Our air conditioner stopped working in the middle of the night. We called Perfect Star and they had a technician at the house by 12:30 with the air conditioner diagnosed and up and running within the hour. It was really appreciated since today is going to be 106 degrees. Our technician, Ray, was friendly, knowledgeable and efficient. He also gave me some tips to keep the AC running efficiently. I also appreciate companies that wear booties over their shoes in the house. I highly recommend Perfect Star. Thanks Ray!
