Duct sealing is significant in air conditioning systems primarily because it helps reduce energy loss and improves the overall efficiency of the system. When ducts are poorly sealed, air can escape from the system before it reaches the intended rooms, which leads to increased energy consumption as the system works harder to maintain the desired temperature.

By ensuring that the ductwork is properly sealed, you minimize leaks that can account for significant energy losses, thereby enhancing the efficiency of the air conditioning system. This results in a more comfortable indoor environment while also lowering energy bills.

Sealing ducts does not directly relate to increasing the system’s weight, preventing sound transmission, or simply reducing operating costs without a focus on performance. While all these aspects can be relevant to some extent, they do not express the primary benefit of duct sealing in the context of energy savings and system efficiency.
