Why AC Breaks Down in Dallas
Dallas runs air conditioning seven months a year. From June through September, the metroplex averages highs between 96 and 107 degrees, and systems run nearly continuously for four straight months. The equipment lives where the heat is worst — in the attic, where temperatures reach 140 to 160 degrees even when the outdoor air is only 100.
That kind of sustained load wears out capacitors, burns out compressor windings, and pushes refrigerant systems past their design limits. The homes most at risk are pre-1980 construction — and Dallas has a lot of it — with undersized ductwork, poor insulation, and systems that were never designed for the loads modern Texas summers demand.
The parts that fail most often are capacitors, contactors, fan motors and control boards, and most of those repairs are finished in one visit. When a system is beyond repair, the replacement should be sized the replacement correctly for your home and your ductwork, not just the tonnage the old unit happened to be.
