About the Johnson Controls HVAC Apprenticeship

The successful candidate will join the HVAC Service Team and work alongside experienced technicians servicing mechanical HVAC systems at customer sites.

Rather than expecting an apprentice to independently diagnose and repair complex systems from the beginning, Johnson Controls will provide opportunities to develop technical capability through:

Structured training + mentoring + practical field experience.

This makes the position particularly relevant to someone who wants to start building a technical career in HVAC.

Minimum Requirements

Applicants should have:

• Matric certificate
• Strong interest in mechanical HVAC systems
• Interest in field-service work
• Ability to learn quickly
• Ability to follow technical instructions
• Commitment to safe working practices
• Valid driver’s licence
• Willingness to travel within Carletonville
• Good communication skills
• Teamwork skills
• Proactive work ethic

Previous exposure to HVAC, refrigeration or mechanical systems is advantageous but isn’t listed as compulsory.

No Previous HVAC Experience Required

This is one of the most important details for prospective applicants.

Johnson Controls states that previous exposure to:

• HVAC
• Refrigeration
• Mechanical systems

is an advantage but not required.

Candidates shouldn’t automatically disqualify themselves because they haven’t previously worked as HVAC technicians.

The position is specifically structured around learning from senior technicians and developing practical skills.

What Is HVAC?

HVAC stands for:

Heating, Ventilation and Air Conditioning.

HVAC systems are used to manage temperature, ventilation and environmental conditions within buildings and facilities.

Technicians working in this field may encounter a wide variety of mechanical and cooling equipment, depending on the site.

For this particular opportunity, Johnson Controls specifically mentions equipment such as:

• Chillers
• Package units
• Split systems
• Pumps
• Mechanical components

Working With Senior HVAC Technicians

Apprentices will work alongside experienced HVAC technicians during:

• Equipment inspections
• Service calls
• Preventative maintenance
• Troubleshooting
• Repairs
• Installation
• Testing
• Commissioning

This provides an opportunity to observe experienced technicians before progressively developing greater practical capability.

Preventative Maintenance

One area of development will involve preventative maintenance.

Rather than waiting for equipment to fail, preventative maintenance involves inspecting and maintaining systems to help reduce the likelihood of breakdowns.

The apprentice will assist senior technicians during these activities while learning appropriate maintenance procedures.

HVAC Troubleshooting

The apprentice will also support troubleshooting on equipment including:

Chillers, package units, split systems, pumps and other mechanical components.

Troubleshooting involves identifying why equipment isn’t performing correctly and helping determine what action is needed to restore reliable operation.

For someone who enjoys practical problem-solving, this can become an important part of developing as an HVAC technician.

Installation, Testing and Commissioning

The role isn’t limited to servicing existing equipment.

Apprentices may also assist with:

• HVAC equipment installation
• System testing
• Equipment commissioning
• Related mechanical systems

Commissioning generally forms part of ensuring installed equipment and systems are operating as required before they enter normal service.

Service and Repair Work

The HVAC Service Team provides:

• Maintenance
• Troubleshooting
• Repair services

across customer sites.

The apprentice will support senior technicians during these activities while developing practical experience.

Because this is field-service work, candidates should be comfortable travelling to customer locations rather than expecting to work permanently from a single workshop.

Driver’s Licence Is Required

Applicants need a:

Valid driver’s licence.

They must also be willing to travel within Carletonville.

Unlike the previous-experience requirement, the driver’s licence isn’t described as merely advantageous.

Candidates should therefore make their driver’s licence clearly visible on their CV.

Customer-Site Experience

Because technicians perform work at customer sites, professional communication is important.

The apprentice will be expected to communicate clearly and professionally with customers during site visits.

Candidates should therefore demonstrate both:

Technical interest and professional interpersonal skills.

Service Documentation

Apprentices will help document:

• Service activities
• Technical findings
• Parts used

These records need to meet Johnson Controls standards.

Accurate technical documentation is an important skill because maintenance teams need reliable information about equipment condition, work completed and components used.

Safety and Compliance

The successful candidate must follow:

• Safety procedures
• Compliance requirements
• Quality guidelines

Field-service environments can involve mechanical equipment, electricity, pressurised systems and other workplace hazards.

Following established technical and safety instructions is therefore a fundamental part of the role.

Training and Mentorship

One of the strongest aspects of the opportunity is the emphasis on development.

Johnson Controls states that the apprentice will build technical capabilities through:

• Structured training
• Mentoring
• Hands-on field experience

For someone entering HVAC without previous professional experience, this combination can help build both theoretical understanding and practical competence.

Skills Johnson Controls Is Looking For

Candidates should demonstrate:

• Willingness to learn
• Mechanical interest
• Ability to follow instructions
• Safety awareness
• Communication skills
• Teamwork
• Proactive attitude
• Professionalism
• Ability to learn technical concepts
• Interest in field-service work

You don’t need to present yourself as an experienced HVAC technician if you aren’t one.

The vacancy is designed around technical development.

Who Should Consider Applying?

This opportunity could particularly suit someone who:

• Has Matric
• Has a valid driver’s licence
• Lives within practical travelling distance of Carletonville
• Is interested in mechanical systems
• Wants to learn HVAC
• Enjoys troubleshooting
• Is comfortable with field-service work
• Can follow technical instructions
• Works well with others
• Communicates professionally
• Takes workplace safety seriously
• Wants hands-on technical experience

Candidates with previous refrigeration, air-conditioning or mechanical exposure could have an additional advantage.

Do You Need N2 or N3?

Based on the requirements provided, N2 or N3 isn’t listed as a minimum requirement.

The stated educational requirement is:

Matric certificate.

Candidates shouldn’t impose additional requirements on themselves that aren’t contained in the vacancy.

If you do have N-level Mechanical Engineering, Electrical Engineering, refrigeration training or another relevant technical qualification, include it because it could strengthen your application.

Thabang’s Tip

This is a particularly interesting opportunity for candidates trying to enter a technical trade without already having years of experience.

Johnson Controls explicitly says previous HVAC, refrigeration or mechanical exposure is:

“an advantage but not required.”

So don’t write your CV as though you’re applying for a senior technician position.

Instead, demonstrate technical potential.

If you’ve worked on mechanical projects at school or college, helped with air-conditioning equipment, used tools, completed practical subjects or have other genuine mechanical exposure, include it.

Your CV opening could be something along the lines of:

Matric graduate with a strong interest in HVAC and mechanical systems, seeking practical technical training and field-service experience. Valid driver’s licence with a strong commitment to safety and continuous learning.

And don’t overlook the driver’s licence. Unlike previous HVAC experience, a valid driver’s licence is specifically required.
