Duct Conversion
I am interested in changing my round existing furnace duct to rectangular. Do I need to just match sq. in so the size stays the same. Also, how can I tell if I can add another diffuser and not overload the furnace? Thanks

Duct size
Why do you want too?????????????? Do you have the room for duct? Where is the pipe now. Can you rework the plenum and have room to do so. You will fine that you need more or bigger duct to get the same sq " as the round has in it. Its not that another out let will overload the furnace its more like do you have the cfm for it. also. info info ED

If you post the round sized you want to change, I'll reply with the standard sizes you would have to use. You may not get all the information you need that way but it will get you started.
