Sunday the furnace decided to take a break. Would come on for about a minute, turn off and refuse to anything else. A recurring and known issue with our furnace, due to flame detector failure as buildup occurs. Bailey was here 30 min. after initial call. He called to give an estimate for arrival, then called a second time to update that due to being stopped by a train (as to be expected in TH).
Got here, fixed the issue, and then went ahead and did our Plan C tune up a bit ahead of schedule.
Good work, on time, kept up to date, and kept me informed.
