<p>Hey, y'all, sorry if this is on the wrong forum; plumbing is as close to climate as I could find here.<br>As the name suggests, I have an attic, which is a great living space, except that it gets very hot in the summer. One ventilation from the air conditioner in the house does nothing. It has a huge front window, but it would be expensive and ugly to insert a window block.<br>However, there is a side crawl space through which a 4-inch hose with a dryer vent runs from the vent in the ceiling of the bathroom on the first floor, about ten feet away, and exits to the outside. It would be quite easy to install a window block in the wall between the attic and the utility room and attach its exhaust hose to the bathroom vent.<br>Will it be legal? Some manufacturers I've researched have cautioned against attaching window blocks to dryer vents, mainly because the exhaust hoses for air conditioners are 6 inches. Just wondering if anyone has done something like this in practice.<br>Thanks!<br></p>
