SEER2
The U.S Department of Energy has raised the minimum rating requirements starting in 2023 that include updated testing conditions and metrics to better reflect real-world conditions. SEER2 (Seasonal Energy Efficiency Ratio) is a measurement of cooling efficiency over a typical cooling season. It is useful for comparing energy efficiency of cooling systems. The higher the SEER2, the more energy efficient the system.

The U.S Department of Energy has raised the minimum rating requirements starting in 2023 that include updated testing conditions and metrics to better reflect real-world conditions. EER2 (Energy Efficiency Ratio) is a measurement of cooling efficiency under fixed conditions. It is useful for comparing units that will operate consistently under one set of conditions (e.g. server room). The higher the EER2, the more efficient the system.
