The home energy rebate guide I wish every owner got
Heat pumps, insulation, new appliances, lower bills — even free upgrades if you qualify. In plain English, with a calculator that adds up what you can get back and tells you how to qualify.
I’m Genaro, a local real estate broker. Most Whatcom homeowners leave real money on the table here — sometimes thousands of it — simply because nobody put the programs in one place.

There’s no single place that lists what a Whatcom homeowner can actually get. So here it is — and an estimator that does the math for you. Check the upgrades you’re considering: it adds up your rebates from PSE, Cascade Natural Gas, and local programs, and shows you exactly how to qualify for each one.
What can you get back?
Set your situation, then tap an upgrade to see its rebate, what you need to qualify, and whether it needs a pro. The total updates as you go.
Your home
Income-qualified status increases most rebates and unlocks free programs (HEAR, weatherization) plus the monthly bill discount.
- Income under ~80% area median (≈$60,700 for 1, ≈$86,700 for 4) for the boosted rebates
- Under ~60% state median (≈$44k for 1, ≈$84k for 4) for the free programs
- SNAP, TANF, SSI, or LIHEAP usually qualifies you automatically
- The Opportunity Council verifies — call 360-255-2192; often self-attested to start

Heat-pump rebates end Dec 31, 2026, and after Apr 2, 2026 you must use a PSE-approved installer.
Confirm the model qualifies before you buy, and file within the deadline (Cascade: 90 days from install).
