How often should you inspect rooftop fan units?

• A. Weekly
• B. Daily
• C. Monthly
• D. Annually

Answer: (B)

Regular checks of rooftop fan units are essential to keep ventilation reliable and catch problems before they cause downtime or safety issues. Inspecting them daily is best because these systems run continuously, are exposed to weather, dust, and debris, and small faults can develop quickly into bigger failures. A daily review helps you confirm the unit is actually operating, listen for unusual noises, notice abnormal vibration, check that airflow is steady, and look for obvious issues like loose electrical connections, overheating, or blockages. If you only inspect weekly, monthly, or annually, a developing problem could go unnoticed long enough to cause a sudden failure or reduced indoor air quality. A daily check keeps the system in good shape and supports safe, consistent ventilation.
