Do You Know Which Gas Are Used In Air Conditioner

The gas that’s used in air conditioners is called freon. Freon is non-flammable. It is odourless. There’s no way to detect a freon when it’s in the air. Unlike most gas, it doesn’t get used up. The chlorofluorocarbon compounds of methane and ethane are called freons.

Freon is the kind of gas that absorbs the heat from a specific space and ejects the hot air out in the environment outside the space. Freon is usually used to freeze things. Freon is commonly known as a refrigerant. Without refrigerant, refrigerators and air conditioners would cease to exist. Needlessly we can admit how vital this gas is in our daily lives.  

Can Air Conditioners Run With Low Freon?

Air Conditioners run on a gas called. The cooling process of air conditioners happens because of this gas. 

Air Conditioners can run on low freon, but it is hazardous. By running on low freon, the air conditioner takes a long time to cool the room and control the humidity in the air. It’s also higher in cost and extremely dangerous for health.

Running on low freon can cause permanent damage to air conditioners, so it’s best to fix these issues immediately. 

Types Of Freon Gas

Freon is widely used around the world. Freon is a manufactured greenhouse gas that is used in refrigerators and air conditioners. There are different types of Freon gas. 














Advantages Of Using Freon 

Freon is widely used around the globe in cooling systems. Even though environmentally freon is incredibly harmful, it has advantages as well. Here’s a list of advantages of using freon gas

 It helps cool the air of a room.

It makes it easier to breathe for asthma patients. 

Keeps insects and bugs away

Controls the humidity of a room

Helps with work performance 

It helps get better quality of sleep.

Freons Used In Residential Cooling

Freon gas sucks the heat out of space and releases it into the outside environment. There are many different types of Freon gas, but not all of them can be used in residential cooling. 

Freon gas used in residential cooling has to be safer than the rest as it’s a safety concern. R-22, R410A are 2types of freon gas. These gases are considered safe enough to use in residential cooling. These gases are also called Puron at times.

Can Inhale Freon Cause Health Problems?

Inhaling Freon has a massive impact on your health. Unlike most gases, it doesn’t just get used up. It stays forever in your body’s cells, which is risky and can cause long-term health problems. 

Freon poisoning is a severe health condition. It can cause:



Skin problems 

Eye problems 

Brain damage: Prolonged exposure to freon can cause severe brain damage. 

Not only does is it harmful to us, but it’s also harmful to the environment. Therefore, spilt freon should be treated as a dangerous situation, and everyone on the premises should evacuate immediately. 

Is It Possible For Freon To Combust?

Even though freon causes tons of environmental problems and health problems for humans, it doesn’t combust.  

Freon isn’t flammable. However, there have been times when a freon cylinder explosion has caused multiple problems. This is why one should always be careful while handling freon. Freon should only be handled with expertise and caution otherwise. Accidents might occur and harm many people.

Is Freon A Refrigerant?

Freon is also known as refrigerant. Freon gas is used to cool the air of a particular space and control the humidity as well.

Gases that help cool a particular area and push the warm air into the outside environment are called freon/refrigerants. 

Is Freon A Natural Gas?

Freon is a type of gas that works in cooling a specific area. It is not natural gas. Instead, freon is an artificial greenhouse gas that absorbs hot air and humidity and helps with cooling.

Ammonia is also a gas that helps maintain a specific room temperature; however, ammonia is natural gas, and it does not harm the environment at all.

Is Freon Better Or Ammonia?

Freon is an artificial greenhouse gas. On the other hand, ammonia is natural. 

Freon is more potent than ammonia when it comes to the cooling process. However, ammonia is more nature-friendly and doesn’t cause any environmental problems. Freon was developed as an alternative to sulfur dioxide and ammonia. Even though it is less efficient on a BTU per pound basis, the freon refrigerants work better and faster. 

Side Effects Of Freon On The Environment 

Freon is a manufactured greenhouse gas that indicates how deadly it is for the earth and its environment. In the last couple of years, the earth has struggled with greenhouse gas problems and melting earth caps. One of the main reasons behind this issue is CFC. CFC works by depleting the ozone layer, and it’s also a freon gas. 

With everyone using air conditioners and refrigerators, the use of CFC is increasing rapidly, which is leading the earth into catastrophe. 

How Long Does Freon Last?

Freon is not natural gas. It was made by humans, which makes a manufactured gas. Freon is also a greenhouse gas. Greenhouse gases harm our environment badly and are responsible for depleting the earth’s ozone layer.

Freon lasts in the air forever. Unlike most gases, it does not get used up or evaporate. It lingers in the air, and as it does not have its smell, it is very hard to identify. 

How Is Freon Used In Air Conditioners?

Almost everyone knows that freon is a refrigerant. We know it helps cool a room. However, the cooling process is more complex than most of us think. 

There’s a compressor in the air conditioners. It compresses the freon with the help of a lubricant. Then the freon gas moves through a few coils, which helps lower the heat and convert it to liquid. Liquid freon is cold. The liquid freon flows through a type of expansion valve, which cools it even more—turning it into a gas. The cold gas then goes through a few more coils, allowing it to absorb the heat and lower the temperature of the room.  

This is how freon helps with cooling the temperature of a room.

Why Is Freon Bad For The Environment?

Freon is terrible for the environment because it’s CFC. CFC harms the earth’s ozone layer and is responsible for holes in the ozone layer. It traps heat in the lower atmosphere, which causes the weather to become warmer. CFC is a full greenhouse house. It harms the ozone layer tremendously. It is responsible for the ozone layer hole in the Antarctic. 

Does Freon Have Its Weight?

Freon is an artificial refrigerant. It has a shelf life of 10 years. But, unfortunately, it doesn’t have its colour or odour.

Freon is heavier than air. It sinks to the ground whenever there’s a freon leak. The area where there’s a freon leak is hazardous, and everyone in that area should evacuate the premises immediately, or else the situation can be fatal.

Alternative To Freon

The only less harmful alternative to Freon is Puron. Puron is also a manufactured gas, but it’s a lot less harmful to the environment. Air Conditioner companies started using this as an alternative to freon in 2020. However, it’s not used as much as freon as it is more expensive. 

Shelf Life Of Freon

Freon is a widely used refrigerant. It is used in refrigerators and air conditioners.  

Freon lasts about 10years in cylinders when it’s stored in dry clean and out of sunlight. The storage temperature also shouldn’t be higher than 126°F.


To answer your question about which gas is used in air conditioners, it’s freon, and it is still harmful to our environment, which is why we should try and opt for something less harmful. Freon is effective in cooling, but the harmful side is too much for our universe to take. Therefore, we have to keep in mind that keeping the earth safe is our priority.  

 We have to reduce our freon usage and opt for pure to keep environmental problems from rising.
