After any component failure you have to flush out each component separately, which means breaking open all connections flushing all the parts individually (condenser,evaporator, and all lines). Blow remainder of flush solvent out, let system dry. Install NEW orifice tube, add proper amount of new style pag oil. Reassemble system, install accumulator or drier LAST (accumulator as a desiccant that starts absorbing moisture)

If you did have a "Compressor Failure" it was coming apart pumping crap all through the system before it went out completely.

During this conversion you MUST change ALL the o rings to 134 A compatible style. If not they will leak.

These are the reason for pumping your system down after it has been opened up,

*completely eliminates any air from the system
*any remaining moisture will boil into vapor and be eliminated during the process
*will partially tell you if you have any leaks,
(should hold between 28" and 30" of vacuum)

If you just replace the compressor and orifice tube , without doing the steps above it will fail again.

After you get your $1000. estimate we can walk you through doing your repair yourself for 1/2 the money.
