We are excited to offer this Air Flow and Duct Sizing sheet metal class to our Winstel Controls contractors. This class was so well received last year that we immediately tried to make arrangements to repeat the class this year. The class is presented by Jim Mayer of Southwark Metal Manufacturing. This class sold out last year in 2 weeks. We expect this class to fill up fast again so please book early!

Course Description:

This course provides all the primary information and theory needed to understand how air flows in a residential HVAC system. It explains how the quantity of flow is calculated based on the energy demand for a particular residence and the effect that the system components have on this air flow. This course also provides more advanced information and theory needed to calculate the proper duct size in a residential forced air system. It will explain how basic air flow fundamentals must be used along with complete information on the dwelling, all installation components, proposed equipment, and best practices for installation.
