When you have new duct work installed under your house, do you typically get a new main trunk, or do they simply attach flex duct arms to an existing trunk? My home is a rectangular ranch with a rather long trunk made of sheet metal down the middle of the house. :rolleyes:

Thanks for trying to help Ed. Sorry I didn't provide enough details. I guess this is a question I will ask my local installer tomorrow.

You want to make sure you seal it up and put a good vapor barrier down on the ground. Also If he is going to run the duct out more and add more runs to it. I just think or feel it should be bigger. But thats from here I dont know.;) ED;)
