Car Air Conditioning Problems: The Most Common Breakdowns

Car air conditioning systems play a crucial role in keeping the vehicle cool and comfortable. In hot countries like the UAE, the AC is vital and not merely luxurious. Imagine if you want to sell a car in UAE, and the buyer can’t test drive it due to an AC malfunction!

Modern cars have complex systems that require regular maintenance and cleaning. If you leave these systems without paying attention to the early warning signs, they fail and cause the inside temperature to rise significantly.

An improperly functioning or dirty AC system can increase the risk of allergies, asthma attacks, respiratory illness, and even the spread of bacteria and viruses. If you are interested in car air con servicing head over to Natrad.

During the summer, we heavily use the car’s air conditioning. However, sometimes your car is no longer cold or malfunctions randomly. This problem can be related to several failures in the air conditioning system.

A faulty air conditioning can be due to several breakdowns. Some of them can dramatically affect the car valuation in Dubai. It is usually a compressor failure, a refrigerant leak, or an electrical problem.

Compressor Failure

The compressor is essential for the proper functioning of an air conditioning system. Its role is to circulate the refrigerant through other components.

As a result, when the compressor fails, the refrigerant no longer circulates. The operation of the compressors varies according to the vehicles.

Cars with thermal engines have compressors with an accessory belt. A clutch controls the accessory belt to promote compression. When there is a small failure in the belt, the compressor can play its role perfectly.

Likewise, when the belt clutch fails, there is no more movement or cold air. Cars that use a combined compressor unit need to replace the entire unit if it fails.

Electric and hybrid models have no belt, and their compressors operate under high voltage.

Condenser Leak

You should pay close attention to possible leaks in your air conditioning system. The condenser is the element that experiences the most leaks. The condenser’s mission is to promote the passage of the hot and gaseous refrigerant to the liquid state. It has a fan that allows it to cool down after operation.

Due to its location, the condenser can be easily damaged, especially when you receive a frontal impact, sometimes by simple road debris. Because of this, the condenser will no longer allow the liquefaction of the refrigerant. Furthermore, condenser failures can also be related to the fan.

A Faulty Sensor

The role of the sensor is to measure the pressure and to communicate this information to the air conditioning computer. When the sensor is faulty, it transmits false information to the air conditioning computer. Thus, the entire air conditioning system could stop working.

Likewise, when the temperature sensor in the passenger compartment is faulty, the automatic air conditioning will no longer be able to operate as it doesn’t have all the information necessary to play its role. The most probable risk in the event of a faulty sensor is that it communicates false information that can lead to an overestimation of the temperature in the vehicle.

Gas Leak

One of the most common air conditioning failures is a gas leak in the circuit at the level of a pipe. Thus, the gas escapes, and the gas level becomes too low.

When the gas escapes, the pressure in the circuit becomes almost non-existent, which makes it very difficult to release. In this case, you must check the pipes and get a specialist to refill your air conditioning circuit with gas.

What to do when there is a problem with your vehicle’s air conditioning?

When your air conditioning no longer supplies air or only blows hot air, you must first determine the origin of the breakdown. Some quick manipulations can allow you to determine the cause of the failure. For example, turn on your air conditioning system at full power then start the engine. If you hear an abnormal noise, the problem may be with the compressor.

If you smell bad odors, it may be a fault in the cabin filter. In addition, we recommend that you always seek the services of a specialist for all work on your vehicle’s cooling circuit. It is a complex circuit, which requires certain knowledge in the field.
