Does R22 have Refrigerant oil in it?
My issue is I had a leak in a 3.5 ton Seer 14 system with a Scroll compressor (Heil HAC442AKA4) and in pumping down the unit I took out about 5 oz of refrigerant oil out. I did not put it back since I was told that the R22 cylinders had oil in them. In checking around I could not confirm this. Now I'm not sure what to do. I don't want to put too much oil in and I don't want to burn the unit up or reduce its efficiency.
For those who asked, I have a recovery unit. I did not pump it all the way down since I locked off the valves. And I had a professional look at it after it was installed. Thats where I got the information on the R22. NOW can I get some useable information!
