🔍 What Is Duct Leakage Testing?

Duct leakage testing involves pressurizing HVAC ductwork using calibrated test equipment and measuring the amount of air escaping through joints, seams, and connections. The measured leakage is compared against allowable limits defined by project specifications and recognized standards.

⚙ Why Duct Leakage Testing Is Important

• ✅ Improves HVAC system efficiency by reducing fan energy loss
  
  
• ✅ Prevents loss of conditioned air, lowering cooling & heating loads
  
  
• ✅ Helps maintain accurate air balancing and airflow distribution
  
  
• ✅ Ensures compliance with consultant, client & authority requirements
  
  
• ✅ Reduces noise, pressure imbalance & vibration in duct systems
  
  
• ✅ Minimizes dust infiltration and indoor air quality issues
  
  

🏗 When Is Duct Leakage Testing Required?

Duct leakage testing is typically required in the following situations:

• Before ceiling closure in commercial & institutional buildings
  
  
• Prior to HVAC system handover
  
  
• For high-pressure duct systems
  
  
• In critical environments such as:
  
  
  • Clean rooms
    
    
  • Laboratories
    
    
  • Hospitals & healthcare facilities
    
    
  • Data centers
    
    
• When explicitly specified by consultant drawings or specificatio

📐 Duct Leakage Testing Standards We Follow

We conduct testing in strict accordance with recognized international standards, including:

• SMACNA Duct Leakage Classes
  (Class 0.5, Class 1, Class 2, Class 3, etc.)
  
  
• DW/143 – UK HVAC ductwork specification
  
  
• ASHRAE 90.1 – Energy efficiency standard
  
  
• Project-specific or consultant-defined requirements
  
  

All testing is performed using calibrated instruments and documented for verification.

🧪 Our Duct Leakage Testing Process

1. Isolation and sealing of duct sections
   
   
2. Pressurization of ducts to specified test pressure
   
   
3. Measurement of airflow leakage rate
   
   
4. Comparison against allowable leakage class
   
   
5. Identification of excessive leakage points (if any)
   
   
6. Retesting after corrective sealing (if required)

📄 Reporting & Documentation

After testing, we provide a comprehensive duct leakage test report, including:

• Tested duct section details
  
  
• Test pressure & leakage class
  
  
• Measured leakage values
  
  
• Pass/Fail status
  
  
• Compliance statement
  
  
• Observations & recommendations (if applicable)
  
  

Reports are suitable for consultant approval, authority submission, and final handover documentation.
