Whatcom County Home Energy Rebate Guide (2026)

Whatcom County, Washington · 2026 guide

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.

How to qualify No install
  • 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

  • Tap the upgrades you’re considering to see your estimated rebates.
Because you’re income-qualified, you may also get a heat pump, water heater, induction stove, and panel upgrade for free through HEAR and free weatherization, plus 5–45% off your monthly bill. Those cover full costs rather than pay a fixed rebate, so they’re not added to the total above — call the Opportunity Council to apply.
Estimates use typical 2026 rebate amounts and program caps. Actual amounts depend on the equipment model, your contractor, and program funding. Confirm before you buy. PSE serves electricity countywide; gas is Cascade.

02 — The big rebates

Heat pumps, insulation & water heaters

This is where the real money is — and both your utilities pay for the same work. Check these in the estimator above to see your numbers and how to qualify.

  • PSE

    Heat pump — $1,500 ($2,400 income-qualified)

    Heat pump water heater $1,000; gas tankless $1,000 from Cascade.

  • Cascade

    Insulation — $2.50/sq ft attic, $5/sq ft wall

    Do two insulation jobs + air sealing for a $2,000 bundle bonus on top.

Time-sensitive: PSE heat-pump rebates end Dec 31, 2026, and after Apr 2, 2026 you must use a PSE-approved installer.

03 — Free if you qualify

Whole upgrades, covered start to finish

Switch on income-qualified in the estimator to flag these. Under ~60% of state median income (about $44k for one person, $84k for a family of four), these programs pay for the work — not just discount it.

    Free heat pumps & appliances

    Heat pump, water heater, induction stove, dryer, plus panel and wiring upgrades.

Three things that trip people up

Federal credits ended.

The 30% federal tax credits for insulation, heat pumps, windows, and solar ended Dec 31, 2025. Don’t count on them for 2026.

PSE deadlines are real.

Heat-pump rebates end Dec 31, 2026, and after Apr 2, 2026 you must use a PSE-approved installer.

File on time, buy the right model.

Confirm the model qualifies before you buy, and file within the deadline (Cascade: 90 days from install).

Questions

Common questions

Do I have to be low-income to get anything?
No. The big PSE and Cascade rebates (heat pumps, insulation, water heaters, thermostats) are open to all customers. Income-qualified status just boosts those amounts and unlocks the free programs — so switch it on in the estimator only if it applies.
Which upgrades can I install myself?
A few — a smart thermostat and an exterior door can be self-installed and still earn the rebate (keep your receipt). The bigger items (heat pump, water heater, insulation, windows, EV charger) must be done by an approved or licensed contractor. Each tile in the estimator shows a “Pro install” or “DIY OK” flag.
Can I stack rebates from more than one program?
Often yes. PSE and Cascade rebates apply to different fuels, and the estimator already picks the best available amount for each upgrade. Income-qualified programs (HEAR, weatherization) can cover what’s left. The one rule: you can’t claim the same dollar twice from two programs for the same item.
Do I need natural gas to get rebates?
No — everyone in Whatcom has PSE for electricity, so the heat pump, water heater, window, EV charger, and recycling rebates are available regardless. Gas (Cascade) adds the furnace, door, and higher insulation rates. Switch off the gas toggle in the estimator to see your electric-only numbers.
What’s the single best first step?
Two calls: book the free PSE home energy assessment for a roadmap, and call the Opportunity Council (360-255-2192) to check if you qualify for free upgrades and the bill discount. Between them you’ll know exactly which programs are worth chasing.
