Compare The Difference Between Preventive And Breakdown Maintenance

Just like murder, preventive maintenance is premeditated - you plan to clean and service your customer’s assets to avoid breakdowns. Breakdown Maintenance however is based on the physical breakdown of an asset before scheduling the maintenance. To break apart the different types of maintenance, we discuss the top 4 differences between them and the main factors to consider for your HVAC business.

What is Preventive Maintenance?

Preventive maintenance is all about regularly scheduled maintenance work that is based on a contract or service agreement. Preventive maintenance aims to make regular contact with an asset to avoid defects and keep performance levels stable. This style of maintenance has a key focus in minimising defects and reducing unplanned equipment downtime.

A preventive maintenance structure will follow the basics of:

  1. Begin maintenance contract with customer
  2. Decide on schedule and maintenance consistency (3 monthly, 6 monthly, annually)
  3. Complete scheduled maintenance of assets and reports
  4. Keep assets performing with no unplanned downtime

Examples of preventative maintenance include the scheduled servicing of a water heater, refrigeration units of any size of use (residential, commercial or industrial). Maintenance for an annual schedule would consist of inspecting pressure valves, replacing the anode rod and flushing the system to ensure minimal downtime and failures for your client’s assets.

With tools such as a HVAC maintenance checklist, you can manage your maintenance schedule and system to reap the maximum benefits for your business.

What is Emergency Maintenance?

Emergency maintenance (also known as breakdown maintenance or corrective maintenance) focuses on fixing a defect after it occurs. Breakdown maintenance isn’t planned in advance of a defect but will occur after unplanned downtime. Similarly to predictive maintenance, an emergency maintenance program will also be triggered by the condition of the asset.

An emergency/breakdown maintenance structure will look something along the lines of:

  1. Asset breakdown
  2. Client calls technician to site
  3. Detect and analyse to find fault
  4. Fix asset

This example of maintenance can include simple maintenance like changing light bulbs. Changing light bulbs is one example of maintenance that doesn't require preventive actions, but gets the most benefit from a breakdown maintenance plan.

 

Top 4 Differences Between Preventive And Breakdown Maintenance

To decide what maintenance plan works best for you, weighing the facts and differences between preventive vs breakdown maintenance can help you determine what your business needs.

 

1. Systems

When looking at the systems in place for both preventive and upkeep maintenance management, they vary based on their triggers. While a preventive maintenance strategy will focus on a set scheduled contract, a breakdown maintenance program will base their work from the performance of an asset.

A preventive maintenance program will need an asset maintenance system in place to work effectively and schedule your maintenance work. Preventive maintenance will focus on:

  1. Building an Asset Register
  2. Maintenance Contract Management
  3. Building Maintenance Tests
  4. Maintenance Scheduling of assets and Tests
  5. Asset Maintenance Testing in the Field
  6. Asset Maintenance Test Reports
  7. Follow Defect Quote workflow
  8. Monthly Billing

While breakdown maintenance tasks will focus on:

  1. Scheduling Just in Time
  2. Trained Technicians that can troubleshoot
  3. Purchase Order workflow on the run
  4. Service Reports
  5. Timesheets
  6. Do & Charge billing

2. Service Level Agreements (SLAS)

Maintenance requirements in the HVAC industry such as SLA's can also be a varying factor in equipment failure and maintenance tasks. Determining what types of assets your clients have will affect the way you program your maintenance.

Preventive maintenance with fixed intervals will reduce the chance of voiding warranty or contracts through regular maintenance where asset performance can be monitored.

Breakdowns however can void warranty due to equipment failures as a result of no maintenance. When considering what maintenance management is right for your business, this is an important consideration.

Fire asset management has variable intervals and can have maintenance tolerances similar to this.

3. Responsiveness

Breakdowns and equipment failure are important issues in any HVAC business and by having great operations in place to timely meet SLAS, you can improve your responsiveness. When you have a great response time and can provide a fast and responsive service you will build good will and generate more work.

Preventative maintenance will help reduce your workload in the more busy periods by moving your maintenance tasks to the quieter months. This frees up more time in the peak seasons (summer and winter) where you will typically have more equipment breakdowns and hence a higher response rate.

Emergency maintenance teams on the other hand, may find themselves inundated with work orders during peak seasons and their response time can sometimes suffer because of this.

4. Predictability

Preventive maintenance allows you to generate a predictable income and generate low cost additional work.

A breakdown maintenance service life will typically generate less predictability in your workflow as you are relying on equipment failure before you gain any work. In this type of maintenance, you will find the maintenance costs can be more unpredictable than a preventive method.
