Aircon 53 www.aftermarketonline.net JUNE 2026 dilute can lead to compressor failure due to lack of lubrication. So, without knowing if the system already has UV-dye, the technician doesn’t know whether to override this function or not. Each of the service steps highlighted previously is crucial in ensuring the overall health of the AC system, and each must be undertaken proficiently to guarantee the right outcome. Examples include only using the low pressure side of the loop to recover refrigerant, to check for damage or corrosion throughout the system, to use the most appropriate method for leak testing, to use both the low and high pressure connections to evacuate the system, to understand which ports to use when charging the system, and then to carry out a thorough performance test of the system after the service is completed. The opportunities Although the examples highlighted emphasise the complexities of the AC system, it is also a fact that, in contrast to some vehicle technologies that are coming to the end of their development, and in some cases even their lifecycle, the AC system will be ever-present, irrespective of the powertrain and vehicle design. Therefore, overlooking the ongoing profit opportunities associated with an AC specialism would seem somewhat foolhardy. Necessary training As is apparent, AC service and repair cannot be undertaken lightly; it requires specific training to equip technicians with the knowledge and skills needed to tackle these important vehicle systems with confidence and ensure they complete the work thoroughly and successfully. As an original equipment manufacturer and AC system supplier to vehicle manufacturers across the globe, DENSO is ideally placed to provide the required training, as well as having the ability to supply the premium quality replacement parts needed to complete the process. DENSO’s training programmes can be conducted face-to-face and initiated via the company’s trusted distributors in all markets throughout Europe, and are also supplemented by comprehensive online resources through its e-Learning portal. These online tutorials address subjects such as the Basics of AC, Oil Contamination, Common Compressor Failures, as well as the Seven Basic Steps of AC Service, which brings us neatly back to the beginning and the necessity to upskill the workforce, to enable independent workshops to address the existing and ongoing demand for AC service and repair. www.denso-technic.com
