The Texas Weatherization Assistance Program (WAP) is a no-cost program for income-qualified households, administered by the Texas Department of Housing and Community Affairs (TDHCA) with federal funding from the U.S. Department of Energy and the HHS Low Income Home Energy Assistance Program (LIHEAP). Unlike a utility rebate, WAP is not a payment back to the homeowner — it pays for the work directly for eligible households, at no cost to them.
WAP's covered measures include ductwork and the tune-up, repair, or replacement of energy-inefficient heating and cooling systems, along with caulking, weather-stripping, added insulation, and sealing holes in the building envelope. The specific work is decided by an energy audit of the home rather than chosen from a menu, so an eligible household might receive duct sealing and an HVAC repair, or a fuller package, depending on what the audit finds. Eligibility is generally tied to household income at or below about 200% of the Federal Poverty Guidelines, with the exact threshold set each year; households already receiving benefits like SNAP or SSI may qualify automatically.
The program is statewide, including Corpus Christi and Nueces County, but it is delivered locally: TDHCA passes funding to Community Action Agencies and other subrecipients that handle applications, audits, and the work. Apply through the Community Action Agency that serves your county rather than through the state directly. Because the program is funding-limited and income-qualified, it is worth applying early. For a homeowner who does not qualify for WAP, the AEP Texas Residential Standard Offer Program covers efficiency measures like duct sealing for the general market.
