And don't forget to tip your bartenders

It's starting to get cold at night and our furnace decided that it wasn't going to work. It would start for a few minutes but would never actually blow warm air through the vents. I know enough about it to take the cover off and read the LED error messages, but I certainly don't know how to fix a furnace. At least I didn't think I did. I changed the air filter and it is now toasty and warm in the house. So change your air filter if you haven't recently and then put your heating repair ad in the yellow pages.
