Each cubic foot of freezer space can hold about 35 pounds of food. In addition, some families will require additional freezer space if they cook and freeze foods for future use. If the freezer is a replacement, decide if the size of the previous appliance was large enough to meet the family's food storage needs. For the most efficient use of energy dollars, keep the freezer at least two thirds full. The most popular size purchased is 15 cubic feet.
Some upright freezers have the no-frost system.
Chest and compact freezers are manually defrosted. The manual defrost freezers are better at holding the temperature at one level for large amounts of food. Front drains are available on some models, which provide easy connection to hoses to release water during defrosting. Energy labels When shopping, read the energy guide labels on the freezers to find the most energy efficient appliance that best suits the needs of the family. Look for the lowest annual operating cost among freezers of similar size and defrost systems.
