What are the effects of duct leakage on system performance?

Duct leakage significantly impacts the performance of HVAC systems, primarily leading to increased energy costs and reduced heating or cooling efficiency. When ducts have leaks, conditioned air escapes before it reaches the intended spaces. This results in the HVAC system working harder to maintain the desired temperature, as it compensates for the lost air. Consequently, this higher demand leads to increased energy consumption, driving up utility bills.

Moreover, the loss of conditioned air can lead to an imbalance within the home or building, where some areas receive insufficient heating or cooling, leading to discomfort. The system also has to run longer to counteract this inefficiency, which not only increases energy costs but can also lead to earlier wear and tear on the equipment, affecting its longevity and performance.

This scenario highlights the importance of sealing ductwork properly to ensure optimal HVAC system performance, energy efficiency, and comfort within the living or working environment.
