The Air-Conditioning, Heating, and Refrigeration Institute will begin using a new unified mark to identify heating, ventilation, air conditioning and commercial refrigeration products that have achieved third-party certification of their performance ratings. The new mark will replace the ARI Performance Certified, GAMA Efficiency Rating Certified and I=B=R marks, but these changes will be made according to an implementation schedule that provides enough time to bring all certification programs into compliance with internationally recognized accreditations.
