What is Freon?

Most people would agree that one of the best appliances ever invented is the air conditioner. If you live in Florida where it is mostly warm all year round are probably vehemently nodding your head now in agreement with this statement. 

Air conditioning has been around for so long that many young people do not even remember what it was like to battle the heat of extremely hot does with a cold drink and a fan. The only heat people have to experience these days if they don’t want to do outdoor activities on a hot day is the walk from their home to their car and then from their car to their workplace and vice versa. Nowadays there seems to be air-conditioned refuge wherever we go. All of this is due to some innovative technology and a mysterious substance called Freon. What is Freon? You are about to learn more about this important catalyst in the air conditioning process.

What is Freon and What Does It Do?

Freon is actually a company trademark product that became what is known as a proprietary eponym because of its widespread popularity, much in the way that many people say give me a ‘Kleenex’ instead of saying give me a ‘tissue’. By definition, Freon is a Chlorofluorocarbon compound that was once commonly found in many aerosol propellants, refrigerants, or organic solvents. Freon is a substance that does a great job of absorbing environmental heat and once it has been run through an air conditioning system’s compressor and evaporators, it provides much cooler air. 

What role does freon play in an air conditioning system? Freon starts to work by its presence in the copper coils of an air conditioning system. As was mentioned, it is in these coils that the Freon in an AC system starts to absorb heat. This causes the Freon to change from a low-pressure gas to a high-pressure liquid. As the Freon progresses through the components in an air conditioning system, it eventually cools down and turns back into a low-pressure gas. Forced air being blown over this part of an air conditioner’s coils results in the cooler air that is pushed into a home or building to make it more comfortable on a hot day. Although it sounds simple, it’s a pretty sophisticated process.

Modern-Day Air-Conditioning Systems Use Less Harmful Freon Derivatives

With all the benefits that we have gotten over the years from Freon and its use, it has one major drawback. That is, it’s is thought to be one of the leading causes of ozone layer depletion when it leaks into the atmosphere. Obviously, this is a huge concern for all of mankind. That’s why scientists and researchers have worked to come up with much less harmful forms of air conditioning refrigerant than Freon. Freons used in aerosol propellants actually do more harm than those found in air conditioners because they escape in the atmosphere much easier. 

Here are some modern-day refrigerants that are used in place of Freon:

  • R-134A
  • R-407C
  • R-404A
  • R-410A

You must also be aware that freon derivatives are not interchangeable. They are designed with specific traits that make them ideal in certain types of situations where the air conditioning process needs to take place. Changing out refrigerant is not something that needs to be done anyway because freon derivatives have an unlimited useful life. The only time you need to add more Freon is when some is lost due to leaking in a system. If that’s the case with your AC, then it’s better to have a professional HVAC technician remedy that situation anyway. So don’t believe mechanics and HVAC businesses that advocate the need to ‘recharge’ your air conditioning refrigerant on a periodic basis.
