During a major energy upgrade that we recently completed we had two return ducts a 14 in the main house and a 12 return duct in the master bedroom. 2 improving ventilation in the attic and or insulating the attic floor to minimize the effect of attic heat and cold in the two season on the upper floor. This solution doesn t address the ductwork so it is an inferior solution compared to creating an unvented conditioned attic.
