Worked example: one Arizona home
Take 1,000 square feet of attic insulation across 2 large zones, on a project that costs $5,000, in a home heated with natural gas. These are example inputs, not typical prices. Each program's own rule gives the amounts below; where one program has several tiers only the largest one counts, separate programs add up, and a percentage offer with no cost entered is shown at its ceiling.
| Utility | Not income-qualified | Moderate income | Low income |
|---|---|---|---|
| Salt River Project (SRP) | $600 | $600 | $600 |
For a household that is not income-qualified, the example comes to $600, made of $600 from SRP insulation. None of the open offers has a separate income-qualified amount, so every household gets the same figure.
Who can use these Arizona offers
Every household in Arizona covered by SRP can apply; the offers are not limited to one utility's territory. None of these program pages lists an end date, and each can change or stop while funds last.
Federal credit and state IRA rebates
The Energy Efficient Home Improvement Credit (IRC §25C) paid 30% of insulation and air-sealing materials, within the $1,200 annual limit (labor not included). The IRS page says: “can claim the credit for improvements made through December 31, 2025.” Not allowed for property placed in service after December 31, 2025. Source: IRS: Energy Efficient Home Improvement Credit, 26 U.S.C. §25C, as amended by Public Law 119-21 (July 4, 2025). See what the credit covered and when it ended.
Arizona's Inflation Reduction Act home energy rebate page was not reached on the last check, so its status is not shown here. The federal status page lists every state whose status was read.
