Why is the air conditioning no longer cooling properly? We know it!

Reading time 4 Min.

When temperatures rise, a functioning one becomes Air conditioning an indispensable companion in the car. But what to do if the air conditioning suddenly stops no longer cools properly? There can be various reasons behind it, including a lack of refrigerant up to a defective one compressors are sufficient. In this article, we'll get to the bottom of the most common causes and show you what you can do about them.

Refrigerant is missing

Often the problem is that the air conditioning system is no longer cooling properly refrigerant. Since refrigerant evaporates over time or escapes from small leaks, it is necessary to refill it approximately every two to three years. Regular maintenance and refilling of refrigerant ensure that your air conditioning system is performing optimally again. However, for safety reasons, refilling should be done always be done in a specialist workshopto avoid risks such as frostbite caused by the gaseous refrigerant.

Broken capacitor

Another common reason for a lack of cooling performance is a damaged one Capacitor. It can be damaged by external influences such as stone chips or wear out over time. A defective condenser can significantly affect the cooling performance as it is responsible for liquefying the refrigerant. In this case, the only solution is to have the capacitor replaced by a specialist workshop.

Defective compressor

The compressors plays a central role in your vehicle's air conditioning system. It is responsible for circulating the refrigerant in the system. If the compressor breaks due to lack of use or wear and tear, the refrigerant can no longer circulate properly and the air conditioning system will no longer cool. To prevent a defective compressor, it is recommended that Air conditioning to use regularly - also in the winter. This keeps the moving parts of the compressor moving and prevents them from seizing.

Leaking hose

Leaking hoses can also be a cause of poor air conditioning performance. By adding Contrast media to the refrigerant, a leak can be easily identified. If you discover a leaky hose, it is important to have it repaired as quickly as possible to avoid further damage to the air conditioning system.

Conclusion

• Various reasons can lead to your air conditioning no longer cooling properly. From a lack of refrigerant to damaged condensers and compressors to leaky hoses - there is a solution for every problem. It is important that you visit a specialist workshop at the first signs of a lack of cooling performance in order to avoid major damage and higher repair costs. This ensures that your ride remains comfortable and cool even in high temperatures.

Causes of poor cooling performance

• Refill refrigerant: A common reason for a lack of cooling performance is too little refrigerant.
• Leak detection: Leaks in the system can lead to loss of refrigerant.
• Renew seals: Defective seals can also be responsible for leaks.
• Defective control unit: A non-functioning control unit disrupts the climate control.
• Defective expansion valve: Affects refrigerant flow.
• Defective capacitor: Impairs heat dissipation.
• Defective air conditioning compressor: Prevents the circulation of the refrigerant.
• Missing flushing after component replacement: May lead to contamination in the system.

Refrigerants and maintenance

• How do you recognize insufficient refrigerant? If the temperatures in the interior rise despite the air conditioning being switched on, this is often due to too little refrigerant. One refill is then required.
• Why only warm air comes out of the climate? This is usually a sign of too little refrigerant. A check using Contrast medium and UV lamp helps to identify possible leaks.
• How much does it cost to fill the air conditioning? The cost of refilling the refrigerant is on average between €70–100 in Deutschland.
• Refill refrigerant yourself? It is not recommended as this is without specialist knowledge serious mistakes can happen that damage the system.

How long does it take to fill the air conditioning?

• The Duration of the air conditioning service is approximately in the workshop 1 Hour.
• How often do you have the system in your car serviced? It is recommended to use air conditioning every two years to wait to maximize performance. The costs for this amount to: EUR 80–250.

Use and damage

• Can you drive with the air conditioning empty? Yes, but the air conditioning should not be turned on to avoid damage to the Air conditioning compressor to avoid.
• Always leave the air conditioning running in the car? The air conditioning should as needed, but regularly – even in winter at temperatures above approx 5 degrees Celsius - be used. This ensures sufficient lubrication and prevents contamination.
