Duct Leakage Testing of HVACs
Duct leakage is one of the main reasons for an ineffective HVAC system in your building, contributing to a significantly higher electricity consumption than is necessary under normal operational specifications. We conduct comprehensive duct leakage testing of HVAC systems in NSW, ensuring that your building remains environmentally conscious and energy efficient.
Why Do a Duct Air Leakage Test
A newly installed air ducting system should always be tested for any leakage, and after that, it should be tested every few years. Damage to the ducts can be caused by a variety of reasons, like accidentally during the refurbishment of lights or ceilings or disintegration by chemical or biological agents.
Duct leakage testing is done by sealing the whole ventilation system, pressurising it and then measuring the results, determining how airtight the system is. The tracing of leaks is done by making the sealed-off segment smaller and smaller towards the main HVAC unit.
There are two accepted results of a duct air leakage test, being "leakage to outside" (LTO) and "total duct leakage" (TDL). The LTO test measures the amount of air leaking into unconditioned areas, like crawlspaces, attics, and conduits. The TDL test measures the whole system and uses a calibrated fan to pressurise the ductwork.
