My original plan was to disconnect it on a Saturday and reconnect it the next day at my new apartment.
However, after going through Toritoribe's posts, I'm starting to wonder if it's worth the hassle. If AC units didn't cost so much, I wouldn't mind even if I did screw up, as I could chalk it down as having learnt something, but it seems like I underestimated how difficult it would be.
It's not like I don't have the money to have it professionally done, but I am so used to doing everything myself that it seems like such a waste, but maybe I should just swallow my pride on this one... I'll go through Toriroribe'S posts more thouroughly and decide then on what to do.
Either way, I truly appreciate the effort, Toritoribe, and the concern, DoctorP!
