What Causes Freon Leaks In Cars?

Posted By in Maintenance Tips | No Comments »

Freon leaks in your car’s air conditioning system not only prevent your cabin from cooling down in the summer, they also cause significant environmental damage and make your system work harder to keep you cool.

Freon Leaks Causes In Cars

Unlike your gas tank which can run even while relatively low on fuel, your air conditioning system must be full of Freon in order to operate efficiently. This is because Freon is not a fuel that is consumed by the system, but rather a way of transferring heat from one area to another.

The Freon in your air conditioning system works in much the same way as the water in old-fashioned radiator heating: the Freon is pumped through tubes and pipes to carry heat to or from a specific area of the vehicle. When the system gets low on Freon, around 25 psi or less, the system will automatically disengage the compressor in order to protect it from damage.

The lubricant which keeps the compressor working is in the Freon that circulates through the system so without the correct levels of Freon, the system simply cannot keep operating. When low on Freon, the compressor quickly becomes damaged and beings spreading metal flakes through the entire system.

Causes of Leaks

There are several things that can cause leaks in your car’s air conditioning system but the most common causes are defects, wear and tear, and accidents or damage to the vehicle.

  1. Manufacturer’s Defects
  2. Air conditioning systems are made by a combination of machines and people, and sometimes mistakes are made. Mistakes can include incomplete welds, misaligned joints, improperly installed seals, and a host of other issues. These problems are usually the best to have as they occur early on in the use of the product and are covered under warranty.

  3. Wear and Tear
  4. The most common cause of leaks is, unfortunately, simple wear and tear. Rust on external components may cause leaks and these issues will typically not show up for some time. Some repairs are simple and others may be more complicated but it is best to see to it quickly as the longer your air conditioning unit it leaking, the worse the damage it will do.

  5. Accidents
  6. Whenever your vehicle is involved in an accident of any kind it is important to have the vehicle checked out to make sure everything is working correctly. What may have felt like a small bump to you may have had more serious implications on other parts of your car that won’t be noticed immediately. It is far easier to have your insurance cover any issues if you report them right away.
