How to Fix your Car Air Conditioning

Car air conditioning systems have complex and intricate design structure that does require proper knowledge to identify when it is not functioning properly. There are lot of concerns involved such as proper equipment and environmental problem when dealing with the refrigerant that needs special attention and skill. Specialized tools are also required which need trained professionals to operate them. Some common issues and relevant information are mentioned below that can help you to identify a problem with your car air conditioning system. Worn Out Compressor A common problem with car air conditioning system is the compressor, as it is the nucleus of the system. The compressor will circulate the refrigerant that will remove the heat from your car. Though the compressor is susceptible to wear and tear, over time due to its complicated design, issues such as contamination or failed parts can lead to compressor failure. First, locate the air conditioner in the engine and engage the clutch to check whether the pulley rotates. If it does not, then either the compressor may be broken or you may have to fill the refrigerant in the compressor. Additionally, check the wire leading to the clutch. Unplug the connector in the middle of the wire and run a piece of wire from the compressor wire to the battery. If a loud sound is heard then the clutch is working properly, if not you may have to replace the clutch. Refrigerant Leaks A leak in your car air conditioning system can cause it to fail. As the car air conditioning is locked, there is no reason for low level of refrigerant unless there is a leak. It is also difficult to identify a leak as the refrigerant does not puddle like oil, but instead evaporates immediately to gas as soon as it is out of the pressure of the car air conditioning system. A leak can also happen either in the compressor, condenser or the evaporator. Try to identify whether the system has a leak by using a UV leak detection kit and check whether all fittings are secure. If your identity a leak, then call in a professional to fix and refill the refrigerant in the compressor.

Other Issues One common issue is when the car air conditioning is working, but only blows cool air moderately even when it is set to maximum cool. You need to check the cooling fans, on the radiator or condenser, to see whether they are running properly. Check for any objects that might hinder the fans such as bugs, dirt or leaves. Also, check the cabin air filter for any clogs. You can also check the car air conditioning system pressure using a manifold gauge set. You can find the recommended pressure units in the repair manual. Call in a Professional As mentioned earlier, car air conditioning systems are complex. There are a lot of other issues than those already mention that can cause the system to fail. If you are a trained professional, then you can easily identify and fix the problem. But if you are not, it is always recommended to use professional services to fix the problem even if you have some idea about the problem and how to fix it. It is also possible that while fixing one issue, another problem may crop up. At such times, professional services can immediately fix all the issues at one go. Replacing a compressor or refilling a refrigerant should be done by a professional to ensure safety. You may use this guide to identify the problems or fix minor issues, but it is always good to get the help from professional services.
