The NAECA Act sets standards on minimum energy conservation standards on household appliances & equipment. These standards are designed to reduce energy consumption & lower utility bills in the use of appliances such as Water Heaters, Washer & Dryers, Refrigeration, and other household appliances. The program is maintained by Department of Energy, Office of Energy Efficiency & Renewable Energy.
