[tcb] Re: Does anybody know anybody who works on aftermarket AC systems?

  
  I heard r134a is less efficient in the old r12 systems, and mine lacks enough 
efficiency as it is. r134a also tends to leak from older systems. I think I 
heard it was more pressurized?  

  I thought I could just get a new, small, $200 compressor that would cool 
better and draw less power than the older unit. But the more I study this, the 
more confusing it becomes. Maybe I should just bite the bullet, find some old 
R12 and keep it original.    ?  ?

Is it r12 or r134a?  Either way if you crack open the system you     have to 
replace the drier.  If it's r12 you might as well convert it     to r134a 
because r12 is very expensive.  If you convert you have to     replace the 
drier, oil, orifice and flush the system.
I just replaced the ac clutch on my wife's car and they wanted $1100     to do 
it.  I did it myself in a day and $200 in parts.  If you do it     yourself you 
can get a vacuum pump at Harbor Freight for about $100.

Good luck either way.
