If your system was installed in 2024 or beyond, it will likely use Puron Advance, also known as
Explore Carrier's New Refrigerant. Puron Advance is Carrier's new refrigerant that will replace Puron in all residential ducted and ductless and light commercial products.
Introducing R-454B
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.
R-454B, known commercially as Puron Advance, is Carrier's refrigerant of choice for all ducted and ductless residential and light commercial applications.
In response to these concerns, Carrier products in 2024 and beyond are using a more eco-friendly alternative to R-410A, known as Puron Advance or R-454B. This new non-ozone depleting refrigerant provides efficient cooling while minimizing environmental impact with a low global warming potential .
The replacements for R-410A are the two A2Ls, Forane® R-32 and R-454B. Forane® R-32 can be used in new equipment designed specifically for mildly flammable refrigerants as a replacement for R-410A equipment.
R-410A PHASE-DOWN TIMELINE
In 2024, we will jump to a 40% decrease in production. We will reach a 70% decrease by 2029. In 2034, we will see 80% less R-410A being produced than it is today, and the phase-down will end in 2036 with another 5% reduction.
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.
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.
Comprehensive Environmental Impact Metrics
This means systems using R32 typically consume less energy over their lifetime, resulting in fewer indirect emissions. R454B, while also efficient, may require a larger charge size to achieve similar cooling performance, which can increase its overall environmental footprint.
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.
In December 2022, the EPA unveiled a refrigerant ban that will go into effect between 2025 and 2026 (depending on the industry). The result? R-410A is out, shaking up the HVACR industry, which relies heavily on this refrigerant.
Read on to learn why equipment prices keep going up. Have you noticed how high heating and air conditioning system prices have gotten? At the end of 2023, several leading HVAC equipment manufacturers publicly announced upcoming price increases for residential equipment in 2024.
“Training is also going to figure prominently this year, as technicians will need to learn how to install and service the new mildly flammable (A2L) refrigerants, such as R-32 and R-454B, that will be replacing R-410A in air conditioners and heat pumps.” Happy New Year!
ComStar's RS-53 (R470A) is the world's only drop-in retrofit replacement for existing R410a systems.
New air conditioning systems using R32 and R454B are anticipated to be more expensive than R410A systems. This higher cost is primarily due to the need to redesign systems to safely handle mildly flammable refrigerants.
R-32 has a higher pressure ratio than R-410A. Basically, a higher pressure ratio means the refrigerant can cool more with less refrigerant, which also means less electricity is required for the system to cool your home.
It's official! 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.
2024 models are integrating air purification technologies to improve indoor air quality, including: UV-C Light Systems: Kill bacteria and viruses within the unit. Electrostatic Filters: Capture microscopic particles like allergens and dust. HEPA Filters: Remove up to 99.97% of airborne contaminants.
As a part of this plan, R-410A refrigerant will be gradually phased out of production. The objective is to replace it entirely with A2L refrigerants over time. Starting in 2025, HVAC manufacturers can no longer make equipment that requires 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.
R-454B is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in current HVAC manufacturing.
The New Refrigerants
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. These refrigerants perform similarly to traditional refrigerants like R-410A but with a significantly lower environmental impact.
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.
