Plenum swap effect on AC?

Plenum swap effect on AC?
So I finally replaced my plenum with the thick aluminum one (the old steel one that was on it didnt have any leaks, was sealed nice and strong, so ended up being more of a longevity repair ;(...) Anywho, I got it all replaced and back in and it runs fine like it did before, but now my AC doesn't seem to be blowing cold at all. I can hear the compressor kick on on the AC settings, and I can feel the line under the hood getting very cold, but I don't notice any change whatsoever between the fan and AC modes, prior to this I remember my AC being super cold.
I know I didn't unplug any of the AC lines, as I just laid the compressor out of the way when I did the swap, any ideas what else could be causing this?

You may have created a slight refrigerant leak when you moved the A/C compressor out of the way to perform the intake repair or a slow leak may have already been in-place, since A/C only really gets run during the warmer months. Like was mentioned, you can put some A/C gauges on it to check the pressures in the system to see if it's low on refrigerant.

I've got no heat, heater core is bypassed since it was leaking, and im not about to break my ALMOST perfectly uncracked dash to try and replace it haha, but I live in the south, so I haven't needed it at all, only dropped below freezing for a few days awhile back.
Truck is a 2001.
I don't think it has a slow leak in the refrigerant as it was blowing cold prior to replacing the plenum, and the lines are still getting cold like they were before. Its just that cold air isn't reaching the inside of the truck. I'm assuming I would feel SOME change since even if it was low on refrigerant, its cooling the lines, so id expect SOME difference even if it was slight, but there was no difference what so ever.

Yeah there's been no change in the intensity of the air in relation to its fan speed settings. The only difference is I don't notice it getting cold when its on AC :/

Truck had a motor swap last spring, everything was fine, got a new condenser and complete system recharge and refill over the summer and it has held for months just the same as day 1 until now. I guess anything is possible, but it just seems very very very unlikely. If it was a slow leak, id expect lower performance, not complete lack of, and if it was a major leak, I would expect the lines to not get cold, as there wouldn't be refrigerant.
I suppose I can check anyways though.
