Insulation and air-sealing rebates across the U.S.
Review published weatherization incentives and the audits, measurements, and installation rules that may apply. Start with your state, then verify the controlling program source before you commit.
The 2026 landscape, stated plainly
A project category can be eligible in one utility territory and unsupported across the street. These three layers must be checked separately.
State guides with published insulation & air sealing programs
Our current source set contains relevant published measures in 35 state guides. That is not a promise of universal eligibility or a complete market count; the program administrator makes the final determination.

What nationwide coverage means
The platform covers every state and organizes local program information. It does not turn a local utility offer into a nationwide entitlement, and it does not guarantee approval, funding, contractor availability, or savings.
Verify before you buy
- Document existing conditions before work begins.
- Air sealing and insulation may be treated as one package or separate measures.
- Program rules may require an approved contractor or post-install inspection.
Questions about Insulation & Air Sealing programs
Are insulation & air sealing rebates available in every state?
Not necessarily. Upgrade Rebates covers all 50 states, but published program availability varies by state, utility territory, customer, equipment, timing, and funding. This page currently routes to 35 state guides containing published program information for this category.
Can I rely on a displayed amount before I buy?
No. Treat every amount as a program summary, not an approval or guarantee. Confirm the current amount, budget, eligibility, pre-approval, equipment, contractor, and documentation rules with the administering agency or utility before purchase.
Are federal residential energy credits available for 2026 projects?
No. Sections 25C and 25D ended for qualifying property or expenditures after December 31, 2025. A state or utility program may still apply, depending on location and project.
Why is my state not in the program list below?
Every state has a guide, but not every guide currently contains a source-verified published measure for every project category. Use the full state directory to review your state's status and other available program information.
