My Technician was right on time during the quoted time. Received a text message with picture of technician about 30minutes prior to his arrival. We did just a tune-up but the technician was really great at explaining what he was looking at and what I could do to keep an eye on my door's operation. Made good recommendations as to what we would want to upgrade in the future. Was professional in acknowledging our system was less than 2 years old but was also professional in pointing out where our door could develop troubles in the future. Without giving us the "salesman" pitch.
