HVAC duct layout drawings are detailed plans illustrating the placement and configuration of ductwork in a building's HVAC system. These drawings guide the installation process, ensuring efficient and effective heating, ventilation, and air conditioning. Created with specialized software, they consider factors like airflow, pressure, and energy efficiency. HVAC duct layout drawings promote coordination among various disciplines and prevent conflicts with other building elements, contributing to the seamless integration of HVAC systems into overall building design.
