Work found on the roof of a local condo complex. Most of it was done by a property management firm.

 This unit was about to fall off the 4x4. Only about 1" of coil is supporting it. Hope it doesn't vibrate too much!

 This is one of the original units. Near as I could tell, still in use!

 A real impressive shot, unfortunately with a long lens from across the street. But fortunately for that compressor, it was somewhat leveled later on.
