The EnergyGuide provides consumers in the United States information about the energy consumption, efficiency, and operating costs of appliances and consumer products. Clothes washers, dishwashers, refrigerators, freezers, televisions, water heaters, window air conditioners, mini split air conditioners, central air conditioners, furnaces, boilers, heat pumps, and other electronic appliances are all required to have EnergyGuide labels. The label must show the model number, the size, key features, and display largely a graph showing the annual operating cost in range with similar models, and the estimated yearly energy cost.
