Duct Leak Testing

Duct Leak Testing in 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 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 isn’t, 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?

Air can escape through improperly connected, disconnected, or deteriorating ductwork, resulting in insufficient conditioned air reaching your 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, indoor air quality may be at risk.

Frequently Asked Questions

National Environmental Balancing Bureau (NEBB) is a non-governmental organisation that is responsible for providing guidelines on the HVAC system of Testing, Adjusting, and Balancing (TAB). Qualified professionals and technicians that are certified by NEBB are the only people who can perform HVAC Duct Leak Testing.

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