We have a 3006wk with only one 15k AC and it is not enough for this East Coast heat. It worked fine in CA but I think the humidity along with the 95+ temps is too much. We put Reflextix in most of the windows and that helps but the only thing that really helps is getting it in shade. I am thinking about adding a 2nd AC in the bedroom also or possibly a portable unit and create a vent to the outside. There have been some recent and old threads on "pimpin" the AC and expanding the ducting that I want to try first. Just need to wait till the weather cools off enough to do it...
