Tech arrived at 12:45 for a 12:00 - 2:00PM window. He was pleasant and listened carefully while we talked about the A/C system. He set about his work quietly and carefully and provided updates as he moved from location to location of the different parts of the system. He presented the service options we had clearly and patiently to ensure we were making a good decision. He made this service call less stressful than it could have been with his personality. Thank you.
