Air leaks can significantly increase your heating costs. is a fantastic resource for instructions on finding air leaks in your home. Their recommendation includes conducting a visual inspection outside of your home of all exterior corners, outdoor faucets, siding and chimney joints, and areas where the foundation and brick or siding meet.

Set Your Thermostatblanket

Set the thermostat to 68 degrees during frigid weather. This is a comfortable and safe room temperature while awake and can save you up to save you up to 10% on your energy costs. It’s also a good time to dress in layers to stay warm or snuggle under your favorite blanket.


Save Hot Water

Hot water expenses can add up.Set your hot water heater’s thermostat to 120 degrees, or the medium setting. Wrap electric water heaters with water heater blankets, which can be found at home improvement stores.

Keep Doors and Windows Closed

Not only does constant traffic let out warm air, but leaving doors open to empty rooms also puts more pressure on your heater to keep your home at a set temperature. The less you heat up empty rooms in your home, the more efficiently you can heat the spaces you use most. 

Adjust Fans for Winter Use

Fans aren't just for summer. Setting them to rotate clockwise at a low speed during winter can push warm air down from the ceiling to where it's needed.

This will keep cool air from blowing down on you and help the warm air that rises circulate around the room. 

Replace Air Filters replace air filter

Dirty filters make your heating system work harder to heat your home. The harder your system works, the more energy it uses, creating higher bills and less efficiency. Be sure to look at the manufacturer’s instructions and replace accordingly. 



Take Advantage of the Sun
