Recharging and adding oil to a split system

[andrew97cobra]

I have a 2 year old Goodman split system with 2.5 ton A/C. When we were installing it, my father in law didn't do a good job on brazing one of the connections and I had a very tiny leak as a result. Over time, I lost most of the R-22 and some oil. I fixed the leak this past weekend and now it's time to recharge the system.

Since I lost some oil, I don't know how much is left. I know that the best solution would probably be to get the remaining oil out and to start from scratch, but how do I go about doing that? Would evacuating the system pull the oil out? Is removing the rest of the oil even necessary? Topping it off would be a guess as to how much needs to go back in.

Thanks for any pointers!

minor amount of oil loss, no need to worry. unless, you topped it off more than 3 times with refrigerant before repairing leak, then maybe. just make sure your refrigerant charge is correct. should add low pressure switch to prevent compessor damage in case charge leaks out again.
