My AC failed during the hottest days, I called all the numbers. Only Superior Mechanical Service is willing to put me in their jam-packed schedule and come to look at my AC the next day. The technician is earlier than the scheduled time which I am glad. He do call me ahead to let me know when he will arrive. He is friendly and helpful. I am glad that I call Superior Mechanical Services, otherwise, I might have to wait until next week to get my AC back to work.
