Guest guest Posted April 10, 2006 Report Share Posted April 10, 2006 Hello, We use a window unit AC to cool our home. If you have one of these, I would be quite cautious. I know of no really good way to clean them. They should be designed so that a person could open the interior ducts and squirrel cage fan to clean. The squirrel cage fan should even be removable. But nobody thinks of mold in designing these things. It's just make them as cheap as you can. Maybe buying a cheap one every two years is the real answer? Anyway, keeping the humidity low in your house helps, as that is what feeds mold growth on the duct work. I have seen older units spitting out black mold particles into the house the size of marbles(!) The owner did not know what they were, however, and thought they were just pieces of insulation that was old and cracking. Sheesh ! I would also be VERY alert to whether the vent was opened or closed to the outside. It should be kept CLOSED ! Window unit AC's are built to throw water from a drain pan onto heat dissipation coils, if they don't do this their life is shortened and they may quickly burn out. However, the drain pan is a really good breeding ground for molds. So to suck air through a vent, over the drain pan, which can be full of mold, is just about the worst situation an engineer could design for human health, in the way these machines are used in the real world. With the vent CLOSED, however, there should be little problem as most of the mold would be on the outside of the house (at least that is my belief from observation). Well, I'm no expert, but that's my 2 cents from experience. Zippy Quote Link to comment Share on other sites More sharing options...
