What causes a car to lose Freon?
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.
