It took a few days and a bit of trial and error, but so far the problem ( periodic on-off heating) seems to have been rectified. Both service technicians explained the issue, and provided choices to rectify the problem. As I said, it took a couple trips, but so far, so good. We have dealt with Fairview for 20+ years, always with satisfactory results
