For those who work on their A/C, how do you recover the refrigerant and evacuate the system so you can do repairs?
Does anyone own their own A/C recovery unit? Or do you take it to the local A/C shop?

What are the best strategies & what are the favorite tools?
For example, if you need to replace the compressor - what it the best DIY strategy?

BTW - if you want to buy R-12 you have to get EPA609 certification.
