Permanent split capacitor (PSC) condenser fan AC motors have a high starting torque and energy efficient performance with a cooler operating temperature. They help cool the condenser by drawing outside air through the coil and expelling it out of the top of the unit. This brings cool air into your home.,Permanent split capacitor (PSC) condenser fan AC motors have a high starting torque and energy efficient performance with a cooler operating temperature.
