Does your heat and AC systems use the same ducting? If so, are there dampeners or someway to stop back feeding the system that is not in use? My concern when using heat or AC is loosing air through the system that is not in use. My idea is to build or have built a plenum that allows me to block air flow to the system not in use. Something similar to a dust collection blast gate.
