Drain and store your hoses
When the temperature drops too far, you may be in danger of experiencing frozen water in your water hoses. If this happens, you may end up having to either patch the hose or buy a new one when the spring rolls back around. Before temperatures drop too far, detach your hoses from any outdoor faucets, drain the water out of them, then store them someplace safe until you need them again.
Clean your gutters
Suppose the water cannot make its way down the gutters. In that case, it can instead collect on your roof, freezing and causing damage to your roof, up to and including leaks — which you definitely do not want to discover when the snow starts to melt again in the spring or during your first April shower of the year. All of this can be prevented with one conscientious gutter-cleaning after most leaves are gone, so do not neglect it, even if it might seem tedious and annoying.
Get an energy audit
Before you start winterizing your house, it is paramount to know that the more drafty or leak-prone your house happens to be, the more work you have to do to get it ready for the coldest season of the year. An energy audit is often offered for free by your utility company. It involves a visit by a licensed professional who will comb over your doors, windows, heating and cooling systems, and many other parts of your house.
Reverse your fans
If you ever took physics in school, you may recall learning about the principles of thermodynamics — hot air tends to rise while cold air tends to sink. Not only is this true, but your ceiling fans operate according to these principles — when you look up at your fans in the summertime, they should be running in a counter-clockwise direction in order to redistribute the cool and warm air in the room.
Flush your water heater
To avoid any inefficiencies as a result of sedimentation, an easy fix is to flush your heater — which involves pouring out the water that’s currently inside it, including any sediment that’s made it’s home inside your water heater. It’s inexpensive and relatively quick, and it’s something that most homeowners should consider doing as part of their winterizing package.
