A controller adjusts a humidity level within an enclosed space. When it is determined to cool the enclosed space, a compressor speed and a compressor run time are determined for a compressor. When it is determined to increase a humidity of the enclosed space, the compressor speed is decreased relative to the compressor speed determined for the compressor, the compressor run time is increased relative to the compressor run time determined for the compressor, a fan is turned on to direct air through an evaporator and into the enclosed space, and a flow of refrigerant is controlled through a coil of the evaporator based on the decreased compressor speed and the increased compressor run time. When it is determined to stop cooling, the compressor is turned off. The fan is turned off when it is determined to end an increase humidity state.
