Car AC (Automotive Air-Conditioning) Leak Testing, Vacuuming, Gas Charging & Performance Testing

Course Overview

The aim of these qualifications is to provide the learner with the knowledge and skills to work on the Automotive Air Conditioning courses introduce the principles of automotive air conditioning systems, including refrigerant theory, and provide students with hands-on experience with air conditioning equipment also covers the required underpinning knowledge and practical skills.

The course is designed to upskill the engineering technicians working within their trade discipline or appreciating another, where knowledge and understanding may be required.

The candidate should have basic knowledge of Air Conditioning.

Upon completing the training course, candidates will be awarded a ‘Certificate of Attendance’ from NTI, attested by the Ministry of Manpower.
