Manual D is the layout and sizing of your all NEW duct-work. This is typically required when you are installing new ductwork, as in an addition, new construction etc.

Manual D Calculation :  We lay out each individual room in the house and size the ducts to meet the required CFM of each room.   

Manual J & D Calculations: You can certainly tell us where you want the ducts and registers OR we lay them out for you.
