误解 Misunderstanding

汽车冷气系统就像我们的呼吸系统，不断的在吸入和呼出空气。跟据这点，汽车使用者在让车子送去维修前必须了解，假如冷气系统里的零件坏了需要更换新零件或者需要维修，维修好了 也不能100%保证您的车冷气系统就能正常运作。这是因为它与气一起运作，虽然维修人员把坏了的零件换了过后，其它部分也可能会出现状况。气一直在零件里循环，假如这个零件坏了，不能代表其它部分没问题。有时，刚刚才换新的零件也会受到其它零件的影响而出问题。


在这个系统里，包含着许多大大小小的零件。一个依靠着一个持续运作。以维修汽车冷气系统的多年经验来说，如果一个零件坏了，就会维修那一部份的零件。比如说，冷箱(cooling coil/evaporator) 坏了，就会维修相关部分。当然，维修人员也会先确定其它部分的零件运作正常后才交车给车主。可是往往在做最后的检查下，维修人员也很难判断出其它部分的零 件是否会在往后的日子里出现状况（除非有很明显的迹象）。维修车冷气不像维修车轮胎那般，轮胎坏了，换了就无后顾之忧，还可用上好几年。可是汽车冷气系统可就没那么简单了，许多时候还得花上半个到一个小时来诊断问题在哪。

如果顾客不明白这道理的话，就会误以为那家的维修人员技术不好，维修了过后不到几天冷气又不冷了。花了好几百零吉，也花上了宝贵的时间，这是顾客最不愿碰到的事，也是我们最头痛的。希望大家看了这片文章过后，能明白其中的道理 :-)

Air-conditional is just like our respiratory system.It continuously breeding in and out the air.Before car user wanted to have any services on the air-conditional system, we must understand that although the spare parts have been repaired or changed with new one after its not functioning well, mechanicions cannot 100% confirm that the system would be good after services done also. It is because every component in this system is linking with each other. when there is one component not functioning well, we could not ensure that other components is good in condition.Sometime，although that specific component(Exp: gas pipe) has been changed with brand new one, it would have problem also in a short time which normally due to the affect of air pressure and other components' function.

During mechanicions is servising the system for a car,  if we find out that a certain component such as cooling coil/evaporator is not in good condition, we would only do services on that certain parts. Ofcause, we would ensure other components is in good condition before we return the car to car's owner. But, indeed, it is very hard for us to check out whether other parts in the sytem is good or not during our last checking (besides it have a clearly signs).

Air-Cond service is not like tyre service. When car's tyre is not good already, can just exchange it with brand new one and it have no worry to be used for a few years. In air-cond system, sometime even only for checking out the problems, it need to takes half and hours or even longer.

If customer do not understand this facts, most of them would misunderstanding that the mechanions of that workshop have no good skills, they would be mad because mechanions didn't fix they problems, after service, the air-cond is still not functioning well after few weeks. It costs money and time as well. For us as a car air-cond mechanion, we also don't want this kind of incident happen to our customers. After reading this, hope you all would be more understand with the Air-conditional System. :-)
