Why is it important to seal joints with proper metal tape or clamps?

• A. To improve the aesthetics of the ductwork.
• B. To prevent air leaks and lint escape, maintaining proper airflow.
• C. To make duct joints easier to remove.
• D. To reduce the exterior vent noise.

Answer: (B)

Keeping joints sealed with proper metal tape or clamps ensures there are no air leaks or lint escapes from the dryer exhaust. This is important because leaks reduce the system’s effective airflow, which means longer drying times, higher energy use, and more wear on the dryer as it struggles to push air through a leaky duct. Sealing also keeps lint contained, reducing the risk of lint buildup in inaccessible areas—a major fire hazard in dryer exhaust systems. Using metal tape rated for high temperatures and sturdy clamps provides a durable, heat-resistant seal that resists vibration and moisture. The other options don’t address the main function here: aesthetics, easier disassembly, or simple noise reduction aren’t the primary reasons to seal joints.
