During the winter, the last thing you want to do is turn down your furnace to reduce your energy costs. While you might be able to put on more layers to feel warmer, you'll still feel freezing after you've taken a shower or early in the morning after you have woken up. However, there are fortunately other ways to stay warm while lowering your heating costs.
Inspect Your Ductwork
Make sure your ductwork is inspected to ensure that heat is not escaping from your home.
