The first thing you need to know is the cooling BTU requirement for the room. From that number total cfm
can be calculated.CFM will dictate the number and sizes of
ducts. To reduce vent noise you can go with larger ducts and registers and fewer of them. Use insulated flex duct. If you have room to snake the duct around instead of running it straight you can reduce noise further. Don't forget to install returns. You can use ductboard or flexduct for this to reduce noise further. Finally, have canvas vibration joints installed at the blower housing if any sheet metal ducts are used.
How will you heat this room?
