Came home to a HOT house on a Friday night, called S'dale AC at 9PM, spoke to the answering service. Scottsdale AC called back at 8:30AM Sat morning to say they would be here at 9AM, which they were. Hector said it was the capacitor, which was covered under my warranty, so I only had to pay for the weekend visit. He did the job and I am now cool.
