The Leak Detector: Slow Down to Find the Leak
In this instructional monologue, Mike Plezia teaches viewers how to effectively use an electronic refrigerant leak detector. He explains that the most common error is moving the probe too quickly, which prevents the sensor from sampling the air and can cause leaks to be missed. He recommends sweeping the probe at roughly one inch per second and keeping the tip about a quarter inch from the surface. Because refrigerant is heavier than air, he advises checking the underside of lines and fittings. He also stresses the importance of zeroing the detector in clean air, turning off nearby fans to avoid dispersing leaks, and keeping the probe tip clean from oil and moisture. The overarching message is that patience, not speed, enables the tool to locate leaks reliably, and the speaker encourages sharing this knowledge with others.
