Energy efficiency in split-type, free-discharge, and ductless air conditioners. Limits, testing method, and labeling.

Establishes the minimum Seasonal Energy Efficiency Ratio (SEER) level that split-type, free-discharge, and ductless air conditioners must meet. This applies to split-type, free-discharge, and ductless air conditioners (known as minisplit and multisplit); simple cycle (cooling only) or reversible cycle (heat pump), which use electrically powered, air-cooled condensers with nominal cooling capacities from 1 Wt to ​​19,050 Wt and operate by mechanical compression.
