Can't do it. There are too many obstacles to this supposed DIY job. If you have a different experience, please let know.

First, I will assume that you agree that the job should be done correctly and within the EPA rules (not releasing the old gas into the atmosphere).

Problems...

• I cannot find a good manifold set to do the job with. I've tried two manifold sets, they both leak. The first from the hoses, the second from the block. OK, I "only" paid $59 for the Manifold, but really is it too much to ask that they don't leak? After all that is critical to their use. I see other kits available for $49 - $250 but they all look like they are manufactured by the same folks.
• I cannot get a small tank to vacuum the old gas into and even if I did, there is no place to take the gas. A Small tank is about $80. But then what. I called around and the AC shops tell me they cannot take the gas because they don't know where it came from/what it is.
• I can get a shop to evacuate the system for me, but for what they charge for this service, I might as well get them to recharge too. The shops that are willing to evacuate my system for me, charge the same amount as they would to do a evac, test, and refill. About $99.
• There are no recycling shops to take the old 134A. In my town, I can easily recycle old motor oil, but although you are not permitted to "otherwise" dispose of these items, nobody private or government will accept:
  • Antifreeze
  • R134A, R12, or any other refrigerant.
  • Pressure treated wood.

For all the trouble, I have come to the conclusion that this is one job that is not worth the trouble. Tomorrow, I will go have the system professionally sucked out and refilled. Hopefully they will find that the system is still tight and all the components are good. Otherwise I will have to pay the $99 to get it tested, Replace whatever is broken, then pay another $99 again to evac and refill.

Bummer.
