Can an AC compressor (92 244 with R34) be very noisy just due to insufficient charge? The system blows cold, but the compressor does overcycle. It is alledgedly only 3 years old and installed with the R34 upgrade by previous owner.
Or, is it as I suspect, toast -- a victum of infant mortality.

Afraid not (the noise from being low, that is) - but I'm not expert enough to say you should replace your compressor. The noise and overcycling could be overcharge, though, probably from the beginning. With R-12 I was able to charge with guages, with sight glass or by ear (fill it 'til the compressor cycling barely stops.) I tried that with my son's R-134a system, in spite of the experts saying it has to be done by weight with the expensive machine. The experts were right (duh!) I went right past the proper charge point and got about 40% too much 134a in it. The compressor rattled and cycled off every few seconds. A pro evacuated it and recharged it for $76 US and it works perfectly.
Getting a recommendation from friends and taking it to a shop that has the machine is your best bet at this point.
