Definition of conditioning - "The process of training or accustoming something to behave in a certain way or to accept certain circumstances."
Air is very spirited and will always do what it wants. For thousands of years people have tried to "condition” (train or “break”) air. By itself, air is rather thin, meaning it doesn’t do much. But when air gets together with its friends, it tends to get a bit “blustery” (wind). If one thinks that training/breaking air is hard, good luck with wind.
Air can be moody. On occasions, air’s mood can be stable and nice, other times it can get very violent and will start throwing things around (particularly after it’s been “dry” for awhile and then goes out “drinking” with its friends). When (de)pressed, air tends to get hot (angry), but when it’s happy it can be cold and aloof. Therefore, it is ill-advised to try to condition air. Air is best when left alone
