Why is R-33 refrigerant no longer recommended?

R-22 is known to be a greenhouse gas and a contributor to ozone depletion. In 1987, the Montreal Protocol was created, which led to the phase-out of ozone-depleting substances, including R-22. As a result, the production and import of R-22 in the United States was reduced in phases, and it is no longer being manufactured as of 2020.

​

Since R-22 is being phased out, it is becoming increasingly difficult and expensive to obtain, and alternative refrigerants, such as R-410A, are being used instead. R-410A is a hydrofluorocarbon (HFC) refrigerant that has a lower impact on the environment and is considered more environmentally friendly than R-22. It is important to note that if your air conditioning system was designed to use R-22, you may need to replace the entire system or retrofit it to use an alternative refrigerant.
