Well I am going make my first attempt to fix my a/c, its getting hot here in Houston and its now my dd. I decided I was going to just tell you guys what I was going to do and if someone wants to chime in that would be great. First off I belive my system is completely out of r12, the reason I think it still has r12 is there are no r134 adapters on the compressor. The old compressor looked like it had a bad leak around the clutch and also the low side. I pressed the valve to check for pressure because there was nothing in the sight glass on the drier and nothing came out. Is it safe to assume that all the refrigerant is out of the system and I can move to the next step of the a/c repair? Or, is there most likely some residual in the system and I should get it evacuated? Depending on some feedback about whether the system is emty or not ( if there is still r12 left in the system I will get it properly evacuated) like I said nothing came out of the valves when I pressed them for a check ie.. it all leaked out the compressor. Regardless the system will be emty when its serviced.
So I ordered a new compressor from Rex as well as a dryer, o-ring kit. After replacing the compressor and dryer as well as the o-rings next I'm going to rent a manifold and vacuum pump. At this time I'm going to put a vacuum on the system for about an hour hopefully holding a vacuum of about 30. If the gauges stay about that then would assume the system has no leaks. Now, I was told by Rex that the compressor already has oil in it so I should not have to add any for the r12. So next I would recharge the system with the fsm recommendation in the low side of system.. Any thoughts would be appreciated and hopefully it can help someone in the future. By the way I got the EPA 609 cert to buy r12 so if you guys know of any place to get some let me know.
