I've had something similar in the past, but hard to tell for sure based on your description. First thing I would make sure would be to ensure all the vents are fully open on the dash. I've had a sneaky passenger close one before and it made a weird whistling the next time I used AC. Thought I had an issue, but it was simply partially closed.
EDIT: another thing I just thought of: Check your cabin filter. maybe some debris is on that! (Its behind the glovebox)
