Allow air circulation. Leave a few inches between the wall and the freezer to allow air circulation behind the unit. Consult your freezer owner manual for the recommended distance to ensure optimum energy savings.

Keep it cool, but not too cold. In addition to turning ice cream into a spoon-bending block of ice, setting your freezer to "max cold" uses more energy and money. Set the temperature at 0 degrees Fahrenheit.

Keep it indoors. Unless you live in a mild climate, keep your freezer indoors, such as in the basement. Extreme temperatures are hard on the compressor and can reduce the life of your freezer.

Check that seal. Make sure the door seals are tight. If not, you could be losing cold air and using more energy.
