Brushless DC Motors

Most small motors, commonly found in air handlers, air conditioners and refrigeration applications, are Permanent Split Capacitor (PSC) induction type. PSC motor efficiency, when operating at full load, ranges from 45% to 65%. Lightly loaded PSC motors are significantly less efficient and most PSC motors are over-sized in order to allow for flexibility in application.

Both your heating costs as well as the comfort level inside your home can benefit by upgrading from an outmoded PSC unit to an ECM furnace blower motor. That can decrease energy usage by as much as 75%
