Why Your Aircon Isn’t Cooling Properly – 5 Common Problems and Fixes
When your air conditioner stops cooling the way it should, it’s not just uncomfortable—it can also be a sign that something serious is going on with your system. If you’re living in Johannesburg, Pretoria, or Midrand, you know how unbearable the summer heat can get.
At Chill Out Air Conditioning, we’ve helped countless homeowners and businesses fix cooling problems quickly and affordably. Let’s look at the five most common reasons your aircon isn’t cooling properly—and what you can do about it.
1. Dirty or Clogged Air Filters
Over time, your air filters collect dust and debris, blocking proper airflow. When this happens, your air conditioner must work harder to push air through, which reduces cooling efficiency.
Fix:
Check your air filters every month and clean or replace them if they look dirty. Clean filters can improve airflow, efficiency, and indoor air quality instantly.

2. Low Refrigerant (Gas Leak)
Your air conditioner uses refrigerant gas to cool the air. If there’s a leak, your system won’t be able to remove heat properly, resulting in warm or weak airflow.
Fix:
Refrigerant leaks must be handled by a certified technician. Our team can find and repair leaks, then refill your system to factory levels so your aircon runs like new again.

3. Faulty Thermostat
If your thermostat is broken or incorrectly set, it may not be sending the right signals to your air conditioner. This can cause your unit to cycle on and off at the wrong times—or not cool at all.
Fix:
Make sure your thermostat is set to “cool” mode and that the temperature is lower than your room temperature. If it still doesn’t work, it may need recalibration or replacement.
4. Dirty Condenser Coils
The outdoor unit (condenser) plays a major role in releasing heat from your home. When the coils become covered in dirt or grime, the system can’t expel heat efficiently, reducing cooling capacity.
Fix:
Turn off your system and carefully clean around the outdoor unit. If the coils are badly clogged, book a professional service to clean them safely without damaging the fins.
5. Electrical or Compressor Problems
If your aircon suddenly stops cooling altogether, there may be an issue with the compressor, wiring, or capacitors. These parts are essential for starting and running the system.
Fix:
This requires professional attention. Our technicians can diagnose and repair electrical faults quickly to restore full cooling performance.
