Also, this particular home does not have any insulation in the walls (lucky me). I know some about blown-in insulation, but another unique feature of this home is that all the rooms have the heat registers at the base of exterior walls, not the floor. By base, I mean, like 6"-8" off the floor. Will the heat from the ducts in the lower walls pose a problem when the blown-in insulation is added?
