Coldest temps in 12 years

News here - yesterday the coldest day in 12 years - when I left the house yesterday morning it was -11F (-23C) and warmed up to a balmy 7F (-14C). This morning we work up to a VERY cold house.....and realized the furnace had gone out. I called a repair man and he was able to be here within 30 minutes. The blower on the furnace is out - so it is still making hot air, just not blowing it into the house. We are sitting by the fire in coats and hats. The repair man had to go to the supply house to get a new blower and will be back. It is going to be an expensive day!!!! Of course the furnace would go out on the coldest day in 12 years!!
