Refrigerant gas does not “wear out” like oil nor is it used up like fuel. In a properly sealed system the gas can continue being compressed and released over and over, so long as it doesn’t leak out.
Can Freon get low without a leak?
The simple answer is No. There may be something wrong with the system that may seem like it is low like restricted metering devise, suction or liquid line but if refrigerant was added and now the unit works properly then there most likely a leak assuming the unit was properly charged when manufactured or installed.
Can a car AC be low on freon without a leak?

Is it normal for car AC to lose Freon?
Some refrigerant is lost naturally over time. It takes years, though, so if your car isn’t that old or the system has been recharged recently and is now blowing warm air again, chances are good that you’ve got a leak somewhere. There are two causes of AC system leaks – age and moisture.

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.
How do you know if your car AC needs recharged?
The most obvious symptom that a vehicle needs to be recharged is that there will be a noticeable loss in the overall cooling capability of the AC system. The AC system operates by circulating pressurized refrigerant, so if the amount drops too low it will eventually begin to affect the operation of the system.
