Which refrigerant will new Trane residential products use?

R-454B is the newest refrigerant, which will gradually replace R-410A, the refrigerant used in HVAC manufacturing from 2010 until the phase-out is complete in January 2025. R-454B is a blend of R-32, a hydrofluorocarbon (HFC), and R-1234yf a hydrofluoroolefin (HFO). This blend enables maximum energy efficiency and performance while also reducing the potential for environmental impact.

Can R-454B be retrofitted into systems using R-410A?

No. R-454B is not compatible with older systems. That’s why the EPA is phasing out manufacturing units using R-410A but is still allowing it to be used in existing systems.

What is a refrigerant?

An HVAC refrigerant, or AC refrigerant, is a liquid or gaseous cooling compound that helps your air conditioner or heat pump cool your home in the warmer months. During the refrigeration cycle, refrigerants absorb and transfer heat to the outside. There are many other refrigerants used in car air conditioning, home refrigerators, and commercial applications.

How long will R-410A refrigerant be available?

R-410A will be available for years to come, and there will also be a supply of recovered R-410A as people replace aging AC units. In addition, HVAC manufacturers will have an inventory of heat pumps and air conditioners that use this refrigerant which they can continue to sell until inventory is depleted.
