This customer attempted repairs on this unit, however, they left the compressor and refrigeration system exposed to the elements... outside overnight.  That's a good way to launch a compressor.  Ironically, they ended up putting a new compressor into this unit; a $2000 mistake.  Sometimes trying to save money costs you more in the long run.

This is the same unit, a week later... after they replaced the compressor, they put it back outside with the intake hose off of the engine... again, leaving the engine susceptible to water entry.  This can cause either internal rust inside the engine, or hydro lock the engine.  Again, while trying to save money, you can actually do more damage.
