HVAC/Duct Sizing introduces the weatherization professional to the home survey, Manual J load calculations, types of distribution systems, and equipment selection. Common duct design and installation problems will be identified and addressed and the concept of the house as a system will be stressed. State-of-the-art technology is used in both the classroom and labs to provide students with a high quality learning environment. Students will model heating and cooling loads using basic computational computer software in the classroom and design appropriate distribution systems. Students will be evaluated on their ability to model heating and cooling loads with the computer software.
