You might want to see if there's an air leak around your furnace. Strong winds outside can have enough force to make a breeze where it normally wouldn't, though. Also, newer furnaces usually have an automatic pilot light, so not having one is an indicator that it's probably an older furnace. | |

I once woke up to a 50-degree apartment because the pilot light went out (even with the heat on), but re-lighting it did the trick. It also went out earlier this year without explanation during the summer months, and I had tremendous difficulty getting it to stay lit past a few seconds. | |
