Preventive maintenance (PM) is a facility manager’s best friend—and it’s good for any company’s bottom line. Just like regular tune-ups and oil changes for your car, proactive maintenance, or preventive maintenance, goes a long way toward preventing a critical equipment failure that can leave your operations stranded on the side of the road while you wait for someone to come fix what’s wrong.
Different types of operations require different types of preventive maintenance plans—but they all require careful planning. Building the right program for your facility depends on understanding what the preventive maintenance process entails, the different types of preventive maintenance, and what to consider when implementing an effective preventative maintenance strategy.
Key Takeaways:
- Preventive maintenance services equipment on a planned basis before it fails, which costs less over time than repairing breakdowns.
- The main types are time-based, usage-based, condition-based, predictive, reliability-centered, and planned maintenance. The right mix depends on your equipment, each asset’s criticality, and your team’s resources.
- A preventive maintenance checklist should cover each asset’s recurring tasks, how often they’re done, what a pass looks like, the tools, parts, and safety steps needed, and where you record results.
- Organize the checklist by building system and frequency, then customize it for each site’s equipment, type, and climate.
- Every program needs an asset inventory, clear priorities, a schedule, inspections, records, and regular review. Software makes that easier to run across many locations.
What is Preventive Maintenance?
Preventive maintenance is a method for keeping all of your assets in good working order to prevent equipment failures and unplanned downtime. It involves proactively scheduling maintenance tasks like inspecting equipment for potential issues before they become significant problems for your maintenance operations. Preventive maintenance examples include cleaning and lubricating the moving parts of equipment and replacing parts that are wearing out—before they wear out. Regular maintenance helps extend the life of your assets and reduce the costs associated with unplanned maintenance and repairing and replacing equipment.
Preventive Maintenance vs. Reactive Maintenance
The opposite of implementing a preventive maintenance schedule is performing reactive maintenance, or corrective maintenance, which is just what it sounds like—servicing your assets only in reaction to their various failure modes. Reactive maintenance costs far more in the long-term than a solid, comprehensive preventive maintenance strategy.
Advantages of Preventive Maintenance Schedules
The benefits of regular preventive maintenance vs. reactive maintenance extend beyond protecting your assets against premature failure and unplanned equipment downtime.
- Equipment that undergoes regular maintenance works better, whether it’s your HVAC system keeping customers cool, the ovens in your bakery maintaining the perfect temperature, or the coolers in your convenience store keeping beverages ice-cold.
- Equipment that’s in great condition has a higher resale value when it’s time to upgrade.
- Properly maintained equipment uses less energy and emits fewer greenhouse gasses than equipment that’s not part of a preventive maintenance strategy.
- Regular inspections help improve the safety of your equipment—and your maintenance teams.
Preventive Maintenance Examples
The tasks involved in preventive maintenance depend on the equipment. A preventive maintenance checklist for electrical systems might involve routine maintenance tasks like inspecting electrical panels and wiring, checking grounding and surge protection systems, and replacing damaged cords. A preventive maintenance task checklist for an HVAC system includes activities like lubricating moving parts, replacing filters or belts, cleaning coils, and checking for gas or refrigerant leaks. Scheduling preventive maintenance services on a regular basis helps you identify and address issues before they cause unplanned breakdowns and high corrective maintenance costs.
What Should Be Included in a Preventive Maintenance Checklist?
A preventive maintenance checklist should list every recurring task for each asset, how often it’s done, and what a passing result looks like. Each item should also include the required tools and parts, the safety steps to take first (such as lockout/tagout), and a place to record the result and any follow-up work order.
A checklist turns a preventive program into routine work done the same way at every site.
What Each Checklist Item Needs
- Asset and location: The specific unit, not just the system, so results build a history for that asset.
- Task: One action with an observable result. A technician new to the site should be able to complete it without asking.
- Frequency or trigger: A calendar interval, runtime hours, or a season.
- Pass criteria: The reading, range, or condition that counts as acceptable.
- Tools, parts, and PPE: List them up front so the technician arrives with everything.
- Safety steps: Lockout/tagout, permits, or site notifications that come before the work. OSHA estimates that compliance with its lockout/tagout standard prevents about 120 deaths and 50,000 injuries a year.
- Time estimate: So the work can be scheduled and staffed realistically.
- Result and follow-up: Where the technician records the outcome and what happens if an item fails.
Most items fall into one of two kinds. Quick pass/fail checks compare a reading or condition against a standard, which is how most preventive maintenance inspections work. Step-by-step procedures cover a full job, such as replacing a belt or servicing a water heater, in the required order.
Preventive Maintenance Checklist by System and Frequency
These are typical starting intervals for commercial facilities. Adjust them for the manufacturer’s guidance, local codes, climate, and how hard each site uses its equipment. Small, frequent tasks matter. For example, the U.S. Department of Energy says replacing a dirty, clogged filter with a clean one can cut an air conditioner’s energy use by 5% to 15%.
| System | Daily or weekly | Monthly | Quarterly | Annually |
|---|---|---|---|---|
| HVAC | Check thermostat settings and schedules; note unusual noise or odors at startup | Replace or clean filters (more often at dusty or high-traffic sites); check condensate drains | Inspect belts and pulleys; clean condenser and evaporator coils | Full service before cooling season and before heating season; check refrigerant charge and electrical connections |
| Refrigeration | Log case and walk-in temperatures; check that doors and gaskets seal | Clean condenser coils on self-contained units; check defrost cycles | Inspect evaporator fans and drain lines | Full system service by a licensed refrigeration technician |
| Electrical and lighting | Replace failed lamps; confirm exit signs are lit | Test emergency lights for 30 seconds | Inspect panels for heat, odor, or damage; check exterior lighting timers and photocells | Run the 90-minute emergency lighting test; thermal scan of main panels and switchgear |
| Plumbing | Check restrooms for leaks and running fixtures | Check water heaters for leaks; test sump pumps; clear floor drains | Check grease interceptor levels at food service sites | Flush water heaters; test backflow preventers where local code requires |
| Fire and life safety | Keep exits, extinguishers, and sprinkler heads clear | Inspect extinguishers (gauge, seal, access) | Inspect sprinkler valves and alarm devices, or as local fire code requires | Extinguisher maintenance and sprinkler and alarm testing by a licensed contractor; kitchen hood suppression service twice a year |
| Roof and building envelope | Note leaks, ceiling stains, or damage after storms | Clear roof drains and gutters (more often in fall) | Inspect exterior sealants around windows and doors | Roof inspection in spring and fall, and after major storms |
| Doors and entrances | Confirm automatic doors open and close fully; check locks | Lubricate hinges, closers, and dock levelers | Inspect overhead doors, dock seals, and weatherstripping | Automatic door inspection by a certified inspector |
How to Customize the Checklist for Each Site
- Start with each site’s asset inventory: List only the equipment the site actually has, and add model-specific steps from the manufacturer’s manual.
- Adjust for the type of site: Food service adds hoods, fryers, and grease management, as in this restaurant preventive maintenance checklist. Stores put more weight on storefronts, lighting, and seasonal prep, as in this year-round retail store maintenance checklist.
- Adjust for climate and use: Sites in hot, humid, or dusty areas, or with long operating hours, usually need shorter intervals for filters, coils, and roof drains.
- Keep the task order the same everywhere: Safety steps first, then cleaning, inspection, and adjustment, then parts replacement, with a final test and a recorded result.
- Assign an owner to every item: Decide which tasks in-house staff handle, which go to service providers, and who reviews completed checklists.
- Review the checklist on set triggers: Revisit it when you add or replace equipment, when an asset keeps failing soon after service, and at least once a year.
Once the checklist is set, turn it into a calendar with a preventive maintenance scheduling template. ServiceChannel helps multi-site teams schedule preventive maintenance, assign it to service providers or in-house technicians, and track completion.
Types of Preventive Maintenance Strategies
The type of preventive maintenance plan that’s best for your company depends on the types of equipment you use, the criticality of your different assets, and the resources available to your maintenance team. Here are some common types of preventative maintenance schedules you can choose from.
Time based preventive maintenance (TPM)
Time based preventive maintenance involves performing routine maintenance tasks at predetermined intervals. Time based preventive maintenance schedules might be monthly, quarterly, or annually—or it could depend on the type of asset, the industry standards, the manufacturers’ recommendations, and how critical the equipment is to operations. A time based approach to preventive maintenance assumes that the equipment in question will need some type of preventive maintenance task at regular intervals, regardless of usage.
Reliability-centered maintenance (RCM)
Reliability-centered maintenance originated in the aviation industry and is widely employed in manufacturing, transportation, and energy. The key principle of RCM is that there is no one-size-fits-all maintenance plan that’s ideal for all asset types. RCM identifies the most relevant and effective maintenance strategy for an asset based on its particular needs, criticality, and failure consequences. The aim of RCM is to perform preventive maintenance in a way that maximizes the reliability and safety of equipment.
Usage-based maintenance
Usage-based preventive maintenance—also known as meter-based preventive maintenance—is a strategy of performing maintenance tasks based on the actual usage of an asset, such as hours, mileage, or cycles of operation. A usage-based preventive maintenance workflow is ideal for assets that have various usage patterns, like vehicles, conveyor systems, or pumps. It ensures the maintenance tasks are aligned with the actual use of the equipment and scheduled based on the wear and tear you’d expect at various usage points.
Condition-based maintenance (CBM)
Condition-based maintenance involves monitoring the condition of assets using sensors, data analysis, and predictive techniques. By continuously monitoring equipment performance and analyzing data, you can identify early warning signs of potential failures. CBM allows for targeted and preventative maintenance interventions, reduces unnecessary maintenance, and maximizes asset availability.
Predictive maintenance
Predictive maintenance leverages advanced analytics and machine learning algorithms to monitor equipment and predict failures. It optimizes maintenance activities and reduces unnecessary maintenance tasks by using real-time data, historical records, and predictive maintenance models to determine the best preventive maintenance schedule for a particular piece of equipment. Predictive maintenance is ideal for critical assets and can result in far fewer costly repairs.
Planned maintenance
Planned maintenance, also known as scheduled maintenance, is a proactive maintenance strategy that involves scheduling maintenance activities during planned downtime or during periods of low production demand. By coordinating preventive maintenance tasks with production schedules, you can minimize disruptions and maximize your maintenance resources. Planned maintenance is particularly beneficial for facilities with time-sensitive operations or limited downtime windows.
Elements of a Preventive Maintenance Program
A good preventive maintenance plan is based on factors like the amount and types of equipment you have, the criticality of your different asset types, and the size of your maintenance team. Regardless of the type of preventive maintenance schedule you implement, whether it’s predictive maintenance or a time-based plan, it should include these essential elements.
Asset inventory
Keeping an up-to-date inventory of all of your equipment helps you identify and prioritize assets for preventive maintenance, track their history, and ensure that no critical equipment components are overlooked.
Asset prioritization
Assigning priority levels to assets based on their criticality and impact on operations allows you to allocate resources effectively. Critical assets may require more frequent inspections and more comprehensive preventive maintenance activities than equipment that’s not as critical.
Maintenance scheduling
A well-planned maintenance schedule ensures that periodic maintenance is carried out systematically and in a timely manner. Preventive maintenance scheduling helps you avoid disruptions, streamline resource allocation, and optimize the availability of your assets.
Regular inspections
Regular inspections help you identify signs of wear, damage, or potential issues early on. These inspections can be conducted visually in person or with the help of sensors and monitoring systems, depending on the asset type, complexity, and the proactive maintenance plan you have in place.
Lubrication and cleaning
Proper lubrication and cleaning are essential preventive maintenance tasks for HVAC and other systems that help reduce friction, corrosion, and buildup of grime, which all contribute to premature equipment failure. These activities help keep your critical equipment running smoothly and efficiently to prevent unplanned downtime.
Documentation and record-keeping
Maintaining complete and accurate documentation of all preventive maintenance activities helps you track the maintenance cost and preventive maintenance benefits of each piece of equipment, identify recurring problems, and ensure compliance with warranty requirements. It also helps you track and plan your maintenance procedures and decide when and how often to schedule maintenance.
Performance measurement
Measuring the performance of assets allows facility managers to assess how effective your preventive maintenance program is. By monitoring key performance indicators (KPIs), such as equipment downtime during unplanned maintenance, mean time between equipment failures, and maintenance costs, you can identify areas for improvement and optimize your preventive maintenance strategies.
Continuous improvement
Regularly reviewing and improving your preventive maintenance plan is important for getting the most out of your proactive maintenance strategy. Analyze data, solicit feedback from your maintenance teams, and stay updated on industry best practices to continuously improve your preventive maintenance workflow and optimize your preventative maintenance program’s effectiveness.

Frequently Asked Questions
At least once a year, and any time equipment is added or replaced, a code requirement changes, or the same asset keeps failing soon after service. Technician feedback is a good early signal: if steps are routinely skipped or don’t match the equipment on site, the checklist needs work.
The checklist covers what to do on each visit and what counts as a pass. The schedule covers when each visit happens and who does it. You need both: a schedule without a checklist leads to inconsistent work, and a checklist without a schedule often goes unused.
Start with life-safety equipment and assets whose failure would close a site, spoil product, or cause expensive emergency repairs, such as HVAC, refrigeration, and electrical systems. Add lower-impact equipment once those tasks are running reliably.
The technician records the result and reading and creates a corrective work order so the repair is tracked to completion. Escalate safety-related failures right away. If the same item fails repeatedly, review the task, its frequency, or the asset itself.
