Duct Work and Duct Insulation almost speaks for itself. Duct work is those long, silvery, metal tubes that carry your cool or warm air from the unit to the area to be conditioned. While not needed on most mini split systems, slim ducted and package units will require some, minor duct work to meet the runs into side rooms. We offer a variety of ducting from simple, solid metal runs, to flexible ducting. Both come insulated or uninsulated to meet what ever demands you might throw their way!
