Car AC Leaking Freon

If your car AC is leaking Freon most likely your complaint is that the air is not blowing cold. Depending on how severe your Freon leak is, recharging it with one can of refrigerant may not last long.

Although the most popular type of Freon r134a is supposed to be environmentally friendly it was still not designed to be released into the atmosphere in large quantities.

If you continue to recharge your AC and it continues to leak out, this is not good for you or the environment.

I wrote some good articles on this subject and will direct you to them. This first article is about slow Freon leaks and auto AC repairs. There you will find some tips and strategies for locating the smaller leaks that can be extremely frustrating to find.

This next page talks about finding large car AC leaks in automotive systems. Also included on the page are links to tools to help you solve the problem once and for all.

I’m often asked if the AC stop leak systems actually work. The answer to this question really depends on where the leak is and how severe.

The AC stop leak works best on the low pressure side of the automotive A/C system.

When the system is turned off on a hot summer day there could still be 100 PSI of pressure in the low side. But during normal operation the low side pressure falls down to about 35 PSI. This gives the air-conditioning stop leak a fighting chance to take hold and stay in place.

AC leaking Freon on the high side will usually need a physical repair of the problem. High side pressures can reach over 250 psi. In most cases stop leak will not be able to stay in place in the affected areas under these types of pressures.
