Why would a hotel-style heater blow cold and hot air at the same time and other times not work at all?
If the unit is a heat pump, and the fan switch is set to ON, the unit compressor will cycle to maintain room temperature. Thus, it would blow hot or cold, depending on if the compressor was on, and the thermostat was calling for heat. Turn the fan switch to off, and let the thermostat bring the fan on. Not working part, no comment on that.
