Why is Trane Changing Refrigerants? Learn Why Technology and Sustainability Go Hand in Hand

Home heating and cooling is adapting to new refrigerants to charge the HVAC systems of tomorrow – and help the fight against global warming.

February 9, 2024

Industries worldwide are embracing green solutions in response to environmental concerns. The HVAC industry, in particular, is undergoing a transformative shift towards sustainability, highlighted by the transition to more environmentally- conscious refrigerants. These refrigerant changes promise a greener future and redefine how we heat and cool our spaces in a way that benefits the planet.

Trane’s Commitment to Sustainability

Trane, in alignment with global environmental goals and new federal regulations, is committed to transitioning to low global warming potential (GWP) refrigerants in HVAC products by 2025. Trane’s refrigerant selections go beyond regulatory compliance, aiming for a greener future by introducing heat pumps, air conditioners, and additional products with 78 percent less global warming potential.
By leveraging innovative technologies and sustainable practices with eco-friendly HVAC choices, Trane is focusing on creating a better future for both homeowners and the environment, by reducing carbon emissions and increasing energy efficiency. Transitioning refrigerants is an important step in this process.

Why Is Refrigerant Part of This Transition?

Refrigerant is used in refrigeration and air conditioning systems to transfer heat and facilitate the cooling process. It absorbs heat and moves it in or out of the home to help maintain the desired temperature.

Refrigerants traditionally have contained hydrofluorocarbons (HFCs). HFCs are potent greenhouse gasses that contribute to global warming when released into the atmosphere. They have a high GWP, meaning they have a significantly greater impact on climate change when compared to carbon dioxide. The use of certain refrigerants over the years has contributed to environmental challenges, such as global warming, and Trane is taking the lead in addressing this issue by transitioning to a next-generation refrigerant with significantly reduced GWP.

Countless Hours of Research for High-Performance, Low GWP Alternatives

Trane is taking a phased refrigerant transition approach for 2024, kick-starting with the adoption of R-454B refrigerant in its residential products, beginning with the 15 SEER2 heat pump. The phased approach will assure homeowners that all units will surpass safety standards. Notably, electric-powered heat pumps, renowned for their energy efficiency, qualify for attractive incentives and rebates under the Inflation Reduction Act and Energy Efficient Home Improvement Tax Credit.

Although it’s new to homeowners, the R-454B refrigerant has already demonstrated exceptional performance during Trane’s field trials in the U.S. Department of Energy’s (DOE) Cold Climate Heat Pump Challenge. By rigorously testing products and introducing the latest innovations, Trane has been able to surpass the DOE’s requirement for high-efficiency heating in freezing temperatures. All in all, R-454B offers an excellent, more eco-friendly alternative to the older R-410A refrigerant.

Refrigerant Innovation for a Better Tomorrow 

With resolute determination and pioneering innovation, Trane is bringing 2030 Sustainability Commitments into action. Embracing the Gigaton Challenge, the company aims to reduce customer emissions by an astounding billion metric tons. Additionally, it has pledged to achieve net-zero carbon emissions by 2050, a commitment validated by the Science Based Targets Initiative (SBTi). Through these remarkable initiatives, Trane continues steps towards a greener future and is here to help homeowners every step of the way.
