I just built a Shade for my AC unit - PVC pipe and shade cloth - looks like it is keeping it about 2Deg cooler in the shade now.. hopefully that will help I have a fin comb in the mail so that I can straighten out the fins that my 3 year old has pressed over and get even better efficiency out of it. I don't know that I would want to spray my system with water the water here is very hard and vinegar doesn't touch it
