Appliances - Refrigerator & Freezer


  • When purchasing a new refrigerator, choose an ENERGY STAR qualified model.
  • Avoid locating your refrigerator in direct sunlight or near equipment that generates heat, such as a range or dishwasher.
  • Leave several inches of space behind and on the sides of your refrigerator so air can circulate around the unit.
  • Every three months, clean the condenser coils located underneath or in the back of your refrigerator or freezer.
  • Be sure your refrigerator stands level so the door seals evenly and tightly.
  • Check the door gaskets for air leaks by shutting a piece of paper in the door. If you can slide the paper out without resistance, your refrigerator may be leaking cold air.
  • Let hot foods cool before placing them in the refrigerator. Cooked meats, however, should be refrigerated immediately.
  • Liquids should be covered. Moisture is drawn from uncovered liquids, forcing your refrigerator’s “no-frost” unit to work harder.
  • If your refrigerator has steel racks, don’t cover them with paper or foil. Doing so will reduce the flow of cold air.
  • Don’t overload your refrigerator. Cool air should be allowed to circulate around each container.
  • Don’t over-cool your refrigerator. The recommended temperature is 38° F to 40° F. Keep your refrigerator just low enough to chill milk. For the freezer section, 5° F is recommended, low enough to keep ice cream hard. (You may need to adjust the setting during the summer months.) Use a thermometer to check settings.
  • Try to cut down on the number of times you open the refrigerator door. Plan ahead and take out everything you'll need at one time.
  • If you’re going away for a long period, use up perishable foods, turn your refrigerator off and leave the door open.
  • Consider removing your second refrigerator or freezer. If you must use a second refrigerator for part of the year, unplug it for the rest of the year and leave the door open.
  • Replace of any refrigerator or freezer in your home that’s more than ten (10) years old and you may save as much as $100 annually in energy costs, when you replace it with an ENERGY STAR qualified model.
  • Remove frost when it is 1/4 inch thick. Heavy frost buildup decreases efficiency and uses more electricity to maintain the same temperature.
  • Consider high-efficiency appliances. Leading refrigerator models use 7% to 13% less energy. High-efficiency dishwashers use 25% less energy than conventional models, and high efficiency clothes dryers can save up to 30% in energy use over standard models.
  • Check door seals on the refrigerator. A broken seal is the same as leaving the door open. Replace the seal if it is torn or partially missing. To test it, close the door on a single sheet of paper and try to pull it out. If it slides out easily, it needs to be replaced to prevent cold air from leaking out, or consider buying a new unit.
