A portable heating and cooling unit intended to be used within a room or area of a building includes a cabinet supported on a plurality of wheels and a refrigeration circuit at least partially carried within said cabinet. The refrigeration circuit includes a first coil, a compressor, a second coil and a refrigerant reversing valve. In a cooling mode of operation, the first coil acts as an evaporator coil and room air is circulated by a first fan across the evaporator coil and delivered into the room. A second fan circulates room air through the second coil acting as a condenser coil and discharges the thus warmed air away from the room area to be cooled. In a heating mode of operation, the refrigerant reversing valve is activated to change the flow direction of the refrigerant through the circuit such that the first coil now acts as a condenser and the second coil now acts as the evaporator. Room air is drawn by the first fan across the first coil to heat the room air and delivery the room air into the area of the room to be heated. The second fan draws room air through the evaporator coil and discharges the thus cooled air away from the area of the room being cooled. The refrigerant reversing valve is activated by a control which is selectable to choose heating or cooling for the portable unit.
