Zusammenfassung:	The disclosure relates to a method of monitoring a refrigerant leak. The method includes monitoring, by a first controller (120a), operation of a first HVAC system (100a) for conditioning air within a first level of a residence, monitoring, by a second controller (120b), operation of a second HVAC system (100b) for conditioning air within a second level of the residence and determining, using a plurality of leak detectors (127a, 127b), whether refrigerant within the first HVAC system (100a) is leaking. Responsive to a positive determination in the determining step, receiving, by the first controller (120a), a refrigerant leak warning signal, forwarding, by the first controller (120a) to the second controller (120b), the refrigerant leak warning signal. Responsive to receiving the refrigerant leak warning signal from the first controller (120b), activating, by the second controller (120b), a variable-speed circulation fan (102b) of the second HVAC system (100b).
