How do you properly size floor registers? I am Installing a 2 ton heat pump in a house that is about 1200 sqft. The rooms are pretty small, so I was planning on running 6" flex to all of the rooms except the living room and master bed which will get 8" flex. I've been googling but can't find a straight answer.
