Duct Leakage Testing: Basics and Beyond

Explore the basics of duct leakage testing. Learn how to set-up the home and equipment to quantify both total duct leakage and duct leakage to the outside. You will also learn the Half Nelson test. We will talk about ways to track down duct leaks along with using the duct leakage equipment to measure total system airflow. Best practices for duct testing including safety considerations, pressurization testing versus depressurization testing and any situations that prohibit using the duct testing equipment.
