Over the following 15 years, the HVAC industry will need to reduce hydrofluorocarbons (HFCs) by 85% in order to cut greenhouse gas emissions. Many manufacturers will stop using R410a refrigerants in order to accomplish these objectives. R-454B will be used in new cooling systems as of January 1, 2023. Your system most likely used R-22 refrigerant, which is no longer permitted for import into the US, if it was installed prior to 2010. It is very expensive even though it is available. Manufacturers will stop producing if your system is newer and uses R410A refrigerant in 2024, and replacement costs are anticipated to rise significantly.
With negative effects on the environment, air conditioning demand has skyrocketed worldwide. HVAC helping the environment. In order to reduce greenhouse gases, the Environmental Protection Agency was mandated to address hydrofluorocarbons, also referred to as HFCs. In December 2020, President Trump signed the AIM Act into law.
You might not need to worry about the most recent required type of refrigerant if your HVAC system is serviced and maintained. However, it might not be a simple process to add refrigerant to your HVAC system when it runs out or needs repairs starting in 2024. The new R-454B cannot replace the older refrigerants if your system uses R-22 or R-410A.
