So, how long does an AC recharge last? Your air conditioning is not something that runs constantly, so unless you live in a very hot climate, you can usually expect a recharge to last at least three years.
The most common cause of an AC system blowing warm air is a lack of refrigerant, though, you may also have a problem with your condenser. Other possibilities include a faulty compressor, broken cooling fans, or an issue in your electrical system.
Sound Test: If your AC unit is giving off a hissing or bubbling sound, it is a good indication your Freon levels are low. You can determine where the sound is coming from by listening to all points along the line. Again, you will only hear a hissing or bubbling sound if the leak is substantial.
#1 Your Car’s AC Needs a Recharge
The most common cause of a vehicle’s air conditioner not getting cold enough is that it needs to be recharged. You can recharge your refrigerant by yourself, but to save time and make sure the job is done correctly you should make an appointment with your local professional auto shop.
There are a couple of signs that tell you when your car’s air con needs a regas. Firstly, the air being blown out of the vents won’t be as cool as it used to be, and you might find that the car struggles to get down to a nice cool temperature on very warm days. And secondly, the air con may give out a bad, musty smell.
An AC doesn’t “use up” refrigerant. So you should never need to recharge your air conditioner with more Freon—unless there’s a leak.

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.
Refrigerant Loss Causes
Factors that can contribute to freon leaks include improper installation, factory defects, as well as damage or wear-and-tear on your AC system. … Another common cause of AC freon leaks is erosion of the metal due to formic acid or formaldehyde corrosion.
There are two causes of AC system leaks – age and moisture. … The problem here is that rubber degrades over time and with exposure to heat and moisture. As that wear accelerates, the affected part will fail. Something as simple as a degrading O-ring can cause you to loose refrigerant surprisingly quickly.
Two cans will fill most modern cars. Very big or older cars might take 3 cans.
The air compressor for the A/C unit may not operate correctly when the system is overfilled with refrigerant. This can actually cause the car itself to run roughly or even die in some cases.
