from the air conditioner in cooling or drying operation.
• The refrigerant flows in the air conditioner even if the
air conditioner is not working when the indoor units in
other rooms are in operation.
Blowing sound
• This sound is generated when the flow of the
refrigerant in the air conditioner is switching.
Ticking sound
• This sound is generated when the size of the
air conditioner slightly expands or shrinks as a result
of temperature changes.
Clicking sound during operation or idle time
• This sound is generated when the refrigerant control
valves or the electrical parts operate.

• This sound is heard from the inside of the air
conditioner when the exhaust fan is activated while
the room doors are closed. Open the window or turn
