Just in case I'm not the only one not getting it, this is at least something to check when cleaning filters. Since I have had water leaks just about every where but, around the air conditioners I've not paid any attention to them. Today as the weather has been warming in Iowa I started addressing interior maintenance and thought I would check the bolts. None were even close to snug and several appeared hard to turn but, were still quite loose. To those of you who have mentioned this many times I finally got it, now what else hasn't sunk in.....
