[FAQ] HOW TO DRAIN REFRIGERANT OUT OF AN AC SYSTEM (DIY)
Now this not only apply to car a/c but will apply to all refrigeration systems at home or industrial use.
FACT: The refrigerant is a substance that has a very low boiling point, about 10degC (50degF). This means at ambient temperatures, it is at gaseous state. To drain it without letting it escape to the atmosphere, you must change its state to liquid and collected in a sealed container.
Things needed:
1. Refrigerant tank
2. Recharging hose
3. Bucket
4. A lot of ice
5. 6 pack/buffallo wings (optional)
The process is very simple. Just connect the recharging hose to the refrigerant tank, and the other end to the suction side of your a/c line. Then place the tank in a bucket full of ice and set it at the lowest level possible with respect to the a/c system. Wait about 30 min to 1 hour, depending on how much refrigerant you want to extract and you're done!
The a/c system is now evacuated from refrigerant and is in vacuum. Just be sure to use the appropriate tank. On average the a/c system of medium size cars is about 4KG. You must use a tank with a capacity of more than 4KG and so on.
Hope this post can be helpful to HT members someday.

Sounds good on paper, but I don't think this will fully evacuate the lines. There will always be coolent in the lines unless you have the system properly purged. Furthermore, I am pretty sure that this procedure would not even be legal in PA. To do this you have to have a lisence and the proper equipment.
What do you do with the coolant after you drain it?

This will not get 100% but it is the best next thing to taking the car to the professional shop. I don't know the laws in your area but honestly it will do negligible effect to the atmosphere. After you drain it, you can re-charge it when you're done servicing.
Well I do not suggest doing this in areas where the environmental laws are strictly implemented. But there are areas in the world where you can do this with out thinking about the law.

when i took out my ac system.. i used a few tools.. a axe, and sockets and wrenches. That stuff comes out QUICK. Made a nice cloud of stuff as well
