Why R32 is LG's choice
Throughout the heating and cooling industry, there's a need for refrigerants that have less impact on the environment. In order to address the Kigali Amendment's expectations, LG is shifting to R32 refrigerant for our split systems. In comparison to the traditional R410A refrigerant, R32 refrigerant offers several advantages that are worth considering when picking out your next HVAC solution.

Around the world, governments are setting climate goals. By transitioning to R32 refrigerant, LG aims to create solutions that align with these local and national government objectives. Here are just a few we are addressing:
The Montreal Protocol
The Kigali Amendment
The American Innovation and Manufacturing (AIM) Act
When the Montreal Protocol was created in 1987, the goal was to only phase down the hydrochlorofluorocarbons (HCFCs) that depleted that ozone layer.
In 2016, the Kigali Amendment was created to address high global warming potential (GWP) levels of hydrofluorocarbons (HFCs). Aiming to reduce HFC consumption and production by 85% by 2047, the Kigali Amendment focuses on transitioning to lower-GWP refrigerants. [1]
AIM supports the phase down of HFCs by giving the EPA the authority to regulate production and consumption, promote the use of next-generation technologies, and prioritize the reclamation of HFCs while minimizing releases from equipment.

Setting a new standard with R32 refrigerant
One key advantage of R32 refrigerant is that it is a single component, not a blend. This makes it easier to service and recycle. Additionally, R32 refrigerant requires less volume charge compared to our existing refrigerant, R410A, thanks to its higher cooling and heating performance. [2]
Bringing R32 refrigerant to North America
LG already has a successful history of using R32 refrigerant with VRF products around the world, including Europe. Now we're bringing together our expertise to North American builders so you can bring more R32 refrigerant solutions to your homeowners.
The benefits of LG using R32 refrigerant
Lower GWP <
R32 refrigerant is a chlorine-free, fluorocarbon with zero Ozone Depletion Potential (ODP) and lower Global Warming Potential (GWP) than alternative refrigerant options. It has a GWP of 675, or one-third of the GWP of R410A (2088 GWP), which complies with currently pending refrigerant regulations. [3]
No PFAS <
One of the benefits of R32 is that it doesn't contain PFAS (per-and polyfluoroalkyl substances), a substance found in other types of refrigerants. In 2023, the European Chemicals Agency (ECHA) placed PFAS on their chemical restriction proposal. [4]
Why R32 refrigerant is the best option for LG
The better choice
As a single-component refrigerant, R32 refrigerant uses fewer components compared to the other blend refrigerant options, including R454B. In addition, R32 refrigerant requires less charge volume due to its larger amount of energy per unit volume. By using less volume and being more cost-effective, R32 refrigerant is the most economical choice for LG.
Ease of maintenance
Blends are made when two or more refrigerants with different characteristics are combined. However, R32 refrigerant is considered a single-component material and therefore can be charged in either liquid or gas phase.
LG leads the way with R32 refrigerant
R32 refrigerant has a discharge temperature 10-19% higher than that of R410A. [5] LG's products effectively manage higher discharge temperatures with its sophisticated controls and inverter compressors design. Now builders can take advantage of the many benefits of R32 refrigerant for their homeowners with LG solutions and technologies as a refrigerant that reliably keeps homes warm and cool.
