I was investigating why is one of the air vents so loud when AC is running. Turned out the air duct is not actually behind the vent, but to the side of it.

This is looking from the vent towards the duct: https://imgur.com/LoVmJLB

Is this a common thing? The casing for the grille (left of the picture, the white thing) is restricting air flow a bit and making the whole vent kinda loud.

I am thinking to get a dremel and just cut off the extra casing that’s serving no purpose

Edit: mixed up return vs supply. This is a supply vent.

    Seems like an unintended design flaw that just kinda causes more headaches than it should. Ideally you’d want smooth airflow through the duct and grille but your setup is generating turbulence.

    I’d clean that up and also try fabbing up some cardboard inserts to get rid of the hard angles in there. Smooth that airflow out!

    Just an idea anyway…

      Cardboard sounds good. I dremeled some of the casing, that has reduced the noise a decent bit, but still very much louder than the other vents.

      I thought only software engineers do hacks in production.
