Home Insulation Program
Tired of chilly drafts in winter or hot spots in summer?
Adding insulation and sealing air leaks can help keep your home more comfortable. It reduces hot and cold spots and helps stop drafts from hidden gaps in attics, walls, and crawl spaces. That means lower energy bills and a cozier home year-round. And with our trusted installers, installation and paperwork are taken care of for you.
Through Avista's Home Insulation Program, eligible customers can receive rebates for insulation improvements in attics, walls, floors, crawl spaces, and ductwork.
More customers now qualify for free or reduced-cost insulation
We've updated our program requirements, which means homes with more existing insulation may now be eligible.
In some cases, additional funding may cover the full cost of insulation upgrades. A participating contractor can review your home and explain which rebates, incentives, and no-cost options may be available to you.
Here’s how it works:
- Schedule your free assessment
Our trusted insulation partner will review your eligibility and explain any out of pocket costs. - Upgrade your insulation
If eligible, and you choose to proceed, our trusted partner will install your new insulation. - Get your instant rebate
Rebates* will be applied upfront to the cost of your upgrade, so you don't have to wait!

Some homes may qualify for no-cost insulation upgrades
As part of Avista's clean energy work, we're helping bring energy-saving improvements to customers in underserved communities, known as Named Communities.
Additional funding is available to help eligible households lower energy use, improve home comfort, and reduce energy bills. The Named Communities Investment Fund (NCIF) supports projects that benefit Washington electric customers in these communities. Projects for natural gas customers may also receive support from Washington's Climate Commitment Act (CCA), which aims to reduce greenhouse gas emissions.
If your home qualifies, available funding may cover the full cost of your insulation project, meaning you pay nothing out of pocket.
A participating contractor can determine whether your home is eligible and explain available funding during your home assessment.
Reduced-cost insulation upgrades
If you don't qualify for a no-cost project, you may still be eligible for a Home Insulation Program rebate. (See list below.)
The incentive is applied directly to the project cost, helping reduce the amount you pay out of pocket. For example, a home with 1,200 square feet of qualifying insulation could receive a rebate of about $2,100.
To qualify for our Home Insulation Program, you must:
- Be an existing Avista residential customer
- Be applying for your primary residence in an existing single family, duplex, triplex or fourplex home
- New construction does not qualify
- Meet pre-existing and post-projects insulation levels (R-values)
- Washington customers: Heat your home with Avista electricity or natural gas via electric or natural gas furnace, natural gas boiler, electric cadet (wall heater), radiant heating, baseboards or heat pump
- Idaho customers: Heat your home with Avista electricity via electric furnace, electric cadet (wall heater), radiant heating, baseboards or heat pump
This program does not require income qualifications. All eligible customers can apply.
The estimate you receive from your contractor will include the R-value of your existing insulation and the new R-value if additional insulation is recommended. Requirements may vary for customers in Avista's Named Communities. Your contractor will know which values apply to your home.
