The last time one of Casteel's technicians came out he would not get off the phone with his ex wife. I couldn't even ask him questions because he was on the phone the entire time! Then he was in a hurry to leave. His estimate was extremely high and we were able to get the same service else where for $1k cheaper. The previous 2 years that I had this company service my unit, they cleaned the inside of the of my unit - this time I had to ask the guy 3 times to was the unit and he still tried to leave without doing it. What a NIGHTMARE! Then I sent in a comment card and called about the awful service and did not get a response back from them. They keep sending me junk mail despite the fact that I've told them I will NEVER do business with them again.
