I am about to embark on setting up a zoned system for my upstairs HVAC system. It's been hard to find resources that can help a DIYer. There are a few things I need help with and was hoping someone on this board may have the experience...
My ducting is flexible insulated duct work, and I can't figure out what the interior diameter of each hose is. The exterior diameter seems to be 12" and 9" for the hoses I will need to install dampers in. Anyone have experience doing this? I would like to order the dampers without having to rip stuff up to check the interior diameters.
Second question is the barometric bypass - Is it all I really need to protect my compressor? The upstairs will have 4 zones and is 1500 Sq feet. I am not sure of the size of the A/C unit.
Thanks in advance.
