What is the recommended temperature range for a residential freezer?

The recommended temperature range for a residential freezer is 0 to 5°F. This temperature range is ideal because it effectively prevents the growth of bacteria and other pathogens that can spoil food. Food stored at this temperature will remain frozen, ensuring its quality and safety for extended periods. Maintaining the freezer at this temperature also helps to preserve the nutritional value and texture of the food items stored within it.

In addition to food safety, this temperature range balances energy efficiency. Freezers operating within this range generally consume less energy while maintaining optimal conditions for food preservation. Lower temperatures may not be necessary for all home freezing needs and could lead to increased energy consumption without additional benefits. Thus, keeping the freezer at 0 to 5°F strikes a practical balance between safety, food preservation, and energy efficiency.
