Be compliant with NC Code get a Duct Blaster Test and Duct Air Leakage Report.
Duct Blaster Testing
Definition
A diagnostic Duct Blaster Test measures Air Leakage in HVAC Ducts.
Independent Testing
A Duct Blaster Test is required by the NC Building Code for all new and replacement HVAC systems. An independent qualified tester performs the Duct Blaster 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.
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 which is ____
4. A Report is issued to certify the rate of leakage.
