Fort Wayne, Ind.-based WaterFurnace International reported that its labs are now Energy Star accredited by the Environmental Protection Agency.

The manufacturer says it is the only HVAC equipment manufacturer in the United States to attain the recognition for its in-house testing facilities.

WaterFurnace officials said the recognition will improve the national and global reputation of WaterFurnace’s engineering laboratory. Lab reports generated at the company’s Fort Wayne facility can now be accepted directly by other compliance organizations, such as the EPA, the U.S. Department of Energy and the British Department of Energy and Climate Change, officials said.
