Premier Indoor Comfort Systems technician James Knox should be cloned. I have never met a more cordial, knowledgeable and friendly service person who personifies customer service. Premier should be proud that he represents there company with such honesty and dignity. Because of James I am now a full time customer of Premier. James took the time to show me where the problem was located and gave me a lesson on how my unit worked. His sense of caring and concern was unlike any other that I have dealt with in the service industry. Thanks James!!
