Carrier’s new 10-14-ton rooftop heat pump unit has been installed at a large national retailer in upstate New York as part of ongoing field trials. The system was the first in its range to complete DOE lab verification testing, setting a performance benchmark for cold-climate commercial rooftop systems by delivering 100% heating capacity at 5°F, more than 70% heating capacity at -10°F and performance that meets or exceeds DOE’s commercial HVAC efficiency thresholds.

In addition, Carrier’s 15-ton rooftop unit is undergoing testing at the DOE’s Oak Ridge National Laboratory in Tennessee and is expected to begin field trials at a commercial facility in Pennsylvania in the coming weeks. These trials will be monitored and verified by the National Renewable Energy Laboratory and are expected to conclude in summer 2027. Commercial availability is anticipated in summer 2027.             

The DOE’s Commercial Building HVAC Technology Challenge is designed to accelerate adoption of advanced HVAC equipment that lowers energy use and operating costs while supporting grid reliability through lower demand. The program includes two light commercial product categories — 10-14 tons and 15-25 tons — with Carrier participating in both as part of its broader commitment to innovation and helping customers reach their sustainability and cost-saving goals.

Across independent testing conducted by the DOE, Oak Ridge National Laboratory and NREL, Carrier’s rooftop heat pump systems have met or exceeded targets for IVHE, IVHEc and COPs, reinforcing confidence in their readiness for scaled commercial deployment, including strong cold-climate operation.
