Leading air conditioning brands use R-32 gas, a highly efficient, lower global warming potential (GWP) refrigerant. Top manufacturers adopting R-32 for residential and commercial HVAC systems include:
Daikin became the world's first company to succeed in applying R-32 to air conditioners by leveraging its expertise as the only manufacturer that develops and manufactures both air conditioners and refrigerants. 1)Values for 100 year global warming potential (GWP) from IPCC Fourth Assessment Report.
No, R-32 is not obsolete; it is currently one of the primary modern replacements for older, high-global-warming refrigerants like R-410A.
Trane is phasing in the transition to R-454B in 2024, starting with the adoption of R-454B refrigerant in its residential products, beginning with the XR15 SEER2 heat pump.
Potential Drawbacks of R32
Despite the growing popularity of R32 refrigerants, there are some potential drawbacks associated with its use. These include flammability and safety concerns and retrofitting and compatibility issues.
Select Goodman indoor comfort solutions utilize R-32, a low global warming potential refrigerant for enhanced energy efficiency. R-32 is compatible with the latest Goodman HVAC systems.
R-32 refrigerant problems generally stem from its classification as an A2L "mildly flammable" gas and its higher operating pressures compared to older alternatives. Common issues include:
A2L refrigerants, the new refrigerants for 2026, will replace R-410A in new systems. A lot about A2L refrigerants is explained in their name: The “A” means low toxicity. The “2L” is a safety classification, indicating it is mildly flammable.
Average Lifespan: What You Can Really Expect. The days of 10-year HVAC systems are over. With R-32, you're looking at 15 to 20 years of dependable service — or even longer with proper care.
Because R-32 is a highly efficient, single-component refrigerant, it is expected to remain a standard in the HVAC industry for 15 to 20+ years. As the primary replacement for older R-410A systems, it complies with modern EPA guidelines to significantly reduce hydrofluorocarbon (HFC) emissions.
Trane primarily uses R-454B as its standard next-generation refrigerant for newly manufactured residential air conditioners and heat pumps. This eco-friendly alternative is replacing R-410A to comply with EPA regulations that mandate lower global warming potential (GWP).
Yes, Carrier uses R-32 refrigerant in select HVAC equipment. While they predominantly use R-454B for residential units in North America, Carrier utilizes R-32 in various global markets (especially in Europe and Asia) and in specific commercial products like scroll chillers.
The Nissan Skyline GT-R R32 is famously nicknamed "Godzilla".
LG air conditioners use different refrigerant gases such as R22, R32, and R410A. Older LG AC models usually run on R22 gas, which provides good cooling but is less eco-friendly. Many modern LG air conditioners now use R32 gas because it cools faster and consumes less energy.
*It should be noted that R-32 makes up 68.9% of R-454B, Lennox' primary 2025 Compliant Refrigerant for whole home systems – helping it achieve an even lower GWP rating of 466.
R32 is much better for the environment: R32 has a global warming potential of 675, which is about 68 percent lower than R410A. It is not completely climate-neutral, but it is a much cleaner and more responsible choice for home cooling.
R-410A is currently being phased down rather than fully banned, with the production of new R-410A equipment already banned. The remaining supply will be gradually reduced by 85% through 2036.
Many Amish homes are built with plenty of windows to help circulate the air and bring in the cooler overnight temperatures. They open the windows on the top floors to help the heat escape while the family retreats to the lower grounds within their homes for comfort.
No, R-32 is not currently being phased out. Instead, it is actively being adopted as the new standard to replace older, high-Global Warming Potential (GWP) refrigerants like R-410A.
The most environmentally friendly refrigerants are hydrofluorocarbons (HFC) and hydrofluoro-olefins (HFO). HFCs are comprised of fluorinated hydrocarbons. While HFCs can contribute to global warming, they do not affect the ozone layer directly.
Inhalation of high vapor concentration may cause dizziness, disorientation, incoordination, narcosis, nausea or vomiting, leading to unconsciousness, cardiac irregularities, or death. Ingestion Not an expected route of exposure.
Yes, Goodman is owned by Daikin.
After countless hours of research, Trane is transitioning to using R-454B refrigerant and R-32 refrigerant in our residential cooling systems, using a phased-in approach. These refrigerants are more sustainable with a low global warming potential (GWP) and 0 ozone depletion potential (ODP).
