Freezers are available in various sizes and stylish designs for homes, farmhouses, grocery stores, and other commercial uses. Opt for upright freezers when working with limited food storage space because of their small footprint. Electric freezers come with capabilities such as auto defrosting to increase energy efficiency. Some can keep food frozen during blackouts for as long as 24 hours. Stock up on important staples with chest freezers. There are horizontal and upright styles with multiple shelves or removable wire baskets for added ease of use.
