refrigerators and freezers energy savings

In most homes, the refrigerator is the most energy-consumer appliance.

Below, we list some tips for getting energy savings from your refrigerator and freezer.

Small units, ice, top-mounted

Prefer qualified smaller units without ice and water dispensers. Also prefer compact and top-mounted models. They are much more efficient. See: Dishwasher efficiency and Dishwasher Rating.

Refrigerator Door Seals

Check the tightness of your refrigerator or freezer door seals. To test them, put a flashlight inside the refrigerator, directing the light toward the section of the door seal you want to inspect. Then, close the door and inspect for light (test in a darkened room). You may also use a piece of paper or a money bill: the refrigerator closed door should hold the bill/paper.

Thermostat

Do not set the refrigerator thermostat too high. To get energy savings, adjust the thermostats inside the refrigerator. Use 37°F - 40°F (3ºC) for the refrigerator and 0°F - 5°F (-17º -15º) for the freezer.

Keep refrigerators from working too hard

Refrigerators shouldn’d be located under sunlight or next and near to appliances like stoves or dishwashers. It will also cause them to work harder. Do not put hot foods in the refrigerator. Let them cool first.

Air circulation and fridge defrost

Air should circulate freely around the refrigerator.

If your fridge or freezer uses manual defrost (modern ones have automatic defrost), pay attention to it and to its periodicity. Defrosting should be done more often in hot climates and non-conditioned homes.
