supply ventg noise?

I recently had my a coil replaced as part of a condenser swap and one supply vent seems to be loud… It’s not an odd noise like somethings rattling … it’s just air blowing noise as if there is to much air coming through making the noise… Anyone know what might be causing this? It’s weird because every other vent seems to be the same as before the coil swap … Went from a A coil to N-coil, if that makes a difference. When I go and listen to the blower, in the furnace, it’s just as quiet as before… But this one vent, closest to the blower has definitely gotten louder… What should I look for? Might slowing the blower speed help?

Thanks!
