I assure you, I am not that energy conscious. Nor that cheap.
My dad was that cheap. He removed the furnace from his house entirely and got through the Midwestern winters by wearing his overcoat constantly and running space heaters in closed rooms. He swore he wasn't going to give the gas company any more than he absolutely had to.
I, too, economize on energy. But not that much. I routinely set the thermostat back to 55 degrees at night and stay warm and cozy under five covers and three cats. But by 8:37 in the morning I really do expect the temperature to be heading back up towards 61.
Wednesday morning, the thermostat said 53 degrees when I got up, but the furnace straightened itself out. Probably had nothing to do with the fiddling I did with the fan switch.
Thursday morning was a bit warmer outside: no trouble with the heat.
Friday morning, yesterday, the outside temps dove back into the mid-20s. And my thermostat read 52 degrees. Then 51.
I called the home warranty people, who had a heating and cooling repair company call me. Yes, sir, the furnace motor is going. No, sir, the fan and the gas burner are not running. Yes, sir, the pilot light is on. No, sir, I can't seem to find the switch for the furnace motor. Yes, sir, I've found the label inside the furnace . . . oh, look, I think it says this unit was installed in 1987! No, sir, that is really not surprising, it was my POs-1 who put in the forced air system . . . No, sir, I still haven't found the switch you describe . . . oh! look! the burner and the fan just came on!
That's good, the heating guy said, because they were pretty booked up that day. Call them back on Monday to let them know if they should still come out.
I did not wait till Monday. Not with the thermostat reading 46 degrees F. Not with it again in the 20s outside. A number of calls and some futile fiddling with switches later, the maintenance guy has determined the problem is the module. Which he can't get till Monday. And hopefully it's not some other part I forget the name of: that'd mean replacing the whole furnace.
(Though given that I have a replacement warranty, that might not be a bad thing. Even the sort of bog-standard furnace the home warranty company will pay for has got to be more energy-efficient than the unit I've got!)
Meanwhile, I get to rough it through the weekend and most of Monday. Baking Christmas cookies was not on today's calendar. But, um, I think I just changed my plans . . .
