Horrible. The Home warranty company sent them out. They sent, Ryan. Ryan came in the house looked at the t-stat and said the AC was fine. He never looked at any of the AC equipment. He was here a total of 5 minutes. Right after he left, the AC quit working again. I called 5 star and explained to them that we have a one week old baby, and must have AC. Five star said they would send some one over after 4:00pm. At 4:30pm, I called and no one at five star would answer the phone. I called Ryan and he said, I was not on the list and he was not coming over. I then had to pay another company to come out a fix my AC. It was the motor,when cool it would run for a few minutes before it overheated and turned off. The best part is that Carla called me to ask for the $45.00 Ryan did not pick up. While Carla was very nice when I explained what happened, the communication and customer service was awful.
