 Please Be advised of the new
Fan Energy Rating or (FER)
The Department of Energy’s or (DoE) Fan Energy Rating (FER) regulation will take effect on July 3, 2019 for all residential furnaces. FER was approved by DoE in 2014 and is the first national efficiency standard for furnace blower fans. FER specifies a maximum fan energy rating, which varies based on the heating stages of a furnace and the motor watt consumption at various airflow operating points for heating, cooling and continuous fan. This new standard will require a 46% watt reduction over a typical permanent split capacitor (PSC) motor furnace. Due to this reduction in watt consumption of furnaces, the Standard PSC furnaces will become obsolete as of July 3, 2019 and discrete tapped electronically commutated motor or (ECM) motor furnaces will be the new product. The July 3, 2019 effectivity date is based on date of manufacture and there is no restriction on when the furnace may be installed.
