The invention provides a plug and play remote control air conditioner system and method. The remote control air conditioner system and method can be applied to air conditioners of various models, on the basis of the distributed application technology, all controllers are relatively independent, and therefore all the controllers can be subjected to batch processing, each single controller can also be controlled and the changes of all the controllers do not interplay. A server is an application program which is easy to load and unload, and the server can be conveniently installed on different computers and mobile phones and can be simultaneously installed on the different computers and mobile phones to control all the controllers. Meanwhile, in order to ensure that each controller can only be controlled by users, security codes and characteristic codes of the controllers are set to conduct relative verification, and thus the safety is ensured.
