Reviews of The Top R-22 Freon Refrigerant Alternatives


About 28 years ago, it was discovered that the common hydrochlorofluorocarbon refrigerant R-22, was not healthy for the environment and so, the Environmental Protection Agency (EPA) began to phase out the substance and ultimately ban it. The phasing out of this ozone-layer depleting refrigerant started back in 2010 and further phasing out was done in 2015. By January 1st, 2020, the use of R-22 Freon will be severely limited by halting its manufacture and by 2030, it will be illegal to use the substance.

As more and more people work to ascertain their refrigerant-based equipment and machines will continue to work in their worksites, commercial settings, and home, they have turned to eco-friendly, cost-effective and more efficient R-22 alternatives. With an aim to help those who are looking to help phase out this ozone-layer depleting substance, we have put together a piece that looks at some of the best R-22 alternatives. It is important to note that each of these refrigerants have their own ups and downs as well as safety precautions that should all be factored in.


Norflurane, commonly known as R-134A, is a haloalkane substance with thermodynamic properties. It is made of a single competent, unlike most R-22 alternatives. Due to this reason, the refrigerant doesn’t require the utilization of several recovery devices.

According to the EPA regulations, any unit utilizing a blend needs a separate machine for every component. As of this writing, R-134A is the only approved alternative to retrofit R-12 AC units in cars, which is its primary use. However, retrofitting ought to follow instructions to the letter in order to avoid safety hazards and other issues.

Retrofitting is a relatively simple procedure. It usually involves replacing the car’s receiver or accumulator, getting rid of the old compressor oil and replacing the AC’s high-pressure switch. However, even though it is an easy procedure, it’s still imperative to do it thoroughly and carefully. If any Freon is left in the system, it could lead to cross-contamination.

This type of contamination can make the cooling system less efficient and might increase the compressor head’s pressure to alarming levels, that only results in system failure. In addition, the refrigerant R-134A needs a special oil blend of polyester or polyalkene.

This type of refrigerant is considered safer for the environment as most experts believe it has an insignificant effect on the ozone layer. However, some countries are not convinced that it’s the best alternative to Freon and is being phased out as well. Regardless, it is still available in the US and can be bought in most Auto Shops.


Refrigerant 407C is a common alternative for those who want to retrofit their Freon equipment as the substance has thermodynamic properties that are almost similar to those in R-22.

Hydrofluorocarbons mixture includes a combination of difluoromethane, 1,1,1,2-tetrafluoroethane and pentafluoroethane. This alternative is widely accepted, and it’s commonly found in packaged air conditioners, ductless split systems, light air conditioning and direct expansion systems in industrial, commercial and residential settings as well as in water chillers. This type of refrigerant is ideally used in medium temperature refrigeration units.

R-407 is known to be safe for the environment as it has an Ozone Depletion Potential of 0. It is available in both drums and cylinders and can be bought from refrigerant & gas suppliers, many of which can be found in sites like Amazon.


This is another widely accepted alternative to Freon. Just like R-134A and R-407 C, it has an Ozone Depletion Potential of Zero. R-404A is usually used in refrigerant units that need a temperature between -49 and 59 degrees Fahrenheit which translates to -45 and 15 degrees Celsius. Due to its wide temperature range, it’s ideal for use in the industrial and commercial transport industries.

R-404A makeup is quite similar to Freon and sometimes gives an improved performance. Since it has no rapid reaction to air and water, it is considered safe for numerous applications. It is ideally colorless, odorless and non-flammable.

However, as with any other refrigerant out there, it is important to take the appropriate safety precautions. Direct contact with this substance can cause frostbite and exposure to high heat or fire for long periods can make the tank to bust. This refrigerant is also common and available for purchase in stores that deal with heating and cooling products. You can also easily find bluon energy tdx 20 refrigerant review.


This one is a blend of difluoromethane and pentafluoroethane. It is ideally safe for use in regard to the environment and provides significantly better efficiency compared to R-22 and R-407C.

Refrigerant 410A is considered to be an ideal alternative to R-22 because of its higher pressure as well as refrigeration capacity which leads to better performance. If you decide to buy AC units that utilize this refrigerant, the process should be easy. As a matter of fact, most of the companies that manufacturer AC units, make systems specifically for use with this substance.

However, even though it is popular in commercial air conditioning, refrigeration and chilling units, it’s imperative to note that R-410A won’t work with R-22 units. That is because it has a higher pressure and so, it needs a different manifold pressure gauge.

R-401A should be charged only in short bursts and in its liquid form. It is sold under various trademarks including Genetron R410A, Puron, Suva 410A, EcoFluor R410 and AZ-20. It is relatively easy to purchase online as well as in specialty heating & cooling stores.

These are the most common and safe alternatives to the refrigerant R-22. Deciding on which to use will depend on your unit and budget. If you are not certain or do not know much about refrigeration and air conditioning units, you may want to consult a professional in the field for assistance. It is a good idea to replace or retrofit your units as soon as you can as the deadline for R-22 is drawing closer and closer. It is also worth noting that R-22 prices will only rise due to the halt of its production.
