What is the difference between a rigid duct and flexible duct in terms of cleaning?

• A. Rigid ducts are easier to clean and maintain; flexible ducts can trap lint and are harder to clean.
• B. Flexible ducts are easier to clean than rigid.
• C. There is no difference.
• D. Rigid ducts trap more lint than flexible.

Answer: (A)

Cleaning dryer exhaust hinges on how the duct’s interior is shaped. Rigid ducts have smooth, straight runs that let lint slide out or be swept away with brushes and a vacuum, and their joints are easier to inspect and seal for thorough cleaning. Flexible ducts, especially those with accordion-like interiors, create ridges and more bends where lint can settle and snag, making it much harder to reach with cleaning tools. Because of these interior features, flexible ducts tend to trap more lint and are harder to clean, which increases fire risk and reduces airflow. So the idea that rigid ducts are easier to clean and maintain while flexible ducts are harder to clean is the best description. The notions that there’s no difference or that flexible is easier to clean don’t reflect how interior geometry affects cleaning access and lint accumulation.
