Sorry, the pics aren't too clear, but it's 3 phase and the wires are in aluminum tubing. The stat wires are.... were taped to the tubing. The tubing goes into a larger conduit down through the roof which isn't sealed, so rain goes in it.
The unit which they replaced was sitting on those plastic legs, but they didn't bother putting anything under the Rheem.
Most of the insulation on the suction line is missing. Discharge line from unit (5 ton) comes out of unit at 3/8 and immediately goes into 5/8. Single story building, 40' lineset.
Looks like they got a little close to the flue cap with the crane
