Select Lennox cooling products are specifically designed to deal with harsh weather conditions and debris buildup. The outdoor units of the XP21 and XP17 heat pumps and the XC21 and XC17 air conditioners all include the exclusive SilentComfort™ fan motor, which senses the buildup of frost, ice or dirt on any part of the fan assembly. If such buildup occurs, the motor automatically compensates by operating at a higher starting torque and alternating the rotational direction of the fan to allow its specially designed composite fan blades to break up the debris. The fan motor then resumes normal operation, keeping the air conditioner or heat pump running at peak efficiency.
