Class Schedule

It is recommended that participants attend this class prior to attending the Advanced ACCA Manual D class. This class provides a review of the ACCA Residential Design System and approved software, Manual D procedure, and proper documentation. Learn how to achieve efficiency compliance while optimizing ductwork for competitive pricing and comfort. North American Technician Excellence (NATE) continuing education credits are available for this class.

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 instructor’s 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.

Many homeowners are considering changing ‘Gas Furnaces’ to ‘Heat Pumps’ to provide  residential heating and cooling.
The Training builds upon the ACCA Wrightsoft series and focuses on the Science of correct sizing of Heat pump systems and includes a Wrightoft computer lab portion.

The session builds upon Manual ‘J’ and provides a foundation upon which Manual ‘H’  will be built.
It is recommended that attendees bring their own laptop preloaded with the Wrightsoft Demo software

The course covers Basic concepts of duct design. Covers air flow dynamics and static pressures within the systems, defines and explains EL, friction rate, location, throw and spread of grilles, registers and diffusers. Includes a Software portion for Wrightsoft and will include Elite. The information covers efficiencies relating to design, installation as well concepts focusing on delivered efficiencies, operating points, fan and duct curves.
