Theoretically, Freon can last forever. It is not burned up like fuel. When an air conditioning system is in top shape, the refrigerant will be continually recycled within a closed system, to cool your home. However, as the AC tubing ages and wears out, it tends to develop leaks in the system.
Freon™ 134a refrigerant meets SAE J2776 purity standards. Freon™ 134a refrigerants are tested in Chemours laboratories that are ISO 9001 certified for their quality management system. The shelf life of Freon™ 134a is at least 10 years under normal storage conditions.
OP, refrigerant doesn't expire. If it's low, there's definitely a source where it's leaking from. If you're fine with just topping it off when it gets low that's fine but over time will damage your compressor. If you want it fixed take it to a local trusted mechanic.
(It's like how we call bandages “Band-Aids” or gelatin “Jello.”) That refrigerant cycles through the system over and over, which can make us wonder if it can ever go bad, get used up, or wear out. The truth is that refrigerant doesn't wear out, go bad, or need refills in a leak-free system.
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 gases can be reused after cleaning and separation, and there is a robust nationwide industry providing refrigerant reclamation services for big users.
While the refrigerant in your vehicle can escape even without a leak, it's often not enough to cause significant issues unless you've failed to top up the refrigerant for years. When the lack of refrigerant becomes significant though, it can cause a number of problems, including an overheating driver in the summer sun.
Freon, a brand name for refrigerants used in air conditioners, was introduced in 1930 and officially banned in the United States on January 1, 2020. Also known as R-22, it's a chlorofluorocarbon (CFC) that studies found to be harming the environment.
As mentioned earlier, Freon costs about $125 – $150 per pound. Most homeowners will pay in the range of $200 to $400 for a refill, depending on the type and size of their HVAC unit.
First, check your filters and coils for dirt and debris that may be impeding airflow. Once you've cleaned the filters and coils, run the air conditioner with just the fan so that the ice accumulation can melt off. If the AC still doesn't blow cold air, it could be that refrigerant levels are too low.
If it takes longer and longer for your home to cool off, it could indicate a problem with refrigerant. Your indoor thermostat might be inching up in temperature and humidity for no explainable reason. Another classic symptom is if your air conditioner doesn't cool well during the day, but catches up in the evening.
Well, Most systems can get by with Freon replacement every two or five years. However, the most significant exception to this rule is when there is a leak in the air conditioning system, which decreases the amount of the refrigerant in the AC unit over time.
Generally speaking, a properly maintained air conditioner can expect its refrigerant to last around 10-15 years or longer—depending on usage frequency and environmental wear and tear. To ensure your refrigerant lasts as long as possible, regular maintenance is key.
Is R22 Freon Still Available? Yes, recovered or recycled R22 is still available to purchase. However, the cost is getting higher and higher as the supply is diminishing.
Smelling like chloroform, or sweetish car coolant, Freon, while mostly odorless, is still detectable. Heavier than air, it doesn't linger for long, quickly dropping down to floor level. Though it won't make you instantly pass out, this chloroform-scented leak is still dangerous.
A Question of Supply and Demand
Therefore, maintenance people and air conditioning system specialists have less supply and are charging more for it. Some businesses have even reported thefts targeting their Freon canisters thanks to its newfound value. After 2020, R-22 won't be produced at all in the United States.
If you need refrigerant for your air conditioner, you'll need to contact a professional heating and cooling technician. Under EPA regulations, only a certified professional can recharge your home's HVAC system.
An AC leak will lead to warmer air from your vents over time. In most cases this can be fixed with a proven stop leak additive to seal up any leaks. When it's time for an AC recharge, turn to AutoZone.

Tradewater is the only climate-focused refrigerant buyback program in the world. Get paid to fight climate change by selling your old refrigerants, like Freon, to our EPA-certified technicians.
The EPA began phasing out HCFCs in 2010 and officially banned their production and import in 2020. As Freon was phased out, new HVAC systems began using a refrigerant known as Puron® or R-410A, an HFC.
It's important to note that low refrigerant levels don't always mean a leak. We often receive calls at Watkins Heating & Cooling from customers with low Freon who had their HVAC system installed by other companies.
Watch the pressure gauges for fluctuating air pressure, which confirms the presence of a leak. indicate the location of the hole or puncture. As an alternate to a nitrogen test, add an ultraviolent dye to the system and use a black light to search for traces of leaks.
Because the system is pressurized, Freon will continue to leak from the air conditioner even when it's off. A technician will inspect your system, repair leaks, and recharge the system with refrigerant.
