That season of the year arrives in which air conditioning becomes an essential tool to be able to withstand high temperatures both in the office and at home or in the car.In the vehicle, it is important to make sure that the entire air system works perfectly to avoid road trips with suffocating heat inside the car.If the air conditioning fails, it is most common to think that it is due to a refrigerant gas leak in the system circuit, but this is not the only reason why the air conditioning may not work at full capacity.The compressor, which is responsible for transforming the gas into a liquid so that it circulates through the ducts and cools the air that comes out of the grilles, may be the reason for a malfunction in the air conditioning.Thus, if we notice that the air comes out hot or that the air conditioner does not work at full capacity or does not even expel air, we should think of the compressor as the possible cause of the problem.Another symptom that the compressor is not working as it should is not hearing it start up.When we turn on the air conditioning after starting the car, you should subtly hear the compressor start up.If we do not hear any noise, it is best to open the front of the car to check that there is no problem with this component, since it may be that a cable has been disconnected and the repair is simple.In the event that the breakdown is operational and the car's compressor has to be changed, we must be willing to spend around 1,000 euros on the repair, although it could be less depending on the compressor model, whose price per piece ranges between 80 and 250 euros.Any reproduction without the written permission of the company is prohibited for the purposes of article 32.1, second paragraph, of the Law on Intellectual Property.Likewise, for the purposes established in article 33.1 of the Intellectual Property Law, the company records the corresponding reservation of rights, by itself and through its editors or authors.
