Top 7 Causes Of Car Air Conditioning System Failure

This feature in your car responsible for a relaxed and comfortable drive. Although, one can drive without it, we can only imagine all the sweating and discomfort in the cabin. It is now a standard feature across all cars, in fact, it’s a necessity. The A/C is your escape from the prickling heat and humidity.

There can be a myriad of issues when it comes to the A/C system owing to complex mechanicals as well as electricals problems, like a failed O-ring seal causing Freon leak or a clogged expansion tube or just a faulty compressor.

Top Reasons for Car AC failure

  • Poor Airflow
    Upon cranking up the AC, if you notice a weak airflow from the blowers and no or low cooling, this is the most visible sign that your AC needs repairs.
  • Loud Noise while the AC is on
    Loud noises when the AC is switched on is another potential symptom of a failing AC.
  • Foul odor in the cabin
    This is probably one of the most repulsive things ever caused by a failed A/C. When you enter your car and get a whiff of musty, pungent, moldy smell.
  • Water inside the cabin
    When you park your car after a drive with the AC on, you would have observed, a puddle of water underneath the car. That’s normal and in fact, a sign of a completely healthy AC system. But when you see water inside the cabin, that is when the trouble begins.
  • AC starts to cool; then it suddenly gets warm
    This is the most common complaint we’ve heard from our customer who comes in for AC repairs. When you turn on the AC, it’s all well for a few minutes after which, you start feeling warm air blowing from the vents.
  • Burning Odor from the AC
    When you switch on the AC, you get a sharp burning smell.
  • You switch on the AC, and nothing happens
    You press the AC button, the blower throws air, but not cold air.

 The AC compressor is one of the most critical components of a vehicle’s air conditioning system. It is responsible for pressurizing the A/C system and keeping the refrigerant flowing so that it can function properly. Because it operates in a continuous cycle on and off, it is subject to wear every time the AC is turned on. Just like any other component on a vehicle, it will eventually fail and need to be replaced. The compressor is responsible for pressurizing and distributing the refrigerant. If there is any problem with the compressor, the rest of the A/C system will be affected.
