A problem in Alabama is houses built in the past 20 years are largely designed assuming mild winters and warm summers. Thus they have vaulted ceilings and lot of windows. When a cold snap hits these newer homes are poorly designed and can't handle it - like our house. I'm sitting here typing right now and the ceiling is about 15 feet above me while sitting. So I am heating all that wasted space even though I have lots of ceiling fans. Plus all those windows and their lousy insulation.
