Troubleshooting 3 Widespread Car Air Conditioning Repair Troubles.

When the outside temperature starts climbing, you most likely use your air conditioning more often. That increased use also increases the likelihood of something going wrong. If the a/c in your car or truck is not blowing out cold air, things could possibly get uncomfortable pretty quickly. When you visit a car air conditioning repair specialist, take a few steps to see if you're able to fix the problem yourself. Even though you cannot correct it, you will have the ability to higher explain the issue to the professional you eventually hire.

The first step in the troubleshooting process is learning the basic principles of the a/c system. The machine cools air by compressing a refrigerant called R-134a. Older systems use r-12 Freon. The refrigerant carries heat from the car to the condenser. The condenser changes the refrigerant from a fuel to a liquid, which expels the heat. Essentially, air is blown across a very cold liquid.

Check for Leaks

Leaks are often easy to spot, but they're very difficult to fix. Most automobile supply stores carry a bright dye which can be injected in to the a/c system, that'll reveal leaks. The can can have instructions for use.

There is also a valve that may reveal the PSI (pounds per square inch) inside the system. If the leak is quite bad, the machine can have suprisingly low pressure or no pressure at all. However, don't check for pressure by inserting anything in to the valve nozzle. That is called "venting," and it's illegal.

Check the Compressor

Checking the compressor is simple. Simply start the vehicle and turn on the a/c. Check underneath the hood while the vehicle is on. Compressors can be found in different shapes and styles, but generally, they're pumps on one side of the engine with large hoses. They often have valves that resemble valve stems on tires. There is typically a pulley on the leading of the device.

You are able to identify an issue if the air conditioning is running, but the midst of the pulley is not spinning. Which means the clutch of the compressor is disengaged. The issue could be due to an electric malfunction, a faulty switch inside the vehicle, or even a leak<!--td {border: 1px solid #ccc;}br {mso-data-placement:same-cell;}-->Fix ac Problems Reading. You should replace the fuses controlling the a/c. Also, try every available a/c setting to ascertain if an interior switch might just be faulty. Check for leaks to ascertain if the refrigerant is escaping. If this fails, a car air conditioning repair professional can determine why your compressor's clutch is not engaging.

Refill the Refrigerant

If the compressor seems fine and there are no leaks, you may not require car air conditioning repair at all. Turn the a/c on inside the car. If the air coming out is still slightly cool, you may only have low refrigerant levels. You can purchase a can of R-134a at any automotive supply store. You should be sure not to overfill your system. There is no benefit from adding more compared to the recommended level of refrigerant, and it increases the danger of damaging the system.

These three common steps address the most common issues with automobile air conditioners. If you troubleshoot your a/c and it still won't work, then you probably require a mechanic. At the very least you'll be able to speak confidently with the mechanic once you take your car or truck to the shop.
