You can install the most expensive and efficient HVAC solution in your building but if your ducting system and ventilation infrastructure is poorly designed and installed, it will significantly impact the performance of your heating or cooling system. It has been reported that the loss can be as much as 40%. This is a well known issue, yet it is sometimes omitted in the design phase of projects.
The ducting network is an integral part of the overall solution as it is used to channel hot or cold air throughout the building. Ducting requires maintenance and sometimes its integrity is compromised because of extensive moves and changes conducted over time that get misaligned with the original HVAC system output specification.
