1. A refrigerant leak detection system for a climate control system, the system comprising:
an air unit comprising a housing and a heat exchanger including a conduit, the conduit including one or more joints and configured to carry a refrigerant of the climate control system, and a space located within the housing and outside the conduit;
a transmitter located within the space and adjacent the heat exchanger, the transmitter configured to emit an acoustic wave within the space and direct the acoustic wave to travel adjacent to at least one joint of the conduit;
a receiver located within the space and adjacent the heat exchanger, the receiver configured to detect the acoustic wave traveling within the space; and
a controller coupled to the transmitter and the receiver, wherein the controller is configured to:
determine a time of flight for the acoustic wave between the transmitter and the receiver; and
determine whether the refrigerant is present in the space based on the time of flight.
