Mainly, your car itself could be the culprit. The air conditioning system operates inside of your engine compartment, a hot and dirty place that can be inhospitable to precision systems like the AC. Hoses and connections can break down when subjected to these forces, which causes Freon to leak from these new openings.
Refrigerant is not consumed or used up in normal day-to-day operations, but some cars due exhibit a slight loss over time. While some will argue that on the molecular level no system is completely sealed, when your vehicle leaves the factory, its air conditioning is essentially leak free.
A broken gasket or seal, cracked hose or other component may cause a refrigerant leak in the system. Additionally, some refrigerant does naturally escape over time, but it escapes in such tiny amounts it would take a very long time to cause the vehicle to blow warm air.
How often should you put freon in your car?
It is recommended that you regas your car’s air conditioning system every one to two years.

How long does it take for Freon to leak out of car?

How long does Freon last in a car?

The low port should read between 25psi and 45psi, and the high port should read between 250psi and 400psi. If both are low, you are likely low on refrigerant.

Although an air conditioner can still function at lessened cooling power after it loses refrigerant, it will start to sustain serious damage that will eventually lead to larger repair needs and possibly a full system breakdown.
Common AC leak Locations. Since your AC compressor is mounted to your engine and your engine moves as you accelerate and decelerate, soft refrigerant lines have to be used to carry refrigerant to and from the compressor. These soft lines can often leak at the crimps or where the lines bend.
How do you know if your AC line is leaking?
You can and should pull a vacuum, look at the reading on the manifold gauge set, let it sit for some amount of time (overnight is best), and see if the vacuum reading drops, because if it does, there’s a leak somewhere.

How long should Freon last?
Freon (which is really just a particular brand of refrigerant) lasts forever. It’s not like gas in car; it does not get “used up.” You see, your air conditioner’s refrigerant system is a “closed/sealed system,” meaning that it does not allow refrigerant to escape in any way.
What does a Freon leak sound like?
