If the difference between the indoor temperature and the target temperature is big, then during initial operation, as the motor rotation count is set to very high,
thus high fine frequency noises can be heard.
Once the indoor temperature reaches the target temperature, noises from the outdoor unit including high frequency noises will be reduced.
Causes and Symptoms
- During initial operation, or when you lower the target temperature, intermittent high frequency noises are heard for some time.

Try this
Increase the target temperature for use.
Depending on the difference between the indoor temperature and the target temperature, the number of outdoor motor rotations gets high.
Set it to less than 3℃.
If you set the target temperature too low, then the power consumption will be high and it is likely for you to get an air-conditioningitis due to a high temperature difference.
※ High frequency noises from the air conditioner can be temporary or intermittent but if it is consistent enough to cause discomforts in use,
then it requires inspection by a professional service manager.
