A methods and system to operate hydraulic fracturing units may include utilizing hydraulic fracturing unit profiles. The system may include hydraulic fracturing units may include various components. The components may include an engine and associated local controller and sensors, a transmission connected to the engine, transmission sensors, and a pump connected to the transmission and powered by the engine via the transmission and associated local controller and sensors. A supervisory controller may control the hydraulic fracturing units. The supervisory controller may be in communication with components of each hydraulic fracturing unit. The supervisory controller may include instructions to, for each hydraulic fracturing units, obtain hydraulic fracturing unit parameters, determine a hydraulic fracturing unit health assessment, and build a hydraulic unit profile including the health assessment and parameters. The supervisory controller may, based on the health assessment, determine the hydraulic fracturing unit's capability to be operated at a maximum power output.
