Texas homeowners use significantly more electricity than the national average—often exceeding 1,500 kWh per month during the summer. While we love to blame ERCOT and the retail energy providers, the real culprit is sitting directly above your ceiling drywall.
The Three Pillars of Energy Waste
-
1. The 140°F Furnace Above Your Head
During July, the Texas sun bakes dark asphalt roofs. Without a Radiant Barrier or heavy R-49 insulation, that 140°F heat presses directly down into your 72°F living space. Your AC has to fight a 70-degree temperature differential constantly.

2. Leaky Ductwork in the Attic
Most DFW homes have their AC equipment and flexible ductwork routed through the unconditioned attic. If the duct seams are poorly sealed, the AC is literally pumping freezing 55°F air directly into the 140°F attic abyss, while simultaneously sucking in hot, dusty attic air into your bedrooms.

3. Variable Rate Exposure
If you are on an indexed or variable-rate plan, wholesale electricity prices spike dramatically at 4:00 PM when the grid enters tight-supply conditions. If your house has zero thermal mass (poor insulation), your AC must run explicitly during the most expensive hours of the day just to survive the afternoon heat.
"You cannot out-cool a thermal leak."
No matter how efficient your 20-SEER AC unit is, if the thermal envelope of the house is hollow, the energy simply leaks out the roof.
