Abstract
An active fault detection system for a heating, ventilation, and air conditioning system is disclosed. In some embodiments, the system comprises at least one processor; and memory storing instructions, when executed cause the system to: obtain system data related to operation of one or more components of the HVAC system; determine a fault probability based on the system data, the fault probability indicating a probability of a fault in the HVAC system; send a control signal to a component of the HVAC system to modify one or more control parameters of the component responsive to the fault probability being within a fault threshold range, the threshold range having an upper and lower threshold values; update the determined fault probability based on updated system data resulting from modifying the one or more control parameters; and generate a service schedule responsive to the updated fault probability being above the upper threshold value.
