## Abstract

On January 5, 2017, the U.S. Department of Energy ("DOE") published a final rule that made two sets of amendments to the test procedure for central air conditioners and heat pumps ("CAC/HPs"): amendments to the existing test procedure required for determining compliance with the current energy conservation standards; and establishment of a new test procedure that would be the basis for making efficiency representations as of the compliance date for any amended energy conservation standards. This document corrects typographical errors, omissions, and incorrect cross-references in the Code of Federal Regulations that resulted from the January 2017 final rule. Neither the errors nor the corrections in this document affect the substance of the rulemaking or any conclusions reached in support of the final rule.
