Which is an example of corrective maintenance?

• A. Seasonal lawn care
• B. Fixing a malfunctioning HVAC system
• C. Painting the exterior
• D. Cleaning windows

Answer: (B)

Corrective maintenance is work performed after equipment has failed or isn’t functioning properly, with the goal of restoring it to normal operation. Fixing a malfunctioning HVAC system fits this idea because it directly repairs something that has stopped working. The other tasks are preventive or routine upkeep: seasonal lawn care helps maintain the landscape and prevent issues, painting the exterior protects surfaces and maintains curb appeal, and cleaning windows is regular cleaning to preserve appearance and light—none involve repairing a failed system.
