The U.S. Environmental Protection Agency keeps a complete list of all brands that carry electric furnace models meeting Energy Star efficiency standards. Some brands on the list are Amana, Bryant, Arcoaire, Airquest and Philco. NuTone, Tappan, Westinghouse, Daikin and American Standard also make Energy Star models. Granby, Trane, Goodman, Ruud and Thermal Zone are among other brands with Energy Star electric furnaces on the market. A few other manufacturers, including Rheem, make electric furnaces that carry the label.

The only kinds of electric furnaces that operate efficiently enough to qualify for an Energy Star rating are condenser units. In order to qualify for Energy Star classification, they must have Annual Fuel Utilization Efficiency higher than 89 percent. The AFUE percentage is determined by calculating how much fuel is converted to heat compared to how much is wasted. Some ultra high-efficiency models can get up to 98 percent AFUE. Energy Star rated electric furnaces have very efficient blower motors. Another unique feature these units share is that they have two heat exchangers. Conventional furnaces have only a single heat exchanger.
