    How can anyone condemn a compressor without testing? My guess is either you have the low voltage from indoors wired wrong to the contactor or maybe you've blown a fuse on the low voltage side indoors.

    First of all, find another tech. There are steps to follow when troubleshooting. He sounds like a salesman instead of a tech.
    Did you replace the contactor with one of the same voltage? Did you check the voltage at the coil leads? Was this a new contactor? Did you check the continuity of the contactor coil? There is always a lot of troubleshooting to do with control work. It only takes one issue to affect the entire unit.
