The service technician, Frank, was very professional with a high standard of workmanship and customer service. He was on time and had taken his time to explain any questions that I may of had. I was impressed from the start when he covered my floor and fireplace with clean drop cloths before starting the work. I must say that this was truly A1 service from an A1 person. I am sure that his work ethic is an example of the companies business model.
