Abstract
Examples of the present disclosure relate to climate control systems and air handler units with improved leak detection, along with method for installing these systems. In some examples, the climate control system comprises a heat exchanger configured to exchange thermal energy between a conditioned airflow and a refrigerant fluid; a drain pan arranged to collect condensate produced at the heat exchanger, the drain pan including one or more drains configured to route condensate out of the drain pan; a refrigerant leak sensor coupled to the drain pan and positioned above the one or more drains and configured to detect a refrigerant leak; and control circuitry operably coupled to the refrigerant leak sensor, the control circuitry configured to: receive a signal from the refrigerant leak sensor indicative of refrigerant located outside the closed circuit associated with the heat exchanger, and determine a refrigerant leak has occurred based on the signal.
