Is R32 Being Phased Out or Banned? Facts for 2026

R32 is not banned or phased out in 2026. In the United States, it is one of the two main refrigerants approved for new home air conditioners and heat pumps. The European Union, however, has set future GWP limits that will stop R32 in certain new equipment from 2027 and 2029. Those limits apply to new equipment placed on the market, not to R32 systems already installed.

This guide from Royal Refrigerants explains both sets of rules, what they mean for existing systems, and how R32 compares with R454B and R290.

Is R32 Refrigerant Being Phased Out in 2026?

R32 refrigerant is legal in 2026 and widely used in split air conditioners, ductless mini splits, and heat pumps. People search the question because they have heard about HFC phasedowns, the move away from R-410A, and new European rules. Those changes target refrigerants with high global warming potential and, in the EU, any fluorinated gas above certain thresholds in specific equipment.

Is R32 Banned in the United States?

No. Under the EPA Technology Transitions Program, most new residential and light commercial AC and heat pump systems must use a refrigerant with a GWP below 700. R32's GWP is 675, so it qualifies. That is why brands such as Daikin, Goodman, and Amana built their post-2025 lineups around R32 refrigerant.

The HFC phasedown is a separate program. It caps total HFC supply, measured in CO2 equivalent, but it does not ban any single refrigerant on a fixed date.

Is R32 Banned in the European Union?

Not yet. EU F-Gas Regulation 2024/573 sets GWP limits of 150 for several equipment types, starting with some categories in 2027 and small split air-to-air systems in 2029. R32 at 675 is above 150, so it cannot be used in new equipment in those categories once the dates arrive. Existing R32 systems can keep running and be serviced.

Can You Still Buy and Install R32 Systems?

In the US, yes. New R32 equipment is sold and installed under normal codes, and certified technicians can buy R32 for service. In the EU, R32 equipment can be sold until each category's deadline. Always check local rules, the equipment category, and the maker's approval.

Why Are Governments Restricting High-GWP Refrigerants?

What Is Global Warming Potential (GWP)?

GWP compares how much heat a gas traps over 100 years with the same mass of carbon dioxide, which has a GWP of 1. A refrigerant with a GWP of 675 traps 675 times more heat than CO2 if it leaks.

GWP values change with the assessment basis, so always compare numbers from the same source. Learn more in our guide to which refrigerant has the highest GWP.

How Does R32 Compare With R410A?

R32 has about a third of R410A's GWP and is the main ingredient in R410A itself. It is class A2L, meaning mildly flammable, while R410A is A1. R32 systems often use a smaller charge and can be very efficient, but each system must be designed and approved for R32. See R32 vs R410A refrigerant for a full comparison.

What Is the HFC Phase-Down?

The AIM Act directs the EPA to cut US HFC production and imports to 15 percent of baseline by 2036. Supply is at 60 percent of baseline from 2024 through 2028 and drops to 30 percent in 2029. Lower-GWP refrigerants like R32 use less of that allowance per pound, which is one reason makers chose them.

R32 Refrigerant Regulations in the United States

Some states run their own HFC programs, such as California and New York, so check state rules for specific equipment. R32 systems also need A2L-rated tools and trained installers. Our 2026 EPA refrigerant rules guide covers the federal changes in more detail.

R32 Refrigerant Regulations in Europe

The EU F-Gas Regulation 2024/573 took effect on March 11, 2024, replacing the 2014 rules. It bans placing certain new equipment on the market by GWP and capacity.

What Changes in 2027?

From January 1, 2027, new self-contained (monobloc) air conditioners and heat pumps up to 50 kW, plus split air-to-water heat pumps up to 12 kW, cannot use fluorinated gases with a GWP of 150 or more. R32 is above that line, so these products move to refrigerants such as R290. The regulation allows exceptions where needed to meet safety requirements.

What Changes in 2029?

From January 1, 2029, new split air-to-air air conditioners and heat pumps up to 12 kW face the same 150 GWP limit. This covers most wall-mounted R32 units sold in Europe today. Split systems above 12 kW face a 750 limit that year, which R32 still meets, then a 150 limit from 2033.

Are Existing R32 Systems Affected?

No. These are rules on placing new equipment on the market. Installed R32 systems can keep running, and they can still be repaired and recharged with R32.

R32 Phase-Out Timeline: 2026 and Beyond

These dates apply to specific equipment categories. None of them is a blanket R32 ban.

R32 vs R454B vs R290: Which Refrigerant Is Better?

• Global warming potential: R290 is far lowest. R454B and R32 both meet the US 700 limit but not the EU 150 limit for small new units.

• Efficiency and performance: All three can be efficient. Results depend on the system design more than the gas.

• Flammability and safety: R32 and R454B are mildly flammable (A2L), with charge limits and often leak sensors. R290 is highly flammable (A3), so its charge sizes are tightly limited, which is why it suits sealed monobloc units. Read our A2L refrigerant safety guide for handling basics.

• Equipment compatibility: These refrigerants are not interchangeable. Every system is built and approved for one gas.

• Regulatory outlook: In the US, R32 and R454B refrigerant are the current standard for new home systems. In the EU, small new units are moving toward refrigerants below 150 GWP.

What Refrigerant Will Replace R32?

There is no single replacement. In Europe, R290 is the main choice for monobloc heat pumps, while low-GWP blends below 150 are being developed for small splits. In the US, R32 is itself a replacement for R410A and is not being replaced on any set date. The right choice depends on equipment type, capacity, safety codes, and local law.

Can Existing R32 Air Conditioners Still Be Used and Serviced?

Yes, in both the US and the EU. Installed R32 systems can keep running, be repaired, and be recharged with R32. Certified technicians can buy R32 in standard cylinders, such as a 20 lb R32 refrigerant cylinder. Use maker-approved parts, A2L-rated recovery and leak detection tools, and follow local safety codes. Never top off an R32 system with another refrigerant.

Should You Buy an R32 Air Conditioner in 2026?

In the US, an R32 system is a mainstream choice with no announced ban. Check these points before buying:

• Local and state rules for your equipment type

• The manufacturer, model, and warranty terms

• How long you plan to keep the system

• Whether local installers are trained for A2L systems

• Refrigerant availability and service costs in your area

In the EU, buyers of small new units should check whether 2027 or 2029 limits apply to the model they are considering. Neither R32 nor R454B is always the better choice. The right system is the one that fits your home, your budget, and your local rules.

Frequently Asked Questions

Is R32 refrigerant banned in 2026? 

No. R32 is legal in the US and the EU in 2026.

Is R32 being phased out in the United States? 

No. R32 meets the 700 GWP limit for new home AC. Total HFC supply is shrinking, but R32 has no ban date.

Is R32 banned in Europe? 

Not yet. New small self-contained units face a 150 GWP limit from 2027 and new small split air-to-air units from 2029.

How long will R32 refrigerant be available? 

For many years. Installed systems will need service long after any equipment limits begin.

Can existing R32 air conditioners still be serviced? 

Yes, in both the US and the EU.

Will R32 be banned in 2029? 

In the EU, R32 cannot be used in new split air-to-air units up to 12 kW from 2029. That is not a ban on existing systems or on the refrigerant itself.

Is R454B better than R32? 

Not always. R454B has a lower GWP, and R32 is a single gas that is simple to recharge. Equipment design matters more.

What refrigerant will replace R32? 

In the EU, R290 and other gases below 150 GWP for small units. In the US, no replacement is scheduled.

Is R32 more environmentally friendly than R410A? 

Yes. Its GWP is about 68 percent lower, and systems often need a smaller charge.

Can R32 be replaced with R454B in an existing system? 

No. They are different refrigerants, and an existing system must use the refrigerant on its nameplate.

Final Thoughts on the Future of R32

Is R32 being phased out or banned? Not in 2026, and not under any worldwide rule. In the US, R32 remains a leading refrigerant for new home AC and heat pumps. In the EU, future limits apply to specific new equipment categories from 2027 and 2029, while existing systems stay legal to run and service.
