Mutli-zoned HVAC

I am in the planning stages of this project. I do not have any experience with HVAC systems

This is great information but is it worth the risk? It is better to find a professional HVAC Contractor in your area (see AirconditionerFeatures.Com Contractor Search as this forum blocks links). You can also attain a HVAC Certification for your planned project. Do-it-yourself is great, but let someone else evaluate if your qualified before you start experimenting with explosive fuels (Furnaces) , poisonous gasses (some Air Conditioners), or materials which cause other heath risks such as fiberglass.
