Search for Ac compressor :

The automobile air conditioner is a hermetic system, filled with Freon gas and special compressor oil, which is dissolved in liquid Freon. The oil is necessary in order to lubricate the compressor and certain elements of the system. The AC compressor is considered the heart of the system, a quite complex and exact mechanism that works only when the whole installation is turned on. It pumps and drives the coolant across the whole system. It drains coolant vapors from the upper part of the vaporizer, and then drives them it into the condenser. In many modern systems provided with extension tubes, the compressor is considered the only mobile element of the system.

The compressor gets affected by dirt, liquid Freon on the suction side, insufficient lubrication, excessive pressure and high temperature. When dirt penetrates into the system, the wear out of the compressor increases significantly and makes further repair impossible. This means that a new compressor would be required. Sometimes the compressor works properly, silently, without disruptions, but, for some reasons, does not pump anymore. It can operate very well, but is already leaky. Malfunctions of the cross-valve can also occur. The AC compressor is a complex mechanism, and sometimes it is advisable to buy a new one, because the replacement of pretty expensive compressor springs and the repair costs, not to mention the wasted time, will make it financially unjustified.

What you need to know about air conditioner compressor replacement: lifetime limits, common defects and their signs, tips and recommendations

Manufacturers don’t give strict recommendations concerning air conditioner compressor service life. It is replaced in case of defects. Most of all, component breakdown is caused by jamming and mechanical damages.

You can determine if there’s a need to perform air conditioner compressor diagnostics because of insufficient cooling of the car passenger compartment and absence of indicative click at air conditioner turning on. There also can be noise of the working conditioner, sometimes even at switched ignition.

You should apply to a service station for compressor diagnostics. Specialists will perform visual inspection of the component for working fluid stains. Moreover, with the help of special equipment specialists will check pressure created by the compressor.

Component replacement is performed only at a service station. It requires skills and special equipment for working with toxic cooling agent. Moreover, the procedure is rather laborious: it presupposes removal of the exhaust manifold from the engine, demounting of the freon recirculation pipes and the defective compressor. In some cases washing of coolant circuit elements can be required. As a rule, replacement of the conditioner filter-drier is performed together with compressor replacement.
