I don't recall being unsatisfied with any of technicians who have come to the house from enercare, but will say that the most recent technician (Alphonso) stood out as the best we have had. He was very friendly, followed the Covid guidelines. Came for an annual inspection but saw a major problem with the furnace, explained what was happening and then went ahead and fixed it. He was here for over 2 hours and did a very thorough job. Left everything neat and tidy. Couldn't have asked for anything more from the guy. He was great.
