Abstract

The present disclosure relates to a method (100) for prediction of a maintenance need of an air handling unit, AHU, comprising at least one power component. The method obtains energy consumption, EC, profiles for the AHU as a whole as well as the at least one power component and compares the profiles with current EC behavior in order predict the maintenance need. The present disclosure also relates to corresponding air handling units, systems and computer programs.
