Lowering Your Freezer Energy Usage

Here are some good tips to save on using your freezer from the Department of Energy:

• Locate freezers away from heat sources and direct sunlight.
• Allow at least 1 inch space on each side of freezer to allow good air circulation.
• Freezers can be installed in an attached garage or basement. However, don't put a freezer in a space that frequently goes below 45°F, as the refrigerant will not work properly.

• Freezer temperature should be kept at 0°F.
• Regularly defrost manual defrost freezers; frost build-up increases the amount of energy needed to keep the motor running. Don't allow frost to build up more than 1/4 inch.
• Make sure the freezer door closes tightly. Check the door seals and gaskets periodically for air leakage. Lubricate the gaskets with petroleum jelly to keep them from cracking or drying out.
• Avoid putting hot foods directly in the freezer. Let them cool in the room first.
• A full freezer will perform better than a nearly empty freezer.
• Mark items in the freezer for quick identification so that you don't have to keep the door open longer than necessary.
