"Most folks in older homes have the old mercury switch thermostats and they don't really think about upgrading to a programmable thermostat and I think that's primarily because they think it's going to be expensive, it's going to be difficult to do, and it's neither of those things."
Another tip is to use natural, ambient light during the day to help heat the house and to close blinds at night to keep cold air out. Allen says another way to save money is to close your fireplace damper between uses. Keeping it open when you don't have a fire is a bad idea.
"You're literally throwing your money up the chimney and out the door at that point. So it's important that you make sure that you close that damper, especially at the end of the heating season when you're no longer going to be using that fireplace so you don't experience the same problem all year round and as you know, in our climate, air-conditioning dominates it most of the year."
He says using LED Christmas lights and putting them on a timer will also save money this winter.
