Carrier Sets Benchmark with First U.S. DOE-Validated 10-14-Ton Commercial Rooftop Unit

System performance delivers lower operating costs, efficiency gains and smarter energy use for commercial buildings

PALM BEACH GARDENS, Fla., Sept. 11, 2025 /PRNewswire/ -- Carrier Global Corporation (NYSE: CARR), global leader in intelligent climate and energy solutions, today announced it is the first HVAC original equipment manufacturer to complete the U.S. Department of Energy's (DOE) Commercial Building HVAC Technology Challenge laboratory validation in the 10–14-ton rooftop heat pump category. The Carrier system met or exceeded all challenge requirements, including heating capacity and energy efficiency test standards — delivering 100% heating capacity at 5°F, exceeding 70% heating capacity at -10°F and meeting or surpassing DOE's commercial HVAC efficiency thresholds.

"This milestone is about performance that pays," said Heidi Gehring, Managing Director, Light Commercial, Carrier. "Customers can realize lower energy bills with reliable comfort, while utilities benefit from a more efficient system that helps support grid reliability. This achievement reflects the work of our talented engineering and product development teams, who delivered a solution that reduces energy intensity and operating costs while helping strengthen U.S. competitiveness in commercial buildings."

The DOE's Commercial Building HVAC Technology Challenge is designed to accelerate adoption of high-performance equipment that reduces energy use and operating costs while supporting grid reliability through lower demand. Carrier's validated rooftop unit exceeded key efficiency and performance benchmarks in independent testing conducted by DOE, Oak Ridge National Laboratory and the National Renewable Energy Laboratory.

"Carrier is proud to be leading the way in developing next-generation rooftop units that deliver greater efficiency and reliability," said Gehring. "Innovating to meet the needs of our commercial partners builds on the legacy that began with Willis Carrier's invention of modern air conditioning and carries forward our tradition as the leader in intelligent climate and energy solutions."
