That means that if you install a 90% efficient furnace, your system efficiency would be just over 60%. Another way to look at this is that ducts lose 25–40% of the energy that moves through them. Just from a practical standpoint it makes sense to improve the delivery system. Shorter, straighter, better engineered and installed ductwork will improve delivery efficiency.
