Check and improve insulation in your attic, walls, and basements. Good insulation helps retain heat and save on energy bills.
Inspect windows and doors for drafts and seal any gaps with weather stripping or caulk. This prevents cold air from entering and warm air from escaping.
Have your furnace or heating system serviced by a professional to ensure it's operating efficiently and safely. Replace filters and consider installing a programmable thermostat.
Inspect your roof for damaged or missing shingles and repair as necessary to prevent water damage.
Clear leaves and debris from gutters and downspouts to ensure proper drainage and prevent ice dams.
If your ceiling fans have a reverse switch, use it to run the fan's blades in a clockwise direction after you turn on your heat. This pushes warm air down from the ceiling.
Ensure you have snow removal tools and equipment, like shovels and salt, readily available.
Have a plan for dealing with heavy snowfalls, ice storms, and power outages. Know how to safely operate generators or alternative heating sources.
