Common Air Conditioning Repairs We Handle in Gauteng(Johannesburg and Pretoria)
Our technicians handle all common and complex air conditioning repairs across Gauteng, with daily call-outs in Johannesburg, Pretoria, Centurion, Midrand, Sandton, the East Rand, and West Rand. We understand the most frequent faults caused by load shedding, high summer temperatures, dust, and aging systems, and we fix them properly—not temporarily.
Air Conditioner Not Cooling Properly
One of the most common aircon problems in Gauteng is poor or no cooling. This is often caused by low refrigerant levels, blocked coils, airflow restrictions, or compressor issues. We accurately diagnose the root cause and restore full cooling performance.
Water Leaking From Indoor Unit
Leaking air conditioners are usually caused by blocked drain pipes, dirty filters, frozen coils, or incorrect installation. Our technicians clear drainage systems, correct slope issues, and prevent recurring leaks that damage walls and ceilings.
Air Conditioner Tripping Power or Not Turning On
Power trips are common after load shedding in Johannesburg and Pretoria. These issues are often linked to faulty capacitors, damaged PC boards, wiring problems, or surge-related failures. We safely test and repair electrical components to prevent repeat trips.
Strange Noises From Air Conditioning Units
Unusual noises such as rattling, buzzing, grinding, or whistling often indicate loose components, worn fan motors, failing bearings, or debris in the system. We identify the source quickly and carry out mechanical repairs before major damage occurs.
Refrigerant Gas Leaks & Low Gas Pressure
Low gas is a frequent cause of weak cooling. We locate and repair refrigerant leaks before regassing—ensuring your system cools efficiently and complies with environmental standards. We never “top up” gas without fixing the leak.
Faulty Thermostats & Control Boards
If your aircon is not responding to settings, switching on and off randomly, or displaying error codes, the issue is often a thermostat or control board fault. We repair or replace electronic components using manufacturer-approved parts.
Fan Motor & Compressor Failures
Fan motors and compressors work hard in Gauteng’s climate. When these components fail, cooling performance drops significantly or stops completely. We assess whether repair or replacement is the most cost-effective solution and advise honestly.
Dirty, Blocked, or Ice-Covered Coils
Dust, pollen, and pollution in Gauteng often cause coils to clog or freeze. This reduces airflow, increases electricity consumption, and strains the system. We perform deep coil cleaning and airflow correction as part of our repair process.
Air Conditioning Issues Caused by Load Shedding
Load shedding frequently causes:
Electrical surges
Damaged capacitors
Blown fuses
PCB failures
We specialise in load-shedding-related aircon repairs in Johannesburg and Pretoria, helping clients restore systems safely and prevent repeat damage.
