Brrrr...

For the third straight year we're experiencing furnace trouble. How can someone have a heating problem every year? We have always turned the heat down pretty darn low at night. Troy puts off a lot of heat naturally, and leaving it above 60 at night with him laying next to me makes me want to open a window. Who cares that it's 20 degrees outside? So do you think turning it up/down 15 degrees at a time might have something to do with it? Because seriously...3 years in a row? We've even been in two different houses during that time. It's got to be us.
