The refrigerant R22, also known as hydrochlorofluorocarbon-22 or HCFC-22, has been a widely used coolant in air conditioners, refrigerators, and chillers for decades. However, with the growing concern about climate change and ozone depletion, its production and use have been significantly curtailed in recent years. As a result, the cost of R22 has skyrocketed, leaving homeowners, businesses, and contractors scrambling to find alternatives or affordable sources.
The History of R22 and the Reasons Behind Its Phase-Out
R22 was first introduced in the 1920s as a replacement for earlier toxic and highly flammable refrigerants. It quickly became the industry standard for air conditioning and refrigeration systems due to its high refrigeration capacity, low boiling point, and stability. However, in the 1980s, scientists discovered that R22 and other HCFCs were contributing to the depletion of the Earth’s ozone layer, leading to the Montreal Protocol, an international agreement to phase out the production and consumption of ozone-depleting substances.
In the United States, the Environmental Protection Agency (EPA) began enforcing regulations to reduce the production and importation of R22, with a goal of eventually banning its use altogether. As of 2020, new R22 equipment cannot be manufactured, and the production of new R22 refrigerant has been severely curtailed.
The Impact of R22 Phase-Out on Cost
The reduced supply of R22, combined with increased demand from existing equipment, has led to a significant increase in its cost. The prices of R22 have been rising steadily over the past decade, with some reports indicating that the cost has increased by as much as 500% since 2015.
The cost of R22 can vary depending on several factors, including:
Location:
- In the United States, the cost of R22 can range from $100 to $500 per pound, depending on the location and availability.
- In Europe, the cost can be even higher, with some reports indicating prices as high as €1,000 per kilogram (approximately $1,100 per pound).
Quantity:
- Larger quantities of R22 tend to be more expensive than smaller ones, as distributors and suppliers are often willing to offer discounts for bulk purchases.
- However, the cost per pound may decrease as the quantity increases.
Recycled vs. Virgin R22:

- The continued use of R22 also contributes to ozone depletion and climate change, which can have devastating consequences for the planet and human health.
Alternatives to R22: What Are the Options?
While the phase-out of R22 is inevitable, there are alternatives and solutions that can help mitigate the impact of the shortage and rising costs. Some of the most promising alternatives include:
R410A:
- A hydrofluorocarbon (HFC) blend that is widely used as a replacement for R22 in new air conditioning and refrigeration systems.
- R410A has a significantly lower ozone-depletion potential than R22 but still contributes to climate change.
R32:
- A hydrofluorocarbon (HFC) that is used in some air conditioning systems and refrigerators.
- R32 has a lower global warming potential than R410A and R22 but is still a potent greenhouse gas.
Natural Refrigerants:
- Substances such as carbon dioxide, ammonia, and hydrocarbons that occur naturally and have negligible impact on the environment.
- Natural refrigerants are becoming increasingly popular in new equipment, especially in industrial and commercial applications.
Conclusion
The rising cost of R22 is a pressing issue that affects various industries and individuals. While the phase-out of R22 is necessary to protect the environment and human health, it’s essential to find affordable and sustainable alternatives. As the world transitions to more eco-friendly refrigerants, it’s crucial to stay informed about the latest developments, prices, and regulations.

What is R22 refrigerant and why is it being phased out?
R22 is a hydrochlorofluorocarbon (HCFC) refrigerant commonly used in air conditioning and refrigeration systems. However, it is being phased out due to its contribution to ozone depletion and climate change. The Montreal Protocol, an international treaty signed by over 190 countries, aims to reduce the production and consumption of ozone-depleting substances, including R22. As a result, the production and importation of new R22 refrigerant will cease by 2020, and the use of recycled or reclaimed R22 will be allowed until 2030.
The phase-out of R22 refrigerant is a gradual process that started in the 1990s. The goal is to reduce emissions of HCFCs and transition to more environmentally friendly alternatives, such as hydrofluorocarbon (HFC) and hydrofluoroolefin (HFO) refrigerants. While R22 is still available for use in existing systems, the rising cost and decreasing availability of the refrigerant make it essential for users to consider alternative options.
Why is the cost of R22 refrigerant increasing?
The cost of R22 refrigerant is increasing due to the decreasing supply and increasing demand. As the production and importation of new R22 cease, the supply of available refrigerant dwindles.
