Featuring SmartHinge™ louver design, the XC25 provides quick, easy access to interior components from all sides, so the unit can be serviced in minimal time. Exclusive SilentComfort™ technology makes the XC25 very quiet. A composite fan design with variable-speed operation and an insulated compressor compartment also helps reduce sound levels.
