After servicing a refrigerant leak, what must be verified before reconnecting the system?

Verifying that no further leaks are present after servicing a refrigerant leak is crucial for several reasons. First and foremost, if a system still has leaks, it will be unable to maintain the necessary refrigerant levels, resulting in reduced efficiency and potential system failure. Refrigerants also have environmental implications, so ensuring that there are no leaks helps comply with regulations regarding refrigerant emissions.

After repair work has been completed, a technician must conduct tests to confirm the integrity of the system and ensure that it can operate safely and effectively. This often involves using a leak detection method, such as a pressure test or electronic leak detector, to ensure that all necessary repairs were successful. By confirming that no further leaks are present, the technician can proceed with confidence to reconnect the system and recharge it, knowing that it has been properly serviced and is fit for operation.
