Sunny but 5° when I left work.
Dunno what it's gonna be during the day but I'm sure it'll be 5° again when I leave for work.
At least my idea for the furnace is working. Kept tripping overtemp limit switch. Happens when the heat exchanger gets too hot and so it cuts the flame but leaves the induction motor and main fan running. So basically running A/C after every heat cycle because the induction motor is just cycling outside air through the heat exchanger while the fan is running to carry that cold air through the house. Takes too long for that switch to return to normal state and re fire the burner so while it's running almost continuously the house is still losing temp.
Normally when this happens it's a clogged air filter and/or my wife has covered up too many registers. I removed the endcap on one of the return lines in the basement, only about an 8x4 area basically like adding another return register. The furnace has cycled at least half as often and much shorter times. The house feels warmer overall too. At least more consistently warm. Hopefully that solves the issue for a while. Furnace is 6 years out of warranty, probably need to seriously consider a new one soonish.
