The AC condenser is a very vital component found on virtually all modern automotive AC systems. Its primary duty is to convert the refrigerant coming from the compressor from a high temperature, high pressure vapor into a high pressure liquid via condensation. Similar to how the cooling system radiator functions, the vehicle car cool air passes through the condenser fins, cooling the refrigerant as it passes through until it is then liquefied. The cooled liquid refrigerant is what is used to cool the cabin when the AC is turned on.

As the AC system’s entire refrigerant goes directly through the condenser, if there is any problem with the condenser, it can impact negatively on the entire unit and should be changed as soon as noticed. Below are few ways of identifying a failed condenser


One of the first symptoms of a failed or failing AC compressor is reduced cooling. If the condenser is damaged in any way and results in the restriction of refrigerant flow, then the entire cooling system will work less efficiently. If the refrigerant cannot flow properly, then the amount of cool air that the system can produce will be significantly reduced.


A more obvious symptoms of condenser failure will be a noticeable leak. Over time, the condenser can begin to leak either because of  age or damage. When the condenser leaks, depending on where and how big the leak is, all of the high pressure refrigerant can and will eventually leak out, disabling the whole AC system. When it begins to leak it must be replaced as a whole since the condenser is one piece.

If you think that you may be having a problem with your AC condenser, then have it looked at by a professional technician,
