Your building may only need 1.5 to 3 tons depending on your geographical location and how well your insulation is. Hello Courtney, for duck sizing, you can check our article about HVAC flex duct sizing here. In short, 18″ flex ducts can handle 1300 CFM; that would be the most optimum option. A 3-ton unit would is adequately sized for a warehouse. We’re sorry; we don’t have the required know-how to answer the spiral reduction question.
