replacing R22 refrigerant

R22 has been a coolant of choice for home appliances such as freezers, refrigerators, and air conditioning units for decades. However, with its phase-out deadline approaching quickly in 2020, many manufacturers are no longer producing it. Consequently, its prices are skyrocketing, making it necessary for users to look for alternatives.

However, the R22 replacement has had its own challenges. Chiefly, alternative options have been very expensive and time-consuming, many times requiring users to buy new equipment altogether. Another big problem is the difficulty of finding replacements that work as effectively and efficiently in old systems as R22.

Today, there is hope for those with old systems. Many companies have and continue to develop improved coolants that closely resemble the features of R22. Moreover, they do not require system component or oil changes. Some of them have the following advantages:

  1. Same flow rate as R22.
  2. Similar discharge pressure as R22.
  3. Lower discharge temperature which may prolong compressor life.
  4. Lower global warming potential (GWP) and less or zero ozone depletion capability.
  5. Lower energy consumption.
  6. Almost similar cooling capacity with R22 in refrigerators and air conditioning units.
  7. The flexibility of operating in all kinds of systems and compressors.
  8. Not harmful to systems in case of inadvertent mixing with R22.
  9. Non-flammability.

Lubricant Compatibility

Common replacements for R22 are compatible with traditional minerals, polyol ester lubricants, and alkyl benzene oils. Therefore, there is no need to retrofit to different refrigerant oil. Consequently, the non-use of hygroscopic synthetic lubricants prevents the risk of moisture entering into the refrigeration system.

Also, replacements containing little amounts of hydrocarbons improve oil return to compressors. This extends the components’ life. Overall, manufacturers have developed alternative refrigerants with features that make R22 replacement process less costly to consumers. 

Compatibility With Materials

It’s important to replace your r22 refrigerant today with compatible materials that manufacturers use to build refrigeration systems. In other words, there is no difference in material compatibility between R22 and modern coolants. Replacing the traditional reagent is, therefore, hassle-free and cost-effective.

Nonetheless, before attempting to replace R22, it is wise to be informed. Check manufacturer’s retrofit literature for the specific equipment they are using to understand materials’ compatibility. Otherwise, it may cause damage to the equipment.

Checking the compatibility of refrigerants requires advanced knowledge. Working with professionals would make the process much easier and safer. They have worked on different equipment and know the ins and outs of R22 replacement.

Environmental Sustainability

Current refrigerants do not contain chlorine. That means they do not deplete the ozone layer. They do have a direct GWP, but it is much lower than that of R22. Therefore, they enable owners to comply with environmental regulations and confident when using them.


In compliance with global regulations for environmental sustainability, most companies are no longer producing R22. It has become extremely expensive. Fortunately, modern replacements are acceptable, and manufacturers produce them in large quantities. The alternatives are readily available and much cheaper.

Hiring Professionals

Replacing R22 refrigerants is a simple process. However, going the DIY way is risky and involving. Calling professionals is wise. When choosing a company for R22 replacements, users must look for experience, reliability, affordability, and a good history.
