What is a common reason for duct leakage?

• A. Improper sealing
• B. Incorrect sizing
• C. Excessive length
• D. High humidity

Answer: (A)

Improper sealing is a common cause of duct leakage because it can occur at various joints and connections within the ductwork. If the seams, joints, or connections are not adequately sealed, conditioned air can escape, leading to reduced efficiency in the HVAC system. This not only impacts the cooling and heating performance but can also increase energy costs as the system must work harder to maintain desired temperatures. Effective sealing materials, such as mastic tape or specialized duct sealants, are essential to ensure airtight connections. Addressing improper sealing during installation or maintenance can significantly improve the system's overall efficiency and effectiveness. This understanding is critical for HVAC professionals to deliver quality work and optimize system performance for their clients.
