1. A heating, ventilation, and air conditioning (HVAC) system, comprising:
a closed loop refrigeration circuit including a heat exchanger assembly;
a detection assembly operable to detect refrigerant from the closed loop refrigeration circuit mixed with air;
a mitigation device operable to monitor at least one parameter associated with operation of the detection assembly to detect if frost is present at the detection assembly; and
a controller operable to both the detection assembly and the mitigation device, the controller being operable to determine if an alarm generated by the detection assembly is a false alarm in response to the at least one parameter monitored by the mitigation device.
