2 Hose Vacuum Pump Procedure VS 1 Hose Vacuum Pump Setup for HVAC!

In this HVAC Training Video, I show How to set up and Perform a Vacuum on an Air Conditioner. I time how long it takes to perform a vacuum using the two hose method and then I break the vacuum with nitrogen to 0 psi. I then time how long it takes to perform a vacuum using the single vacuum hose set up and then I break the vacuum with refrigerant from the bottle. I use valve core removal tools to remove the Schrader valves during the vacuum. Supervision is needed by a licensed HVACR Tech while performing tasks as Experience and Apprenticeship garners Wisdom and Safety.
