1. A method comprising:

  • monitoring a pressure of compressed air within a reservoir that is fluidly connected to a compressor;

    actuating an unloader valve of the compressor by cycling the unloader valve between an open position and a closed position of the unloader valve during a time period;

    correlating the monitored pressure of the compressed air within the reservoir during the time period with the open position of the unloader valve and the closed position of the unloader valve;

    detecting a leak condition during the time period by determining a difference between a rate of change of the monitored pressure of the compressed air within the reservoir while the unloader valve is in the open position and a rate of change of the monitored pressure while the unloader valve is in the closed position; and

    automatically generating a signal in response to detecting the leak condition to one or more of notify personnel of the leak condition or control the compressor based on the leak condition that is detected.
