Preparing for cold temperatures can fall into two categories -- routine maintenance and home improvement.

1. The time is now to make sure that your furnace is ready for a heavy winter workload. November is a good time to have a heating and cooling company clean and inspect your furnace. 

2. Make sure to start out the heating season with a clean furnace filter. Check it monthly during the winter months to see if the filter needs to be cleaned or replaced. As a reminder, check your filter when you receive your electric bill. Heating systems need clean filters to operate efficiently. 

3. Keep the heat in and the cold air out by identifying and sealing air leaks. Windows and exterior doors can be common culprits, but often the biggest air leaks exist in attics, crawl spaces, and basements. Check out the Energy Star Air Sealing page to learn more about how air sealing can help you improve your home and maximize your energy dollar.

4. Check your attic insulation levels. You should have at least 12 inches of cellulose or 18 inches of blown fiberglass insulation. If you can see the ceiling joists, you need more insulation.
