1. A method comprising:

  • monitoring a pressure of compressed air within a reservoir of a compressor, the reservoir configured to store compressed air to be provided to at least one pneumatic device, and the compressor having a first stage to compress air to a first pressure level and having a second stage to pressurize air from the first stage to a second pressure level which is greater than the first pressure level;

    actuating a piston within a cylinder of the second stage of the compressor; and

    detecting a leak condition of an exhaust valve of the cylinder based on an analysis of a frequency domain of the monitored pressure of the compressed air within the reservoir during a time period in which the piston is actuated;

    wherein detecting a leak condition of the exhaust valve of the cylinder further comprises correlating the monitored pressure of the compressed air within the reservoir with an indication of a position of the piston in the cylinder.
