Author: Prof. Patricia Watsica II  |  Last update: Sunday, May 4, 2025

Starting in 2025, the HVAC industry will shift toward using refrigerants with a lower GWP. Among the most discussed replacements are R-32 and R-454B.

How much more will AC units cost in 2025?

If you replace your AC after the phaseout begins in January 2025, your costs could increase by as much as 30%. This is because it's more expensive for manufacturers to produce HVAC systems that use the new refrigerants.

How long will 410A refrigerant be available?

Yes, R-410A will still be available for maintenance and repairs for many years. R-410A won't actually be phased out of production until the 2040s. Also, contractors can still reclaim and reuse refrigerant from older systems.

What refrigerant will Trane use in 2025?

R-454B. R-454B is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in HVAC manufacturing from 2010 until the phase-out is complete in January 2025.

What is the newest Freon replacement?

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.

R-454b Will Be The New Refrigerant Of The Future Starting 2025

What is the newest Freon?

What is R-454B? R-454B is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in current HVAC manufacturing. R-454B is a blend of R-32, a hydrofluorocarbon (HFC), and R-1234yf a hydrofluoroolefin (HFO).

Are air conditioners changing in 2025?

1, 2025, the residential HVAC market will see some big changes in the coming years. As part of the technology transition, newly purchased and installed air conditioners after that date will need to have refrigerants with a lower Global Warming Potential (GWP) than in the past, according to the EPA.

Is the new refrigerant 2025 flammable?

Yes. While 2025 compliant refrigerants have an A2L classification of mildly flammable, it poses no greater risk than common household products. In fact, there is a good chance that you are already using these refrigerants in newer cars and portable air conditioners and heat pumps.

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.

Is R-32 better than R-410A?

R32 has a GWP of 675, roughly 30% lower than that of R410A. R32 systems use up to 20% less refrigerant than R410A, making them more efficient and cost less to operate. Ozone Depletion Potential of 0. Easier to recycle than R410A, as R32 is a single-component refrigerant.

Can you install R-410A in 2025?

The EPA has allowed installation of R-410A Systems through 2025 if both the indoor and outdoor units were manufactured before January 1, 2025. R-410A Components: A Component is one unit of a system that is installed for repair. Installation Stop Date: There is no limitation on installing R-410A Components.

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 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 is the minimum SEER rating for 2025?

SEER ratings for AC units and heat pumps have increased from 13 to 14 in northern states and 14 to 15 SEER in the South and Southwest regions of the country. In terms of heating efficiency, air-source heat pumps have increased from 8.2 to 8.8 HSPF (heating seasonal performance factor).

How much is a HVAC system for a 2000 sq ft house?

How much does a new HVAC system cost for a 2,000 sq. ft. home? The costs range from $6,224 to $11,434, depending on the system type and installation requirements. Key factors include system size, type, efficiency, and local labor rates.

Can an AC unit last 40 years?

While every unit is different, and every homeowner has a different understanding of when their central air conditioner is broken beyond repair, it's fair to say that, with proper maintenance and care, you can expect a good 15 to 20 years of cooling from a new high efficiency air conditioning system.

Will R-454B units be more expensive?

Energy Efficiency: HVAC systems using the new refrigerants are likely to be more energy efficient, potentially reducing your utility bills in the long run. While you might pay more upfront for a system using R-454B or R-32, the energy savings could offset the higher initial cost over time.

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 put R-22 in a 410A system?

If you use R-22 in the same system as R-410a, the compressor is going to be trying to work two different fluids through the same coils as both refrigerants respond differently to different mechanical situations. As you might imagine, this isn't going to go well for your air conditioner or heat pump.

What refrigerant is Goodman using in 2025?

These refrigerants have a GWP much lower than R-410A, making them more environmentally friendly options for cooling and heating. American Standard/Trane, Carrier, Lennox and other major brands will be using R-454B. Goodman, Amana, Daikin and subsidies will be using R-32.

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.

What is the most hazardous refrigerant?

CFCs and HCFCs are the most harmful because they contain chlorine. These refrigerants are also relatively stable, meaning they don't get destroyed easily by rain or sunlight. This makes it more likely that they will reach the stratosphere, where the ozone layer is.

Should I wait until 2025 to buy a heat pump?

Heat Pumps are Eligible for Incentives in 2025

Heat pump rebates and tax credits are a big reason why heat pumps are worth it in California. There are several incentives for heat pump installation in California in 2025.

Which is better, R-32 or R-454B?

R32 has the advantage of being a singlecomponent refrigerant with higher energy efficiency and a smaller physical footprint. It's already in use globally, so you can be confident in its reliability. R454B, while newer, has the benefit of an even lower GWP, making it the more environmentally friendly option.

What is the HVAC law 2025?

Starting January 1, 2025, all new residential air conditioners and heat pumps must utilize A2L refrigerants. Older refrigerants like R-410, which are likely the refrigerant used by your current system, are being phased out. These new systems are designed to have a lower global warming potential (GWP).
