register vents

[hottaair]

I have a 4 ton 12 seer unit how many register vent can i run off this unit?

thats a very open ended question....the answer is as many as you have designed your entire system (including duct work) for.

[pauls heating &]

usually 1 each per run

4 tons=1600 cfm, diffrent run sizes carry diffrent cfm, not number of, but what size to how many, if all were 6" at 125 cfm each, you could have a total of 13, then depends upon length and static and all that goes into a properly designed duct system

in what world will a 6" pipe run 125 cfm?

[wahoo]

This is not a DIY board. You need to get an experienced HVAC person to install this. He'll know how to size the ductwork.:.02:
