Designed for in-ceiling, below-the-floor or vertically in the wall applications, the Preferred™ Series 40MBDQ Ducted indoor unit is the perfect fit. It senses the temperature at your handheld remote and delivers the right amount of airflow with three available fan speeds. And it’s quiet, too, the perfect complement to a single or multi-zone ductless comfort system. This unit is also available in a high-static model compatible with our 38MBR single zone heat pump.
