Andy/Kari/Brad - is the chiller constantly noise or only when it kicks in? I am thinking about getting 1/4hp one for my 90gal setup. At this size it would be a bit of overkill for my size of the tank so it shouldn’t kick in that often and not for too long I guess? Or am I all wrong?

Yes mine would need to be in living area as well since I live in condo.
