I used to install AC systems when I was younger. To be honest, was always told the p-trap and vent for the sink was was good enough. Any access near the coil was for clean out and was capped. But that was also 20+ years ago.
Did find this website with some interesting info on this.
Good info on the drain setup. Specifically where the vent should be.
I do think the p-trap you have is not ideal. You should probably get an actual sloping trap and not have the 90’s.

I have had the unit serviced a couple different times and the “professionals” didn’t mention anything about it being wrong. It just puzzling that the water didn’t drain back into overflow pan and outside thru the viewing pipe
