As summer temperatures soar, many drivers face the frustrating issue of car AC cooling failure. A faulty cooling system not only makes driving uncomfortable but can also cause fatigue and reduce concentration, increasing safety risks. Experts say most of these problems can be prevented by using the AC correctly and maintaining it regularly.
To avoid car AC cooling failure, drivers should follow the right start-up process. First, start the engine, open the windows, and use the outside air setting to push out hot air. After a minute, switch to recirculation mode and gradually close the windows. Turning off the car without turning off the AC is a common mistake that puts pressure on the compressor, leading to damage over time.
Smoking inside the car also affects AC performance. When smoke circulates in recirculation mode, it causes odours and clogs the internal filter, reducing cooling efficiency. Another mistake is sealing leaks with adhesives like super glue, which can corrode internal parts.
Regular maintenance is key. Experts recommend cleaning or replacing the filter every 30,000km, checking refrigerant pressure with proper tools, and monitoring radiator water and engine oil. Musty smells or stale air often indicate mold or odour buildup in the system. If cooling suddenly stops, there may be a refrigerant leak or compressor issue, and the AC should not be used until checked by a specialist.
When buying a car, check if the AC cools within 2–3 minutes while stationary. Good cooling without pressing the gas pedal indicates a healthy system.
Following these simple tips can save drivers from costly breakdowns and ensure a safe, comfortable journey during peak summer heat.
