I have the same problem and am considering taking my new macbook air 13.3 back in for a replacement. If you google this problem you will see that it is widespread and they will replace it... however does the cost of replacing it outweigh the annoyance? Resetting evertyhing is a pretty big pain.

They just used compressed air and blew on the spacebar? My Macbook Air is days old, there hasn't been time for debris to get underneath. @Macintoshes, what did you find out from the genius bar? I might get a chance to stop tomorrow and will udpate if I can otherwise it will be some time before I can get in due to travel. Thanks to all who are posting regarding this issue.

I just delt with it, as the problem was minor, and wasnt noticeable only when in areas of utter silence, but after acouple more days the (spacebar) seemed to adujst and the noise was less, and become fainter till it was no more, but before I decided to just ignore it and let it work itself out I did some research of course
And my research lead to the conclusion that apple have had problems with the macbook air 11-13 inch models reason for this was the spacebar was not responsive in some cases so apple adjusted the space bar and tried to fix the problem, the problem was (the spacebar) was pressed to the point of no response during production, where it was less or not responsive in some cases, and there for the adjustment has thus caused another issue altogether where the space bar has been adjusted but has to much response in the mechanism causing the sound that we are all hearing if only for a short while.
My adivce is this jose, do not under any circumstances try or attempt to remove the spacebar by yourself, the 2012 macbook air was somehow designed so that no keys can be removed without the entire keyboard being replaced, I suggest you wait 2-3 days as I did and let it adjust on its own, but if the noise is not improving by any means I strongly suggest taking it in to the apple store of purchase before the 14 day period and getting a replacement.
anyhow I hope that my advice has helped you in anyway possible.

Still squeaking like crazy. I under a Bestbuy 90 day return policy so I am going to get this swapped out. It is unbareable. Has anyone had any luck with resolving this without returning it?
