Refrigerators and freezers use electricity to transfer heat from articles placed inside them to their exterior, their efficiency is inversely proportional to the inside to outside temperature difference, they work better if it's cold externally. When doors or lids are open cool air escapes increasing their operating costs, how to measure home temperatures.

Over the years refrigerators and freezers have been enhanced to transfer heat more efficiently, insulation levels have also been increased reducing operating costs.

What can I do to reduce refrigerator and freezer energy costs?
  •   If possible put your refrigerator/freezer in a cool room, they will operate more efficiently.
  •   Reduce the number of trips you make to the refrigerator/freezer.
  •   Never leave the refrigerator/freezer door or lid open for any longer than necessary.
  •   Keep you refrigerator/freezer full, especially front opening units, there will be less cold air to escape when opened. Fill empty spaces with, cardboard boxes, empty containers or bubble wrap.
  •   Replace old refrigerators with new and replace old freezers with new, these are far better insulated and operate more efficiently.
  •   Remove accumulated ice, never let more than ¼ inch of ice accumulate in your refrigerator/freezer, it reduces the units efficiency.
