Darren arrived on time and was very professional, explaining things about my unit I hadn't know before. He was working for quite a while. He didn't just poke around and leave. The service fees were more than I expected, but I believe you get what you pay for and that's what happened. I happen to listen to Louis Bruno's commercials and also his Saturday morning radio show. Mr. Bruno is a teacher as well as a salesman. I am very happy with the service I received and I will continue to have Bruno's services.
