   What is a duct leakage tester?

   • Duct leakage testers are used in residential single family, residential multi-family, and commercial buildings that have a forced air delivery systems for heating and cooling. A basic duct leakage testing system includes three components: a calibrated fan, a register sealing system, and a device to measure fan flow and building pressure.

   How do you test duct leakage?

   • So, once you’ve measured the amount of air moving through the fan, you’ve quantified the duct leakage at the test pressure. For duct leakage testing, the standard pressure used is 25 Pascals, which is close to the operating pressure of a typical duct system.

   How does a duct leakage test work?

   • The tighter the ductwork system (e.g. fewer holes), the less air is needed from the fan to create a change in the ductwork pressure. A duct leakage test can be performed by either pressurizing or depressurizing the ductwork.

   A duct leakage tester is a diagnostic tool designed to measure the airtightness of forced air heating, ventilating and air-conditioning (HVAC) ductwork. A duct leakage tester consists of a calibrated fan for measuring an air flow rate and a pressure sensing device to measure the pressure created by the fan flow.
