Another AC issues thread

Like a few others on here, I’ve been having some issues with my AC. My previous issue (no cold air at all), was due to a bad compressor. That was replaced about a month ago, and since then I never felt the air get as cold as it I believe it should. If I get the temp to 63F, on 90+ days the interior just doesn’t get as cold as my wife’s mdx. The interior does get cool, but not that frigid air that I expect when the temp is set so low.

Any thoughts on what might be causing this?

I logged the HVAC and attached some of the values.

Sorry for the crude image.

Also… just recently I threw a high pressure sensor fault and will be replacing that shortly.
