Which statement about proper joint sealing in ductwork is true?

• A. Proper joining methods are critical for joints to remain leak free.
• B. Joints do not affect leaks.
• C. Leaks are unlikely in ductwork.
• D. Seals do not impact energy efficiency.

Answer: (A)

The main idea is that air leaks in ductwork mainly occur at joints, so using proper joining methods is essential to keep those joints leak-free. When joining techniques and sealing are done correctly, conditioned air stays inside the ducts where it belongs, maintaining the designed airflow and pressure. This reduces energy losses and helps the system operate efficiently, since the blower isn’t fighting leaks or pulling in unconditioned air. If joints aren’t sealed properly, leaks will occur, increasing energy use and potentially causing comfort issues and poor indoor air quality. Joints do affect leaks, leaks are common in ductwork, and seals do impact energy efficiency by reducing leakage.
