it is common for these compressors to fail when r134 is used ...there life is about 4yrs ...


I had this compressor last 17yrs with r12 ...

the system needs a good chemical flushing before installing the new compressor ...that orifice tube screen gets dirty and the compressor suffers damage...

have an ac shop inspect for why this has failed and then take the correct recommended action..
