I had gone out for lunch with friends and my sister, when we got home, the AC was out. It was 4:00 p. m. I called Global AC and by 4:15 a technician was knocking at my door! He introduced himself as Domingo and immediately got to work on the unit. He was persistent until he found the problem. Made suggestions for us and we couldn’t be happier! Thank you, Domingo, for your service!
