Our HVAC unit (outside unit thing, with the big fan... whatchumacallit) has an inch thick layer of ice on it, so we had to turn on the emergency heat setting so the unit wouldn't get messed up. I'm glad my husband knows about stuff because I have no clue about all that. He spent a few hours yesterday chopping firewood with my son, despite his 100% carpal tunnel and bad back, bless him. It's always good to have emergency firewood around for sure.
I definitely do not blame you for hunkering down and staying put while your truck is in the shop. I'm not going anywhere until I have to go back to work Tuesday night. Hopefully by then, the roads will be better. Our electric went off for a bit at some point during the night. I pray it doesn't go back off, because I have eggs in lockdown. It is so stressful hatching chicks during storms because you feel so helpless for them.
I pray everyone's electric stays on and the animals endure this cold okay.
