Car Air-Conditioning Compressor Repair

The car's air-conditioning compressor has just failed. The mechanic quoted about S$700 for the repair including the replacement of filter and the Expansion valves. What to do next?


1. Can I trust this mechanic? 

The mechanic is probably right. The cost of the repair is also reasonable. You have just checked with the other shops; 

2. Have I been taken for a ride? 

After the repair, the air-conditioning worked fine for a year or two; then, the second compressor failed suddenly. One soon realizes that he has been taken for ride.

3. How to avoid?

Compressor usually has a life span of more than 8 years. It failed in the first instance because there was not enough lubrication. The second new compressor failed again because of improper repairs.

It is unlikely that one could tell if the mechanic had carried out a proper repair job because the air-conditioner performed well; also, common instrument won't tell the difference. However, one could avoid this kind of shoddy work done by observing and listening to what the mechanic has to say about the repair.

Assess the Mechanic by Observation

 1. Observe and find out what tools and equipment that the mechanic has owned. If he does not own a air-conditioning flushing machine, most likely he is not fit to replace the compressor. This is because when the compressor failed, it will send “sprinkles “ or tiny bits of iron chip, all over the air conditioning system. These sprinkles must be removed;

2. Observe if the mechanic keeps his tools and instrument tidy and clean and that he has calibrated his equipment regularly.

This will tell the differences between a Professional and a non-Professional.

3. Find out if he has repeated customers; however, this might not be a good indication alone because many customers are more looking for cheaper repairs;

Assessment by Listening

He could have said:-
a) “We do not own flushing machine but we use air compressor and cleaning fluid to flush the system”; then he added that “we have done this for hundblacks of car. No problem”. Most likely, he has been using non-approved method to carry out the work.

b) “We will dismantle the components one by one and blow the sprinkles out using air compressor”. Avoid this mechanic as sprinkles stuck to the oil surfaces are not easily to be removed by air compressor alone; also, there is a lot of hard work to dismantle each and every component;

c) “There is no need to flush…”; then, better walk out on him and put your car in another better hand.

The Experience

The author recently replaced his air-conditioning compressor DIY. He found many old and rusty sprinkles after flushing the Evaporator. These sprinkles could have been left sitting in the Evaporator for years and some of which could have found its way to the compressor to cause the earlier compressor failure.

  24. تكييف الهواء يعمل عن طريق تبادل الحرارة من داخل المبنى إلى الهواء الخارجي. للقيام بذلك ، يجب تنفيذ بعض مبادئ التبريد الأساسية. واحدة من أهم القطع التي تجعل هذا يحدث هو ملف المكثف. هذا هو عادة ملف الألمنيوم يحيط ضاغط تكييف الهواء.

    ما يحدث داخل هذه الوحدة الخارجية هو تغيير أساسي في حالة المبرد داخل وحدة تكييف الهواء. ينتقل المبرد الذي يتغير من سائل إلى غاز داخل الملف الداخلي إلى الخارج حيث يضغط الضاغط الغاز تحت ضغط مرتفع. عندما يحدث هذا يصبح الغاز حار جدا. ثم يترك الغاز الساخن الضاغط لبدء التنقل عبر العديد من أقدام الأنابيب في ملف المكثف. وعندما يبرد الغاز ، يتغير مرة أخرى إلى شكل سائل يتجول في الداخل لبدء الدورة من جديد.
    شركة تنظيف مكيفات بالرياض
    تبدأ المشاكل الكبيرة عندما يصبح ملف المكثف مسدودًا تمامًا بالأوساخ بحيث لا يبرد الغاز الساخن في ملف المكثف بدرجة كافية لتغيير الغاز الساخن مرة أخرى إلى شكل سائل. إذا حدث ذلك ، فإن عملية التبريد لا تحدث ، ثم يتم تشغيل مكيف الهواء ولكن لا يتم تبريده. يبدأ الضاغط في الحصول على درجة حرارة عالية جدًا ، وستكون النتيجة النهائية هي وفاة الضاغط. لهذه الأسباب ، يجب أن تظل ملفات المكثف نظيفة وخالية من الحطام في جميع الأوقات عندما يكون مكيف الهواء قيد التشغيل. تنظيف الملف هو عملية بسيطة إلى حد ما ، وفيما يلي بعض الإرشادات التي يجب اتباعها عند القيام بذلك.

    1. Thanks for post.. here is the translation
      "Air conditioning works by exchanging heat from inside the building to the outside air. To do this, you must implement some basic cooling principles. One of the most important pieces that make this happen is the condenser file. This is usually an aluminum coil that surrounds the air conditioning compressor.

      What happens inside this external unit is a fundamental change in the case of the radiator inside the air conditioning unit. The radiator, which changes from liquid to gas, moves inside the internal coil to the outside where the compressor presses the gas under high pressure. When this happens the gas becomes very hot. Then leave the hot gas compressor to start moving across the many feet of the tubing into the condenser coil. When the gas cools, it changes back into a liquid form that travels inside to start the cycle again.
      Air Conditioning Cleaning Company in Riyadh
      Large problems begin when the condenser coil is completely blocked with dirt so that the hot gas does not cool in the condenser coil enough to change the hot gas back into liquid form. If this happens, the cooling process does not occur, then the air conditioner is turned on but not cooled. The compressor starts to get a very high temperature, and the end result is the death of the compressor. For these reasons, condenser files must remain clean and debris-free at all times when the air conditioner is turned on. Cleaning the file is a fairly simple process, and here are some guidelines to follow when doing so."
