This has been an issue at DCA for a few summers now. I think its a mix of ground crews not having a checklist (or not following), the ground AC units being broken (aka MWAA's problem), and obviously, not wanting to run the APUs... although all airlines do this. Can't recall exactly, but pretty sure Delta has a reminder on the exterior Gate signs at ATL, 'HOOK UP, TURN OFF APU.'

Do Pilots need to flip any switches in the cockpit in order for the plane to use ground AC?
