You've some valid details, however it is wrong to dismiss the phenomenon of HVAC methods with ductwork located in unconditioned attics. In Texas in which I Reside this is a approximately ubiquitous observe. If we set in a lot more than a specific level of insulation, it would turn into extremely hard to use the attic for storage, or simply to stroll securely towards the AC for services.
