Spokane home energy rebates at a glance
We read Avista's Washington rebate pages, the State Department of Commerce page and the state solar tax law on October 6, 2026. Avista rebates only count for equipment that runs on Avista electric or natural gas service, so look at your bills first.
Insulation
For attics, floors and walls that start thin. No income test. An approved installer does a free assessment and takes the rebate off your bill.
Windows and sliding doors
$180 or $225 per window and $480 or $600 per sliding glass door with a contractor, depending on the U-factor rating.
Free weatherization
For income-qualifying Avista customers. Upgrades can include insulation, air sealing and door and window work.
Solar
Washington exempts solar equipment and installation from sales tax through 2029 for systems up to 100 kilowatts. We did not read an Avista solar rebate.
What is not here
The federal clean energy credit ended for 2026 installs. We did not find an Avista rebate for batteries or EV chargers on its single-family page. The state lists Spokane County as a partner for its home electrification rebates for households at or below 150 percent of area median income, with a $630,000 award, but the state page shows no dollar amount per household.
Spokane homes in numbers
The US Census Bureau's American Community Survey (2020 to 2024) counts 102,834 homes in Spokane. About 59 percent of households own and 41 percent rent, and 64 percent of homes are detached houses. This is an older city. About 68 percent of homes were built before 1980 and 26 percent before 1940, while only about 16 percent were built in 2000 or later.
Gas is the main heating fuel for about 54 percent of homes, electricity for 42 percent, and heating oil for about 1 percent. That split is why Avista's mix matters. Avista pays on both electric and gas homes, and its insulation and window rebates work for either.
Why insulation and windows lead
Old houses often have little insulation and drafty single-pane windows. Avista's insulation rebate pays more for thinner starting levels, so an old attic with R-11 or less may get the full $1.75 per square foot, and a newer home may get nothing. Avista says only 10 to 30 percent of homes in its area qualify based on current insulation, which is why the assessment comes first. The windows rebate pays more for tighter windows, and you have 120 days after installation to apply.
Heat pumps work differently here
Avista does not send a check for a heat pump. The discount goes to your contractor through a supplier, and the contractor may pass it on. We cover this on our Spokane heat pump page. For a gas home, remember the rule that rebates only count for equipment that runs on Avista service. Read our Avista guide for the full tables.
Every rebate guide for Spokane
Where to start in Spokane
- Check that Avista sends your electric or gas bill.
- Book the free insulation assessment first, since it can lead to a no-cost project for some homes.
- Price windows with the U-factor on each quote and keep the final invoice for the rebate form.
- Ask heat pump contractors to show the Avista discount on the bid.
- If your household income is at or below 150 percent of area median income, ask Spokane County about state-funded rebates and Avista about free weatherization.

What rebates does Avista offer in Spokane?
On our October 6, 2026 reading: $1.75 per square foot for insulation, up to $225 per window, a $300 to $600 heat pump discount and a $500 heat pump water heater discount. Income-qualifying customers can get free weatherization.
Does Avista have an income limit?
The insulation program has none. The free weatherization program is for income-qualifying customers.
Is there a Spokane solar rebate?
We did not read one. Washington exempts solar equipment and installation from sales tax through 2029 for systems up to 100 kilowatts.
Can renters apply?
Avista's single-family pages do not say whether renters can claim, so ask Avista first. The state's home electrification rebates are open to renters at or below 150 percent of area median income through local partners such as Spokane County.
Is there a federal tax credit?
No. The IRS says the residential clean energy credit does not apply to property placed in service after December 31, 2025.
