Have you ever thought about how the Air Conditioner cools your room or refrigerator generates cooling? If not, have you ever heard about that the air conditioner technician instills the gas into it for maintaining the cooling of it? You must have heard about the refilling of the gas into your AC. What that gas is. Actually, that gas is known as refrigerant to fill into the condenser coils of that air conditioner. If there is no refrigerant in your air conditioner, the freezing system won’t work. The market is full of these sorts of refrigerants but what to select? What refrigerant is good for cooling and saving electricity? Here in this article, you’ll find comparison of air conditioner refrigerants to select the best one for cooling purposes and to save electricity.

The market is full of various types of refrigerants but R32, R410A, R22 and R290 are the most common practice to be used in filling or refilling of air conditioner. Air cooler-Conditioner Refrigerants comparison between R32 vs R410A vs R22 vs R290 lets you know what refrigerant is the best one and what to use for saving electricity and getting better cooling.

Types Of Refrigerants:

There are four most common types of Refrigerants are used in our history of AC. They are

  • Chlorofluorocarbons (CFCs) or ( R12) 
  • Hydrochlorofluorocarbons (HCFCs) or (R22)
  • Hydrofluorocarbons (HFCs) or (R410A & R134)

Refrigerant of an AC:

The refrigerants of air cooler or air conditioner can be in gas, fluid and liquid form. The prime aim of them is to make air conditioning possible. They are captured in the copper pipes or coils of the air conditioner to dehumidify interior air of the room. The prime aim of refrigerants is to capture heat from the room or contents of refrigerators and throw the heat out. It undergoes changes from liquid to gas and again back to liquid. What refrigerant is the best one depends on the thermodynamic properties, safety and non-corrosive nature. CFCs are the most common fluids being used in 20th century for cooling purposes.


Chlorofluorocarbons are the main concern for ozone layer depletion and greenhouse gas effect. It was banned because of its dysfunctions. R12 was used before 1994 for the filling purposes but it was banned because of ozone layer depletion.

Hydro chlorofluorocarbons:

In most of the air conditioners of today, hydro fluorocarbons are being used up to 50% air conditioners. These are a bit better than chlorofluorocarbons because they have potential not to harm ozone layer. Well, they have chlorine in them which is dangerous for green environment. Most of the governments are trying to replace that refrigerant too. R22 is the most common example of hydro chlorofluorocarbons but going to be soon left out within next few years in some countries.

Advanced hydro chlorofluorocarbons:

Ozone layer depletion is the prime concern of refrigerants and the companies are developing day by day. Now-a-days, R-32 and R410A are much better in energy efficiency and global warming but still they have chlorine in them. All HFCs have chlorine in them which is harmful for the green environment.

The difference between R22 and R410A refrigerant.

While you decide to choose the air conditioning unit, you will be required to put in to consideration some few aspects one of it is will be the type of refrigerant it uses. The main ones will be -22 and R-410A which are also known as Freon and Puron respectively. These both types of refrigerants are not interchangeable within a system. So it’s important to be careful while choosing and ensure that you   choose the correct one before you buy the system. The two refrigerants have other two major differences as discussed below.

R22 properties

This type of gas is commonly referred as Freon. This type of gas is basically among the top brands. The R22 is no longer used for installation of the new AC system as before. The gas was discontinued after being listed among the listed hydro-chlorofluorocarbon (HCFC). The gas has been shown to be a contributor to ozone depletion. Therefore it’s very clear that, in case you have a new system you will not use Freon or R22. This is because it’s very harmful to the environment.

R-410A properties

The gas is often referred to puron as the main and the common brand name that is associated with this type of refrigerant. It is hydro-fluorocarbon (HFC) and it doesn’t hurt the ozone layer.  Therefore, the gas is permitted for the new residential air conditioners and its almost becoming the standard gas in the U.S. almost all the new air conditioning units automatically use R-410A. However it’s important to check before making a final purchase. In case you are using an older unit, it’s advisable to check and confirm if it’s using the R-22 or R-410A.The gas is permitted for the new residential air conditioners and its almost becoming the standard gas all over. Almost all the new air conditioning units automatically use R-410A

Difference in performance

Beside R-410 proving to be better in ozone layer, the gas is well known in providing a better overall operation. The gas eventually absorbs and releases the heat better than R-22.this helps the compressor to run cooler and prevents overheating. In addition to that, it works at a higher pressure. This enables the compressors in the unit to handle more stress hardening it and preventing it from easier breakage s developing cracks. The systems that use R-410 also use synthetic oil for lubrication unlike the R-22 systems that uses mineral oil. The synthetic oil id more soluble, this makes the whole system more efficient and very effective. Therefore we can conclude that the R-410 works better and more efficiently than the R-22 and it has more efficient systems.

Dry charging

Some companies have not given up thus moving ahead and coming up with new systems enable they continue using R-22 in the new systems. They have come up with new ways   by producing dry charging units. This unit doesn’t have the refrigerant installed at the factory. Thus, you will have to engage a technician to charge the unit at home. The dry charge unit is not long lasting.

When it comes to decision making between the Freon and Puron, always ensure you get the one that has R-410A for a better of the two and efficient system which is also helpful to the environment.

R32 vs R410A:

R32 is the trend of the day in India and most of the companies are using it. Its global warming potential is 675. Both these refrigerants have zero ozone layer depletion but R410A has 3 times higher global warming potential than R32. R32 is also energy efficient. R32 is being used in renowned companies’ air conditioners like Daikin, Mitsubishi, Fujitsu, Panasonic, Toshiba and Gree. R410A is good refrigerant but not too good like R32. R410A is combination of two refrigerants like R125 and R32.

R22 vs R290:

R22 is the oldest and commonly used refrigerant and is being used in 50% air conditioners in India. Most of the governments have banned its usage because of its ozone layer depletion and intense global warming potential. It has 1810 global warming potential and medium ozone layer depletion. In the modern air coolers and air conditioners, this refrigerant is not being used. R290 has zero ozone layer depletion and only 3 global warming potential. It is the best and eco-friendly refrigerant. This refrigerant is the greenest and eco-friendly refrigerant. This refrigerant is highly flammable as it is hydrocarbon refrigerant.

R32 V/S R410A V/S R22 V/S R290 Properties:

Let’s look at all these refrigerants properties and see which one is the best one to use now-a-days. R32 is the good to use as it contains no ozone layer depletion property and its global warming potential is 675. R410A has no ozone layer depletion but its global warming potential is 2088 which is the highest in all refrigerants. R 22 is the first refrigerant of the market being used and has medium ozone layer depletion, also has 1810 global warming potential. R290 is the latest gas of air conditioner which is the best one to use now-a-days. It has no ozone layer depletion quality and only 3 of global warming potential. What more you need to do?

Future Security:

Selecting R290 can save our environment and can be our future security. Our next generations are looking towards us but if we’re increasing global warming and ozone layer depletion, what are we leaving for them? What we need to do is, we should use R290 as it is the ideal refrigerant for future security and would enhance our steps for our futures.

It also has very less 3 global warming potential which is less ever of all the refrigerants.

Is It Possible To Upgrade The Refrigerants?

You cannot upgrade for R-22 but you do upgrade R-410A.

R-22 is the old refrigerant in your AC which is hard to renew because of the following reasons:

  • According to the rules, EPA seems not to expect you to renew your AC instantly if this machine does not spring a refrigerant leakage.
  • The depleting stocks of R-22 refrigerant could do the fixing extra expensive than it’s worth.
  • They are non-interchangeable plus more inclined to breakdowns.
  • Those refrigerants cause your AC to generate extra noise.
  • These refrigerants can harm and damage the additional components of your Air conditioner.
  • While those refrigerants become old then it needs to be carefully disposed of concerning to limit the harm of the atmosphere later they separated from the Air conditioner.

Is AC refrigerant leak dangerous?

Yes, it is a danger the severity depends on the refrigerators gas which used. It will Harm to the environment, a risk to humans and also harm to your AC. If it seems like leakage then repair it immediately. You check if gas is leaked you can use Leak Detector Refrigerant Gas Leakage Tester HVAC Air Condition, It Detects Leakage of R22 R410A R134A CFCs HCFCs HFCs Detects High Accuracy.
