Now you can cool a room without any ductwork or special wiring--and move the unit from room to room as needed! The PS-91B is ideal for situations where a window isn't available or the existing window can't handle a room AC unit. Rated at 9,000 BTU, the PS-91B can be used to supplement the central cooling system, or to save energy by conditioning only the room being used. The unit moves easily from one space to another thanks to casters and built-in handles. A condensate management system eliminates buckets that have to be emptied.  The PS-91B comes complete with everything needed for operation and installation, including sliding adapters that fit a variety of window sizes (double-hung and slider) and patio doors to make installation fast and easy. The unit comes with a 48" long hose, for both hot air exhaust and air intake.
