Duct leakage testing is a critical step in ensuring optimal HVAC system performance. When your ducts are leaky, conditioned air escapes, leading to energy waste, discomfort, and increased utility bills. The 2018 International Residential Code (IRC) and International Energy Conservation Code (IECC) emphasize comprehensive duct sealing, especially for ducts located outside the thermal envelope.
Duct Blaster Installation: A duct blaster (or duct blower) is a portable fan that attaches to your duct system. Registers and grilles are sealed, and the fan creates positive pressure within the ducts, forcing air out of any leaks.
Pressure Measurement: A high-accuracy gauge measures both duct pressure (in Pascals - Pa) and airflow (in cubic feet per minute - CFM). The fan speed increases to attain a pressure of 25 Pa in the ducts. Leaky ducts require a higher flow rate to achieve this pressure compared to tight ducts.
Total Duct Leakage Measurement: The result of a Total Duct Leakage test is expressed as CFM25—the amount of airflow required to pressurize the ducts to 25 Pa of pressure.
The 2018 IRC/IECC specifies different leakage limits based on the conditioned floor area (CFA) of the house. These limits apply to projects following a prescriptive compliance pathway. Projects following a performance or Energy Rating Index (ERI) pathway can trade off higher duct leakage for improved performance in other areas.
