How to do a Pump Down on an Air Conditioner ( HVAC )

How to do a pump down on an air conditioner ( HVAC ). In this video I explain what a pump down is and how it works, along with pumping down an AC unit using the steps I explained. This should only be done by HVAC technicians and microchannel condenser coils should never be put into a pump down because that can cause them to leak. Manufacturers of r410A ac condenser units also don't recommend putting those air conditioner systems into a pump down either since that refrigerant has higher pressures and a pump down can lead to leaks.
