The goal of Energy Star is to help end users identify products that are significantly more energy efficient than others in the marketplace. For those who want to save even more money, Energy Star has issued its Most Efficient Furnaces of 2013 list, which features equipment that achieves efficiencies of 97 percent AFUE or higher. In addition, furnaces on this list must include two-way communications with the system controller, automated configuration, a thermostat or other control device with a user interface that can be located in the conditioned space, and fault code transmission to the indoor controller.
Homeowners choosing to purchase these highly efficient furnaces will reap the benefits of lower energy bills, while contractors will appreciate the many features that make them easier to install and service. Below, you’ll find a sampling of Energy Star’s Most Efficient furnaces. The entire list can be found at www.energystar.gov.
