Which statement best describes the concept of planned maintenance?

• A. It is reactive and urgent.
• B. It consists of scheduled preventive maintenance tasks that occur regularly.
• C. It is optional and only applied to new equipment.
• D. It is performed only after a failure.

Answer: (B)

Planned maintenance is a proactive, scheduled program of preventive tasks performed at regular intervals to keep HVAC equipment running reliably and efficiently and to catch issues before they cause failures. In practice, this means routine inspections, cleaning, lubrication, filter changes, coil cleaning, checking refrigerant levels and pressures, belt/tension checks, electrical connections, and control calibrations—all planned and scheduled rather than done after something breaks. That focus on regular, preemptive care is why the statement describing scheduled preventive maintenance tasks that occur regularly best captures the concept: it emphasizes preventing problems through a planned, ongoing program. The other approaches describe reactive failure-based work, optional maintenance, or maintenance only after a fault, which do not align with planned maintenance.
