A controller is configured to operate a heating, ventilation, and air conditioning (HVAC) system based on a plurality of concentration measurements received from a refrigerant detection sensor. The controller is configured to receive the plurality of concentration measurements from the refrigerant detection sensor disposed upstream of an evaporator coil. The controller is further configured to determine if a concentration of a refrigerant in a volume exceeds a stored threshold value based at least in part on the received plurality of concentration measurements. In response to determining that the concentration of refrigerant in the volume does exceed the stored threshold value, the controller is configured to operate the HVAC system in a second mode of operation, wherein the second mode of operation includes turning off a compressor and actuating a blower disposed downstream of the evaporator coil to discharge an airflow.
