If you do not want this function, you can turn the indoor unit off.The air outlet on the indoor unit is discharging mist.The cooled air from the appliance makes mist.When the room temperature decreases, this phenomenon will disappear.Water leaks from the outdoor unit.In the heating operations, condensed water drops from the heat exchanger.This requires that a drain hose should be installed under the base pan. Contact the installer.There is noise or vibration.A clicking sound can be heard when the appliance starts or stops due to movement of the reversing valve.Creaking sound: The plastic parts of the indoor unit creak when they shrink or expand due to sudden temperature changes.Flowing or blowing sound: This is the flow of refrigerant through the appliance.Noise is normal during or after operation.

Please wait until the appliance has generated enough warm air to blow through the indoor unit.The outdoor unit is in Defrosting mode.In Heating mode, ice and frost is built up on the coils when the outside temperature falls. The Defrosting mode reduces a layer of frost on the coil, and it should finish in approximately 15 minutes.Outside temperature is too low.The heating effect may not be sufficient.
