CLEVELAND -- As the temperature turns colder people start looking for ways to stay warm.

The "As Seen on TV" product the Twin Draft Guard claims to be the barrier we need, keeping winter out and reducing utility bills up to 30 percent. But does it really do that?

NewsChannel5's Joy Benedict called on Home Energy M.D., Gary Canter who spends his days checking the energy efficiency of homes, to find out if the product lives up to its claims. He uses tarps and blowers to seal off and depressurize homes to check for leaks. Then he uses a thermal camera to check the temperature around certain areas of the house.

5 On Your Side put Canter to work, to see if the Twin Draft Guard really does keep the cold air out. He fit the product around some windows but the Twin Draft Guards weren't long enough and the window wouldn't close all the way. That meant the windows couldn't lock, creating a safety hazard.

Did the product keep the air out? Canter said he could still see air flow, but the corner near the windows did rise in temperature by three degrees.

There are things you can do in order to keep leaks to a minimum in your house. A home energy examiner takes a look at your whole house and diagnoses the areas where making changes would improve your energy efficiency, comfort and overall home performance.

A home energy physical takes up to three hours depending on the size of your home. You do need to be home during that time in case there any questions or concerns arise. A home energy M.D. like Canter would start by reviewing your energy bills and then perform a complete assessment of your home from top to bottom using state-of-the art diagnostic tools.
