At Gauteng Air Conditioning Pros, we repair all types of air conditioning systems — from wall-mounted split units in homes to large commercial HVAC systems in office buildings, shops, and factories. Our certified technicians diagnose and fix a wide range of problems quickly, saving you time, money, and unnecessary discomfort.
Here are the most common aircon issues we fix:
1. Air Conditioner Not Cooling or Heating
If your aircon is blowing room-temperature air or not switching modes, it’s often due to a refrigerant (gas) leak, faulty compressor, or thermostat malfunction. We’ll inspect the unit, identify the problem, repair or recharge the gas, and restore full function.
Ideal for: Homes, retail spaces, server rooms, and offices that depend on temperature control.
2. Water Leaks and Dripping Units
Water leaking from the indoor unit is typically caused by clogged or damaged condensate drains, a faulty condensate pump, or lack of regular servicing. Leaks can damage ceilings, walls, and flooring — especially in commercial buildings.
We clear blocked drains, repair pumps, and carry out full water-tight servicing.
3. Strange Noises or Vibrations
Grinding, rattling, buzzing, or humming sounds usually signal fan motor issues, loose components, or worn belts. Left unchecked, these noises can lead to total system failure.
We replace damaged parts, tighten fittings, and balance units for smooth, quiet operation.
4. Foul Odours from the Unit
Unpleasant smells often come from bacterial growth on dirty coils or filters. In commercial spaces, this can harm your professional image and affect indoor air quality.
We clean and disinfect your system using industry-approved products to eliminate smells and germs.
5. System Not Turning On or Tripping the Power
If your aircon won’t switch on or keeps tripping the circuit breaker, it could be due to electrical faults, capacitor failure, or compressor overload. These issues require professional testing and component replacement.
Our technicians test all electrical components and restore safe, consistent operation.
6. Low Airflow or Weak Performance
When airflow is restricted or weak, the problem is usually linked to blocked filters, dirty evaporator coils, or failing fans. This reduces comfort and increases your power bill.
We clean coils, replace filters, and ensure optimal airflow and energy efficiency.
7. Faulty Thermostats or Sensors
Inconsistent temperatures or frequent cycling could be caused by malfunctioning thermostats, temperature sensors, or control boards.
We recalibrate or replace your thermostat for more accurate climate control.
