    Just a note that your condenser can not be flushed. Generally when we do a compressor at my shop we change the condensor also.

    It all depends on what failed and how. If the compressor failed internally and started throwing debris through the system you'll need to replace the condenser, orifice tube and accumulator as well as flush all the lines. Pull the orifice tube and see if the screen is full of debris. If it's clean, you may be OK.

    ------------------------------------------ -----------100% CORRECT -

    IF the old compressor blew - and IF the orifice tube DOES have debris in it -

    I would STRONGLY recommend installing an in-line filter - ACDelco-15-1747
    to protect the new compressor -

    $26.87 - with free shipping -

    This is the inline filter I used. Catches the debris before it has a chance to clog the orifice tube. Installs in the liquid line.

    that one is OK - very small - and more expensive -
    but better than nothing -

    The orifice tube screen is a very fine mesh. Isn't that in itself a filter?

    well - yes - but - it is a "last-chance" type "filter"
    and it doesn't take very much to clog it up -

    my shop ALWAYS installed the in-line filter I pictured -
    VERY cheap insurance - and 99.999% effective -
    back then - many compressor suppliers REQUIRED one -
    as a condition of their warranty -

    Installs on the suction side yes? Don't most systems have a filter/accumulator/dryer on the low side? My thinking is it would be better to stop the debris before it entered the condensor and the orifice tube.

    most systems do not have any filter -
    which is why I suggested one -

    My thinking is it would be better to stop the debris
    before it entered the condensor and the orifice tube

    the most important thing -
    you MUST prevent debris from getting into the compressor -
    the only thing with moving parts -

    and it's much easier and safer tapping into the low pressure side -
    than messing with the high pressure side -

    Bought my compressor kit from these guys. Comes with the compressor (filled with 7oz. oil), orifice tube, accumulator/drier/filter and "o" ring kit. Pulled the radiator, condensor, alternator to get to the compressor. Not too bad of a job.
    I added a condensor and the inline filter.
    I was impressed the parts arrived the day after I ordered them!

    My AC works like new.
