In some cases they can remove the sludge by flushing the component. In other cases they must replace the compromised components. Then they evacuate the system to remove all remaining moisture. Next, they add the factory recommended oil and refill the refrigerant using a special refrigerant scale. So you wind up with the proper amount of oil and a dry system that works like it came from the factory; something a DIY recharge kit can never accomplish.
