As I have stated on the forum somewhere before I am in process of doing a (remodel) new install on my house. I am in need of a zone system but have just a question or two.
1.) What is the best zoning equipment to use which provides the best performance and least service history for the cost?
2.) Will I need a barometric dampner (I think that is what it's called) for any air not supplied to the zone calling?
I have a system which has a return in the floor near the mechanical closet and wondered what I needed to do for the times that the system is running but only on the smaller of the two zones? what happens to the supply air which is not being used by the system?
Thanks for any enlightenment you can provide!
