What is Ductwork Pressure Testing?
Ductwork pressure testing is a critical procedure that assesses the air tightness and integrity of duct systems in buildings. It identifies any leaks or weaknesses within the ductwork, ensuring the system meets the necessary standards and operates efficiently. Duct leakage testing is essential for maintaining optimal performance and energy efficiency in HVAC systems. Our team has a wealth of experience covering construction, healthcare, residential, engineering and pharmaceutical sectors, amongst others.
Why is Pressure Testing Important?
Ductwork pressure testing is vital for several reasons:
-
- Energy Efficiency: Leaky ducts can lead to significant energy losses, causing HVAC systems to work harder and consume more energy. By identifying and sealing leaks, pressure testing enhances energy efficiency, reducing utility costs.
- Indoor Air Quality: Properly sealed ductwork ensures that air flows correctly through the system, preventing contaminants from entering and maintaining high indoor air quality.
- Compliance: Adhering to DW144 standards ensures compliance with industry regulations, avoiding potential fines and legal issues.
System Performance: Identifying and rectifying leaks improves HVAC systems' overall performance, helping them attain optimal capacity.
What is the Pressure Testing Procedure?
The ductwork pressure testing procedure involves several steps to ensure thorough examination and accurate results:
- Preparation: The duct system is sealed, and gauges are attached to measure the air pressure within.
- Testing: Air is pumped into the ducts to create pressure, and the system is monitored for any pressure drops, which indicate leaks.
- Leak Detection: Areas where pressure drops are identified, and the extent of leakage is measured.
- Analysis: The data collected is analysed to determine if the system meets the required standards for air tightness.
Once completed, clients receive a full report on:
- Classification of ductwork
- Ductwork surface area
- Leakage rates
- Duration of pressure test
- Reporting of defects found
- Test certification & report
Should the ductwork fail to achieve the leakage requirements, we have a variety of solutions.
Resolving HVAC Leakage Issues
When ductwork leakage exceeds allowable limits, corrective measures to restore system integrity are essential. Traditional methods for reducing ductwork leakage include adding clamps, fixings, and mastic to increase air tightness. While these processes can improve the overall airtightness of a system, they are often time-consuming and may not be feasible for areas that are difficult to reach, such as above ceilings, behind walls, and other building services.
For challenging scenarios where dramatic improvement to airtightness is required, our Aeroseal technology offers an efficient and effective resolution. The machine can seal leaks from the inside, which can drastically reduce leakage by 99%.
