While regulators are still discussing the exact date of implementation, HVAC specialists would be wise to prepare for the switch far in advance. Thus, by January 1, 2023, A2L refrigerants will be the new refrigerant standard for the United States. A2L refrigerants have been in use since 2018, and regulators quickly realized their broader efficacy relative to HFC refrigerants. However, A2L refrigerants have been designed to also offset the dangerous greenhouse effect – one of the major contributors to global climate change. In truth, HFCs were successful in protecting the ozone layer. Your first question may be, “Were HFC refrigerants not effective?” Now, HFC refrigerants are being phased out in favor of the new A2L refrigerant class. By 2010, all newly manufactured air conditioning systems required HFC refrigerants to reduce the impact of these chemicals on the ozone layer. Between the mid-1990s and 2010, refrigerant changes included the phasing out of CFC and HCFC refrigerants to protect the environment. Refrigerant Changes in Recent DecadesĪnyone familiar with the HVAC industry for the past few decades knows it has been subject to a host of new regulations.

In recent years, the HVAC industry has evolved as new changes and regulations continue to roll out nationwide.
