Preventive Maintenance
Preventive maintenance is a schedule of planned maintenance actions aimed at the prevention of breakdowns and failures. The primary goal of preventive
maintenance is to prevent the failure of equipment before it actually occurs. It is designed to preserve and enhance equipment reliability by replacing worn
components before they fail. Preventive maintenance activities include equipment checks, partial or complete overhauls at specified periods, oil changes,
lubrication, and etc. In addition, Galgon HVAC & Mechanical Qualified Service Technicians can record equipment deterioration so they know to replace or
repair worn parts before they cause system failure and downtime. The ideal preventive maintenance program would prevent all equipment failure before it
occurs. The objective is to be Proactive, NOT Reactive!
Value of Preventive Maintenance
There are multiple misconceptions about preventive maintenance. One such misconception is that PM is unduly costly. This logic dictates that it would cost
more for regularly scheduled downtime and maintenance than it would normally cost to operate equipment until repair is absolutely necessary. This may be
true for some components; however, one should compare not only the costs but the long-term benefits and savings associated with preventive maintenance.
Without preventive maintenance, for example, costs for lost production time, customer dissatisfaction and patient discomfort will be incurred from
unscheduled equipment breakdown. Also, preventive maintenance will result in savings due to an increase of effective system service life and Customer
Satisfaction.
Long-term benefits of preventive maintenance include:
• Improved system reliability.
• Decreased cost of replacement.
• Decreased system downtime.
• Increased customer satisfaction.
Long-term effects and cost comparisons usually favor preventive maintenance over performing maintenance actions only when the system fails.
