Air conditions units

We have serious problems with the air condition units on different hotels. Are the Air conditioning units on board the different ships able to control temperature and airflow? Are they silent?

Yes, you can control the temperature. If you experience trouble call the front desk and they will help you immediately. Unfortunately you cannot control the airflow. Don't forget that there are cabins with no balcony so it is not safe if the airflow in those cabins is not constant.
