Problems with car air conditioning: causes and solutions

Car air conditioning is one of the most appreciated comforts during the hot months. However, there may be times when the air conditioner does not cool properly or even stops working altogether. In this article, we will provide you with information about the possible causes of these problems and give you some solutions to fix them.

Why doesn't the car's air conditioning cool?

There are several reasons why your car air conditioner may not cool properly. Here are some of the most frequent faults:

lack of soda

One of the most common problems is a lack of refrigerant in the air conditioning system. If the refrigerant level is low, the air conditioner will not be able to cool the air efficiently. This can occur due to a leak in the system or poor system maintenance. In this case, it is advisable to go to a specialized workshop to check and recharge the refrigerant.

Compressor failure

Another possible cause of the air conditioner not cooling is a compressor failure. The compressor is in charge of compressing the refrigerant and circulating the cold air through the system. If the compressor is damaged or not working properly, the air conditioner will not be able to cool the air. In this case, it will be necessary to replace the compressor to solve the problem.

dirty air filter

A dirty air filter can obstruct airflow and cause the air conditioner to not cool properly. It is important to check and clean or replace the air filter regularly to ensure proper operation of the air conditioning system.

What to do when the car air conditioning does not work properly?

If your car's air conditioning is not working properly, here are some solutions you can try before going to a garage:

Check the fuses

Fuses are protection devices that prevent electrical components from being damaged in the event of an overload. If the air conditioning does not work, it is possible that the corresponding fuse is blown. Check the car manual to locate the fuse box and see if any of them are blown. If so, replace it with a new one of the same amperage.

Condenser cleaning

The condenser is an important part of the air conditioning system and can accumulate dirt and debris over time. If the condenser is dirty, it may affect the performance of the air conditioner. Clean the condenser with pressurized water and a mild detergent to remove any accumulated dirt.

Frequently Asked Questions (FAQs)

1. How much does it cost to repair car air conditioning?

The cost of repairing the car's air conditioning can vary depending on the breakdown and the workshop you go to. In general, the price can range between 100 and 500 euros, including labor and the necessary spare parts.

2. Can I repair the car air conditioner by myself?

If you have knowledge and experience in auto mechanics, you may be able to perform some minor repairs to the air conditioning system on your own. However, it is important to note that air conditioning is a complex and delicate system, so if you are not sure what you are doing, it is advisable to go to a professional to avoid further damage to the system.


In summary, if the air conditioning in your car does not cool or does not work properly, it is important to identify the possible causes of the problem. From a lack of refrigerant to a failed compressor or a dirty air filter, there are several common faults that can affect the performance of the air conditioner. Before going to a workshop, you can try some solutions such as checking the fuses or cleaning the condenser. However, if you do not feel confident performing these tasks on your own, it is advisable to seek the help of a professional to avoid further damaging the system. Remember that keeping your car's air conditioning in good condition is essential to enjoy a comfortable and cool trip during the hot months.
