Quick answer: The Weatherization Assistance Program (WAP) offers free energy-efficiency improvements to households earning at or below 200% of the poverty guidelines. You apply through your local weatherization agency.
What is the Weatherization Assistance Program?
The Weatherization Assistance Program, funded by the U.S. Department of Energy, makes free energy-efficiency improvements to homes. These upgrades reduce your heating and cooling costs and make your home more comfortable.
Common improvements include:
- Insulation in attics, walls and crawl spaces
- Air sealing to stop drafts and leaks
- Repairs to heating and cooling systems
- Weather stripping and caulking
Who can qualify
Your household may qualify if your income is at or below 200% of the poverty guidelines for your family size. For 2026, here are the limits for the contiguous United States:
| Family size | Annual income limit |
|---|---|
| 1 person | $31,920 |
| 2 people | $43,280 |
| 3 people | $54,640 |
| 4 people | $66,000 |
| 5 people | $77,360 |
| 6 people | $88,720 |
| 7 people | $100,080 |

Higher income limits apply in Alaska and Hawaii. Households receiving SSI (Supplemental Security Income) or TANF (Temporary Assistance for Needy Families) can qualify automatically.
Priority often goes to:
- Older adults
- People with disabilities
- Families with children
- Households with high energy bills
How to apply
You apply directly through your local weatherization agency, not through a state or federal office. You can search for your local agency on the Department of Energy's website.
When you apply, be ready to share:
- Proof of income (recent pay stubs, tax returns, or benefit statements)
- Proof of citizenship or legal residency
- Utility bills
- Information about your home (age, type of heating system, etc.)
Applying is free. Only the local weatherization agency decides whether you qualify.
Special rules for renters
If you rent your home, you usually need your landlord's written permission to have weatherization work done. Ask your landlord before you apply.
What to expect
Once approved, a local contractor will inspect your home and recommend upgrades. The work is done at no cost to you. The improvements are permanent, so you benefit from lower energy bills even if you move.
The time from application to completed work varies by location. Your local agency can tell you how long it typically takes in your area.
Frequently asked questions
