Abstract
Systems and methods are disclosed that involve detecting a flammable refrigerant associated with a heating, ventilating, and air conditioning (HVAC) system. In one instance a damper covers an access port allowing a single sensor to monitor at least two separate spaces. In another instance, a multi-probe sensor allows a single sensor to monitor at least two separate spaces. Other systems and methods are presented.
