Assess the home before adding materials
An energy assessment can identify insulation gaps, air leakage, duct problems and moisture concerns. An appropriate plan considers ventilation and combustion safety as well as comfort and efficiency.
Common improvements
- Attic or wall insulation suited to the construction and climate.
- Air sealing around appropriate penetrations and openings.
- Duct repair and sealing where leakage is identified.
- Weatherstripping and caulking where suitable.
- Radiant barriers only where an assessment and applicable program support them.
R-values and codes vary
Required insulation depends on the jurisdiction, building assembly and project. Existing depth alone does not establish R-value; material type and condition matter. Confirm local code and the program's specific requirements instead of using a statewide minimum.
Weatherization and utility funding
Income-qualified weatherization is different from an equipment rebate. Ask the administrator what work is provided, what costs you may owe and whether funding is open. Oncor reports its Low-Income Weatherization funding for 2026 is exhausted. Texas HEAR and HOMES have not launched, and 25C does not cover new 2026 installations.
Keep the required evidence
- Assessment and scope of work.
- Product specifications, installed R-value and covered area.
- Pre- and post-work testing if required.
- Invoices, photos and administrator approvals.
