Water has accumulated in my air conditioner...

Question

I have an HBLG5004 for a few years with no probs...until last night. It was making a sloshing noise (it does that sometimes when there is a bit of water accumulation). Well this time the fan was making a deep 'whirring' noise and was spitting little droplets of water out of the vent up top.

Should I just let this ****** dry out and start from there? Or is this a larger problem?
