Reactive Maintenance Explained: When Run-to-Failure Makes Sense (And When It Doesn't)

Reactive maintenance is the practice of repairing or restoring an asset only after it has failed or stopped functioning.  

Also referred to as run-to-failure or corrective maintenance, it requires no scheduled intervention - maintenance teams simply respond when something breaks down.  

Whether reactive maintenance is the right approach depends entirely on the asset, its criticality, and the potential consequences of failure.

That's the honest answer. Not every asset deserves a planned maintenance programme, and blindly applying preventive measures to low-risk equipment wastes time and money.  

But reactive maintenance also carries real risks when applied in the wrong context - risks that facilities managers in Australia and New Zealand are increasingly being asked to account for.

What Is Reactive Maintenance, Exactly?

Reactive maintenance (sometimes called breakdown maintenance or corrective maintenance) is triggered by a failure event rather than a schedule. The sequence is simple:

1. Asset fails or performance drops below acceptable threshold

2. A fault is reported or detected

3. A work order is raised

4. A technician is dispatched to diagnose and repair

5. The asset is returned to service

No inspection. No prediction. No pre-emptive action. Just respond, repair, and resume.

This contrasts directly with preventive maintenance (scheduled servicing) and predictive maintenance (condition-based monitoring), both of which aim to catch problems before they occur. Reactive maintenance sits at the other end of the spectrum - it accepts failure as a starting point rather than something to prevent.

When Does Run-to-Failure Actually Make Sense?

Reactive maintenance gets a bad reputation, but for certain low-priority asset classes, it is entirely defensible as a deliberate strategy.  

Here's when it legitimately makes sense:

• The asset is non-critical. If failure causes no safety risk, no significant disruption, and no downstream impact on operations, reactive maintenance may be all you need. Think light globes in a storage room or a spare office printer.

• The cost of prevention exceeds the cost of failure. If a piece of equipment costs $200 to replace but $500 per year to service preventively, run-to-failure is the economically rational choice.

• Redundancy is in place. When a backup system automatically takes over upon failure - a secondary pump, a failover server, a redundant air handling unit - reactive maintenance on the primary asset carries minimal consequence.

• The asset has a predictable failure profile. Some components simply wear out at a known rate. Replacing them reactively, with spares readily on hand, can be more efficient than scheduling inspections that rarely find anything wrong.

• Failure is easily and quickly corrected. If a repair takes 20 minutes and causes no meaningful disruption, the overhead of a preventive maintenance programme may not be justified.

When Reactive Maintenance Becomes a Liability

The problem arises when reactive maintenance is applied by default - not by design.  

Across Australian and New Zealand facilities, unplanned downtime is consistently cited as one of the top cost drivers for maintenance teams. On average, eams with a high ratio of reactive to planned maintenance spend significantly more per work order and experience longer mean-time-to-repair.

Reactive maintenance becomes a genuine risk when:

• Critical infrastructure is involved. HVAC systems, fire suppression equipment, lifts, and electrical switchboards are not candidates for run-to-failure. The consequences of failure - for safety, compliance, and business continuity - are too severe.

• Secondary damage occurs. A failed bearing that goes unaddressed can destroy a motor housing. A minor roof leak left until it becomes visible inside a building can cause tens of thousands of dollars in damage. Reactive approaches can turn small faults into large ones.

• Labour and parts costs spike. Emergency call-outs, after-hours technician rates, and urgent parts procurement drive up costs substantially compared to planned maintenance.  

• Asset life is shortened. Running assets to failure consistently degrades components faster, reducing overall lifespan and increasing capital replacement costs.

• Occupant or tenant experience suffers. In commercial property, healthcare, education, and hospitality environments, reactive failures are visible failures. They damage trust and reputation.

The Hidden Cost of a Reactive-Centred Maintenance Culture

Many organisations fall into reactive maintenance not as a strategy, but as a symptom. When maintenance teams are under-resourced, understaffed, or working without clear visibility of their asset portfolio, they spend most of their time firefighting rather than planning. This is sometimes called the "reactive maintenance trap."

Facility teams caught in this trap often find it difficult to break the cycle - reactive work generates urgent work orders, which consume the time that would otherwise be used for preventive planning, which generates more reactive failures.

Breaking this cycle requires two things: a deliberate maintenance strategy that categorises assets by criticality, and the systems to support that strategy with accurate data, timely work orders, and performance tracking.

How to Decide: A Simple Decision Framework

Use this asset-level decision framework to determine whether reactive maintenance is appropriate:

Could failure cause a safety incident?  

• Yes: Avoid reactive maintenance  

• No: Continue assessment  

Could failure disrupt critical operations?  

• Yes: Avoid reactive maintenance  

• No: Continue assessment  

Is the asset easily and cheaply replaced?  

• Yes: Reactive maintenance may be appropriate  

• No: Consider preventive maintenance  

Is a redundant system in place?  

• Yes: Reactive maintenance may be appropriate  

• No: Consider preventive maintenance  

Does prevention cost more than failure?  

• Yes: Reactive maintenance may be appropriate  

• No: Consider preventive maintenance

Assets that pass all five questions without triggering a "avoid" response are reasonable candidates for run-to-failure. Everything else warrants a more proactive approach.

The Role of FM Software in Managing Reactive Work

Even when reactive maintenance is intentional and appropriate, it still needs to be managed well. Poorly tracked reactive work leads to missed patterns, repeated failures on the same asset, and no accountability for response times or repair costs.

Purpose-built facilities management software gives maintenance teams the ability to log reactive work orders as they arise, track response and resolution times, record parts and labour costs against specific assets, and analyse failure trends over time. That data becomes the foundation for smarter decisions - including recognising when a repeatedly failing asset should be moved from a reactive to a preventive maintenance strategy.

Key Takeaways for Facility Teams

• Reactive maintenance is a legitimate strategy for non-critical, low-risk, easily replaced assets

• It becomes a liability when applied to critical systems, or when it is the default rather than a deliberate choice

• The true cost of reactive maintenance includes emergency labour rates, secondary damage, shortened asset life, and operational disruption

• A simple criticality-based decision framework can help teams allocate the right maintenance strategy to the right assets

• FM software is essential for tracking and analysing reactive work, even when it is intentional
