A Complete Manual D Duct Design Module


Right-D® is the fast, easy-to-use residential duct design software that takes full advantage of ACCA's streamlined Manual D Method. With Right-Draw®, you can draw your duct design, or simply place the registers and let Right-D design your layout to eliminate the confusing spreadsheets. Even use the optional ductulator for friction rate calculations. Right-D requires at least one load calculation module in order to operate (Right-J®, Right-CommLoad™, Right-N® or Right-F280™.)

Bottom Line.

Right-D is a Manual D duct sizing and calculation!

With Right-D duct designs, the ducts are automatically sized based on the airflow and static pressure.


Set your preferences, draw your floorplan, and your duct design is practically done for you!

We Highly Encourage Using Right-Duct with Right-Draw. To have visual duct design, as shown above, you must own Right-Draw.
