Car Compressor Problem

Car Compressor Problems & Diagnosis

Your car compressor is often regarded as the heart of the A/C system. Just like how your heart pumps blood through your body, a compressor compresses the refrigerant gas before pumping it through the system. This is done to remove humidity and heat from the air. In most cases, compressors are very reliable and can last for approximately 10 to 15 years. It is important to keep in mind that compressors are one the key components that a car needs to function properly. Now that you have a better understanding on why it is so critical to keep your compressor in good condition, let’s take a look at some of the factors that can cause it to fail, and then what you can do to avoid them.

Common Car Compressor Problems

  • Low on oil lubricant

Try to imagine that the oil lubricant of your A/C is like blood flowing through your body. If there is insufficient blood, your body cannot work properly and will experience all kinds of problems. In this case, it would be A/C compressor failure. You should get your car compressor checked by a trained A/C professional. He or she can check the lubricant levels as well as your oil pump’s condition.

  • Electrical issues

In some cases, electrical failures can lead to buildup of acids. These acids are usually responsible for causing significant amounts of damage to other parts in addition to the compressor. If your car compressor experiences failure, it is pertinent that you check for the presence of these acids. In the presence of an electrical burnout, there’s nothing much you can fix except to replace the faulty component.

You should know that electrical issues are can be easily preventable via timely inspection. It is all about spotting and repairing damaged fuses and wiring before they take down your entire car compressor system.

  • Excess refrigerant

If you previously allowed an inexperienced individual to work on your car compressor, inadvertently adding too much refrigerant, it can result in a deadly mistake for the compressor. Adding the wrong type of refrigerant is also a big no-no.

  • Incorrect suction line size

Refrigerant lines in car compressors need to be replaced from time to time. It is pertinent that the right suction line size is used. If a line is too small or large for your system, it can cause premature compressor failure.

  • Inadequate refrigerant charge

A car A/C can leak refrigerant when the lines develop cracks or holes. After some time, the level becomes too low and the compressor will start acting up. For example, it has to work harder to pump sufficient refrigerant through the system to effectively cool your space. The unnecessary strain will cause the compressor to break down without warning.

  • Blocked suction lines

When a unit is not cooling as effectively, it could indicate that the A/C refrigerant lines have become damaged or blocked. If you do not fix the problem in time, you allow temperature and pressure to build up, overheating the car compressor.

  • Dirty coils

When mineral scales, grime, and dust build up on the condenser coils, your car’s A/C cannot expel sufficient heat from the system. The unit will be forced to run constantly attempting to cool your space. With the increased temperature and pressure, your car compressor can overheat and fail.
