Some new homes are designed especially to keep the cold air out. If your house isn’t, you may be surprised at how easy it is to make it more energy efficient.

"If you walk around this you can't feel any cold air at all, there isn't a draft in the house whatsoever." Scott Davis just moved back from Florida and found a house that he says will save him money. "Probably save between $300 and $800 a year."

That's the expected payoff with the Energy Star rating. The builder, Hearthstone Homes, uses a plan designed to be 20 to 30 percent more energy efficient.

"The duct work is a lot tighter seal than in normal constructed homes,” says OPPD’s Gary Ruliffson. “Some of us don't live in an energy efficient home and the big thing is to keep the air from coming in and you have a product there."

"Air leakage can cause 30 to 40 percent of your cost so what you want to do is find those locations through the utility lines coming into the home and hold the adapter down. Believe it or not, air does move underground. It will come under those gaps in the wall so any exterior gap that you see you want to seal that up to reduce that air leakage."

Another possible source of cold air in your home are wall plugs. You can easily seal those as well.

“What you do is you take your cover off and you take your two foam pads and take your cover and screw it back in place and these are very inexpensive and ideally, again inside walls and the outside walls, these are good products to reduce that air leakage," says Ruliffson.

If you don't have an energy efficient home like Davis, you can do some simple things around your home to save money. Visit energystar.gov and oppd.com.
