The efficiency of air conditioners is often rated by the Seasonal Energy Efficiency Ratio (SEER). The higher the SEER rating of a unit, the more energy efficient it is. Mitsubishi Electric models feature one of the highest SEER ratings in the industry.

Some models may qualify for government incentives. Please contact your local dealer for more details.
