I appreciate that Jack Lehr takes the initiative to schedule and notify me when it is time for service. The technician Ryan was very good. I bought the leak detector on this visit. Paid $144 and later was advised by a friend he had purchased the same device from Home Depot for $38. Obviously I felt I had paid an unfair price and it left me with doubts about future service and what I might be charged for replacement parts. I'm willing to pay for parts with fair mark ups but I don't want to be taken advantage of. Fortunately your customer service person is sending me a refund however I will be paying attention to this in the future. Thank you. Randy Dreher
