1. Check the gutters.
Prevent ice dams by cleaning out your gutters, installing gutter guards (if feasible) and making sure the attic floor is properly insulated. The attic itself should be well-ventilated and about 10 degrees warmer than outside.
2. Protect the pipes.
Protect against frozen pipes by insulating those that could be susceptible to freezing. With severe temperature drops, keep a stream of water running in a few faucets to guard against freezing and bursting.
3. Seal the cracks.
Caulk around holes and openings to help prevent cold air from seeping in. Install weather stripping and seals around openings such as windows, doors, air conditioners and mail chutes.
4.Before using indoor fireplaces, have them inspected and cleaned by a professional.
5. Install an emergency release.
Consider installing an emergency pressure release valve in your plumbing system. This will protect against increased pressure caused by freezing pipes and can prevent them from bursting. It’s also a good idea to learn how to shut the water off and know where your pipes are located.
6. Install a programable Thermostat to save money. Program your thermostat for different times of the day for different temperatures for when you are home and not. 
7. Have heating checked.
Furnaces, boilers and chimneys should be serviced at least once a year to clear any buildup and to keep them running efficiently. Have the furnace filter changed so your furnance operates more efficiently.
8. Test your detectors.
Residential fires are more common in winter, so it is important that all of your smoke detectors work. Check them monthly and replace batteries as needed. You should also consider installing a carbon monoxide detector to avoid inadvertently trapping this toxic gas in your home.
9. Clear the yard.
Keep the trees trimmed and remove dead branches and debris from your yard. Ice, snow and wind can weaken trees and cause branches to fall and potentially damage your home, car or even yourself and others.
10. House the hose.
Remove all attached garden hoses, drain them and store them away. Shut off the valves and insulate the faucet. Outdoor showers should be shut off and drained.
