I don't understand your dealers reasoning. Why do they put the dump capability on the AC units if you aren't suppose to use them???????
I use mine when I want more cooling in that area. Plus I've owned a couple units that didn't have ducting, so that was the way it was used---dumped !!
You might want to take a mirror and flashlight and look in the ducting to see if the ends are closed off and sealed. If not have your dealer seal them up cause it's just blowing your cold air into the attic. You might also pull each of the dispersal rings off and look in there to see if they sealed around where it hooks into the duct.
