Preventive Maintenance: Benefits, Types & How to Implement It

Preventive maintenance is the practice of regularly inspecting, servicing and maintaining equipment to prevent unexpected breakdowns and extend asset life.

Instead of waiting for equipment to fail and reacting to it, maintenance teams perform scheduled inspections, lubrication, filter replacements and other service tasks before problems occur. The goal is simple: Catch small issues early, so they never become expensive failures.

After all, maintenance teams dread surprise breakdowns — yet we still see them every week. One missed inspection can trigger tenant complaints, service interruptions or five-figure repair invoices. A failed HVAC system, for example, can easily cost $15,000 or more to repair and create major operational disruption.

Preventive maintenance (PM) flips that script. By scheduling routine maintenance tasks in advance, organizations reduce downtime, control repair costs and keep equipment operating reliably. Instead of scrambling to respond to emergencies, teams operate with predictable maintenance schedules and better visibility into asset health.

Preventive Maintenance, Explained

Preventive maintenance (PM) is about being proactive, which is undeniably critical to any maintenance strategy. It’s key to lowering maintenance costs, reducing unplanned downtime, improving asset lifespan and efficiency, and increasing workplace safety. In fact, some manufacturers report 52.7 percent less unplanned downtime as a result of using PM strategies.

Any type of maintenance that is not reactive (i.e., a response to a problem) is preventive, and there are many different types of preventive maintenance that relate to different industries or specific timing. Preventive maintenance also sits within the broader category of planned maintenance, which refers to any maintenance work scheduled ahead of time to reduce equipment failure risk. Planned maintenance strategies include preventive maintenance, predictive maintenance, condition-based maintenance and other proactive approaches designed to improve reliability.

In practice, preventive maintenance works best when it’s intentional. Teams that try to “PM everything” often burn out. The most effective programs focus on assets where failure would cause downtime, safety risk or customer disruption — while lower-risk assets may receive lighter oversight or even run-to-failure strategies.

Ready to move from reactive firefighting to proactive reliability? This guide shows you how to build a preventive maintenance strategy — step by step with checklists and examples — to cut emergency repairs and keep your operation running smoothly.

Looking for preventive maintenance checklists? Here are two — an industrial preventive maintenance checklist and a facilities preventive maintenance checklist — that you can download.

Types of Preventive Maintenance

Time-based maintenance, usage-based maintenance, condition-based maintenance, predictive maintenance and prescriptive maintenance are all different types of preventive maintenance. We also include risk-based maintenance, which many organizations now treat as a critical planning layer for preventive maintenance.

Here’s each type works:

Time-Based Maintenance

Time-based maintenance, also known as interval-based maintenance, is a maintenance strategy in which maintenance tasks are scheduled based on predetermined time intervals. In this approach, critical equipment or machinery undergo maintenance activities at regular intervals regardless of the asset’s usage or condition. We see time-based maintenance work best for regulated systems like HVAC, fire safety and food equipment — where compliance matters as much as uptime.

PM tasks are performed regularly to minimize the risk of unexpected failure modes, maintain equipment reliability and increase uptime. Create a monthly or annual equipment maintenance schedule that follows manufacturer recommendations for inspecting and cleaning equipment to keep you on track.

Usage-Based Maintenance

Usage-based maintenance is when maintenance tasks are carried out based on equipment usage. Whether it’s a vehicle oil change or an essential piece of machinery that reaches a certain number of hours, staying on top of proper maintenance ensures long-lasting use and extends the asset lifecycle of important equipment. Note: Usage-based triggers are especially effective for fleets and production equipment where wear correlates directly with runtime.

Condition-Based Maintenance

Condition-based maintenance (CBM) involves condition monitoring of your most crucial assets to identify maintenance needs. It relies on sensors (i.e., temperature or sensors) that capture real-time information about equipment to detect anomalies.

For example, an infrared sensor could gather extreme temperature data from far away, showing that a piece of manufacturing equipment is operating above its standard temperature. This maintenance approach is different in that it’s not on a set schedule but more based on the condition metrics for a piece of equipment. Without consistent data and follow-through, though, condition alerts often get ignored — turning CBM into noise instead of insight.

Predictive Maintenance

Predictive maintenance (PdM) goes a step further. It combines condition monitoring with machine learning to predict a system crash before it happens. This allows you to perform maintenance only when your machinery actually needs it.

In our experience, predictive analytics delivers the biggest ROI in environments where downtime is measurable and teams actually act on the alerts. In fact, a report from McKinsey & Company found that predictive maintenance strategies can result in an 18 to 25 percent costs savings. That’s especially true for manufacturing and energy industries that require industrial preventive maintenance for more complex equipment.

Prescriptive Maintenance

Taking it yet another step further than PdM, prescriptive maintenance uses advanced predictive analytics, machine learning and artificial intelligence to generate predictions about maintenance and to act on them. Prescriptive maintenance doesn’t just flag risk — it recommends what to do, when to do it and sometimes automatically initiates the response by creating a work order and assigning it.

For example, imagine a vibration sensor on a critical air handler detects a pattern consistent with bearing wear. The AI model doesn’t just predict “failure likely in 21 days.” It checks parts inventory, confirms that a replacement bearing is in stock, reviews technician availability and automatically creates a scheduled work order. It even attaches the correct procedure and safety checklist.

Sound advanced? That’s because it probably is. For most teams, disciplined manual PM beats advanced AI tools that no one has time to manage.

Risk-Based Maintenance

Risk-based maintenance (RBM) prioritizes preventive maintenance tasks based on asset criticality and failure risk. Instead of servicing every asset on the same schedule, RBM evaluates:

• Probability of failure
• Operational impact of failure
• Safety or regulatory risk
• Cost of downtime

Assets with the highest operational risk receive the most preventive attention, while lower-risk assets may receive lighter maintenance or even run-to-failure strategies. This approach helps maintenance teams allocate limited resources where they produce the most reliability value.

Reactive Maintenance & Run-To-Failure Strategies

Of course, the goal of preventive maintenance is to move from a reactive maintenance strategy, which involves repairing equipment only after it fails. One common form of reactive maintenance is run-to-failure maintenance, in which organizations intentionally allow equipment to operate until it breaks before replacing or repairing it.

Run-to-failure can be appropriate when:

• Equipment is inexpensive to replace (like a light bulb)
• Downtime has minimal operational impact
• Preventive maintenance costs more than replacement

However, over-reliance on reactive maintenance often leads to:

• Emergency labor costs
• Unplanned downtime
• Production losses
• Higher long-term repair costs

Most modern maintenance strategies combine preventive maintenance for critical assets with limited run-to-failure strategies for low-risk equipment.

7 Essential Elements of a Preventive Maintenance Program

An effective preventive maintenance plan typically relies on a robust maintenance framework that comprises the following seven core elements:

1. Testing: Equipment should be regularly tested and evaluated to ensure it’s meeting performance benchmarks and to identify potential failure modes before they result in equipment failure.
2. Servicing: Routine maintenance tasks, including oil changes and parts replacements, ensure proper equipment operation and improve asset longevity.
3. Calibration: Equipment settings should be regularly adjusted to meet specified operational standards and to ensure optimal performance and asset lifecycle.
4. Inspection: Regular examinations of the equipment, including internal parts that degrade over time, is critical to identifying wear and tear that could result in equipment failure.
5. Adjustment: As-needed adjustments to equipment may be required to maximize equipment reliability.
6. Alignment: Proper alignment of equipment components reduces wear and tear on spare parts, extending the lifespan of components and reducing the risk of breakdown.
7. Installation: Proper installation of new equipment is critical to ensure the asset is optimized for performance, calibrated to the manufacturer’s specifications and set up with a strong foundation for your future PM processes.

It’s important to note that, across the teams we work with, preventive maintenance fails less from lack of effort and more from inconsistency across these basics.

Benefits of Preventive Maintenance

One of the most obvious benefits of implementing a PM program is that you’re pre-empting issues before they occur. Here are some other benefits:

• Reduces downtime: Minimizing unexpected equipment failures helps reduce downtime by up to 50 percent as well as decreases the likelihood of business disruptions and closures by ensuring that machinery operates smoothly and reliably. 
• Increases asset’s lifespan: When you regularly service your machinery, you increase the equipment lifespan by up to 40 percent, which decreases expenses since you no longer need to replace equipment as often.
• Controls labor costs: Carrying out regular maintenance helps you better manage your maintenance backlog. It reduces the risk of after-hour breakdowns, meaning maintenance technicians will work only during scheduled hours, eliminating unexpected labor costs that come with emergency maintenance callouts.
• Eliminates potential safety risks: When you address issues proactively, you prevent them from escalating. This simple step eliminates potential safety risks.
• Improves spare parts inventory planning: Preventive maintenance creates predictable service intervals, allowing teams to plan spare parts inventory more efficiently. Instead of emergency purchasing, organizations can maintain optimized stock levels and reduce maintenance procurement costs.
• Supports sustainability goals: Well-maintained equipment consumes less energy, produces fewer emissions and lasts longer. Preventive maintenance reduces waste by extending asset lifecycles and minimizing premature equipment replacement.

This shift from reactive to preventive is where many Coast customers see the fastest operational gains. Case in point: Canton, Ohio-based Solmet Group started using Coast to help improve its preventive maintenance strategy. The result? The company now completes maintenance tasks five times faster.

“We’ve been able to optimize our maintenance scheduling and decrease downtime with this more comprehensive preventive maintenance strategy,” says Lisa Bosworth, the company’s manager of quality and continuous improvement. “Because the PMs are more in-depth now, we’re catching things before they’re happening.”

Disadvantages of Preventive Maintenance

You might be wondering: How could there possibly be a downside to staying prepared? But there are a few drawbacks to regular preventive maintenance, such as:

• Time-consuming: It can take a lot of time to carry out regular inspections across all your assets, especially if you have a lot of assets. It’s worth noting, however, that with a proper plan, you can space out your inspections and minimize the impact on your maintenance backlog.
• Costs more: Let’s face it, there’s more planning, preparation and upfront costs involved when you’re trying to make sure your assets do not run to failure.
• Overdoing it: Over-maintenance is one of the most common mistakes we see when teams first adopt preventive maintenance. It occurs when you excessively maintain your assets. Without asset criticality rankings or clear intervals, well-intentioned PMs can actually introduce failure instead of preventing it.

How to Avoid Too Much Preventive Maintenance

You can avoid over maintenance by creating a PM program. This program should include your preventive maintenance schedule that will ensure your planned maintenance is conducted at the right intervals, which will minimize the risk of over maintenance.

Always carefully consider whether a preventive action really needs to be performed. A good rule of thumb is: If you go past the optimum point of repairs and inspections on a particular piece of equipment, you’re doing too much preventive maintenance and wasting money. Only take PM actions when the benefits of doing so will outweigh the risks and costs.

How Much Does Preventive Maintenance Cost to Implement?

The cost boils down to labor costs and, ultimately, the number of machines and utilities you need improved or protected.

It’s important not to exceed your maintenance budget. Do what you can, where you can, to avoid future damages to your business caused by preventable accidents. This can be as simple and as budget-friendly as manually cleaning a ventilation system, increasing lubrication frequency on equipment or spending one hour training staff to operate certain machinery safely and effectively.

To determine how much of your budget should be allocated to proactive maintenance, your maintenance or facility management team should:

1. Add up the total cost of your reactive maintenance for the past year
2. Consider the value of all your equipment

This will give you a good idea of how much you can potentially save in the way of reactive maintenance, in addition to the savings you’ll enjoy from extending the life of your equipment. Most teams we work with start small — reallocating budget from emergency repairs into a handful of high-impact PM tasks — and expand once savings become visible.

How Preventive Maintenance Improves Overall Equipment Effectiveness (OEE)

Overall equipment effectiveness (OEE) is a common manufacturing and operations metric used to measure how efficiently equipment operates. OEE evaluates three factors:

1. Availability: Equipment uptime versus planned production time
2. Performance: Whether equipment operates at its intended speed
3. Quality: Percentage of defect-free output

Preventive maintenance improves OEE by:

• Increasing availability through reduced unplanned downtime
• Improving performance by keeping equipment calibrated and properly lubricated
• Maintaining quality by preventing mechanical degradation that causes defects

High-performing maintenance teams often see the biggest OEE gains by targeting PM activities on the assets that most affect production bottlenecks.

How to Implement an Effective Preventive Maintenance Plan

Ready to launch a preventive maintenance plan? Here’s a step-by-step guide to get started:

1. Define your maintenance goals.

Establish clear objectives to guide your initial strategy. For example, are you primarily focused on increasing machine uptime, extending equipment lifespans and/or lowering the overall asset maintenance costs? These maintenance goals will also dictate the types of KPIs that will be most valuable in assessing program success.

2. Prioritize which assets require preventive maintenance.

There’s a good chance that most, if not all of your assets, require some degree of preventive maintenance. But some assets may have more critical needs than others. This is where teams see the biggest payoff — focusing PMs on critical assets instead of spreading effort thin. Using a asset criticality assessment can help determine this. Here’s an example of how you might rate assets with a 1-5 rating system (with 5 being the most critical) in a manufacturing setting:

3. Create procedures and checklists to ensure consistency.

Detailed checklists improve team member accountability and ensure consistency across your PM program. If you use a computerized maintenance management system (CMMS), this platform can help you implement and enforce these procedures across all teams.

4. Train your maintenance team.

Equip maintenance staff with the knowledge and skills required to execute the program effectively. This may include training on the CMMS platform or an explanation of how your PM strategy is shifting away from reactive maintenance. You can also provide tutorials on new technologies used for communication or other day-to-day activities.

5. Create a PM schedule.

Develop schedules for all maintenance needs across all your assets. Consider using a CMMS to create and automate schedule creation and task reminders. This will significantly reduce downtime as well as the manual labor required to develop and maintain these PM schedules.

6. Use a CMMS for work order management.

A CMMS platform helps assign tasks, monitor progress, communicate with team members and analyze performance. This is the core of effective work order management.

7. Review your performance and optimize your program over time

By reviewing KPIs, you can refine your PM strategy for better results. After all, the most effective PM programs evolve quarterly, not annually.

Preventive Maintenance Examples

Across industries, preventive maintenance succeeds when it’s simple, repeatable and tied to business impact. Let’s briefly touch on a few specific PM examples:

• Check your HVAC system: If you’re a facility management company, and your A/C fails in summer, you’ll lose customers, negatively impacting your business. Routinely inspect your HVAC system (preferably seasonably) to avoid costly repairs in the event of future damage.
• Check critical assets: If you own a restaurant, a walk-in refrigerator is going to be one of your essential assets — your business can’t function without it. For regular refrigerator maintenance, it’s important to check door seals, defrost built-up ice, check the drip pan and drain hole, and clean the condenser coils every so often. Consider performing these tasks once per month when it comes to maintaining the optimum functionality of your most critical assets.
• Inspect all essential business vehicles: Be sure to have essential business vehicles inspected frequently. Failure to perform routine maintenance could result in breakdowns, engine failure and dangerous driving conditions. If possible, set up service reminders via an app, or check your mileage to stay on top of vehicle inspections. Basic vehicle preventive maintenance will ensure your fleet performs optimally for your business’ success.
• Complete property maintenance for communities: Running an apartment complex? Do routine inspections. This keeps tenants safe and preserves the property’s value. Water damage, for instance, can be detrimental to community living, but it’s easily preventable by making routine maintenance part of your workflow. Some examples of property maintenance services include regularly checking roofs and gutters, bathroom plumbing and appliances.

Preventive maintenance can be as complicated or as simple as you make it. It’s important to focus on only a handful of PM checklists at a time to keep the process manageable and cost-effective.

Key Metrics for Measuring Preventive Maintenance Success

Maintenance teams typically measure preventive maintenance performance using reliability metrics, such as:

• MTBF (Mean Time Between Failures): Average operating time between asset failures
• MTTR (Mean Time to Repair): Average time required to repair equipment after failure
• PM compliance rate: Percentage of scheduled preventive tasks completed on time
• Maintenance backlog: Total pending maintenance work orders

High-performing maintenance programs typically aim to increase MTBF while reducing MTTR — a combination that improves uptime and reliability.

Preventive Maintenance Software: Benefits & Features

The biggest shift teams experience with preventive maintenance software isn’t automation — it’s visibility. Historically, maintenance teams tracked PMs using pen and paper or spreadsheets. Both are very manual and time-consuming and don’t always lead to an accurate analysis. Preventive maintenance software (or maintenance planning software) provides a better solution by helping teams:

• Schedule PM tasks automatically
• Track maintenance history
• Monitor equipment performance
• Manage work orders

Technology adoption is accelerating as well. According to IBM research, 71 percent of executives say generative AI will significantly impact asset maintenance and reliability operations in the coming years. AI-enabled systems can analyze equipment data, predict failure patterns and automatically trigger maintenance workflows before breakdowns occur.
