Duct Leak Testing

Duct Leak Testing company Malaysia

Any building’s HVAC system is meant to preserve indoor air quality and maintain a suitable temperature. Not only does this entail heating or cooling the air to the temperature set by the thermostat user, but it also entails filtering air and maintaining the internal air of your building free of outside toxins. If the HVAC system is in good functioning order, it will easily accomplish both aims. If it is not, not only will dangerous pollutants infiltrate your building’s indoor air space, but you will also be wasting energy and potentially losing a significant amount of money each month on energy bills. Therefore, it is critical to perform air duct leakage testing.

What could possibly go wrong with HVAC duct system?

In some buildings, air escapes through improperly connected, disconnected, or deteriorating ductwork, resulting in insufficient conditioned air reaching your living or workspace, leaving the environment excessively warm or chilly. If the return duct system is leaking, it may be sucking in stale or filthy air from the outside and distributing it throughout the structure. If the supply duct system is leaking, the building may get depressurized, and outside air may be pulled into the ducting and distributed throughout the structure. In either case, the interior air quality may be compromised.

Duct Leak Testing Process

These are the steps that is taken to test HVAC duct leakage according to National Environmental Balancing Bureau (NEBB):

Identify the portion of ducting that will be tested - Calculated surface area
Seal ductwork
Pressurize ductwork to specified level
Measure flow required to maintain duct
Compare to standards

National Environmental Balancing Bureau (NEBB) is a non-governmental organization that responsible on providing guidelines for HVAC system of Testing, Adjusting, and Balancing (TAB). A qualified professionals and technicians that certified by NEBB are the only person who can access on performing HVAC duct leak testing.

  • Poor indoor air quality
  • Comfort issues
  • Energy maximization
  • When a new heating and/or air conditioning unit is installed
  • When a heating and/or air conditioning unit undergoes a diagnostic tune-up
  • Duct testing, on the other hand, can be undertaken at any time, regardless of whether new energy-efficient equipment is being installed
