Home winterizing tips

Some other low-cost home winterizing tips:
Use a programmable thermostat. When installed and used correctly, you may be able to save $180 each year.
Get a tune-up for your furnace and change your furnace filter monthly. Clean filters create better air flow, while dirty filters can hike energy usage.
Reduce drafts by sealing air leaks and add insulation to keep precious heat from escaping. The EPA estimates that homeowners can typically save up to 20 percent of heating and cooling costs (or up to 10 percent of total energy costs) by air sealing their homes and adding insulation in attics, floors over crawl spaces, and accessible basement rim joists.
Get a window insulation kit from the hardware store to keep drafts at bay.
