Americans often send their energy and hard-earned money right out of the window. Badly insulated windows can make cooling and heating systems more difficult to maintain comfort. Homeowners can feel uneasy and waste hundreds of money.

Consumer Reports claims that replacing old windows can reduce heating and cooling costs by up to 25%. However, replacing all windows in a house can cost homeowners between $7,000 and $20,000; however, energy-efficient windows may take 20 years to pay off. Old windows that are not repairable with weather stripping and caulking should be replaced. However, homeowners who have windows that still work should consider upgrading.

Here are some tips for keeping your house warm this winter.

Weatherstrip all windows and doors. You will save money on heating by making sure your doors and windows are sealed. Weatherstripping is required if you find cold drafts around doors and windows. If you are unsure, ask someone to stand on the other side and then blow your hair with a hand dryer at either the door or window.

You should check for drafts by making sure the door or window fits in the frame. If the door or windows are crooked, the weather stripping will not fit on every side. It may also make it impossible to close the door. You can purchase a weatherstripping set if your window fits, but is still drafty. There are many types of weatherstripping, so it is worth asking a professional.

Insulating blinds can be added. Homeowners can control the light they use and save money by using energy-efficient blinds. Comfortex Window Fashions, one company(*)(
