Air Distribution Basics and Duct Design

COURSE NO: M03-044
Air Distribution Basics and Duct Design
Course Highlights

This online engineering PDH course discusses the information needed to design the air distribution system to deliver the proper amount of conditioned air to a space in an energy efficient house.


The heating, ventilation, and air-conditioning (HVAC) system is arguably the most complex system installed in a house and is responsible for a substantial component of the total house energy use. A properly sized HVAC system will provide the desired comfort and will run efficiently. Right-sizing an HVAC system includes the selection of equipment and the design of the air distribution system to meet the accurate predicted heating and cooling loads of the house. This process begins with an accurate understanding of the heating and cooling loads on a space; however, a full HVAC design involves more than just the load estimate calculation; the load calculation is the first step of the iterative HVAC design procedure.


This 3 PDH online course is intended for mechanical engineers, architects, contractors and other professionals interested in learning more about air distribution and duct design for energy efficient homes.
Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Learning the different terminologies and concepts of HVAC systems that relate to air distribution
  • Understanding the performance criteria related to air distribution systems, which include temperature mixing and uniformity, supply outlets, and noise considerations
  • Understanding the design benefits of integrating the HVAC system into the early schematic design phase of the house
  • Familiarizing with the design principles of distribution systems, which include pressure drop, supply requirements, return air design, supply air outlets, duct layout, and duct sizes
