Preventive Maintenance Programs At Engineering Excellence, HVAC Preventive Maintenance (PM) is not a necessary evil; it's a means to an end. That end is lowering your "total cost" – which involves energy consumption, equipment replacement and life spans, unscheduled maintenance and repairs, as well as preventive maintenance. This cluster of variables is something we call "the mix". As a facility manager, it’s something you call "your job". An Engineering Excellence PM Program is simply a migration path for helping you manage this complex mix of variables in order to lower your overall cost.     Every PM program is literally tailored to your budget and equipment requirements. Year one may be focused on bringing existing equipment up to optimum efficiency, while subsequent years may simply require minimal maintenance. Whatever the case, an Engineering Excellence PM Program will help you answer important questions like: How thorough should your PMs be? Should every facility receive the same level of maintenance? When does the cost of a PM outweigh its benefit to equipment life or energy consumption? When should you replace equipment as a cost-avoidance strategy? Should you add service labor or parts coverage? Does it make sense to extend the original warranty beyond the first year on all new equipment? Ultimately, you determine the level of preventive maintenance and service you will receive. As part of the process, Engineering Excellence representatives will consult with you to design an effective program, complete with options, strategies and information that will help you "optimize your mechanical assets."
