Why Is My Car Aircon Not Cold? The aircon of your car serves as your best friend, especially when you are driving around on a hot day. However, this will not always be the case as sooner or later, your aircon will give up on you.
This will usually be the case especially for older cars or cars that do not have a regular maintenance program. Besides the fact that such situations bring inconvenience, it could also be a potential health hazard.
Hence, if you are starting to notice that your car aircon is no longer working properly, it is time to do a thorough check-up. In this article – Why Is My Car Aircon Not Cold, we listed down some of the most common problems.
You might have a problem with the amount of refrigerant in the aircon system.
Based on the principles of heat transfer, your car aircon pumps the hot air out of your car. At the same time, it replaces air mixed with refrigerant. If your refrigerant level is low or if the refrigerant itself is no longer existent, heat transfer can no longer happen.
Try to recall the last time you’ve had recharged your refrigerant. If it was not too long ago, then there’s probably a leak somewhere. However, there are a lot of car repair professionals that you can contact. Just make sure that they are reliable enough and have a good track record.
The next suspect you should check is the aircon condenser. The main purpose of this part is the re-cooling of the hot refrigerant that had been compressed.
However, since this process utilizes the airflow coming from the front of your car, it can easily be blocked by debris collected. With the condenser now blocked, the heated refrigerant has no way to cool down. Leading your aircon to only expel hot air. If this is the case.
But in the case that the condenser is clear of any debris after you thoroughly checked it, it can be assumed that it is broken and no longer functions as it was originally intended. This is most likely the case especially if you find traces of puncture on it.
In most instances, punctures cannot be repaired and you can only replace the whole thing.
If your car had not been used for a long time, some parts will experience some sort of a shock. One of the affected parts, in this case, is the compressor.
Since it is a vital part of the circulation of cool air inside the car, a malfunctioning or broken compressor can lead to the lack of cool air coming out of your car.
Hence, it is important to start your aircon at full blast for at least 10 to 15 minutes every three weeks. Even if you won’t be using your car soon. This way, you can avoid having problems with your compressor, as well as the other parts in your car’s aircon system.
If all of the parts appear to have no issues at all, then the fault might be on the electrical wirings composing the aircon system. However, this is extremely hard to diagnose especially if you have not been trained.
If the faulty wirings can easily be seen and repaired, you can attempt to do it yourself. However, it is better to contact a professional to do it for you to avoid making things worst in case you have a mistake.
