    Abstract: A heat exchanger system includes a heat exchanger coil, a base of a foam structure including a clamp with a first arm and a second arm, where the first arm and the second arm are configured to exert a clamping force against the heat exchanger coil, and a vertical member of the foam substructure coupled to the base and abutting a cover of the heat exchanger system, where the base and the vertical member are configured to block air flowing through the heat exchanger from flowing into a void between the heat exchanger coil and the cover.

    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.
