If your home has single-pane windows, consider purchasing an insulation kit. They're inexpensive and you can use a hairdryer or heat gun to apply the material. Another good investment is a caulking gun.
"You're looking for cracks in between door frames and window frames and you're just going to want to fill them in with a nice bead of caulking," added Williams. That's going to keep the cold air from getting into your house and the hot air from leaving."
Door seals and jams are always effective purchases to keep the cold out or if you're on a budget, a towel can also do the trick and, something you might not have thought of is a faucet protector.
