They pull me back in. Room was high 90's. I shut off a bunch of lights. Turned AC off. In 15 minutes the ice melted. I tuned it back on again, it cooled the room. I turned on a few lights and let it run all night. This morning more of the same only thicker. I turned it off. It melted again, and I turned it back on. I looked at if from outside. It was making a rattling sound. Water was pouring out the back over the edge. I had noticed the lack of a drain in the sleeve when I installed it. On a hunch, I got my drill and drilled a few small holes in the drain pan. Water poured out. The thing stopped rattling. I think I installed it at too shallow an angle and the designed drain system wasn't working, causing water to pool in the tray deep enough to catch the tips of the fan blades, which was causing the rattling sound. I think the ice is because of too much humidity. First it was raining outside when this happened. Second, I had transferred plants and the floor was soaked. Third, I misted the shit out of the plants with the hose (which I rarely use) because of the heat. To top it off one of the reservoirs had overfilled and spilled about 3 gallons of water on the floor. I didn't think to check the RH but it is routinely in the 90's at night and 60's during the day.
