A maintenance method for a heating, ventilation or air conditioning system, comprising a system control mainboard and a motor having digital signal processing capability. A data backup area is provided in a storage device in the system control mainboard. When the system control mainboard experiences a fault, a replacement new system control mainboard is connected to a compiler having a Bluetooth interface and communicates with a mobile phone via the compiler having the Bluetooth interface. The mobile phone is connected to a cloud server via a mobile communication network. The cloud server stores as backups operating parameters of various system control mainboards. Relevant information of the old system control mainboard that experienced the fault is inputted utilizing the mobile phone and uploaded to the cloud server. The cloud server searches for relevant operating parameters corresponding to the old system control mainboard that experienced the fault and re-writes into the storage device of the new system control mainboard via the mobile phone and the compiler having the Bluetooth interface to serve as the operating parameters of the new system control mainboard.
