Thanks guys, lots of very good information here, I did much research overnight and this morning regarding sub cool and superheat and it seems it is a solid way to diagnose the actual charge of refrigerant doing work in the system instead of just pressures. Which could as listed above, have some air in it due to osmosis or tampering. While vacuuming the system and filling it again would be the best way about this, I really want to try and figure this one out before throwing the towel and doing that. Bit hard to reply to every single comment but taking all into account.
So knowing that and with the videos posted above, I attached two temperature probes one to each port, it seems it depends on the system manufacturer where they want you to take this reading if before the compressor or right after the valve so I did it like the guy in the video.. also wrapped a rag around it to maybe hopefully insulate the readout some and we can adjust for them being hotter than in reality as it’s measured in the riser pipe of the evap.
The numbers are these:
High side
145F saturation at the gauge set for the condenser
123F measured at the port with the probe
This leads to:
23° Subcool if I’m measuring correctly
Low side
40F saturation at the gauge set
80F at the probe
This leads to:
40° Superheat.
That seems like a pretty stark difference. I found this other video showing how to do it and diagnose with the readings. The picture on white paper is a screenshot from it. By what he says I need to add some r134 to the system. As George also pointed out from his charts. I might be on the low end of the pressures for a day in the 90s in Florida.
Here is a small picture spam of probe location and readouts.
