How does proper dryer vent cleaning improve dryer performance?

• A. Increases energy consumption
• B. No impact on drying time
• C. Increases noise
• D. Reduces drying time, improves efficiency, prevents overheating

Answer: (D)

When a dryer vent is clean, hot air can move freely from the drum to the outside. Lint buildup in the vent creates resistance, causing backpressure that traps heat and moisture inside the dryer. That means the dryer has to run longer to achieve the same dryness, uses more energy, and can overheat the internal components. Cleaning the vent restores good airflow, so drying times shorten, the dryer operates more efficiently, and the risk of overheating decreases. In short, clear airflow directly improves performance, energy use, and safety.
