What the new fan energy regulation (FER) means for you.
August 21, 2019 • by Laura Steinhoff
A new fan energy regulation (FER) takes effect July 3, 2019. The regulation states that furnaces can no longer be produced with permanent split capacity (PCM) blower motor. Instead, furnaces must use an electronic controlled motor (ECM). This change largely impacts entry level furnace systems, many high-end furnace systems are already using the ECM motor.
It’s important to note that although the furnace blower motor is connected to the furnace, it is also the blower motor that circulates cooled air from the air conditioner. This means that the motor is in use most of the year.
The change was put into place to reduce energy consumption and carbon pollution. The Department of Energy (DOE) estimates the new motor regulation could reduce the energy usage of the furnace by as much as 46%. For an average home, depending on furnace model, climate and geographic region, it could have an impact of $67.00 per year in energy savings. 
Manufacturers have been preparing for this new regulation, and all units produced after July 3, 2019 will meet the new requirements. However, units produced prior to the regulation taking effect can still be sold until stock is depleted. If you’re looking for a new furnace and want to maximize your energy savings, be sure to pick one that meets the new FER code.
