it's probably not a bearing if the sound is not always heard. bearing noise is almost always consistent.

YOu can localize it by taking the aircon belt off and start the engine see if the noise still exist.

My idler bearing was changed just yesterday. I did a test drive with the mechanic just 1 or 2 kms and it seemed okay. When driving along EDSA i suddenly experienced a halt though i was stepping on the gas pedal at no. 3 gear, and it continued even when I shift to gear 1 or 2, until i reported in the ofc this a.m. Is there a connection with the change of idler? What could have gone wrong? Last week it was the velocity joint that was replaced by the same mechanic, starting to doubt him but this maybe unfounded if there's no connection between the idler and the gas pedal/acceleration.
