President Barack Obama has signed a bill making changes to commercial refrigeration standards.

The bill, called the American Energy Manufacturing Technical Corrections Act, modifies the standards for service-over-the-counter commercial refrigerators that the Air-Conditioning, Heating and Refrigeration Institute said had been in place for more than a year. It cements standards for small-duct, high-velocity systems and makes other technical corrections. It also creates uniform testing and descriptions for water heater efficiency.

The AHRI, which had pushed for the bill’s passage, cheered its passage.

“We are grateful for the strong support and hard work on this bill by several of our member companies, as well as our legislative staff and the many cosponsors in the House and Senate,” said AHRI President and CEO Stephen Yurek. “This is common-sense legislation that will go a long way in helping our member companies as they work to rebuild our economy.”
