I’ve got a cheap air conditioner that keeps filling up with water. The manual says that this is normal and that it will evaporate over time. Until it does the fan makes more noise than normal, which I’m assuming is the fan splashing in the water, and it’s quite annoying.

The manual says not to drill any drain holes, but it is so tempting to do so. Whenever the noise gets to be too much I do pull the unit out of the window, and this tilting does cause it to drain, albeit inside the house, not outside.

Any suggestions as to how to keep this thing dry and quiet?
