Thanks for the elaboration; I was thinking BFE was a reference to the rural areas near Cairo, Illinois
I see no problem with mounting a disconnect adjacent to the equipment it serves. It needs to be accessible while the unit is being worked on.
I'll bet this mounting is an attempt to make the unit less vulnerable to thieves. They may have also been trying to reduce line length, which has a major effect on the efficiency (SEER) rating of the system.
I'd also be more concerned with whatever is UNDER the unit. "Accessible" becomes moot if the area itself is blocked. (There's a reason I keep pruning shears on the truck).
