We provide professional duct sizing and air distribution design services to achieve optimal airflow performance across HVAC systems. Our engineering calculations determine appropriate duct dimensions based on required airflow rates, air velocities, friction losses, and system pressure requirements, while accounting for fittings, branches, transitions, and terminal devices. Using coordinated 3D BIM/Revit models and established design methodologies in accordance with applicable ASHRAE and SMACNA standards, we deliver efficient, well-balanced duct work systems that minimize energy consumption, control noise levels, and simplify installation and coordination.
