Can I couple the (2) 4" aluminum vents into 1 common 4" vent?
I've always done separate runs.
I second that. It can be quite a pain though if your in a tight space and sometimes the HO doesn't like the looks of two vents side by side in the soffit or whatever but I've always run 'em separate.
I have 2 exhaust fans to wire and install.

Or am I better off doing 2 separate runs?
I'm a wierdo. Since I'm an electrician, I let the HVAC people do the venting.
This is why the mechanical contractor should install the fart fans.

Mag - I've put a "y" connector right close to the exterior vent and then connected two runs into that. Kind of a last resort thing if they don't want two vents, etc.
Also, it's usually far enough down the run that backdrafting would not be a problem.
x2 with that Tin said about low spots. Also, think about insulated ducting if it is in an attic area.
I was planning on doing it like I've always done it.... flexible aluminum.
Is that bad (really bad!) because the moisture meets the cold in air in the winter?
I want to do it like a pro.
