Trane M5MHWUN09B1N0A Mini Split Outdoor Unit 9000 Btu/h Single Zone Residential Heat Pump

Product Description

The Trane M5MHWUN09B1N0A is a single-zone mini split outdoor condensing unit designed for residential heating and cooling applications. This unit serves as the outdoor half of a ductless split system, housing the compressor and condenser coil to deliver heat exchange between the refrigerant circuit and outdoor air. Rated at approximately 9,000 BTU/h nominal capacity, the M5MHWUN09B1N0A is sized for small spaces such as individual rooms, additions, sunrooms, or any zone where extending existing ductwork is impractical. Installation and commissioning are typically performed by licensed HVAC technicians familiar with ductless system startup procedures.

This outdoor unit is intended for residential single-zone ductless mini split installations. It pairs with a compatible Trane indoor air handler to form a complete heating and cooling system without ductwork. Typical applications include bedrooms, home offices, garage conversions, and supplemental cooling or heating zones in existing homes. The compact outdoor footprint makes it well suited for installations with limited clearance or restricted pad space.
