It was a day-long course and a 4-hour test to get my EPA license for refrigerant. It's all about the safe recovery and reclaim process. The vac pumps shown above only pull vacuum. They do not recover the old refrigerant safely. That takes a $1200+ reclaimer pump and hoses and a empty tank.
An empty system can be charged with nitrogen to check for leaks. Never use air.
