The gas used for air conditioning never runs out. An AC unit can operate for 8–10 years without needing a gas refill if you use it wisely. But, consumption will have an effect on the overall performance. It performs the task of converting hot air into the cold air or serving as the air conditioner’s “fuel”.
Most AC systems can last around five years without a Freon top-up, unless you live in a very hot climate. Freon is a kind of refrigerant that is recirculated in your vehicle in a closed system to cool down the interior. So, your car won’t really run out of Freon since it is reused inside the sealed system.
The first sign that your air-con needs regassing is that the air being blown from the vents is not as cool as it used to be, or it doesn’t feel any different when the AC is switched off. If you can’t remember the last time the system was regassed, it’s probably worth doing.
How often does a car AC need to be recharged?
Once every year or two is probably sufficient. Spring is a good time to do this. We advise you to schedule an AC recharge before your unit stops blowing cold air entirely. If you notice that the air coming out of your vents is not quite as brisk, give us a call.

It takes much longer than it should to cool off your home.
Your utility bills are higher than usual.
The air coming out of your vents isn’t cold.
Ice has started to build up on your refrigerant line.
You hear loud or unusual noises coming from your unit.
Topping off a car ac system can usually put you back in the deep freeze. That’s a job you can do yourself if your vehicle was made after 1993 and is filled with R-134a
R-134a
1,1,1,2-Tetrafluoroethane (also known as norflurane (INN), R-134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone

refrigerant (check the label under the hood or the specifications section of your owner’s manual to be sure).
Is it hard to recharge your car AC?
Has your car’s A/C system lost its cool? Refrigerant can leak slowly from your car’s air conditioning system over time, but recharging the system so it once again blows cold air is an easy DIY task and takes just about 15 minutes.
How do I check the refrigerant level in my car?
Place the thermometer in the center vent of your vehicle and allow the car to run for a few minutes. Read the gauges once the pressures stabilize. 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.
Why is the AC in my car not blowing cold air?
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.
Most cars hold between 28 and 32 ounces of refrigerant (or about 2—3 12oz cans), however larger vehicles and those with rear A/C will likely hold more. Check your vehicle manual for the system capacity for your specific vehicle.
Is it OK to run AC without freon?
Without any refrigerant at all, your air conditioning system would be incapable of cooling your home.
What happens when car AC runs out of Freon?
When the Freon level drops, your car’s AC unit won’t function properly. But that is not all that happens. The AC clutch will fail to engage since the level of Freon is too low for the compressor to pressurize.
What happens when AC runs out of gas?
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.
How often do you recharge Freon?
In fact, most units only need to be recharged once every two to five years – and sometimes even longer than that. The main exception to this rule is if there’s a leak in the system, which will cause the refrigerant level to drop over time.
How often should AC gas be refilled?
How often should you recharge your air-con? Most vehicle manufacturers recommend that you service or regas your car’s air conditioning system every 1-2 years.
How do I find a leak in my AC?
A technician can detect a refrigerant leak by using ultraviolet (UV) dye. An HVAC technician will send a fluorescent dye through your system to find the source of the leak. Once it circulates throughout your HVAC system, a detection lamp is used to find the leak’s exact location.
How can you tell if your AC is leaking gas?
Symptoms of Gas Leaks in a Split AC System
AC system not blowing cool air. Hissing sounds from the indoor AC unit. Frozen condenser coils. Loss of cooling power.
How much does it cost to fix an AC leak in a car?
The cost to fix a car’s AC leak could cost $100 to $800, depending on the reason for the issue. If your car’s AC system is leaking, it’s often because you have a cracked hose that needs replacing. Other culprits could require additional replacements of your sensors, the compressor, or the condenser.
