How To Refill R22 AC With Subcooling Method

How to refill refrigerant in a home AC or air conditioner. In this video I recharge a R22 unit with refrigerant using the subcooling method. I show the recharge or refill process and explain how to do it properly depending on what metering device the unit has. TXV or other. The AC condenser had a small leak which was fixed before filming the video.
