Does the Goodman R32 air handler come with all necessary refrigerant leak detection safety device equipment or must that be ordered separately?

Yes. When the GLZS4BA3010 condenser is paired with the AMST42CU1300 air handler, the required refrigerant leak detection equipment is already included with the air handler and does not need to be ordered separately. The AMST42CU1300 is designed for R-32 systems and comes with a factory-installed R-32 refrigerant leak detection sensor that is intended to provide the required A2L mitigation functionality.
