Review of A-1 Certified Service, Inc

Dear A-1 Certified, I want to take a moment to praise the exceptionally professional and proficient job that Ash, your technician, did during my service call today. As you probably know I have been a customer for many years and I have not always been satisfied with your service. On this occasion I can say that I am extremely pleased. Ash took the time to explain the work that she was doing and clearly demonstrated her outstanding knowledge of the equipment and its proper operation. Unlike previous visits from other technicians, Ash was very thorough and did not need to be reminded of any maintenance items to be performed. Ash is a great asset to your company and I hope that you are able to retain her for many years to come. Regards, Norman T. Ford mobile: 865.696.8998


Ash is an A-1 tech!




Review of A-1 Certified Service, Inc

Ash called before arriving, was spot on with her arrival time. She introduced herself when she arrived, said hello to our welcome committee Shitzhu, which is important to us ;) Briefed me on what she was going to be doing. She was extremely professional, polite & got to work right away. She went over paper work I needed to sign, explained everything checked out to be working properly & ook garbage filters with her. From what I could see, Ash did a great job! The pricing has nothing to do with Ash, that's determined in office.
