Rooftop fan units should be inspected how often?

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

Answer: (A)

Rooftop fan units are exposed to weather and are a key part of building ventilation, so small issues can quickly impact indoor air quality, safety, and equipment operation. Inspecting them daily helps you catch problems while they’re still easy to fix and before they cause downtime or safety hazards. A quick daily check should verify that the unit is powered, listen for any unusual noises or vibrations, and look for obvious signs of trouble such as loose panels, loose or damaged wiring, debris blocking the intake or exhaust, signs of water intrusion, or ice buildup. If something looks off, you can address or flag it for service right away, preventing more serious failures and protecting occupants. Keep in mind that more in-depth maintenance tasks—like lubrication, belt or bearing checks, and filter changes—are scheduled separately, but daily checks establish a timely, proactive approach to keeping the system safe and functional.
