The UAE's extreme summer temperatures put enormous stress on your car's air conditioning system. If your AC becomes weak after 30 minutes of driving, here are the most common causes:
1. Low Refrigerant Levels
The most common cause is a refrigerant leak. Over time, seals and hoses can develop small leaks, causing the refrigerant level to drop.
2. Failing Compressor
The AC compressor is the heart of your cooling system. In extreme heat, it works overtime and can fail prematurely.
3. Clogged Condenser
Sand, dust, and debris from UAE roads can clog the condenser fins, reducing heat exchange efficiency.
4. Faulty Expansion Valve
This component regulates refrigerant flow. When it fails, you get inconsistent cooling.
5. Electrical Issues
Faulty relays, sensors, or wiring can cause the AC to cycle on and off.
What to Do:
- Get your AC system checked before summer
- Clean the condenser regularly
- Use recirculation mode in extreme heat
- Visit a certified AC repair specialist
