Webinar: Furnace Fan Energy Rating

Furnace fans are among the largest users of electricity in a typical household, consuming nearly 10% of an average household’s electricity use, or about 1000 kWh of electricity per year. In 2014, the US DOE established the first national efficiency standard for furnace fans. The new standard, which will take effect on July 3 2019, specifies a maximum Fan Energy Rating (FER) that varies based on the airflow provided by the furnace fan. This webinar will explore the new standard as well as details of the testing used to qualify furnace fans.
