Preventive Maintenance or Wait For Failure

Preventive maintenance can be described as maintenance of equipment or systems before fault occurs. It can be divided into two subgroups:

     • planned maintenance
     • condition-based maintenance. 

The main difference of subgroups is determination of maintenance time, or determination of moment when maintenance should be performed.

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 actually fail. Preventive maintenance activities include equipment checks, filter replacement, partial or complete overhauls at specified periods, lubrication and so on.

While preventive maintenance is generally considered to be worthwhile, there are risks such as equipment failure or human error involved when performing preventive maintenance, just as in any maintenance operation. Preventive maintenance as scheduled overhaul or scheduled replacement provides two of the three proactive failure management policies available to the maintenance engineer.

Common methods of determining what Preventive (or other) failure management policies should be applied are; OEM recommendations, requirements of codes and legislation within a jurisdiction, what an "expert" thinks ought to be done, or the maintenance that's already done to similar equipment, and most important measured values and performance indications.

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.

Why wait for a failure to occur? Schedule your Preventative Maintenance visit at least once a year to assure the problem free operation of your air conditioner.
