What is the impact of not sealing duct seams effectively?

Not sealing duct seams effectively leads to increased air leakage, which significantly impacts the overall efficiency and performance of the HVAC system. When seams are not properly sealed, conditioned air can escape through the gaps or cracks in the ductwork. This results in a higher volume of air that the HVAC system needs to produce in order to maintain the desired indoor temperature, leading to increased energy consumption.

Additionally, increased air leakage can cause uneven temperature distribution throughout the building, making some areas too hot or too cold. This can create discomfort for occupants and put additional strain on the heating and cooling systems, potentially leading to more frequent repairs and a shorter lifespan for the equipment. Proper sealing of duct seams is therefore essential for maintaining energy efficiency, effective air distribution, and overall HVAC system performance.
