Make the fall your prep time for winter.
September is a great month for preparing for winter. It's not too hot or cold to check some areas of the house that need attention.
Check the roof for any loose or missing shingles. This should be repaired before winter hits.
Ducts should be checked. Over time the seal can come loose. This can let heat into the attic causing snow to melt and refreeze causing ice dams on your roof.
The end of fall is a great time to drain your water heater. This should be done once a year. Do it now before you find out your only have really cold water in your house.
If you have a chimney, make sure you sweep it (or have it professionally swept) before lighting any fires for the season. Removing the excess soot, as well as the birds and animals that made their homes in chimneys throughout the year, will help prevent fires and smoke damage. Also, examine the damper to make sure it’s still looking good. If it’s bent or warped, warm air will be able to escape through the chimney.
If you have ceiling fans, now is the time to reverse them. Putting them in reverse will help blow down warm air that would otherwise be stuck near the ceiling, which will likely mean you can turn your heat down a degree or two.
Enjoy the fall weather but also make it a time to check your home for the winter.
