Skilled trades career profile
Air-conditioning and refrigeration technician
Installs, services and repairs refrigerators, air conditioners and cold storage systems. Handles refrigerant gases safely, finds leaks, and tests electrical and cooling performance.
Student snapshot
A room air-conditioning job may involve a warm room, weak airflow and a client who needs the unit back in use. A cold-store job also needs a clear log of the stored goods and their required conditions. Real work with refrigerants or electrical parts needs the right trained staff. The two settings have different costs when a unit stops.
What the work actually involves
Install and service cooling systems, check gas pressure, clean components, diagnose electrical or airflow faults, and follow safety rules. Skills to notice: Electrical installation and testing, Mechanical diagnosis and repair, and Hand and power tool use.
A day in the life
A technician may review a service request, check the unit information, and plan the work and safety controls. They may inspect airflow and controls, test system performance, locate a fault, and record findings. Refrigerant and electrical work require appropriate training and procedures.
Where this work happens
You may work in homes, shops, schools, cold rooms, service sites, and repair workshops.
Who this may fit
You may enjoy connecting mechanical, electrical, and temperature clues to understand why a cooling system behaves differently. The work can involve physical tasks, customer sites, and careful environmental and safety procedures.
India pathway after Class 10 and Class 12
A related Directorate General of Training (DGT) option is the Refrigeration and Air Conditioning Technician CTS trade. DGT lists it as a two-year course, with Class 10 Science and Mathematics or a same-sector vocational subject as the entry qualification. Check the current institute affiliation, hands-on practice, safety and refrigerant training, and state admission notice.
Skills to build in school
- Learn circuit symbols and basic electrical safety rules.
- Compare supplied mechanism drawings and list questions for an authorised test.
- Learn tool names and safe handling before practical work.
- Choose the right safety gear and explain why it matters.
Reality checks
- Refrigeration work may require a traceable history of temperatures and service.
- A missing log interval leaves uncertainty even after a reading returns to range.
- Ask which systems, supervised practice and safety preparation the course covers.

Career mission
Show how an air conditioner moves heat
Explain the basic cooling cycle with a simple diagram.
This 12-minute paper mission helps students try a safe piece of Air-conditioning and refrigeration technician work through Notice, Try, and Reflect steps.
ROOM -> INDOOR UNIT -> OUTDOOR UNIT -> OUTSIDE A: absorbs heat B: transfers C: releases heat Electrical energy also enters the system.
Fictional input pack
- Conceptual heat-flow drawing: ROOM → indoor unit → outdoor unit → OUTSIDE. Statement cards: A absorbs heat from room. B transfers heat through the system. C releases heat outdoors. Electrical energy also enters the system. No refrigerant handling is part of the model.
- Notice: This is a made-up situation. You can begin without knowing this career already. Read the supplied input pack for “Show how an air conditioner moves heat”. Note the source labels, fixed details and anything left unknown.
- Try: Make a heat-movement diagram on paper. Use a quick sketch, simple labels, or a small table to show the room, indoor unit, outdoor unit, arrows showing heat leaving the room, and a note about what a trained technician maintains. Keep the result small enough to finish in 12 minutes.
- Reflect: Check your work: the diagram explains the idea without asking students to open a unit, handle refrigerant, or work with electricity. Improve one small part, then write one thing you would like to ask someone in this career.
After your attempt: check an example
Match A to room→indoor, B to indoor→outdoor and C to outdoor→outside. The simplified model omits technical detail. It does not imply energy is created or destroyed or teach maintenance.
