Carrier WeatherExpert Rises to Department of Energy Challenge

SYRACUSE, N.Y. — The new Carrier WeatherExpert 10-ton unit exceeds the parameters of the recent Department of Energy Rooftop Unit Challenge, providing an Integrated Energy Efficiency Ratio of 20.8 – more than 15 percent more efficient than the required minimum of 18.0 IEER.

In an effort to spur the market introduction of cost-effective, high-performance commercial rooftop air conditioners. the DOE created the RTU Challenge, enlisting manufacturers to develop a 10-ton unit that meets the 18.0-IEER specifications by April 1, 2013. The DOE focused on rooftop units which are used in nearly half of all commercial cooling systems in the U.S. If all the 10-ton units currently sold nationwide were built using this new 18.0 IEER criteria, businesses would reduce energy use by half compared to current equipment, saving about $40 million annually in energy costs.

“When the DOE announced its RTU Challenge, we accepted immediately and enthusiastically,” stated Greg Alcorn, vice president, commercial sales and marketing, Carrier. “Carrier is committed to developing energy efficient solutions, so this challenge aligned perfectly with our priorities and market position. The DOE has taken a big step forward in improving the efficiency of the commercial cooling industry with the RTU Challenge, and Carrier is proud to be at the forefront of that movement.”

Their entire line of WeatherExpert models range from 3- to 23-ton units reaching a high-IEER rating of 21.0.  To learn more about Carrier’s energy management solutions, visit
