What most often fails in a car air conditioner?

It is difficult to imagine a road trip without a working air conditioner, especially in hot weather, when the mercury levels jump above 30 ° C. Unfortunately, overuse and lack of regular inspection often ends with a visit to the mechanic. What most often fails in air conditioners? How to take care of this important system in our car? What mistakes should you avoid? We advise!

TL, д-

When traveling by car, an efficient air conditioning system is essential. Unfortunately, it is extremely prone to breakdowns and malfunctions. Poor cooling or unusual noise should be a warning sign to you. Correct use and maintenance of the air conditioner will help reduce the risk of malfunction.

Checking the condition of the radiator - pay attention to cleanliness!

Sometimes the air conditioning system is not clean enough, making it difficult for it to function properly. Dirt is especially dangerous for the condenser (also known as the radiator), which is one of the most delicate components in a car. Due to its location (at the front of the vehicle) and its design, it is susceptible to mechanical damage and contamination, such as dust, dirt or dead insects. Regular cleaning and inspection the radiator will help to avoid more serious damage (for example, compressor breakdown).

Circulating air conditioning system - coolant

No air conditioner will work without coolant... During the year, on average, 10-15% of its resources are used. The more it decreases, the worse the system works, therefore, after several years of operation, you can notice a significant drop in the efficiency of air conditioning.... In addition, the coolant absorbs moisture well, the excess of which inside the system often leads to serious failures.

The coolant mixed with oil is also responsible for the correct operation of the compressor. Lack of fluid can damage or completely capture this element, and as a result, the need for replacement, which is associated with high costs. Prevention should be remembered regularly topping up the coolant and checking its tightness minimizes the risk of failure.

The compressor is an expensive and prone to failure part of the car.

The aforementioned compressor (also called a compressor) features a complex multi-piece structure. Therefore, the cause of the malfunction may be the failure of any part. The condenser often fails - at high temperatures it sometimes causes the compressor to overheat... Contamination, most often from replacing another component, also has a negative impact. Too much oil or refrigerant can block the compressor.

System leak

It happens that the refrigerant evaporates at a rapid pace, disproportionate to the operation of the air conditioner. Usually the reason for this is the opening of the system, or rather - abraded hoses or broken expansion valve... This problem is solved by visiting a workshop or self-checking the tightness using a special dye (however, it negatively affects the compressor, so it should only be used as a last resort).

The habitat of fungi and bacteria, i.e. wet evaporator.

The refrigerant expands in the evaporator, which significantly lowers the temperature inside the system. This moisture condensation condenses and moves under the chassis, forming stains. However, this is a big problem. excessive humidity, which creates ideal conditions for the growth of bacteria and fungi. Therefore, if you smell an unpleasant odor when you turn on the air conditioner, this is a sign that the evaporator and related components need cleaning.

Remember prevention!

Contrary to appearances, air conditioning is an element of the car that is prone to damage. Regular checks and the ability to identify a problem will significantly reduce the risk of failure. A noisy system, an unpleasant smell, or poor cooling should all get your attention. Don't let driving on hot days make you uncomfortable. In the Nocar online store you can find a wide range of car accessories (including parts for the air conditioning system) of well-known brands. Check it out and enjoy a pleasant ride.
