Arizona Window Rebates in 2026: Current SRP, APS, and Federal Status

Window incentive information changes, and older Arizona guides can remain in search results after programs end. This page summarizes what we could verify from official sources on July 27, 2026. Confirm eligibility directly with the utility or tax authority before ordering products or relying on an incentive in a project budget.

SRP Rebate for Replacement Windows

SRP currently publishes a $3 per square foot rebate for qualifying replacement windows in eligible existing residences. The currently published program requires professionally installed ENERGY STAR replacement windows with a U factor of 0.32 or lower and a Solar Heat Gain Coefficient (SHGC) of 0.23 or lower.

The application also requires the product's NFRC Certified Product Directory number and an installer licensed in Arizona. Under the currently published terms, installation must occur before April 30, 2027, and the application must be submitted within six months of installation. SRP controls final eligibility and payment.

APS Status for Replacement Windows

We did not find a current official APS source supporting the older claims of up to $125 per replacement window or $1,000 per project. Those figures have been removed from this guide. APS currently publishes other offers related to energy savings through its marketplace and program pages, but homeowners should not assume that an ENERGY STAR replacement window qualifies for an APS rebate.

APS customers should check the current APS Marketplace and APS energy efficiency pages or contact APS before purchasing. If APS publishes a new program for replacement windows, use the official program terms rather than archived summaries or summaries from other publishers.

Federal Window Credit Ended for 2026 Projects

The IRS states that the Energy Efficient Home Improvement Credit applies to qualifying property placed in service before December 31, 2025. It should not be presented as an available federal window credit for property placed in service during 2026.

Homeowners evaluating earlier tax years should use IRS guidance and a qualified tax professional. Arizona's Window Company does not provide tax advice and does not determine eligibility for a tax credit.

Documentation to Collect

Avoid Counting the Same Savings Twice

Do not add an unverified APS rebate, an expired federal credit, and estimated utility bill savings into a guaranteed project return. Product performance, home orientation, HVAC condition, occupant behavior, utility rates, and installation quality all affect actual energy use.
