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.

Why does Freon get low?

The most common cause for low freon is a leak somewhere in your line. If there is even a minuscule break or bend in the refrigerant line, the high pressure of the system will make it leak out over time. These leaks can start from damage or erosion.
