if you want to do a second floor of a home with a mini duct less, and lets say its got 3 to 4 bedrooms and bath. the area calls for 2 tons cooling, is it decent to put it in one bedroom and let it blow thru open doors to other rooms as long as it doesn't exceed the throw distance, since putting them in every room isn't that feasible and costly. i know it works good because of open floor plan on first floor.i was curious if other contractors have done this.
