Long term lurker here... the more I look at these pictures the more things pop out at me.
Maybe my perspective is off, but that orange pipe looks like it would certainly place second to having that roof support right in the middle of the door.
The disconnect and starter for the compressor look brand new, but what the heck is that red wire snaking out of the disco?
The discharge pipe for the compressor goes an odd way, threading between the panel and the disconnect.
As for the concrete pad, everything in the room appears to be raised, maybe there are some issues with the sump pump/ drain.
Are thsoe chemicals I see stored behind the compressor, below the panel?
That panel looks far older than the compressor, maybe they replaced a smaller unit at some point, and notching the door is a rather poor solution.
Unfortunately, I would bet this is not an unusual condition for these types of installations. There could be enough work here to keep someone quite busy.
