What ducting size do I use for a 3 1/2 or 4 ton AC unit. Also, if I have a 4 ton unit in my house now and keep in mind that the AC unit is 15 years old and the house living sq ft is 1880 is a 4 ton to much?

Tom: [Forton’s 00:00:00] good. If he has the system in the house now, the duct work will work for it. I cannot size ducts. It’s not that simple. There’s a “ductulator” that they use. It really is. I’m not lying to you. Anybody, if you know how to use a ductulator, they’ll figure out the run and the size and all that good stuff. The size of the room, this kind of thing. As far as Forton, Forton would be a good aggressive system to put in there. I like the idea of being a little aggressive of your sizing.
