What I did to solve that problem after searching in this forum was to raise the A/C setting.

I raised mine to 75 degrees F and it stopped the noise.

In other words, you reduce the load on the A/C preventing it from blasting at full fan speed.

If it's still the original, time for a new belt. Even if it is newer, it could be glazed and no longer pliable, causing the squeal.
