It is always good to keep your refrigerator and freezer full so they don’t have to work as hard to stay cold. And if you are getting ready to leave town for awhile and the fridge is almost empty, it is best to fill voids in the fridge or freezer with containers of water or other items to take up space.

The following are more refrigerator and freezer energy saving tips from Mass Save:

  • Think about what you’re going to get from the refrigerator before you open the door.
  • Set your refrigerator to 35 to 38 degrees Fahrenheit and your freezer at 0 degrees Fahrenheit. Anything above that is a waste of energy.
  • Position your refrigerator away from a heat source, such as an oven, dishwasher, or direct sunlight from a window.
  • Leave a few inches between the wall and the back of the refrigerator for air circulation.
  • Make sure the seals around the door are airtight. If not, replace them.
  • Make sure condenser coils are cleaned and air can circulate freely. Read the user manual to learn how to safely clean coils. Coil cleaning brushes can be purchased at most hardware stores.
  • Consider replacing and recycling older-model working refrigerators, especially those made before 2000. Older model refrigerators often use more than four times the energy of newer models.
  • If you’re purchasing a new refrigerator, one with a top-mounted freezer is generally the most efficient. And choose the smallest one that fits your needs. In general, the larger the refrigerator, the greater the energy consumption.
