Abstract: A heating, ventilation, and air conditioning (HVAC) system includes multiple circuit components that enable determining that a refrigerant leak is present in the HVAC system based on a signal. The circuit components then send a first set of instructions to a first set of control systems associated with one or more fans in response to the refrigerant leak being present.

The system then determines that the refrigerant leak signal is no longer present, and initiates a counter to detect when a period of time has passed in response to determining that the refrigerant leak signal is no longer present. The system then sends a second set of instructions to the first control system to cause the fans to return to base operating conditions in response to the counter indicating the period of time has passed.
