Seems tonight will be the coldest night so far. A who neighborhood in my city is without gas due to a construction crew breaking a line. I started to think, I have a gas furnace and no backup system, I am very unprepared in this area. How long will an average house stay warm in zero degree weather? What kind of backup system could you have in a city house? Is it safe to stay in a vehicle with the engine running? Etc. Anyone have thoughts there.
I had a close call last night, about 2:30 the blower fan in my furnace began to squeal loud enough to wake me up. Killed power to the furnace and pulled the blower out and it was hard to turn by hand. I used a plain old bendable straw to dip in a quart of Mobile 1 5w30 engine oil and drop a bit in the bearings and got it loosened up and running again, in fact its running better than ever.
