Why is R-22 refrigerant illegal?

Author: Noe Runolfsdottir  |  Last update: Wednesday, July 1, 2026

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.

Why is R-22 banned?

Because R-22 depletes the ozone layer, production and import was further limited in 2010. In 2020, R-22 will no longer be produced or imported. After 2020, only recovered, recycled, or reclaimed supplies of R-22 will be available. The production (not use) of R-22 is being phased out.

Is it illegal to use R-22 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.

Can you flush R-22 to R-410A?

When you replace an air conditioner or heat pump and upgrade from R-22 to R-410A, the ideal solution is to replace your refrigerant lines. This is because the mineral oil used in R-22 systems is not compatible with the new R-410A refrigerant and oil.

What happens if you put R-410A in a R-22 system?

The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur.

R-22 Refrigerant Ban - What does that mean for Homeowners? On News 4 San Antonio.

Can I convert my R-22 to R-410A?

You cannot just switch refrigerants because R410-A and R-22 have different chemical properties. R410-A operates at a higher pressure. If you put R410-A into an R-22 system, the parts will rupture due to the increased force.

Will R-410A be phased out?

The impending phaseout of R-410A, a widely used refrigerant in HVAC systems, marks a huge shift for homeowners and the HVAC industry. Set to take effect on December 31, 2024, this change is driven by global efforts to reduce greenhouse gas emissions and comply with environmental regulations.

How much does it cost to convert R-22 to R-410A?

How much will an R-22 to R-410A conversion cost? The actual cost will depend on many things, including where you live, but most of the time R-22 conversions start at around $2,000 and go up from there. The higher end of that range is somewhere around $4,500 to $4,600.

Can you use the same line set from R-22 to 410A?

To retrofit an R-22 system with R-410A system your line set must not be more than 25-50 feet in total distance. If the line set is longer than this, you will have to replace the line set with larger lines.

What refrigerant is drop-in replacement for R-22?

The information below will try to dispel some of these myths. Arkema recommends using Forane® 427A (R427A) - The EASY RETROFIT™ for your r-22 retrofit solution. When it comes to drop-ins, the truth is that there are none. The hope of “drop-in” refrigerants has become common over the years.

How long will R22 refrigerant be available?

In 1987 an agreement called the Montreal Protocol was signed to begin the worldwide phase out of ozone-depleting CFCs and in 1992 HCFCs were added. In 2010, manufacturers were no longer able to produce new equipment designed with R22 and at the end of 2020, production and import of R22 will be eliminated.

What is the new refrigerant for 2025?

The new EPA refrigerant regulations for 2025 will phase out the use of high-global warming potential (GWP) refrigerants like R-410A, replacing them with more eco-friendly alternatives, such as R-454B and R-32.

How much does R22 freon cost per pound?

R-22 refrigerant prices range from $90 to $250 per pound. Since you'll need between 6 and 12 pounds to refill a home AC, costs can reach between $660 and $2,400 for a refill of R-22 refrigerant.

Can you still buy R-22 refrigerant?

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.

What can I use instead of R-22 refrigerant?

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.

When did HVAC stop using R-22?

In 2010, the U.S. stopped the sale of new air conditioning units that use R22. That means new air conditioners in US manufactured after 2010 are prohibited from using R22 coolant. R22 phaseout in 2020 means that it's completely illegal to manufacture or import R22 into the country.

What happens if you mix R-22 with another refrigerant?

Mixed refrigerants can cause increased system pressures and temperatures changing them for the worse. This can result in ineffective compressor cooling and possible compressor damage, ineffective cooling, and metering device malfunction. Different types of refrigerants are not meant to be mixed.

Can R-454B be retrofitted into existing R-410A or R-22 systems?

ACHR NEWS: As a mildly flammable refrigerant, R-454B can't be retrofitted into existing R-22 and R-410A systems.

Can you top off R-22 with 410A?

Never mix R-22 and R-410a.

Why is 410A so expensive right now?

Regulatory Changes: As the phase-out continues to restrict production levels and importation, the R-410A price will likely increase. Manufacturing Costs: Fluctuations in the cost of raw materials and manufacturing can also influence the price of refrigerants.

Can I use R32 instead of R-410A?

R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.

How much higher is the pressure of R-410A than R-22?

Tube-side materials in R-410A coils need to be thicker due to the higher operating pressures associated with R-410A relative to R-22. We're not arguing that there's not a difference in operating pressure between the two. There is – roughly 130 PSI for R-410A evaporators compared to about 70 for R-22.

What is the new Freon in 2024?

R-454B is the new refrigerant in 2024. By 2025, the EPA's required phaseout of R-410A will be in full effect, with production, importation, and distribution no longer allowed. HVACR businesses must be evaluating their current choices in coolant and ready to make the jump.

Will there be a drop-in replacement for R-410A?

ComStar's RS-53 (R470A) is the world's only drop-in retrofit replacement for existing R410a systems. At 909, RS-53 has a GWP that is effectively 56% lower than R410a. Additionally, RS-51 (R470B) has a GWP of 717 which is 80% lower than R404a, R507 and half of R448A and R449A.

Why is R-32 refrigerant banned?

Changes to the Dangerous Goods Legislation, effective in 2021, has new categories for A2L refrigerants. R32 is a synthetic greenhouse gas. If released to the atmosphere it can contribute to climate change. R32 is a flammable refrigerant.
