Default Ticking/Rattling Noise when AC is on

Hey guys! I got this weird sound going on whenever I turn my AC on. Its like a rattling or ticking noise from the engine bay. definitely noticeably different than our typical direct injection noise. its not constant and is always here and there, sometimes it makes alot of noise and sometimes it doesnt. Only happens when ac is on. any insight would be appreciated. thanks!

it’s the tensioner pulley but it’s normal. If you look at the pulleys you’ll see it moving a bit when it makes that sound but should be okay.
