Possibly, I am quoting from the Compressor supplier who say on the invoice "Always replace the Expansion/Orifice Tube and Receiver Drier/Accumulator when replacing a compressor..." :-\ :-\ :-\

Right, I've just read that through, and as my system was working OK when it had gas, I'm assuming the the Expansion valve is probably OK. I think they are covering themselves in case the compressor change was due to system failure rather than a leak. I'll leave it for now, as if it does need changing, the extra cost should only be the valve then a regas. :y :y :y

They state it in case the compressor was a catastrophic high side failure resulting in debris in the system.

As Mark says, when my compressor failed (5 years ago) it spread crap throughout the system, we poured what looked like a sludge of iron filings out of the filter/drier. The expansion valve was replaced and when we blew some fluid through it more sludge came out. The system had to be flush cleaned for about 2 hours before all the sludge was out. IIRC total bill was just shy of a grand .. :(   

compressor, filter drier, expansion valve, flushing fluid, regas, labour :(
