I should add that he says this will work (he's 100% sure). He said that he plans on adding new duct work in the unfinished basement and vents in the floor above the basement. He said that the duct work that is in the basement now is not sufficient and that the air is going straight up to the higher floors. This system is to include dampers and electronic devices in each room upstairs that will indicate the need for air in those rooms as necessary. Does this sound reasonable? I am wondering what something like this costs. I feel so upset that I am having to pay him for something he should have noticed before he put my new furnace/ac/heat pump system in.
