The most common refrigerants used for air conditioning over the years include: Chlorofluorocarbons (CFCs), including R12. This is known to contribute to the greenhouse gas effect. Hydrochlorofluorocarbons (HCFCs), including R22. Hydrofluorocarbons (HFCs), including R410A and R134. The result was a new class of chemicals called chlorofluorocarbons (CFC), a compound made of fluorine, chlorine and carbon atoms. Basic CFC is a non-toxic non-flammable gas with relatively high mass. It's a great refrigerant because it compresses easily to a liquid and carries away lots of heat when it evaporates. Carbon dioxide is present in the atmosphere and it is non-flammable and non-toxic. Despite the high pressures associated with its use, carbon dioxide has been used as a refrigerant since 1862. It is odourless, non-toxic, non-flammable, non-explosive and non-corrosive. Below, you will find four popular refrigerants that are safe and suitable alternatives to freon. 4 Types of Refrigerants That Are Safer Than Freon R-134A. Click Here to Buy R-134A on Amazon. R-407C. Click Here to Buy R-407C on Amazon. R-404A. Click Here to Buy R-404A on Amazon. R-410A. The most common refrigerants include Chlorofluorocarbons (CFCs), Hydrochlorofluorocarbons (HCFCs), Hydrofluorocarbons (HFCs), and Natural Refrigerants. Freons or halocarbons are synthetically produced. The refrigerant types that make the most common list include: R-134A. R-407C. R-404A. R-410A.

Freon is a tasteless, mostly odorless gas. When it is deeply inhaled, it can cut off vital oxygen to your cells and lungs. Limited exposure — for example, a spill on your skin or breathing near an open container — is only mildly harmful. However, you should try to avoid all contact with these types of chemicals.

Freon, on the other hand, has killed people because they simply couldn't associate the slight smell with danger, and they were asphyxiated. It kills you by displacing the oxygen in the air and as the oxygen level goes down, you begin to suffer from hypoxia and don't think rationally.

Refrigerant Flammability Classes Class 1 refrigerants are either non-combustible or, at 70 degrees F and 14. 6 psi (room temperature and sea-level atmospheric pressure), do not support the spread of a flame in a combustible environment of the gas outward from the point of ignition.

The most common HFC used in air conditioners is R-410A. This refrigerant is better than R-22 in terms of “Ozone Depletion” potential and energy efficiency, but it still causes global warming. A few more HFCs that are commonly used are: R-32 in Air Conditioners and R-134A in refrigerators.

R-134a is not a refrigerant blend. It is considered a pure compound and has only one molecule. The R-134a molecule is ethane-based and consists of carbon (C), fluorine (F), and hydrogen (H).

An ozone layer-friendly gas when it was introduced to Australia back in 1995, R134a is itself now perceived to be damaging to the environment. R134a has since been classified as a 'high global warming potential' gas. The chlorofluorocarbon-based R12 it replaced would be even more harmful if it had remained available.

Freon, also known as R-22, will no longer be made or imported to the United States, starting January 1st, 2020. The Environmental Protection Agency said the odorless gas, which is one of the key refrigerants in air conditioners, is bad for the environment because it depletes the ozone layer.

The refrigerant is a special fluid that changes between liquid and vapor at convenient temperatures for pulling heat out of air that's at about 75° F and dumping it into air that's above 90° F.

Freon is a dangerous substance. This almost odorless and tasteless gas can cause severe symptoms if a person inhales too much at once. Because refrigerants cut off the oxygen supply, some people use the gas to get high.

Use the water hose spray to clean off loose debris (grass, leaves, etc) on the outside unit. Spray the outside unit with the coil cleaner. Wait 10-15 minutes as the cleaner foams and bonds with the dirt on the coils. Rinse the coil cleaner off with the hose.

The EPA banned Freon (also known as HCFC-22 and R-22) for use in new systems back in 2010 after classifying it as an ozone-depleting substance. Through the Clean Air Act, new production and import of HCFC-22 will be banned in 2020.

R-12 refrigerant is one of the founding fathers of the refrigeration and air conditioning world. In others the refrigerant was too flammable for safe use like Propane and Isobutane.

There is now a direct replacement for R-12 on the market from Houston-based Pennzoil, called FR-12 and carrying the brand name FRIGC (pronounced frij-ik). Converting to FR-12 is a simple and relatively inexpensive process compared with the complicated conversions to the new R-134a refrigerant now used in all new cars.
