Where can you find specifications on ducting?

The ASHRAE Handbook is a comprehensive resource for HVAC professionals, covering a wide range of topics including duct design, ventilation, and indoor air quality. However, for specific ducting design and layout, ACCA Manual D is the most relevant choice.

ACCA Manual D provides detailed guidelines on the proper sizing and design of duct systems, ensuring optimal airflow and system efficiency. It includes calculations for duct size based on various factors such as air volume, friction loss, and sound considerations, which are essential for creating a well-functioning duct system. This manual is specifically tailored for contractors and engineers working on residential and light commercial systems, making it the go-to reference for proper ducting specifications.

While the other resources mentioned, like the ASHRAE Handbook, National Fire Codes, and Local Building Codes, contain valuable information related to HVAC systems, they do not focus solely on ducting design as ACCA Manual D does.
