Re: Modular rack question.
You are correct...the Freedom and ARS (or any open sided rack system) needs to have a heated room as they don't have anything to really hold the heat near the tub. In an AC home I would suggest a plastic rack system (or home built one) just something where all sides of the tub are enclosed as it will hold the heat much better.
I have an ARS rack and love it...but when I first got it (AC home) it never could get the tub temps stable (it fluctuated with the house temp). So I built another rack and stored my ARS one...now I have a heated room and use both racks.
Hope this helps.
