I told you about our furnace failing to heat last Sunday. At 5 PM on Monday, my in-law Gene King came over to look at it. He figured that the problem was just a dirty sensor, which should be easy to fix. However, he couldn’t find anything wrong with the furnace; it worked just fine when I turned the thermostat back on. We joked that maybe the furnace heard Gene was coming, so it’s behaving itself now; Gene’s handyman reputation preceded him!
At any rate, we did not need to run any heating on Tuesday; it was so mild that I was out for both the afternoon and evening, without needing a jacket. Today the weather changed abruptly, though. A cold front came in at 7 AM, with a thunderstorm announcing its arrival. The lighting quickly passed, but it rained for most of the morning and afternoon. After the rain let up, I stepped outside to run today’s errands, and was astonished at how cold it got—it couldn’t have been more than 40 degrees. Now the forecast is calling for a low of 36 tonight, and there is even a frost warning. After moving to Kentucky, I learned that the last possible day of frost around here is May 3, compared with February 18 in central Florida; still, in the nearly seven years since our arrival, this is the first time we got spring frost later than early April.
As expected, the furnace came on again this evening. Although it is delivering heat, it doesn’t seem to be running for as long in each cycle as it did before Sunday’s trouble started. I’ll have to listen for a while before I’m convinced it is working all right.
