In today’s world, air conditioning is no longer a luxury—it’s a necessity. From homes to offices, proper AC maintenance ensures comfort and efficiency. Yet, despite their importance, many people struggle with frequent AC breakdowns due to poor maintenance or lack of technical knowledge. If you’ve ever wondered how to fix an AC, start a career as an AC technician, or enroll in a professional training program, you’ve come to the right place. With over 20 years of hands-on experience repairing appliances, HVAC systems, and PCBs, I’ll guide you through everything you need to know about AC repairing courses, institutes, and becoming a certified expert in the field.
Tools & Materials Required
Before starting your journey as an AC technician, it’s crucial to have the right tools:
- Multimeter: For checking voltage, current, and continuity.
- Screwdriver Set: Phillips, flathead, and precision screwdrivers.
- Manifold Gauge Set: Essential for measuring refrigerant pressure.
- Vacuum Pump: To remove moisture and air from the AC system.
- Pipe Cutter & Bender: For installing and repairing copper piping.
- Leak Detector: To find refrigerant leaks accurately.
- Insulation Tape & Thermal Gloves: Safety and protection.
- Soldering Kit: For small PCB or connection repairs.
- Fin Comb & Coil Brush: To clean condenser and evaporator coils.
Pro Tip: High-quality tools make repairs faster, safer, and more effective. Investing in a good set pays off in your career.
Safety First
AC systems work with high voltage and pressurized refrigerants. Safety precautions are non-negotiable:
- Power Off: Always switch off the power supply before servicing.
- Discharge Capacitors: Capacitors store energy and can give a fatal shock even after power is off.
- Proper Ventilation: Refrigerant gases can be harmful. Work in a well-ventilated area.
- Protective Gear: Wear gloves, goggles, and insulated shoes.
- Follow Local Regulations: Handling refrigerants often requires certification and proper disposal.
Understanding AC Systems
Before enrolling in any AC repairing course, it’s essential to understand the system you’ll be working on:
- Compressor: The heart of the AC system, compressing refrigerant gas to transfer heat.
- Condenser Coil: Releases heat from the refrigerant to the outside environment.
- Evaporator Coil: Absorbs heat from indoor air.
- Expansion Valve: Controls refrigerant flow and pressure.
- Refrigerant: The working fluid that cycles through the system to cool air.
Knowing how each part works helps you diagnose problems effectively and is a critical skill taught in professional institutes.
