Freezers run most efficiently when filled tightly, so resist the temptation to purchase the biggest unit you can afford. Thanks to newer insulation materials, smaller units offer more capacity than freezers only a few years old.
If you're purchasing a manual-defrost freezer, a drain will make defrosting much easier.
- Experts prefer adjustable temperature control. Nearly all full-size freezers have a temperature-control knob.
- A lock is an important safety feature for homes with children. Most freezers come with a lock and a couple of keys.
- Finding food in a jam-packed freezer isn't easy, so look for an interior light.
- A power "on" light is useful for making sure the freezer's power hasn't gone out.
In the event of a power outage, experts say that food will remain frozen for at least 48 hours as long as the door is kept closed. So if you do have a power failure, resist the temptation to open the door to check on the food. There is some concern that freezers, especially self-defrosting models, can dry out food. But experts state that if food is tightly wrapped (to keep moisture in) this should not be a problem.
