My AC compressor broke and consequently will have to replace compressor, drier, expansion, and condenser. I will flush lines of course. Do I have to replace the evaporator or flush it? Can I just leave it alone and replace everything else (items above) since I do not see any online postings of replacing or cleaning the evaporator after compressor failure that likely results in debris in A/C system.

 

I have never serviced an evaporator in the case of doing other AC work. What you have listed (compressor/drier/expansion) will be plenty.

 

going by what was stated in the OP

unsure of yr of car, what car...still wouldn't hurt to do so since you're pulling it out anyways
