DuctCalc is the easy way to compile a duct material take-off. You can input a project using sheet metal as the material, the program will do the entire math for you and calculated pounds of metal, gauge of metal required, feet of slips and drives, square foot of duct wrap and the number of hangers required to hang the duct. You've got your project bid completed and your customer says how much is the cost if we did the job with fiberglass.

Design Master HVAC is an integrated HVAC building design and drafting program that runs on top of AutoCAD. Drafting features include single-line and double-line 2D ductwork with automatic fittings and 3D ductwork. Duct sizing calculations include constant pressure drop, constant velocity, and static regain. Pressure drop in the duct system can also be calculated. Building load calculations are done using the ASHRAE CLTD method.
