Mitsubishi – PEAD Medium-Static Ducted Indoor Unit – R-454B
See your exact payment → · How financing works
The Mitsubishi Mr. Slim PEAD Series is a horizontal ducted ceiling-concealed indoor unit engineered for medium static pressure duct systems — the right choice when your application requires longer duct runs, multiple supply registers, or a more complex distribution layout. Installed above the finished ceiling and completely hidden from view, the PEAD delivers conditioned air through your existing or new duct network just like a conventional furnace fan coil — but with the efficiency and zoning capability of a Mitsubishi multi-zone heat pump. Available in seven sizes from 9,000 to 36,000 BTU, covering everything from a single bedroom to a large open floor. This page is for the indoor unit and installation only. A compatible outdoor unit must be purchased separately. A controller is also required and is not included. Price includes up to 20 ft of lineset with standard professional installation.
