I have a recurring wet spot in my bedroom floor. It happened the day after the swamp coller was turned on. The wet spot is in the middle of the floor only. What can it be and what do we do to fix it?

Are you on a slab? Is the spot warm? Does the spot go away when the cooler's shut off? Let me know. Tom

Are there any lines to the swamp cooler bear this area, above or below.
