Duct Blaster Test
A duct blaster test measures the air tightness of ductwork by pressurizing or depressurizing the system with a calibrated fan. The airflow required to maintain pressure reveals how much air is leaking, helping technicians target sealing improvements that boost comfort and efficiency.
💡 Key Takeaways
- ✓A duct blaster test measures the air tightness of ductwork by pressurizing or depressurizing the system with a calibrated fan. The airflow required to maintain pressure reveals how much air is leaking, helping technicians target sealing improvements that boost comfort and efficiency.
- ✓Leaky ducts can waste 20–30% of conditioned air.
- ✓Testing helps meet energy‑code requirements in new builds.
- ✓Sealing leaks improves airflow balance and indoor air quality.
