How to Recover, Vacuum, and Charge an HVAC System | Step-by-Step Guide

In today’s video, I’ll walk you through, step by step, how to recover refrigerant into a recovery tank, how to pull a vacuum using two different methods, and how to charge the HVAC system with it on and off. This video is a bit longer than usual, but if you stick with it, you'll gain the confidence to handle HVAC systems the right way. Timecodes: 0:17 - What tools do we need to do a recovery? 2:12 - Make sure the hoses don't have restrictions so you can do a faster recovery. 7:00 - Purge the air out before you start the recovery. 11:39 - Using the molecular transformator to finish the recovery. 16:00 - Make sure to recover down to 0 psi and leave it for 5 more minutes to ensure all the vapor pressure is out. 17:17 - 30lb and 50lb tare weight and some simple math. 21:40 - Example of 50lb tank and doing the math to find out how much more refrigerant I can put in. 25:40 - Self-purge option on recovery machine. 27:10 - First Method: Pulling a vacuum using the gauges. 34:11- Second Method: Using the core removal tool. 43:45 - Charging the system when it's off in the HIGH side port. 48:05 - Reinstall the valve core into the pressure port. 52:17 - Passive recovery. 54:24 - Charging the system when it's on in the LOW side port. 56:55 - Recap #hvac #hvacr #refrigerant #r410a #vacuum #recovery #stepbystep #schradervalve #hvacinstall #servicetechnician #chargingrefrigerant #r22
