How to Properly Train to Troubleshoot Mini-Split/Ductless System Basics  

These days, mini-split air conditioning systems are becoming increasingly popular in both residential and commercial applications. These systems allow for precise temperature control on a room by room basis with limited or elimination of ductwork altogether. Getting back to basics and understanding block and room by room loads should be communicated. Knowing the application and the equipment capabilities should be at an all-time high. With more and more people turning to these mini-split systems to keep their homes comfortable, there is also a greater need for HVAC technicians who understand the intricacies of these systems and how to troubleshoot common problems.

Lack of Training on Mini-Split Systems: A Serious Problem

Unfortunately, there is a serious lack of enthusiasm for training across the HVAC industry when it comes to mini-split air conditioning systems. These systems use a lot of unique and sophisticated technology that can pose troubleshooting challenges for HVAC technicians who aren’t highly knowledgeable in their operation.

Most HVAC technicians receive extensive training on “traditional” air conditioning systems, such as central air units, because these are the most commonly utilized in the field. However, knowledge of these traditional systems cannot be easily applied to mini-split units; the differences are too substantial. As a result, HVAC technicians may make mistakes in installing a mini-split system or may be unable to effectively diagnose and repair a problem.

Understanding Differences Between Traditional AC and Mini-Split Systems

It’s important for HVAC professionals to understand that mini-split systems operate differently than a traditional air conditioning unit. Not only do these units operate with limited ductwork or with none at all, but they operate much like that of a computer with embedded software algorithms communicating with real-time conditions. Maintenance, however, is actually less invasive because these systems use software logic with thermistors that are constantly monitoring real-time conditions. Therefore, preventative maintenance should not be overlooked.

Common Issues Unique to Mini-Split Systems

An overall lack of training on mini-split systems can make common issues difficult for HVAC technicians to diagnose and repair. There are many common issues that can be easily overlooked by an untrained eye, including:

  • Application
  • Installation
  • Maintenance

The Importance of Training Your Staff to Avoid Mishandling in the Field

With so many residential and commercial HVAC clients turning to mini-split systems for their air conditioning needs, there is a greater demand than ever for HVAC technicians who are well versed in these unique and complex cooling systems. If your HVAC team hasn’t received specific training on these systems and how they work (as well as how to diagnose and perform common repairs), you could be missing out on business. Even worse, you could be putting the reputation of your own business at risk if any unknown application or installation steps are made. As the saying goes, “we don’t know what we don’t know.”

Taking the time to ensure that your employees are properly trained can help your HVAC staff enjoy greater confidence on calls related to mini-split systems and will help to avoid unknown mistakes in the field. Consider researching local training options to provide your HVAC team with the resources they need to master this system; this type of training will be money well spent.
