Author: Philip Armstrong  |  Last update: Saturday, June 27, 2026

The replacements for R-410A are the two A2Ls, Forane® R-32 and R-454B.

What can I replace 410A refrigerant with?

What is the replacement for R-410A? A lower GWP replacement for R-410A is Forane® R-32. Forane® 32 is a stand-alone third generation refrigerant for new residential and light commercial air conditioning systems, heat pumps and other HVAC applications.

Is there a drop-in replacement refrigerant for 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.

Can you replace 410A with R-22?

R-22 uses simple mineral oil, non-toxic, safe, stable, etc. while R-410a uses a somewhat exotic Poly o Ester (POE) oil typically found in jet turbine engines. The refrigerant used MUST match the oil present in the system, which is one reason why you can't replace the R-22 with R410a in a system.

What replaces 410A in 2025?

Air conditioner and heat pump manufacturers are rolling out new refrigerants to comply with EPA guidelines. Starting in January 2025, no new HVAC systems will use R-410A refrigerant. Instead, most residential systems will use either R-32 or R-454B refrigerant, both of which have a comparably lower environmental impact.

Refrigerants 410a OUT! R32 IN! Here's Why!

What is the new Freon coming out in 2025 in the USA?

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.

Can I replace R-410A with R-454B?

No. R-454B is NOT a drop-in replacement for R-410A. Although many of the characteristics of R-454B are similar to R-410A, the use of R-454B is restricted by code and regulation to systems for which it was specifically designed.

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.

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

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.

Can I flush R-22 lines for 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.

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.

What are alternatives to R-410?

R32, R452B, and R454B replacements for R410A are all classed as 2L: mildly flammable. These A2L refrigerants offer only moderate limitations in charge for direct expansion systems and no limitations for indirect expansion systems such as chillers, when located outdoor or in technical rooms.

What is the next refrigerant after R-410A?

Variable applications: R-32 is compatible with many HVAC systems, from window units to portable air conditioners and commercial air conditioning units. Better efficiency: Choosing R-32 over R-410A ensures more efficiency. Systems using R-32 can reduce refrigerant usage, sometimes by up to 40 percent.

What is the cheapest alternative to R-410A?

RS-53 (R470A) enables users to replace R410A in existing units with minimal changes and inconvenience at low cost.

Can I change R-410A to R32?

No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.

Can you use 134a in place of 410A?

An environmentally more benign refrigerant for replacing refrigerant R410A includes a majority portion of refrigerant R32 and a minority portion of refrigerant R134a, the volumetric capacity of the replacement refrigerant permitting it to be used as a near or exact drop-in replacement for refrigerant R410A in terms of ...

Can I mix R-410A with R-22?

No, you cannot. To make a short story long, R410A and R22 are refrigerants. They are both good refrigerants and they both work, but they have to be charged in the system at different pressures. R410A is a higher pressure system and R22 is a lower pressure system.

How much does R-410A cost?

R-410 refrigerant costs $60 per pound on average, but can range from $40 to $75. Keep in mind you cannot purchase R-410A refrigerant without an HVAC pro. As of mid-2024, R-410A refrigerant prices range from $40 to $75 per pound.

Why are they getting rid of 410A?

Why R-410A Is Being Phased Out. Because R-410A operates at such high pressures, there is an increased risk of an environmentally harmful refrigerant leak during maintenance and repair work. The R-410A phase-out means new HVAC systems will use more sustainable refrigerants.

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.

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 I replace a R-22 compressor with a R-410A compressor?

The alterations will affect the air conditioning unit. Although they're both refrigerants, the higher efficiency of R-410A requires an upgrade to the equipment. For example, plan to replace the refrigerant tubing, the evaporator, condenser, and compressor. Other components might also need updates.

Is R-454B more expensive?

The limited supply and more complex manufacturing process of R454B compared to its predecessor R410A contribute to its higher cost.

Can I use the same copper piping when replacing my AC unit with R-22 to R-410A refrigerant?

If the refrigerant used for the existing unit is other than R22, R407C and R410A, the existing refrigerant piping cannot be used. If the existing unit has another use than air conditioning, then existing refrigerant piping cannot be used.

Is R-454B currently in use?

Beginning in late 2024, R454B will replace R410A in all newly manufactured HVAC systems to meet these environmental goals. This change is in line with the EPA's SNAP (Significant New Alternatives Policy) program, which ensures that the alternatives meet both environmental and safety standards.
