The Weatherization Assistance Program, often called WAP, helps eligible low-income households improve home energy efficiency. To check eligibility, start with the U.S. Department of Energy program page, then follow your state or local weatherization agency’s intake instructions.

What weatherization can include
| Area | Possible service | Important limit |
|---|---|---|
| Energy audit | Home assessment to identify cost-effective improvements | Services depend on local program rules. |
| Air sealing and insulation | Measures that reduce heating or cooling loss | Not every home receives every measure. |
| Heating or cooling systems | Safety and efficiency-related repairs in some cases | Major replacement rules vary by agency. |
| Health and safety | Checks tied to weatherization work | Some problems must be corrected first. |
| Referrals | Connections to other energy or utility programs | Separate applications may be required. |
How to check eligibility
- Open the official DOE Weatherization Assistance Program page.
- Use the how-to-apply information to find your state or local agency.
- Check income rules, priority groups, renter rules, and document requirements.
- Ask whether LIHEAP approval helps with referral or eligibility in your area.
- Confirm whether there is a waitlist and what happens after application.
- Keep copies of any confirmation number, agency name, and requested documents.
Weatherization is not a rebate coupon
WAP is usually delivered through approved agencies and contractors after eligibility review and home assessment. It is different from a simple appliance rebate or tax credit. Do not pay a private company that claims it can guarantee free weatherization without an official agency path.
Good questions before applying
- Is the program currently accepting applications?
- Which income table and household-size rules apply?

FAQ
Is WAP the same as LIHEAP?
No. They are related energy-assistance programs, but applications, services, and eligibility pathways can differ.
Can renters apply for weatherization?
Often yes, but local rules and landlord permission may apply.
Will weatherization pay for every home repair?
No. Weatherization focuses on eligible energy-efficiency and health-safety measures, not every repair.
