a project's total cost by thousands of dollars, and many require that you choose qualifying equipment and follow specific steps before installation. Understanding the stackable incentives up front — rather than discovering them afterward — prevents leaving money on the table and steers your equipment choice toward the tier that captures the most savings.
When you're comparing quotes
A lower sticker price isn't the better deal if it uses equipment that doesn't qualify for incentives. The honest comparison between bids is net cost after rebates and credits, plus efficiency and warranty. This is exactly where a rebate-aware estimate helps you compare apples to apples instead of being misled by the headline number.
How it works
Common program layers
Utility rebates (equipment-specific, often processed by your contractor on your behalf) reward installing efficient heat pumps and ductless systems — and PSE's heat pump rebates carry an installer rule: the work must be performed by a PSE Trade Ally or Recommended Energy Professional (REP), or the rebate is disqualified. Income-qualified programs — Washington's HEAR point-of-sale discounts for households at or below 150% of area median income — can add substantial savings for eligible households. The federal 25C tax credit expired December 31, 2025 and no longer applies to new installs. Each remaining layer sets its own efficiency minimums and documentation requirements.
Why equipment tier matters
Programs don't reward just any new system — they target specific efficiency ratings (HSPF2/SEER2) and, sometimes, cold-climate certification. Choosing a unit one tier below the threshold can forfeit a large rebate. That's why the smart sequence is to identify the incentives first, then select equipment that meets the qualifying tier while still fitting your home's load and your budget.
How Eco helps
We identify the rebates and credits you may qualify for during the estimate, recommend equipment that meets the qualifying tiers, and handle the rebate paperwork as part of eligible installs so you're not navigating utility forms alone. As a PSE Trade Ally Network member, Eco is set up to submit PSE instant rebates for you. Program details shift over time, so we confirm current availability and amounts at the time of your project rather than relying on last year's numbers.
Key terms and context
This guide is written for heating & air decisions in the Puget Sound. It uses the same terminology you'll hear from inspectors, technicians, and permit offices.
Rebate mistakes
The classic errors: installing non-qualifying equipment, missing a pre-approval or pre-installation step, or attempting a DIY install that can't be rebated at all. Generic online prices almost never reflect the rebate-adjusted net cost, which makes them poor benchmarks. Each of these mistakes can cost more than the rebate itself.
Treating incentives as guaranteed
Programs change funding levels, eligibility, and deadlines, and some have limited budgets that run out. Treating a rebate as locked-in before it's confirmed can blow up a budget. The safe approach is verifying current program rules and securing required approvals before committing to equipment.
How we build this guidance
- Program details checked against published utility and IRS guidance.
- Incentives change frequently — Eco confirms current rules and amounts at estimate time.
- We recommend qualifying equipment tiers and handle eligible rebate paperwork for you.
Methodology: Program details verified against published utility program pages (pse.com, seattle.gov, snopud.com, commerce.wa.gov) and IRS guidance, July 2026; programs change frequently — confirm current eligibility and amounts at the time of your estimate.

Common questions
Can rebates stack?
Often, yes. Utility rebates and income-qualified programs like WA HEAR can frequently combine if each program's rules allow it, which can substantially lower net cost. The combination depends on your equipment, household income, and current program terms. Eco maps what's available and stackable for your specific project at estimate time.
Do I have to do anything before installation to qualify?
Sometimes. Certain programs require pre-approval, specific equipment models, or documentation gathered before or during the install. Missing those steps can disqualify an otherwise eligible project. This is a key reason to plan incentives before signing, and why Eco walks through the requirements as part of a rebate-aware estimate.
Is the federal 25C tax credit still available for heat pumps?
No. The federal 25C energy-efficiency tax credit — the one worth up to $2,000 on qualifying heat pumps — expired December 31, 2025. If your system was placed in service by that date you can still claim it on your 2025 return, but for 2026 installations there is no federal residential heat pump tax credit. Today's savings come from utility rebates and Washington's income-qualified HEAR program instead.
Will my income affect which programs I can use?
It can. Utility rebates are generally available regardless of income (subject to equipment rules — and income-qualified tiers like PSE's Efficiency Boost pay more), while HEAR-style programs are income-qualified (≤150% of area median income) and can offer larger savings for eligible households. Eco helps determine which layers apply to your situation during the estimate.
Why can't I just look up a guaranteed rebate amount online?
Because amounts, eligibility, and funding change over time and depend on your exact equipment and circumstances. Published figures are useful for ballpark planning but shouldn't be treated as locked-in. Eco verifies current program rules and amounts when you're ready to move forward, so your net-cost numbers are real.
