Clicking noise during operation
A clicking sound can be heard either
when the unit starts or stops due to
movement of the reversing valve.
Creaking sound during operation.
The plastic parts of the indoor unit
make sounds due to shrinkage
and expansion during sudden
temperature shifts.

Switching of the flow of refrigerant
through the air conditioner produces
water flowing noise.
