The Importance of Preventive Maintenance

HVAC equipment is constantly improving and evolving, but the key to durability and performance of a HVAC system is proper maintenance. Preventive maintenance of your customer’s HVAC systems is the cornerstone of a well-operating unit. As all industry professionals agree, timely maintenance on a regular basis is the only way to make the most out of a unit. Neglect can lead to shorter life, higher utility costs, and severe malfunctions which can require a lot of money to adequately repair.

This is where you and your technicians come in to explain the importance of proper HVAC preventive maintenance. Regularly maintaining your customers’ units will not only prevent more serious malfunctions from occurring, but it will also provide other important benefits. Let’s take a look at what preventative maintenance actually is, and what advantages it offers.

What Is HVAC Preventive Maintenance?

HVAC preventive maintenance is a combination of different service checks of all components of the heating and cooling systems with the aim of confirming proper operation. Some of the service checks performed during PPM, or planned preventive maintenance are:

  • Detailed analysis of several operating parameters, such as vibration and noise
  • In-depth examination of different components critical for efficient operation
  • Verification of whether or not the system is operating at optimal capacity
  • Inspection of the proscribed health and safety measures

It’s also important to note that all preventive maintenance has to be performed by certified service engineers wearing adequate protective equipment per latest safety standards. They also have to undergo certain training before being granted official ability to perform PPM.

What Are The Benefits Of HVAC Preventive Maintenance?

Preventive maintenance is not only important for ensuring your customer’s heating and air conditioning systems are operating adequately. There are also other benefits to regular PPM that your clients can reap if they decide to create a preventive maintenance schedule:

Better Reliability

Preventive maintenance ensures that the parts and components of your customer’s heating and air conditioning system are in good condition, or it preemptively identifies parts in need of repair, preventing serious breakdowns from occurring. This ensures your customer’s HVAC system has maximum uptime while operating at peak performance to provide cool and clean air.


PPM is necessary to ensure your customer’s HVAC system complies with all of the proscribed legal, as well as health and safety requirements. This sort of compliance is also a requirement of different auditory bodies, such as the EPA or the HSA. Your customers have to make sure their heating and cooling systems are up to code.

Increased Energy Efficiency

Finally, planned preventative maintenance vastly improves the overall system efficiency by ensuring harmonious operations of the many different components of an HVAC system. A system that is well-balanced will not only provide optimal energy efficiency, but it will also offer the highest possible level of comfort and convenience control.

What Are The Downsides Of Lack Of Preventive Maintenance?

On the other hand, if your customers choose not to perform regular preventive maintenance of their heating and cooling systems, they will not only miss out on reaping the numerous benefits, but they can also expect to suffer certain downsides:


HVAC systems directly feed into your customer’s business or production operation supply chain, which means that if the heating and cooling system fails the entire operation will incur unnecessary downtime to perform repairs. This costs your customers money and can seriously damage their brand reputation.

Poor Conditions

Without PPM, your customers risk more frequent breakdowns, which will not only lead to uncomfortable working conditions for their employees, but also to employee dissatisfaction and inability to perform their jobs at a high level. Being too hot or too cold can seriously hamper employee performance and happiness.

Failures Regarding Health & Safety

If your customer’s business suffers an auditory failure, they risk incurring serious fines and unnecessary closures. Also, they could be putting their staff at risk by failing to comply with the necessary health and safety standards, which could lead to workplace injuries.
