Aircon gas r32 vs. r410a: What’s the Difference?

Air conditioners come in all shapes and sizes and use different gases to run. Two of the most common gases used are r32 and r410a. So, what’s the difference between them? In this blog post, we will discuss the pros and cons of each gas so that you can make an informed decision about which one is right for you!

What Is The Purpose Of AC Refrigerant Gas?

The purpose of AC refrigerant gas is to transfer heat from the inside of your home to the outside. This process is what makes your home feel cool and comfortable during the hot summer months! Refrigerant gases are what make this possible, and there are two main types: r32 and r410a. Let’s take a closer look at each one to see the pros and cons.

What is R410a Gas?

R410A is a type of refrigerant used in air conditioners. It is a hydrofluorocarbon (HFC) that does not contain chlorine, making it environmentally friendly. R410A was introduced in 1991 by US firm Allied Signal and has since become the standard refrigerant for new air conditioners in the US.

R410A can work at much lower temperatures than other refrigerants, making it ideal for use in air conditioners. The gas can also maintain a constant temperature, making it more efficient than other types of refrigerants.

R410a has been around for longer and is the most common type of refrigerant gas used in air conditioners. It is very reliable and durable and is less likely to cause problems than r32. However, r410a is not as energy-efficient as r32 and can be more damaging to the environment.

What is R32 Gas

R32 is a gas of organics that is similar in structure to R410A. It has a low global warming potential (GWP) and offers excellent pressure drops and temperature transfer capabilities. Originally invented in the 1960s, it is now widely used in China, India, and the Japanese market.

R32 is classified as A2, which means it is mildly flammable. R32 is still considered safe for use in 0 op dpi applications despite its flammability. Overall, R32 appears to be a good solution for those looking for an environmentally friendly option with good performance characteristics.

R32 is a newer refrigerant gas becoming more popular in air conditioners. It is known for being more energy-efficient than r410a, which will save you money on your energy bill! R32 is also less damaging to the environment, which is important to many people. However, it should be noted that r32 can be more corrosive than r410a, so it is important to have a professional install your air conditioner if you choose this option.

What Is The Difference Between R32 And R410a?

The main difference between r32 and r410a is that r32 is newer and more energy-efficient, while r410a is more common and more durable. Here is the comparison detail.

Impact on Global Warming and Climate Change

R32 and R410a are refrigerants that can reduce greenhouse gases. These refrigerants can be compared to the CFCs that were used in the 20th century. The CFCs were discovered to have damaged the ozone, and they have now been eliminated. R32 and R410a are refrigerants that can be used to replace CFCs.


In this R32 vs. R410a comparison, we’ll be looking at the two most common types of refrigerants used in air conditioners. Both R32 and R410a are hydrofluorocarbon (HFC) refrigerants, meaning they don’t deplete the ozone layer.

However, there are some important differences between the two. R32 has a global warming potential (GWP) of 675, while R410a has a GWP of 2088. This means that R32 is significantly less harmful to the environment than R410a.

In terms of chemistry, R32 is a single-component refrigerant, while R410a is a blend of two components (difluoromethane and pentaerythritol tetrafluoroethylene).


R32 is often used in air conditioners, while R410a is commonly used in refrigerators and freezers. R32 is also starting to be used in some types of heat pumps.


R32 is classified as flammable gas, while R410a is not. This means that R32 requires special handling and training for those who work with it. However, both gases are safe for use in household appliances.


The cost of R32 and R410a varies depending on the supplier and the market conditions. In general, R32 is more expensive than R410a.

Is It Possible To Upgrade Refrigerant In An Existing Unit?

If your air conditioner uses R410a and you want to upgrade to R32, it is possible to do so. However, it is important to note that this should only be done by a qualified air conditioner professional. Upgrading and refilling refrigerants can be a complex and dangerous process, so it is not something that should be attempted by someone who is not experienced.

Final Thoughts

While R32 may be the more environmentally friendly option, choosing the right refrigerant for your needs is important. If you are unsure of which one to choose, we recommend speaking with a qualified AC contractor. They will be able to help you select the best option for your home or business.
