Carrier, a part of Carrier Global Corporation, has announced significant advancements in its cold climate heat pump technology. Following the successful completion of the Department of Energy’s (DOE) Cold Climate Heat Pump Challenge, Carrier has updated its AHRI ratings, establishing itself as an industry leader in efficiency and performance. Carrier first commercialized its DOE cold climate heat pump by opening orders in 2024.

Carrier's Infinity Variable-Speed Ultimate Cold Climate Heat Pump with Greenspeed Intelligence now features an impressive 21.2 SEER2, 13.5 EER2, and up to 10.5 HSPF2. Based on these metrics, it is the highest rated DOE cold climate heat pump in the market. This leap in efficiency promotes superior energy savings while maintaining optimal comfort levels, even in the harshest climates.

Engineered to operate reliably down to -23 degrees Fahrenheit with 100% heating capacity at 0 degrees Fahrenheit, Carrier's cold climate heat pump provides consistent heating performance in extremely cold conditions. This remarkable capability helps reduce the reliance on secondary heating sources, offering homeowners a dependable solution for year-round comfort. Additionally, with sound levels as low as 55 decibels, Carrier's cold climate heat pump is among the quietest in the industry, offering  a peaceful and comfortable indoor environment.

“The updated AHRI ratings reflect Carrier's commitment to innovation and excellence in HVAC technology,” said Braden Cook, senior director of product management, training and service at Carrier. “These ratings confirm that Carrier's cold climate heat pump not only meets but exceeds industry standards, offering homeowners the best in efficient, quiet operation, and low-temperature performance.”
