Seal off your windows with a window insulation kit. The sealing plastic that goes over the window is barely visible when put on.
Change out your furnace filters. It’s important to clean or switch your furnace filters because dirty filters block the flow of air.
Run your fans in reverse. Many homes have a switch that can reverse the rotation of a fan. This pushes all the wasted heat near your ceiling down to the lower levels of a room.
Drain hoses and other outdoor water sources. Make sure your hoses are stored away during the winter and outside water spigots are turned off.
Lower the drafts in your home. You can buy or make a draft snake to put on the floor by doors or on windowsills. These can be made by rolling up a towel or, if you want to be creative, get some fun fabric and stuffing and make one yourself!
Watch your thermostat. You can save a lot of money by lowering the temperature on your thermostat before you leave your home.
Caulk corners and weak points in your home. Corners, the space around bathtubs or showers, and visible pipes and wires can let cold air in. Get some caulk and seal these up!
Insulate your home’s pipes! By doing this, you pay less for hot water and it helps to keep your pipes from freezing. Pipe foam and insulation can be found at many hardware stores.
Close off rooms that aren’t used often and shut the vents. This will direct the heat of your home into the parts that are busier.
Replace old or weak windows. Windows are one of the main reasons that cold air comes into your home. If a window is broken or not sealing well, replace it to keep heat in.
