Just replaced my compressor and went back with "Freeze 12". It's different than R12 but closer to the real thing than 134. The shop that bled the system for me claimed that, converting to 134 dramatically increases the head pressure that the system operates at. Freeze is cheap and it seems to be doing a great job.
If you have more than one A/C vehicle I think it's best to buy the gages & related vac stuff ($100 +/-) & recharge yourself.
HTH JOhn
Where did you find a set of gages AND a vacuum pump for $100 +/-? Let me know since I wouldn't mind a vacuum pump for under $100. Gages last time I looked were nearly $100 and a decent vacuum pump was up around $500! After all that you still don't have a leak detector or a scale to dispense the right amount of R134a (remember R134a foams even if the amount is correct unlike R12).
Remember, you need a vacuum pump not just a compressor if you want to do it right and get maximum efficiency from the A/C system. A compressor simply doesn't evacuate the system sufficiently (-26" Hg on the compressor vs -30" Hg with the vacuum pump).
No, I'm not an HVAC tech though I do know some about it.
