Differences between Preventative, Predictive, and Breakdown Maintenance?
Learn more about the differences between preventative, predictive, and breakdown maintenance. What’s best for your team?
Example: Scheduled maintenance. Replacing filters on an HVAC every 6 months.
Preventative maintenance is work done on a repeating schedule to prevent failures or breakdowns. This could include monthly inspections, parts replacements, or detection reporting. The goal of preventative maintenance is to detect and avoid issues before they become an issue.
Breakdown or Reactive Maintenance
Example: Wait until your HVAC stops working and call a technician to come fix it.
Breakdown maintenance is reacting defensively to breakdowns and unexpected occurrences.
Example: Having sensors installed in the HVAC machine to tell us operating efficiency and expected efficiency to tell us when we need to replace filters
Predictive maintenance is understanding a piece of equipment, why it may be failing, and addressing issues before they become a problem. Predictive maintenance is becoming proactive and measuring when a piece of equipment could fail and the different modes of failure.
The difference really is in being reactive or proactive. Breakdown maintenance (reactive) occurs only when a machine stops functioning while
Predictive (proactive) seeks to ensure the machine is always working through regular check ups.
Most of the time reactive maintenance takes longer for a technician to tend to as the technician has to trouble shoot what’s going on. the parts needed can be extremely expensive (sometimes the entire machine needs to be replaced).
We encourage predictive because you can gauge the health of your equipment and always be informed about its well being.
