How can electronic leak detectors help in diagnosing refrigerant line restrictions?

Electronic leak detectors are specialized tools that can detect refrigerant leaks and restrictions in HVAC systems. These detectors use sensors to identify the presence of refrigerant and can pinpoint the location of the leak or restriction. They can also help technicians detect smaller leaks that may not be visible to the naked eye. By using electronic leak detectors, technicians can quickly and accurately diagnose refrigerant line restrictions and develop an effective repair plan.
