This morning I was sitting at my desk typing up some material requisitions and all of a sudden water started pouring out of the vent above my desk, and my bosses desk. It was pouring. He threw his monitors and laptop off his desk, I dragged my stuff out of the way, grabbed a trash can and shoved it under the water. Caught about 4 gallons of water, not including what had already poured on the floor and desk tops!
The office building, is really 3 double wide trailers bolted together. So there are 3 of those hvac units mounted on the ends, just so happens our office wall is the mounting point. We pulled the cover, and the A coil was frozen solid, and the ice had been melting off, and there must of been ice built up and was acting as a dam. It broke free and allowed the water to roll back out of our vent. Since ours was first in line, we got the water.
What a mess! Not something you expect to happen!
