I had a great experience with Caleb at Patterson. My air conditioner stopped working Sunday afternoon. I took a chance and called on Sunday night and someone answered the phone and put in a service call. Caleb and his assistant had a cancelation and were at my house by about 9:30. They worked all day long but had it up and running by about 3:00. They were both very clean and courteous to me. They were very careful not to track any dirt into my house. Thank you so much for the excellent service.
