I don't know what you mean by a 'set' charge, please explain the phrase.
I first changed the compressor to a four seasons, didnt fix it of course, and then replaced with another new delco unit, tube and dryer while having the same problem.

Additionally, I had a leak in the high side port shortly after, so I checked the condensor while it was empty of freon again, vaaced it and recharged onlt to have the same problem.
Set charge is the amount of R-134a the system calls for.
Like on the ac information sticker on dryer.

How much did you put in it when you recharged it?
