Important Information For All Air Conditioning Equipment
The EPA has mandated that all air conditioning equipment manufactured after January 1, 2025 use R-454B refrigerant.
R-454B has a significantly lower Global Warming Potential (GWP) than R-410A. There are no ozone-depleting compounds, it has low toxicity compared to past refrigerants, and it has proven to be more energy efficient in the US Department of Energy testing.
FAQs on The EPA’s Latest Refrigerant Change
Can I still buy a R-410A system?
Yes, but only for a limited time. HVAC manufacturers are shifting production to R-454B systems, and R-410A models will no longer be available after the transition. If you buy an R-410A system now, you may face limited availability for servicing and equipment in the future.
Do I need to replace my current system?
No, you do not need to replace your current system as long as it still runs efficiently.
If you still have an R-22 system, we no longer provide this refrigerant due to the phase-out being complete.
If you have an R-410A system, replacement parts and the refrigerant are currently available.
In either case, as your system ages and nears replacement or begins to require costly repairs, you will need to consider your options.
Can you retrofit my current system?
Most systems currently installed do not meet the system requirements for R-454B, so retrofitting is highly unlikely.
Installation changes with R-454B systems
Due to the EPA’s guidelines regarding R-454B, installation of your air conditioning equipment will look a bit different.
System piping (lines) – different sizes required
Concealed lines can no longer be used (hidden in wall cavities)
Additional leak sensors required
Permitting may be required
Carpenters may be necessary to gain access to run new lines
Servicing a R-454B system
Maintenance recommendations on R-454B systems remain the same as those of existing systems and will be available under our current cooling protection plan. Our technicians will be required to utilize some new tools and procedures to work with the refrigerant.
