The air conditioning of your car requires maintenance every two years or at least once a year to make sure that it is functioning properly. Since there is a natural occurrence of wear and tear, the AC in your car may develop a problem after some time, which makes it not as effective in producing cool air. You need to know some important things about auto AC repair and how you will be able to identify them when it is needed. Here are the things you need to know about.

There is No More Cool Air

There will come a time when your ac system is no longer working how it is supposed to. Even if you make it full blast, the air that is coming out of the vents does not have the same cold temperature as it used to have. This could be an indication that you require an auto AC repair because hot air is already coming out. For instance, lacking cool air could be because of a failed compressor.

Weird Noises

If you are already hearing weird noises from your AC, that is a clear sign there is some damage. Most of the time, you should not hear anything from your AC while it is running. Actually, it should be relatively quiet apart from the fan sound at a higher speed. If you are noticing strange sounds, then there is a problem. Your AC system uses a compressor that puts pressure on the whole system, which allows the coolant to go where it is supposed to. A pulley bearing is used to operate this so that in case there is a breakdown, it will produce a grinding or squealing sound, which is a sign that an auto AC repair is needed.

There is a Foul Smell

If you notice that there are foul odours that are coming out of the AC vents when you turn it on, then this is not good. It could be an indication that the air filter needs a replacement because it is already dirty. It could also be caused by mould growth that is affecting your AC unit or evaporator case. The nasty odour when your car's AC is turned on is a clear sign to have it checked and repaired right away. The foul smell can lead to health and respiratory problems.    

Use this important information so that you can know about auto AC repair and when you should have it done.
