Looking for a career in engineering?  Read on to find out more about our air conditioning apprenticeships.

Here at Gelidus we recognise the importance of bringing bright young individuals into the industry to be trained through our air conditioning apprenticeship programme to become some of the most capable air conditioning technicians in the UK today.

To this end we have been awarded a Certificate of Recognition by Eastleigh College for our on-going commitment to Apprenticeship training, with our past apprentices having reached finalist positions in the RAC’s ‘Student of the Year’ and the ACR’s ‘Trainee of the Year’ awards.

The company continues to seek new candidates for our Apprenticeship programme, so if you’re looking for a varied and interesting career in engineering, why not read through the sections below to find out more about becoming an air conditioning technician?

What is air conditioning?

Air conditioning is the process of controlling the temperature, humidity and cleanliness of the air in a given space.  Whilst air conditioning is generally used to keep people comfortable, it’s also used to keep IT equipment cool or maintain precise conditions for archiving and certain manufacturing processes.

What does an air conditioning technician do?

There are 2 distinct categories of work an air conditioning technician will undertake – the installation of air conditioning systems, and the service and maintenance of these systems once installed.

The work is typically a mix of mechanical and electrical work, based around the science of refrigeration.

Our apprentices will gain experience in both work categories as they progress through their training programme, and often find themselves favouring one category or the other as they become qualified.

Where does an air conditioning technician work?

Many different businesses and organisations rely on air conditioning, so air conditioning technicians are mobile in the respect that they travel to the customer’s premises to undertake the work.

This makes the work varied and interesting, with our technicians undertaking work in shops, offices, restaurants, studios, hotels, hospitals, factories, schools, colleges, airports, data centres and more.

What skills do I need to become an air conditioning technician?

To become an air conditioning technician you’ll need to have a good practical aptitude, enjoy problem-solving and working with your hands.

You’ll also need to be fit and healthy, as the work can be quite physical at times.

You’ll need to be committed to a career in air conditioning, as the training pathway to become a fully qualified air conditioning technician spans 4 years.

What does the training pathway look like for an apprentice air conditioning technician?

On starting your journey with the company you will shadow one of our experienced technicians, where you’ll learn how to work safely and keep yourself organised. You’ll learn how to use tools correctly and to look after them.

At the beginning of the academic year you’ll start a 2-year college course, with a view to gaining an NVQ Level 2 qualification in air conditioning and refrigeration.  Through the duration of this course you’ll attend college 1 day a week, and will receive on-the-job training for the remaining 4 days.

On the successful completion of your NVQ Level 2 course you’ll be re-graded as a Junior Technician and will be able to undertake certain jobs on your own.  At the beginning of the next academic year you’ll start a further 1-year college course to gain your NVQ Level 3 qualification in air conditioning and refrigeration, following which you’ll complete the remaining months to the 4-year anniversary of your start date when you’ll then be regarded as fully qualified air conditioning technician.

In conjunction with your college training you will undertake various short courses to learn how to work safely and become technically conversant with the equipment you’ll be working on.


What GSCE grades to I need to become an apprentice air conditioning technician?

You’ll need to have achieved a GSCE grade 5 (C) or above in English, Maths and a science to become an apprentice here at Gelidus, as these are the minimum grade requirements for access onto your NVQ Level 2 course at Eastleigh College.

Where are Gelidus based?

Gelidus are based in Chiltern Enterprise Centre in Theale, Berkshire.

Why a career in air conditioning?

With a career in air conditioning involving both mechanical and electrical work, it provides a breadth of useful skill and knowledge across a wide range of technical trades.  The diverse nature of the sites you’ll be visiting keeps the work interesting, and with many employers having failed to commit to Apprenticeship training over recent years, a shortage of qualified technicians in the industry helps to keep the rates of pay attractive.

There’s always an opportunity for overtime when jobs have to be undertaken on an evening or weekend, which allows you to tailor your earnings to meet your personal needs.

Once qualified and having gained some good experience in the industry, you’ll have the option to either remain undertaking a wide range work for variety, or to specialise in a certain activity (such as trouble-shooting, installing, commissioning, control work etc), to become an expert in a specific area.

Meet Jack

Jack joined us at 19 having previously had some experience in domestic plumbing.

He entered our Apprenticeship training pathway and attended Eastleigh College on a day-release basis from 2015 to 2017 where he gained his NVQ Level 2.

During this time Jack also obtained his F-Gas Category 1 qualification (licensing him to work with refrigeration gases) and his ‘Pipework and brazing’ module to give him the skills needed to install refrigeration pipework.

Jack’s strong engineering acumen was recognised by his tutors at Eastleigh who invited him to represent the college in the 2017 SkillFRIDGE competition, where after a series of inter-college and regional heats, he went on to win the National final at the WorldSkills show in Birmingham.

Jack was subsequently nominated for ACR’s Trainee of the Year and RAC’s Student of the Year awards where he was a finalist in both.

Jack continued his day-release training at Eastleigh College from September 2018 though to the summer of 2019 where he gained his NVQ Level 3 Diploma to complete his Apprenticeship.

By 22, Jack had earned the grading of ‘Technician’ and has since bolstered his skills with further technical training and site-based experience.  Now 26, Jack has achieved the grading of a Senior Technician.
