Why is R22 refrigerant illegal?

Author: Cletus Daniel  |  Last update: Tuesday, June 2, 2026

R22 has been banned due to its high ozone-depleting potential. R22 leaks are highly toxic and can damage the environment and people's health. The use of R22 freon in air conditioning units has been restricted & banned from being used in any new products.

Why was R22 refrigerant banned?

In 2010, the U.S. stopped the sale of newly manufactured residential air conditioning units and heat pumps that use R-22 because of its particularly harmful impact on the ozone layer when released into the air. On January 1, 2020, the U.S. Environmental Protection Agency (EPA) banned the production and import of R-22.

Can I legally buy R22 refrigerant?

R22 refrigerant is illegal to import and manufacturer in the U.S. But it's not illegal for anyone to buy R22 freon. And it's not illegal to sell it IF you have a license. As long as the stocks last, you will be able to continue purchasing R22 from specialized dealers and form your air conditioning company.

Is R22 banned in Europe?

One such matter is the phase out of R22 refrigerant gasses that were used in old air conditioning systems. From the end of 2014, the EU Regulation 2037/2000 R22 Phase Out was fully in place. This means that it is now unlawful for anyone to recharge their air conditioning system containing R22 refrigerant.

Is it illegal to use R22 refrigerant?

As of January 1, 2020, production and import of R22 refrigerant will be illegal in the United States. Of course, continued use of your air conditioner (AC) or heat pump system using R22 refrigerant is allowed.

Is R22 Illegal? (AC Recharge Update for R22 in 2022)

Can I replace R22 with R-410A?

Since R410A refrigerant is charged under higher pressure, charging an R22 system with it will increase the force within the coolant lines. The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur. Mixing refrigerants is not an option either.

Is R22 bad to inhale?

Mist may irritate. INHALATION: R-22 is low in acute toxicity in animals. When oxygen levels in air are reduced to 12-14% by displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration will occur. At high levels, cardiac arrhythmia may occur.

What can I use instead of R22?

Freon MO99 is the gold standard for R-22 alternatives and was developed by the same scientists who engineered Freon R-22. The benefits of Freon MO99 include: Capacity — The ability of Freon MO99 to heat or cool a given space is closer to Freon R-22 than any other refrigerant on the market.

Is R22 explosive?

2. What are the potential safety risks of R-22a? Because R-22a is flammable, it can burn or explode if there is enough product concentrated in one space and the refrigerant comes in contact with an ignition source.

Is r134a allowed in Europe?

The short answer is that the Global Warming Potential (GWP) of HFC-134a is significant and there are replacement gases available that have less environmental impact. The EU has banned most uses of HFC-134a.

Can I recharge R22 myself?

As of Jan 1 2020, R22 refrigerant has been completely phased out worldwide due to its harmful effects on the ozone layer. It is no longer being produced. If you're interested in learning how to refill R22 in your air conditioner, it is important to know that this is not something a homeowner can do on their own.

Can I use R32 instead of R22?

As a solution, there are two alternative refrigerants used as substitute refrigerant for R22, namely R290 and R32. The R290 is widely used as working fluid in A/C system of Europe countries; meanwhile in Japan and South East countries, R32 is utilized as substitute refrigerant for R22 and R410A (Yu et al., 2010).

Why is R22 so expensive?

Why is R-22 refrigerant so expensive? R-22 refrigerant is so expensive because there's such a limited supply of it left. You see, R-22 is an “ozone-depleting substance” and is extremely harmful to the environment.

Can I still get R-22 for my air conditioner?

Manufacturers no longer produce R22 as part of an EPA-led phaseout. You can still use your system but likely have to replace it if there's a coolant leak. We updated this article in January 2023 to reflect the latest developments, prices, and recommendations for air conditioners that use R22 Freon or R410A Puron.

What is the new refrigerant for 2025?

What refrigerant will replace R-410A in 2025? For whole-home systems, Lennox has chosen 2025 Compliant Refrigerant R-454B due to its excellent performance for ducted systems and zero ozone depletion potential. For mini-splits, we selected R-32, designed to optimize efficiency and reliability in ductless systems.

When did cars stop using R-22?

In 1992, the U.S. Environmental Protection Agency (EPA) began phasing out R-22. It was banned from all new cars sold in the country beginning in 1995 and stopped being used in new air conditioning systems, heat pumps, and refrigeration systems in 2010.

Can you smell R22?

Freon is generally odorless in small quantities, making it difficult to detect leaks based on smell alone. However, when a leak occurs, a faint, sweetish odor may be noticeable.

Is 410A worse than R22?

Newer air conditioners are built to be used with R-410A for more efficient operation. It can absorb and release more heat than R-22, meaning your compressor can run cooler, reducing the compressors chances of overheating and burning out. R-410A also works at a higher pressure than the R-22.

Is R12 toxic to humans?

EMERGENCY OVERVIEW: Colorless, volatile liquid with ethereal and faint sweetish odor. Non-flammable material. Overexposure may cause dizziness and loss of concentration. At higher levels, CNS depression and cardiac arrhythmia may result from exposure.

What happens if you put R134a in a R22 system?

No, the compressor will fail. These two refrigerants have very different properties. One of R22 and R134a is high pressure and the other is low pressure. They don't mix chemically and don't have the same boiling point, leading to inefficiencies and eventual compressor failure.

Can you still use R22 gas?

Since 1st January 2015 it have been illegal to use R22 to main or repair your air conditioning. While you can still use your air conditioning, the legislation means you can't use additional R22 Gas to maintain or repair your system. This means if you have any problems then you might be in need of new system or unit.

Can I use propane in place of R22?

The experimental results show that the behaviour of propane is even better if compared to the theoretical cycle; from the thermodynamical point of view the R290 is an excellent candidate to R22 replacement.

Does Freon leak when AC is off?

Refrigerant can leak through even when your AC unit is turned off due to the pressure that it's under, so it's important to get it checked out as soon as possible. Refrigerant leaks can be very dangerous and should never be dealt with on your own.

Is Freon still used in fridges?

The short answer to whether new refrigerators use Freon is no. Refrigerators manufactured after 2020 no longer use Freon for refrigerant. Manufacturers used Freon for decades to cool refrigerators, despite knowing that the synthetic gas is incredibly harmful to the environment and toxic to people.

Is R-410A toxic to humans?

It's not flammable and it doesn't create carbon monoxide or other contaminants in the air as it cycles through your air conditioner. However, just because it's inherently safe doesn't mean it can't become dangerous. Any refrigerant, be it R-22 or R-410A, can be dangerous if inhaled or consumed by human beings.
