R453A
(also known as RS-70 or RS-44B) is a non-flammable, high-purity, HFC-based retrofit refrigerant designed as a direct "drop-in" replacement for R22 in air conditioning and refrigeration, with a GWP of 1664, zero ODP, and no oil change required in most systems. It offers similar pressure/temperature profiles, operates down to , and is compatible with mineral, alkylbenzene, and POE oils.
Key details about R453A include:
- Applications: Ideal for residential/commercial A/C, heat pumps, and medium-temperature refrigeration (e.g., walk-in coolers, display cases).

Why was R-410A discontinued?
Key Reasons for the Phase-Out
- High Global Warming Potential (GWP):R-410A traps significantly more heat in the atmosphere than carbon dioxide (CO2), with a GWP of around 2,088.
- Climate Change Impact:Leaks of R-410A release this powerful greenhouse gas, accelerating global warming.
- Regulatory Mandates:The Kigali Amendment to the Montreal Protocol and the American Innovation & Manufacturing (AIM) Act of 2020 in the U.S. direct the HVAC industry to transition away from high-GWP substances.
The Transition
- New Equipment:As of January 2025, production and import of R-410A for new residential and commercial HVAC units are prohibited in the U.S., with systems now using more eco-friendly refrigerants.
- Continued Use (For Now):R-410A can still be used to service existing systems, but supplies will become scarcer and more expensive over time.
- Gradual Reduction:The overall production and consumption of R-410A will be steadily reduced until it's phased out completely by around 2040.
What This Means for You
- New Systems:Any new air conditioner or heat pump installed now will use a lower-GWP refrigerant, such as R-32 or R-454B.
- Existing Systems:If you have an R-410A system, it's still functional, but future repairs or recharges may become more costly as the refrigerant becomes less available.
