ASE Question Of the Month
Which is correct?
You’re correct if you answered D!
Answer D is only partly correct. Whenever replacing a compressor, whether it’s for a catastrophic failure or just died of old age, it is imperative that the debris in the system be removed to prevent premature failure of the new one. Flushing is one way to do that BUT - most modern heat exchangers cannot be flushed because of their multiple flow path design. Additionally, lines with inline filters or mufflers cannot be flushed. Any component that can't be flushed, should be replaced along with the old compressor. And don't forget the drier or accumulator!
