The Federal Trade Commission's Appliance Labeling Rule requires appliance manufacturers to put these labels on refrigerators, freezers, dishwashers, clothes washers, water heaters, furnaces, boilers, central air conditioners, room air conditioners, heat pumps, and pool heaters. The law requires that the labels specify:

• The capacity of the particular model—for refrigerators, freezers, dishwashers, clothes washers, and water heaters;
  
• The energy efficiency rating and the estimated annual energy consumption of the model—for air conditioners, heat pumps, furnaces, boilers, and pool heaters;
  
• The range of estimated annual energy consumption, or energy efficiency ratings, of comparable appliances
