There are several possibilities why a vehicle's air conditioning stops cooling, preventing proper air conditioning during the hottest months of the year. Although the most common is the lack of enough gas in the car to cool the air, the range of options is much wider than it might seem at first, which is why it is best to detect that the car's air conditioning not cool is to go to our trusted workshop as soon as possible.
An incorrect air conditioning of the vehicle during the summer months can even affect the safety of its members, as there are not the most appropriate conditions for driving. What a priori may simply seem like an uncomfortable situation, can end up degenerating inopportune distractions or fatigue in the driver. Therefore, it should always be tried to drive in the most suitable conditions with a temperature inside the vehicle that is around 20 degrees.
Possible causes why the air conditioner stops cooling
As we have mentioned, the lack of gas is the most common option. This may be due to a possible leak in the conduits and pipes that transport it. But this cause is not the only possible one.
Another of the mechanical breakdowns that can degenerate into the lack of cooling of the air conditioning is a refrigerant leak. To make sure of this possibility, it should be checked for oil stains around the system lines. In this case, the pipes should be replaced with new ones.
The third possible alternative is a clogging of the filters due to dirt. To avoid this, it is advisable to carry out periodic maintenance of the vehicle by changing the air filters from time to time or, if necessary, cleaning the filters to obtain a correct vehicle air conditioning again.
The absence of cold air can also be due to the accumulation of dirt in the indoor fan, clogging its slits and negatively affecting the correct air flow when activating this function. One of the symptoms to detect that it is a problem related to the fan, is an unpleasant smell when activating the air conditioning inside the vehicle.
Another of the fundamental pieces in relation to the operation of the air conditioning is the outdoor exchanger. The accumulation of dirt particles in it, causing it to become clogged, raises the pressure of the gas, causing the air to not cool down and it comes out at room temperature. That is why it is so important to clean it at least once a year, ideally before the change of season.
In cases where a strange vibration begins to be heard when the air conditioning is activated, it is usually because the vehicle's compressor is damaged. If so, it is best to confirm this diagnosis with the help of professionals and, if necessary, repair or change the compressor.
Correct maintenance of the vehicle in which the aforementioned components are checked with certain periodicity, will avoid possible unpleasant situations for the driver and passengers in relation to the air conditioning of the car during the hottest months of the year.
Sometimes it is enough to simply recharge the gas in the air system in the workshop to cool the car's air conditioning, but as we can see, there are many other possible causes. Therefore, at the first symptoms of failure, it is advisable to request the help of professionals who carry out an in-depth diagnosis and determine where the problem comes from.
As we say, sometimes it will be enough to sharpen the ear or smell to detect the fault in time.
