Hi my compressor locked down or at least the clutch pully. Long story short they is no pressure on the system an it s a R-134a system. So I bought a brand new compressor with clutch pully. The accumulator/drier (on fire wall). The orfice tube, pag oil came with the compressor, and complete o rings. I was told rule of thumb is to always replace the accumulator/drier when you replace a compressor. So I did. My question is now I've heard the condenser can NOT be flushed. And neither can lines that have the little round muffler/filter? So do I need to buy every part to make system new why would they sell flush kits? I just need all the help I can get I have worked in ac for homes for years so I have vacume pump an gauges to do the evacuating an re charge its just all I've done is brand new installs? ? Never been on service depo so I don't know if I could successfully get all trash out of the system. . If the compressor exploded
