The Weatherization Assistance Program (WAP) is a U.S. Department of Energy program administered in Texas by the Texas Department of Housing & Community Affairs (TDHCA) through local sub-recipient agencies. It provides free home weatherization to income-qualified households.

For duct work specifically, WAP's covered measures include duct sealing and repair — addressing the leaks that waste conditioned air — along with insulation, air sealing, and health-and-safety HVAC work. A program auditor inspects the home and selects the measures; the household pays nothing.

Because funding is limited and demand is high, there's usually a waitlist. Apply through the local sub-recipient agency for your county; in the Coastal Bend that's the community action agency serving Corpus Christi and Nueces County.

Who qualifies

Texas household with income at or below the program limit (commonly 200% of the federal poverty level — check current limits).
Both homeowners and renters can qualify (renters need owner consent).
An energy audit determines the measures; duct sealing and repair are covered alongside insulation, air sealing, and HVAC work.
Priority is typically given to elderly residents, people with disabilities, and families with young children.

How to apply

Confirm current program-year details with the utility before installing — amounts, deadlines, and qualifying equipment lists change yearly.
