Compressor noise?

I took my car in to try to diagnose a heavy rumbling noise from the front of the engine compartment when starting from cold, after standing overnight. It lasts about a minute then subsides. I reckoned it might be the a/c compressor but there's plenty of other stuff in just that area, of course. We replaced the serpentine belt and both pulleys - one was definitely shot. Tensioner was OK, steering pump and alternator turned smoothly and quietly. About 1mm end play on compressor. A/c System had only 20% of the refrigerant gas it should, but wasn't empty
After that, I'm happy my belt is OK and I could now have cold air if I wanted it, but this morning I still had my noise. I really don't want to buy a new compressor as it is worth 50% of the car's paper value
Should mention that the noise does not go away if I turn the a/c to Econ. Turbo boost is reliable and up to spec. Any ideas, please?
