Reactive Maintenance (run-to-fail): 

Preventative Maintenance: 

Condition Based Maintenance:

No regular maintenance - means no labor or part costs until failure occurs or under-performance is noticed

Key / Details

Costs of Reactive Maintenance can range from minor repairs to total replacement of machinery.  Therefore, it becomes difficult to predict the cost of Reactive Maintenance

Regular and routine inspections that look for wear and tear before symptoms appear.  Can also follow a plan of action created by the manufacturer of the equipment.  The costs of Preventative Maintenance programs are more accurate than Reactive Maintenance because everything is scheduled and you can plan for the purchasing of parts and maintenance tasks 

Expect to pay more for labor under Preventative Maintenance, so equipment inspections occur as scheduled.  However, those added labor costs may be offset by preventing major repairs and the increase in energy consumption from machines that do not operate at peak performance

Can detect potential problems early, saving you from unexpected expenses, less expensive and time-consuming than preventive maintenance, suitable for assets that need to run continuously, even during maintenance.  Reduces labor by using sensor equipment and other condition monitoring tools and can deliver cost savings of 10 to 40% compared with poor maintenance

Set-up costs associated with the Condition Based Maintenance programs that use condition-monitoring sensors

• Optimize equipment by rationalizing suppliers, utilize strategic or preferred suppliers to consolidate spending and employ non-OEM suppliers for non-critical equipment services
• Negotiate multi-year contracts with gradual CPI increases and assess the benefits of a Preventive Maintenance (PM) contract versus an all-inclusive mode
• Explore opportunities for self-performance, such as PMs and visual inspections
• Deploy the appropriate labor rate by skill-set required for the service, utilize non-union resources when union resources are not necessary for the service and ensure service delivery occurs during normal working hours to reduce overtime
• Hold landlords accountable for services as outlined in the lease
• Implement enhanced Building Management System (BMS) monitoring and control via ESI or an account-based equivalent to remotely monitor and control infrastructure, thereby reducing dispatches for temperature-related issues
  

Predictive Maintenance:

Is an innovative approach that evaluates potential issues that may arise with HVAC equipment and systems before they occur.  It indicates when technicians should perform maintenance tasks to avoid breakdowns and disruptions, as well as extend the life of the machinery.  Like Condition Based Maintenance can deliver maintenance savings, but also decrease breakdowns and boost productivity

Set-up costs and the initial outlay associated with Predictive Maintenance programs that use an array of IoT sensors can be high
