METUS Announces New Low-GWP VRF Line Using R-32 Refrigerant for Commercial Applications

SUWANEE, Ga.--(BUSINESS WIRE)--Mitsubishi Electric Trane HVAC US (METUS), a leading supplier of all-electric, all-climate Ductless and Ducted Mini-split and Variable Refrigerant Flow (VRF) heat pump and air-conditioning systems, today announced its new commercial VRF product line, which uses a low-global warming potential (GWP) refrigerant. Developed in anticipation of evolving refrigerant regulations across the industry, the new products will be available in selected markets in early 2026.

This new line will utilize R-32 refrigerant, a next-generation refrigerant with a low GWP. METUS is committed to developing products that utilize low-GWP refrigerants to uphold the company’s values of environmental stewardship and align with global efforts to phase down high-GWP refrigerants as mandated by the American Innovation and Manufacturing (AIM) Act. Starting Jan. 1, 2026, low-GWP, A2L refrigerants such as R-32 will be the new industry standard for Variable Refrigerant Flow (VRF) systems.

“As the HVAC industry navigates this important refrigerant transition, we are committed to helping building owners, engineers, contractors, and facility managers embrace more sustainable technologies without compromising performance,” said David Archer, Vice President of Commercial Business, METUS. “R-32 offers a balance of efficiency and reduced environmental impact, playing a critical role in the industry’s shift to lower-GWP refrigerants.”

In addition to adopting R-32 refrigerant, METUS’s new commercial VRF solutions are designed with a host of enhancements in efficiency, serviceability, reliability, and overall comfort. The systems feature built-in sensors capable of detecting refrigerant leaks in indoor units. The sensors can automatically stop refrigerant flow to connected indoor units, providing an added layer of safety and peace of mind.

Enhanced cooling integrated energy efficiency ratio (IEER) ratings and stronger heating coefficient of performance (COP) scores may increase energy savings and contribute to reduction in operational costs for building owners. Expanded performance across a wider temperature range will provide consistent comfort in more environmental conditions, while improvements in serviceability and simplified installation are expected to streamline setup and maintenance, minimizing labor and downtime. Finally, durability upgrades strengthen system resilience for long-term reliability and performance over the equipment lifespan.

For the first half of 2026, METUS will continue to provide VRF products with R-410A refrigerant while R-32 refrigerant products are being introduced, providing contractors, engineers, and building owners with VRF application and installation options.
