As a leading provider of ventilation hygiene services, we have encountered numerous misconceptions and misunderstandings surrounding ductwork pressure testing.
In this month’s blog post, we are shedding some light on four of the most common misconceptions about this service. By dispelling these myths, we hope to help you gain a better understanding of just how important it is.
What is ductwork pressure testing?
Ductwork air leakage levels can be measured by ductwork pressure testing. This usually involves temporarily connecting a duct leakage tester in order to pressurise the ductwork, including duct-mounted components.
Airflow through the pressurising device creates an internal, uniform static pressure within the ductwork. This specific measurement aims to relate the pressure differential across the ductwork.
This pressure testing is critical because it allows us to identify issues within our customers’ systems which we can then fix.
Misconception One: Ductwork Pressure Testing is Unnecessary Expense
One common misconception is that ductwork pressure testing is an unnecessary expense, especially for new constructions or recently installed HVAC systems.
This myth overlooks the fact that even new installations may have flaws or inadequacies in the ductwork. Pressure testing can detect these issues early on, preventing future problems and ensuring optimal performance. If left untreated leaking ducts can significantly increase energy bills, reduce system capacity and performance as well as resulting in indoor air quality problems that can be dangerous.
By investing in ductwork pressure testing, you can save money in the long run by avoiding costly repairs, and also ensure that the air you’re breathing in is of a high quality.
Misconception Two: Pressure Testing is Only for Commercial Buildings
Another misconception is that ductwork pressure testing is only relevant for commercial buildings, where the systems are larger and more complex.
Whilst larger systems may require more monitoring this is again untrue as systems can have issues regardless of their size and even smaller systems will require maintenance. Most new build non-domestic buildings will now require a commercial air pressure test, as will large extensions to existing buildings.
Residential homes can benefit greatly from pressure testing as it enables homeowners to identify and rectify any ductwork leaks, which can lead to significant energy savings and improved indoor air quality. Research has shown that poor air tightness can be responsible for up to 40% of heat loss from buildings, affecting the comfort of those living there. Regular testing allows you to keep on top of any issues, regardless of building size!
Misconception Three: Pressure Testing Only Detects Leaks
Many people believe that the sole purpose of ductwork pressure testing is to detect leaks.
While leak detection is indeed a crucial aspect of the process, pressure testing offers a more comprehensive evaluation. It assesses the overall performance of the system, including issues such as improper insulation, inadequate airflow and suboptimal balancing.
As well as leaks, any design or manufacturing flaws will be found during this process. By uncovering these problems, pressure testing helps optimise the performance, efficiency and comfort of your HVAC system.
