AC Unit Low on Refrigerant! Leak Found!

In this HVACR Video, I Show How I knew this Air Conditioner was Low on Refrigerant and How I found The Leak using the Superior Signal, Ultrasonic "VPE GN Pro" leak detector! I go over how to Measure the Refrigerant Charge Levels to tell if you are Under Charged. This was a very small leak that would be hard to find without this leak detector. This form of leak detection will work for small or large leaks, any refrigerant, and even nitrogen pressure tests. I have had much success with this tool compared to multiple electronic heated diode sniffers.
