A Texas Summer Story It was 101° in Irving when the call came in. A young family’s AC had quit in the middle of the night. This was about 36 hours before I got there. The attic felt like a sauna, the kids were sweating, and every other company they’d called told them the same thing — “You probably need a new system because this thing is 16 years old.” When we showed up, it took ten minutes to find the real issue: a $345 capacitor.
