Abstract
A control system for a heating, ventilation, and/or air conditioning (HVAC) system includes a sensor configured to detect a concentration of refrigerant in air. The control system also includes a controller configured to receive feedback from the sensor indicative of the concentration of refrigerant in air, determine that the concentration of refrigerant in air is less than a threshold value, and determine that the HVAC system is in an operating mode. The controller is configured to operate a blower of the HVAC system for a predetermined time period based on the determinations that the concentration of refrigerant in air is less than the threshold value and that the HVAC system is in the operating mode.
