Why Dallas Summers Are So Expensive
Extreme attic temperatures
DFW attics regularly reach 130–150°F in summer. That's a massive heat source sitting directly above your living space, radiating heat down through your ceiling 24 hours a day.
Long cooling season
DFW AC season runs roughly March through November — 8 to 9 months. Any inefficiency in your home's thermal envelope compounds over hundreds of hours of runtime.
Aging insulation
Most DFW homes were built in the 1980s–2000s with insulation standards far below today's DOE recommendations. R-19 was common then. R-49 is recommended now. That gap costs money every single day.
What Actually Lowers Your Bill
Ranked by impact and cost-effectiveness for DFW homes:
Upgrade Attic Insulation to R-49
The highest-ROI upgrade for most DFW homes. Bringing your attic from R-19 to R-49 with blown-in insulation dramatically reduces heat transfer into your living space. Most jobs complete in one day.
Add a Radiant Barrier
Reflects up to 97% of radiant heat at the roof deck before it enters your attic. Combined with upgraded insulation, total savings reach 15–25%. Best ROI in hot, sunny climates like DFW.
Seal Air Leaks (Spray Foam)
If your home has significant air leakage — gaps around pipes, wiring, and framing — spray foam insulation seals and insulates simultaneously. Best for new construction or older homes with poor air sealing.
Clean Your Air Ducts
Dirty ducts restrict airflow and force your HVAC to work harder. In DFW where AC runs nearly year-round, clean ducts help your system move conditioned air more efficiently.
