Texas's extreme summer heat, sprawling homes, and high cooling costs create enormous potential for energy savings. A professional energy audit identifies where your home loses conditioned air and where equipment operates inefficiently.

Texas-Specific Considerations
Extreme Heat Focus
Texas audits emphasize cooling-related improvements:
- Attic insulation (the #1 energy improvement for Texas homes)
- Radiant barriers (reflect 95% of radiant heat in attics — especially effective in Texas)
- Duct sealing (Texas homes lose 20-40% of cooled air through duct leaks)
- HVAC efficiency (right-sizing prevents over-cooling and cycling)
- Window treatments and solar screens
Texas Deregulated Energy Market
In deregulated areas (most of Texas), energy prices vary by provider. An energy audit helps you understand true consumption so you can choose the most cost-effective electricity plan. Average Texas electricity costs: $0.12-$0.18/kWh (among the highest for cooling-heavy usage).
Weatherization Assistance
Texas Department of Housing and Community Affairs offers free weatherization for income-eligible households, including energy assessments and improvements.
Frequently Asked Questions
How much does an energy audit cost in Texas?
Comprehensive audits cost $200-$500. Some Texas utilities offer free basic assessments. For HERS ratings, expect $400-$700.
What is the biggest energy waste in Texas homes?
Air leakage and inadequate attic insulation are the top two issues. Texas attics can reach 150°F+ in summer, and insufficient insulation allows that heat to radiate into living spaces. Duct leaks in unconditioned attics compound the problem.
Are there energy rebates available in Texas?
Yes. CPS Energy (San Antonio), Austin Energy, and Oncor offer various rebates for insulation, HVAC, and smart thermostats. Federal heat pump tax credits ($2,000) remain available through 2032.
How much can I save after a Texas energy audit?
The average Texas household can save $400-$1,200 annually by implementing audit recommendations. Attic insulation alone can save $200-$600/year on cooling costs.
How do I find a certified energy auditor in Texas?
Search the BPI certified professional directory at bpi.org or the RESNET directory at resnet.us. Verify that the auditor holds current certifications and has experience with Texas homes.
