I noticed it last night, but, of course they couldn't get a tech out to us immediately.

And, of course, of course, we had a light frost overnight.

Fortunately, our house is well insulated.

I woke up to a 60°F house.

Brrr.
Good luck with a speedy repair.
(Go back to bed - warmer there).

Drat. I hope it can be repaired quickly, for a reasonable price!

That sucks. With us it only ever happened on Friday evenings. Good luck!
