Duct leakage testing is a diagnostic tool used to measure the airtightness of ductwork. A calibrated fan is installed in a duct, and the other openings to the duct are sealed. The fan then creates a negative pressure in the duct, which forces air to leak in through any cracks or gaps. The amount of air that leaks in is measured, and this information is used to calculate the duct’s leakage rate.

Duct leakage testing can help identify areas of air leakage in ductwork, which can then be sealed to improve the efficiency of the HVAC system.

Here are some of the benefits of having duct leakage testing performed:

  • Identify air leaks that are wasting energy
  • Improve indoor air quality
  • Reduce moisture condensation problems
  • Extend the life of your HVAC system

Duct Leakage Test

A duct leakage testing begins by sealing all the ducts and registers with duct mask tape on both the supply and return side.

Duct Leakage Testing

After the registers are sealed we attached the duct tester to either the unit itself or a main return.

Duct Leakage Test

The ducts are then depressurized to a Pascal of 25. With the ducts depressurized we can use the nanometer to get a reading of the duct leakage.
