Class Schedule

Description:

It is recommended that participants attend the ACCA Manual J Equipment Sizing and Selection and ACCA Manual D Duct Design courses prior to attending this class. This class will step beyond the introduction to ACCA Manual D to more advanced topics, including how to perform Manual D calculations both manually and using the official Wrightsoft ACCA computer software program. This class will be presented using computers for hands-on training. Participants will perform group exercises and have the opportunity to work on individual problems with the instructors assistance. Class topics will cover – Homes with multiple HVAC systems – Two-story homes with single systems – Using the computer program to generate room-by-room load calculations and select HVAC equipment – How to use the graphic design module of the computer software, which automatically calculates room-by-room load calculations and provides Manual D duct design. North American Technician Excellence (NATE) continuing education credits are available for this course.
