There are a couple of guys banging around in the garage, the old unit is out, and they are putting in new ducts to vent the replacement, which is smaller in size, but the same output in BTUs.
They scheduled two days for the job, which means we probably won't have heat tonight. Looks like the weather prediction is for high thirties tonight, so not so bad if we keep the house buttoned up.
I have logs for the fireplace and the little electric portable heater standing by ...
EDITOR'S NOTE: Evening has come and the furnace folk are gone, but they managed to get the system working enough so we'll have heat tonight.
My daughter-in-law came by and lent us some portable propane heaters they got during a power failure last winter, and between those and the fireplace and extra blankets, we could have kept the houseplants and the dogs and ourselves from freezing, but it's good that we don't have to do it that way. Onward and upward.
