Duct Air Leakage Test
Definition
Duct Air Leakage Test or Duct Blaster Testing measures air leakage in HVAC ducts.
Leaky ducts can waste energy and reduce indoor air quality. This test ensures your ductwork is sealed properly, especially after new installations or repairs.
How it Works
1. The HVAC ductwork is tested by sealing off all HVAC registers except one
2. Pressurizing the ductwork system by using a manometer, fan and a device to monitor the air flow and pressure.
3. The pressure achieved should be CFM 25
4. A Report is issued to certify the rate of leakage.
Independent Testing
A Duct Air Leakage Test is required by the NC Building Code for all new and replacement HVAC systems. An independent qualified tester performs the Duct Air Leakage Test to determine the rate of Air Leakage. The compliance standard is 5%. If air leakage in the system is greater than 5%, then remedial work is needed to reduce energy use and cost.
