## Abstract

The Department of Energy (DOE) is amending its test procedure for residential central air conditioners and heat pumps. This final rule implements test procedure changes for small-duct, high-velocity systems, two-capacity units, and updates references to the current American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) standards. Today's rule also clarifies issues associated with sampling tested systems and rating untested split- system combinations.
