Why is duct cleaning required?

• A. To increase duct noise suppression.
• B. To remove grease buildup, maintain airflow, and reduce fire risk.
• C. To improve cooling only.
• D. To reduce energy consumption by 50%.],

Answer: (B)

Grease-laden ductwork presents a serious fire hazard and can impede the ventilation system. Cleaning removes the grease buildup in hoods, ducts, and related components, reducing the fuel available for a potential fire and helping prevent flames from spreading through the ductwork. It also keeps the exhaust path clear, which preserves proper airflow and prevents back-drafting or reduced ventilation that can compromise safety and performance. This is why cleaning is required: to lower fire risk and maintain effective ventilation. It isn’t primarily about noise reduction, cooling, or a specific energy-savings target.
