forced air heat in mpls multilevel house. 1975 vintage. 2400sq/ft. no doors between levels so temp is very uneven on different levels. i need an all new system. natural gas furnace. high efficiency of course. does that mean multistage burner and VS fan? or is there a VS burner/VS fan unit out there?
