Staying home during these frigid temperatures is a great way to stay out of the cold, but sometimes that chilly air can seep in.
Frank Berlo of Home Depot said doors and windows can be problem areas for letting cold air in.
"We're talking first about windows. They need caulking," he said. "There might be loose panels and things like that. Just a dollar tube of caulk around the windows is a great savings."
Or if you want to spend more money, Berlo said completely replacing your windows can save up to 15-percent.
Doors can also let out valuable heat.
"Sometimes when you move things, you bang a door," he said. "That puts a dent in the door and air comes through there. So applying weatherstripping can stop that air and save you a lot of dollars on your energy bills."
There is also a tax break for those who want to update their homes.
Consumers who purchase and install certain products such as energy-efficient windows, insulation, doors, roofs and heating and cooling equipment in existing homes can receive a tax credit for up to 30-percent of the cost up to $1,500.
