Did he check to see if he has power going to the compressor?
Did he install the correct compressor?
Did he check amp draw for the compressor?

Fail to start advice

Is it a combination fan / hermetic run capacitor ?If it is i have seen bad capacitors rite out of the box.Have him check his wiring again common and run wire reversals are bad.If it is having low voltage conditions at start try a Potential and start capacitor start kit with the MFD/Volt range recommended by the compressor manufacture.I would stay away from PTCR type (Aka Hotdog)

HAHA I did that once. ugh, I felt like a idiot, I knew right away that I put the CFM on the terminal for the COMP on the cap when I heard the fan start up and it was running faster and harder than I thought it should. I reversed the wiring and all worked well.

I actually like skrewing up if it doesnt cost a lot, its helps me to learn from mistakes.
