Weatherization Assistance Program (WAP) 2026: Free Home Energy Upgrades
The Weatherization Assistance Program is one of the most underused federal programs in America. It's been running since 1976, has weatherized over 7 million homes, and the Inflation Reduction Act tripled its funding. Yet most eligible households have never heard of it. If your income is below 200% of the federal poverty level, your home can get thousands of dollars in free energy upgrades.
What WAP covers
- Insulation: Attic, wall, and floor insulation to reduce heat loss
- Air sealing: Caulking, weatherstripping, sealing ductwork, fixing air leaks
- Heating system repair/replacement: Furnace tune-up, repair, or full replacement if unsafe or inefficient
- Cooling system improvements: In hot climates, AC repair or whole-house fans
- Water heater insulation: Wrapping water heaters and hot water pipes
- Window and door repairs: Sealing or replacing if severely damaged
- Health and safety: Carbon monoxide detectors, ventilation improvements, electrical repairs related to safety
The specific improvements are determined by a home energy audit conducted by WAP technicians. They test your home with blower door tests and infrared cameras to identify where energy is being wasted, then prioritize improvements by cost-effectiveness.
Eligibility
| Household Size | 200% Poverty Level (2026) |
|---|---|
| 1 person | $30,120 |
| 2 people | $40,880 |
| 3 people | $51,640 |
| 4 people | $62,400 |
| 5 people | $73,160 |
Priority is given to households with elderly residents (60+), people with disabilities, families with children under 6, and households with the highest energy burden (energy costs as a percentage of income).
How to apply
- Find your local WAP provider: Visit energy.gov/eere/wap/where-apply or call your state energy office
- Submit application with proof of income (tax returns, pay stubs, or benefit award letters)
- Wait for eligibility determination (2-8 weeks depending on state)
- Home energy audit scheduled (WAP technicians visit your home)
- Improvements installed (typically 1-3 days of work)
- Post-installation inspection to verify quality
Wait times vary dramatically by state and funding availability. Some states have waitlists of 3-6 months. The IRA's additional $3.5 billion in funding has reduced wait times in many areas, but demand remains high.

WAP vs other energy programs
WAP is separate from the IRA's HOMES and HEAR rebate programs, though they serve overlapping populations. Key difference: WAP is fully free (no copay), while HEAR rebates cover up to 100% of costs for low-income households but may require some coordination. In many states, WAP agencies are also administering HEAR rebates, creating a one-stop-shop for low-income energy upgrades.
If you qualify for WAP, also ask about the HEAR rebate program — you may be eligible for additional free upgrades (heat pump, electric stove, electric panel) beyond what WAP covers.
