I have a loud AC unit also on 24/7. I never heard them make any noise before. I thought they were supposed to power up and down with the rest of the unit, but i just picked up the one with the green light on it and its definitely vibrating a bit. I assume that means they've been spinning this whole time Ive had it. The green lights have always been on.
