There is sound of running
water during the running
of air conditioner.
Sometimes the "hissing" sound of running water
can be heard. This is the sound of the flow of the
refrigerant, not a malfunction.
A slight "click" sound is
heard at the of start-up or
shut-down.
Due to temperature changes, panel and other parts
will swell, causing the sound of friction. This is normal,

runs for some time, the indoor temperature and
humidity will be reduced and the mist will disappear.
