1. Check your windows and doors for drafts and gaps.
2. Examine the roof for potential damage, including cracks, warping, loose shingles, etc.

4. Test your heater, furnace, and other heating systems to make sure they are in proper working condition.
5. Change the air filter on your furnace to ensure better air circulation.
6. Test your smoke and carbon monoxide detectors and replace the batteries in all of them.
7. Check your pipes for any breaks and make sure they have proper insulation.
