Top Energy-Saving Tips for Texas Homeowners (2026)
1. Upgrade Attic Insulation to R-49
Most Texas homes built before 2010 have R-19 to R-30 attic insulation — well below the current R-38 to R-49 recommendation. Adding 6 to 10 inches of blown-in insulation typically pays for itself in 3 years through summer AC savings.
2. Seal and Clean Air Ducts
EnergyStar estimates 20–30% of conditioned air is lost through duct leaks in a typical home. Professional duct sealing plus NADCA cleaning restores full airflow, reduces HVAC runtime, and lowers indoor allergens.
3. Install a Radiant Barrier
A radiant barrier stapled to the underside of the roof deck reflects up to 97% of radiant heat, keeping attic temperatures 20–30°F cooler in Texas summers. This alone can cut cooling costs 10–15%.
4. Clean the Dryer Vent
A clogged dryer vent forces the dryer to run 2–3x longer per load. Annual cleaning saves an average of $18–$24 per month in gas or electric costs while eliminating a fire hazard.
5. Service Your Chimney and Fireplace
A properly sealed damper and cap prevents conditioned air from escaping year-round. In Dallas, a leaky damper can cost $200+ per year in wasted heating and cooling.
