Aircon compressor whine after a hard run

[DaveyLC]

Strangely I've not had any problems since that evening I was giving it "billy big balls".. I'm having the system flushed, gassed and oiled on the weekend though.

These two photos show the result of the flushing of my system after the compressor had seized. The flushing liquid is Shellite and is suitably murky when stirred up. You can see the pile of iron filings settled in the bottom of the beaker in the second photo if you look closely enough. This is what the first garage failed to remove so it is no wonder the replacement compressor died with all that ironmongery running in the refrigerant.
